Abstract

The invention discloses a lithium core battery pack convenient to replace. The lithium core battery pack includes an outer casing and an inner casing. The inner casing is movably disposed in the outercasing, the surfaces of the two sides of the inner casing are provided with lithium core mounting grooves for placing lithium core bodies, an upper electrical contact and a lower electrical contact are fixed at the upper end and the lower end of each lithium core mounting groove respectively, the end of the outer casing is rotatably connected with a clamping plate, one end of the clamping plate is movably clamped with the inner casing, and the bottom of an inner chamber of the outer casing is fixedly connected with a push plate through a first spring. According to the lithium core battery pack, through mutual matching of a sliding rail and a sliding groove, the inner casing is conveniently pushed into the outer casing, a clamping block at the end of the clamping plate can be pushed automatically into the clamping groove of the inner casing under the action of a second spring, to clamp the inner casing; by pressing of the clamping plate, the clamping block is separated from the clamping groove; at the same time, under the action of the first spring, the push plate is driven to automatically push the inner casing out, and the inner casing is taken out conveniently through a handle to replace the lithium core bodies.

Example Embodiment

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] like Figure 1-5 As shown, a convenient replacement lithium cell battery pack includes an outer casing 1 and an inner casing 12, the inner casing 12 is movably arranged inside the outer casing 1, and both sides of the inner casing 12 are provided with There is a lithium battery cell installation groove 8 for placing the lithium battery cell body 14. The upper and lower ends of the lithium battery cell installation groove 8 are respectively fixed with an upper electrical contact piece 9 and a lower electrical contact piece 7, and the outer end of the inner casing 12 is in turn A terminal bolt 6, a handle 10 and a control switch 11 are installed, and the end of the outer shell 1 is rotatably connected with a clamping plate 2, and one end of the clamping plate 2 is movably engaged with the inner shell 12, and the outer shell 1 The bottom of the inner cavity is fixedly connected with a push plate 4 through a first spring 3 .
[0023] Both sides of the inner casing 12 are integrally provided with slide rails 13, and the inner cavity side wall of the outer casing 1 is provided with a slide groove 15 matched with the slide rails 13, and the slide rails 13 can be used to facilitate The inner housing 12 is pushed into the outer housing 1, and at the same time, the slide rail 13 cooperates with the chute 15 to prevent the inner housing 12 from shaking and improve the stability.
[0024] The upper electrical contact piece 9 and the lower electrical contact piece 7 are closely attached to the positive and negative poles of the lithium cell body 14 respectively, and the upper electrical contact piece 9 and the lower electrical contact piece 7 are connected with a terminal bolt 6 and a control switch 11 through a wire. , the upper electrical contact piece 9 and the lower electrical contact piece 7 are both pressed and formed by copper sheets, and have good electrical conductivity. The lithium battery body 14 is clamped in the lithium battery installation groove 8 through the upper electrical contact piece 9 and the lower electrical contact piece 7, Easy to assemble and disassemble.
[0025] One side of the inner housing 12 is provided with a card slot 5, and one end of the inner side of the card plate 2 is integrally provided with a card block 16, and the card block 16 is engaged with the card slot 5, and the card block 16 is Wedge shape, when the inner housing 12 is pushed into the outer housing 1, the inner housing 12 pushes up the clamping plate 2 along the hypotenuse on the clamping block 16 until the clamping block 16 enters the slot 5, the second spring 17 Under the push of the inner casing 12, the inner housing 12 can be fixed.
[0026] The end of the clamp 2 protruding from the outer shell 1 is provided with an anti-slip pattern, which is convenient for pressing the clamp 2 and avoiding slipping. The second spring 17, through the second spring 17, the block 16 at the end of the clamping plate 2 can be automatically pushed into the slot 5 on the inner housing 12, and the inner housing 12 is automatically clamped.
[0027] The length of the push plate 4 is the same as that of the inner housing 1 , and two first springs 3 are provided and located at both ends of the push plate 4 .
[0028] The depth of the lithium battery cell installation groove 8 is the same as the diameter of the lithium battery cell body 14. When the inner casing 12 is pushed into the outer casing 1, the lithium battery cell body 14 can be stably kept in the lithium battery cell installation groove 8 by using the outer casing 1 , to prevent the lithium battery core body 14 from coming out.
[0029] Specifically, when in use, the lithium battery core bodies 14 are respectively installed in the lithium battery cell installation slots 8. After the installation is completed, the inner housing 12 is pushed into the outer housing 1 along the slide rail 13. When the inner housing 12 is pushed into the outer housing When the body 1 is in contact with the clamping block 16, the clamping plate 2 will be pushed up along the hypotenuse on the clamping block 16 until the clamping block 16 enters the clamping groove 5, under the action of the second spring 17, the clamping plate 2 can be pushed up. The block 16 at the end of the plate 2 is automatically pushed into the slot 5 on the inner casing 12, automatically clamps the inner casing 12, presses the clip 2, and the block 16 comes out of the slot 5, and at the same time, Under the action of the first spring 3, the push plate 4 is pushed to automatically push out the inner casing 12, and the inner casing 12 is conveniently taken out through the handle 10 to replace the lithium battery cell body 14. Lithium cell bodies 14 are used in series or in parallel through wires, which can be connected according to the conditions of use. Connect the electrical equipment to the terminal bolt 6 to complete the connection, and use the control switch 11 to realize the opening and closing of the circuit, which is easy to operate.
