Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electric core charging and discharging test equipment, especially to an electric core charging and discharging test device convenient to clamp. BACKGROUND

[0002] The electric core refers to a single electrochemical core containing positive and negative poles, which is generally not directly used. The electric core is the power storage part in the rechargeable battery, which is different from the battery containing a protection circuit and a shell and can be directly used. The lithium ion secondary rechargeable battery is composed of an electric core and a protection circuit board. The rechargeable battery without the protection circuit board is the electric core. The quality of the electric core directly determines the quality of the rechargeable battery. When the quality of the electric core is detected, the electric core is charged and discharged for testing. The existing electric core charging and discharging test device cannot automatically adjust the position of the electric core and needs manual assistance, which is relatively cumbersome.

[0003] The Chinese patent application with publication number CN215449526U discloses a high-power charging and discharging test device, which includes a test table and an electric core body. The electric core body is arranged on the top of the test table. The top of the test table is provided with a containing groove. A bidirectional threaded rod is rotatably connected inside the containing groove. Two symmetrically distributed clamping plates are sleeved on the bidirectional threaded rod. The top of the test table is provided with two uniformly distributed grooves. A rack is slidingly connected inside each groove. An axle is rotatably connected inside each groove. A gear that cooperates with the rack is sleeved on each axle. A screw rod is fixedly connected to the top of the rack. A sleeve column is sleeved on the outside of the screw rod and movably connected with the sleeve column. A fixed block that cooperates with the sleeve column is fixedly connected to the top of the screw rod. A spring is fixedly connected to the top of the fixed block and arranged inside the sleeve column. Although this patent can realize charging and discharging test of the electric core, it cannot automatically adjust the position of the electric core and needs manual assistance, which is prone to electric shock due to improper operation.
