Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to a storage battery with damping design, a large cover and a handle. Background Art

[0002] The handle design on the battery is not only convenient for users to carry the battery, but also needs to be able to adapt to some specific requirements of customers. For example, a well-known domestic OEM requires that when the battery is put into production, the battery is transported to the assembly station using a material rack, and the battery handle must be kept vertical during transportation. This allows the robot at the assembly station to pass through the handle directly, thereby improving the assembly efficiency of the entire vehicle. Therefore, the battery handle needs to have a certain ability to prevent falling after being vertical.

[0003] At present, after the battery cover handle is pulled up, it basically relies on its own balance to maintain the vertical state. After the battery handle is vertical, bumps, braking and other conditions during transportation may cause the handle to fall down, thereby affecting the assembly efficiency of the OEM and causing complaints to the battery supplier, thereby proposing the need to improve the stability of the battery handle in the vertical state. Summary of the invention

[0004] The utility model aims to improve the stability of a battery handle in a vertical state. In view of the deficiencies of the prior art, a handle damping device is provided without affecting the external dimensions of the battery to ensure that the vertical handle does not fall down during transportation.

[0012] A rectangular damping device, i.e., a damping boss, with a length of 10 mm, a width of 4.4 mm, and a height of 0.7 mm is designed just below the ear axis of the large cover for mounting the handle. The contact portion between the handle and the damping device is designed to be arc-shaped, so that the handle can smoothly contact the damping device when rotating. The handle is reserved with a recess for making way, so that when the handle is laid flat, the handle does not conflict with the damping device, ensuring that the handle can be laid completely flat. The beneficial effects of the utility model are: ensuring the normal use of the handle, while increasing the ability of the handle to maintain a stable state after being erected.

[0017] Figure 1-4In the middle, the large cover 2 has a groove for accommodating the handle, and an ear shaft 21 is provided on the side wall of the groove. A handle damping device (referred to as a damping bump) is provided directly below the ear shaft 21. The handle 1 includes a lifting rod portion located in the middle, and a supporting rod portion connected to both ends of the lifting rod portion. The ends of the two supporting rod portions are both prism structures, and the inner surface of the prism structure is provided with an axial hole 14. The two adjacent side surfaces of the prism structure are a positioning surface 12 and a bottom surface 15. The bottom surface 15 has a recess 11 designed to be offset from the damping bump, and the positioning surface 12 and the bottom surface 15 transition through an arc surface 13; the handle 1 is installed at the ear shaft 21 through the axial hole 14. The damping bump is a rectangular block with a length of 10mm, a width of 4.4mm, and a height of 0.7mm.

[0018] When the handle 1 is placed in the groove, the damping protrusion is placed in the yielding groove 11 on the bottom surface; when the handle 1 is erected upward, the damping protrusion contacts the arc surface 13; when the handle 1 is erected, the positioning surface 12 contacts the damping protrusion.

[0019] When the handle 1 is rotated from horizontal to vertical, the handle contacts the damping bump when the handle rotates to nearly 90°. At this time, the arc-shaped design of the handle contact surface (i.e., the arc surface 13) can ensure that the handle can continue to rotate to a completely vertical state (e.g., Figure 1 , 2 ). When the handle 1 is completely vertical, the damping protrusion will exert an upward force on the handle 1, thereby increasing the stability of the handle to maintain the upward vertical position.
