As shown in fig. 1 to 7, in the present embodiment, the battery protection plate shaping device includes: a base 10; an accommodating space 20 provided on the base 10 and accommodating a battery; the cover pressing structure 30 is movably arranged relative to the base 10 and provided with an avoidance position and a pressing position, when the cover pressing structure 30 is at the avoidance position, the cover pressing structure 30 is separated from the base 10, and when the cover pressing structure 30 is at the pressing position, the cover pressing structure 30 is positioned above the base 10 and presses the protective plate of the battery; a support member 40 disposed on the base 10 at an end of the receiving space 20 where the battery head is received, the support member 40 extending into the receiving space 20, the support member 40 supporting the protection plate; wherein, when the cover pressing structure 30 is at the pressing position, the protection plate is located between the support 40 and the cover pressing structure 30.

By applying the technical scheme of the embodiment, the accommodating space 20 is arranged on the base 10, and the battery is placed in the accommodating space 20. The cover pressing structure 30 is movably arranged relative to the base 10, when the cover pressing structure 30 is separated from the base 10, the cover pressing structure 30 is at an avoiding position, and when the cover pressing structure 30 presses the battery protection plate, the cover pressing structure 30 is located above the base 10, and the cover pressing structure 30 is at a pressing position. A support member 40 is further provided on the base 10, the support member 40 being positioned at an end of the receiving space 20 where the battery head is received, the support member 40 extending into the receiving space 20 to support the protection plate. When the cover pressing structure 30 is in the pressing position, the protection plate is located between the support member 40 and the cover pressing structure 30. Through the arrangement, when the cover pressing structure 30 is used for bending the protection plate, the supporting piece 40 can play a supporting role on a part of the structure of the protection plate in the vertical space where the end part of the battery head is located, so that when the cover pressing structure 30 is located at the pressing position, the part of the structure of the protection plate in the vertical space where the end part of the battery head is located is prevented from being in a suspension state, and further after the cover pressing structure 30 is moved from the avoiding position to the pressing position, the part of the structure of the protection plate in the vertical space where the end part of the battery head is located can be kept flat.

After the cover pressing structure 30 moves from the pressing position to the avoiding position, the supporting member 40 leaves the accommodating space 20, and at this time, the supporting member 40 is at the avoiding position, so that the battery and the protection plate can be taken out from the accommodating space, that is, when the supporting member 40 is at the avoiding position, the supporting member 40 does not interfere with the taking out of the battery and the protection plate.

Preferably, the supporting member 40 is cylindrical, so that the supporting member 40 does not damage the protection plate and the bent edge of the protection plate can be smoothly transited.

The limiting member 70 has a limiting effect on the shaping block 60, and prevents the shaping block 60 from falling off in a direction away from the base 10 in the height direction. The spacing space 80 prevents the spacing member 70 from interfering with the movement of the shaping block 60, i.e. the spacing member 70 not only prevents the shaping block 60 from being separated from the base 10 in the height direction, but also enables the shaping block 60 to move smoothly.

The sectional area of the plastic head 61 in the vertical direction is larger than the sectional area of the connecting rod 62 in the vertical direction, so that the plastic head 61 does not fall off in the width direction of the base 10, and the movement of the plastic head 61 in the recess 12 is more stable when the plastic head 61 is in contact with the protection plate. The concave portion 12 enables the shaping head 61 to slide in the base 10, and when the shaping head 61 moves towards the direction close to the battery head, the protection plate can enter a gap between the shaping head and the battery, namely, the shaping head 61 can shape part of the structure of the protection plate in the concave portion, so that the fitting degree of the protection plate and the end part of the battery head is good. It should be noted that, the above-mentioned recess 12 is located at the side of the accommodating space 20 and is perpendicular to the direction from the accommodating space 20 to the cap structure 30. The recess 12 and the accommodation space 20 are adjacently disposed in a direction perpendicular to a direction from the accommodation space 20 to the cap pressing structure 30.

Preferably, the edge angle of the side surface of the shaping head 61, which is in contact with the protection plate in the concave portion 12, is smoothly transited, so that the shaping head 61 does not damage the protection plate when the shaping head 61 is in contact with the protection plate, and the contact between the shaping head 61 and the protection plate is softer, so that the protection plate in the concave portion 12 can gradually enter the gap between the shaping head 61 and the side wall of the concave portion 12, and the protection plate is extruded.
