Description

Technical Field

[0001] The utility model relates to the technical field of battery boxes, in particular to a handle structure with damping and positioning functions for a battery box. Background Art

[0002] The battery case for an electric bicycle's lithium-ion battery typically consists of a lower shell and upper cover secured by screws. The internal structure of the shell primarily includes the battery module, battery management system, and connecting wiring harness. The battery module and battery management system are typically fixed in an integrated manner, either by directly attaching the battery management system to the battery module or by adding a plastic component to the battery module and securing the battery management system to the plastic component.

[0003] When the battery management system needs to be analyzed or repaired, the battery module and battery management system are fixed together, which requires removing the battery module and battery management system simultaneously and then disassembling the battery management system from the battery module. This repair method is relatively cumbersome. In addition, during use, especially when the vehicle is bumpy, the battery box handle will make noises, which will affect the performance of the battery box and the internal batteries over time. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a handle structure for a battery box with a damping sense and a positioning function, and adds a concave and convex platform, which makes product assembly simpler and does not require additional alignment screw holes; and the added damping function, combined with the concave and convex platform, prevents the handle from making noises when the vehicle is bumpy.

[0005] To achieve the above objectives, a handle structure with damping and positioning functions for a battery box is designed, comprising a battery box cover and a handle. The structure is characterized in that a groove is provided on the front upper side of the battery box cover, a handle is provided in the groove, and the end of the handle is connected to the upper part of the battery box cover by a stepped screw assembly;

[0006] The left and right sides of the upper part of the battery box upper cover are respectively provided with upper cover threaded holes, damping ribs are provided in the upper cover threaded holes, and a locking convex point is provided on one side of the upper cover threaded hole.

[0007] The battery box upper cover is a rectangular module structure.

[0008] The threaded hole of the upper cover is a stepped threaded hole structure, and the structure of the threaded hole of the upper cover matches the stepped screw assembly.

[0009] The locking convex point is a semicircular boss structure.

[0010] The handle is a U-shaped structure, with bolt through holes provided at the openings of the handle, and auxiliary positioning bosses connected to the inner sides of the openings of the handle, and a positioning recess provided on one side of the auxiliary positioning bosses.

[0011] The auxiliary positioning boss is a circular ring structure, and the auxiliary positioning boss and the bolt through hole are concentrically arranged.

[0012] The recessed points match the convex points.

[0013] The step screw assembly comprises a step screw and an embedded nut. The embedded nut is sleeved on the rod of the step screw and is arranged inside the threaded hole of the upper cover.

[0014] The rod of the step screw is stepped, the upper part of the step screw rod is a smooth rod, and the lower part of the step screw is a threaded section.

[0015] Compared with the prior art, the present invention provides a handle structure for a battery box with a damping feeling and a positioning function, and adds a concave and convex platform, which makes product assembly simpler and does not require additional alignment screw holes; and the added damping function, combined with the concave and convex platform, prevents the handle from making noise when the vehicle is bumpy.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] The structure of the utility model is mainly used to solve the problem that the battery and the handle 2 make noises when the vehicle is in a bumpy state.

[0025] like Figures 1 to 4 As shown, a groove is provided on the front upper side of the battery box cover 1, a handle 2 is provided in the groove, and the end of the handle 2 is connected to the upper part of the battery box cover 1 using a stepped screw assembly;

[0026] The left and right sides of the upper part of the battery box upper cover 1 are respectively provided with upper cover threaded holes 1-1, the upper cover threaded holes 1-1 are provided with damping ribs 1-2, and a locking protrusion 1-3 is provided on one side of the upper cover threaded hole 1-1.

[0027] The battery box upper cover 1 is a rectangular module structure.

[0028] The upper cover threaded hole 1 - 1 is a stepped threaded hole structure, and the structure of the upper cover threaded hole 1 - 1 matches the stepped screw assembly.

[0029] The positioning protrusions 1-3 are semicircular boss structures.

[0030] The handle 2 is a U-shaped structure, with bolt through holes 2-1 provided at the opening of the handle 2, and auxiliary positioning bosses 2-2 connected to the inner sides of the opening of the handle 2, and a locking recess 2-3 is provided on one side of the auxiliary positioning bosses 2-2.

[0031] The auxiliary positioning boss 2-2 is a circular ring structure, and the auxiliary positioning boss 2-2 and the bolt through hole 2-1 are concentrically arranged.

[0032] The locking concave points 2-3 are matched with the locking convex points 1-3. The structure in which the locking concave points 2-3 are matched with the locking convex points 1-3 can also be connected in other forms, for example, using an elastic structure connection.

[0033] The step screw assembly includes a step screw and an embedded nut. The embedded nut 4 is sleeved on the rod of the step screw 3, and the embedded nut 4 is arranged inside the threaded hole 1-1 of the upper cover.

[0034] The shaft of the step screw 3 is stepped, with the upper portion of the step screw 3 being a smooth rod and the lower portion being a threaded section. The step screw 3 can also be modified to other forms, such as a plastic structure or other material to connect the handle to the battery compartment cover 1.
