[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0019] In the present invention, unless otherwise specified or limited, the terms "assemble," "connect," and "connect" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection; direct connection, connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0020] The following description of the embodiments of the present invention is provided in conjunction with the accompanying drawings to further describe the specific embodiments of the present invention so that the technical solutions and beneficial effects of the present invention will be more clearly understood. The following description of the embodiments with reference to the accompanying drawings is illustrative and intended to explain the present invention, but is not to be construed as limiting the present invention.

[0021] The preferred embodiment provided by the present invention is as follows: Figures 1 to 3 As shown, a secondary battery backup cell structure includes a housing 1, a cover plate 2, a first cell 3, a second cell 4 and a conductive connector assembly 6;

[0022] The housing 1 has a cavity 11, a partition is provided in the cavity 11 to divide the cavity 11 into a first cavity 12 and a second cavity 13, the first battery cell 3 is installed in the first cavity 12, the second battery cell 4 is installed in the second cavity 13, and the cover plate 2 is installed at the end of the housing 1 to encapsulate the first battery cell 3 and the second battery cell 4 in the cavity 11;

[0023] The conductive connector assembly 6 includes a pole assembly 7, a first conductive plate 61, a second conductive plate 62, and a connecting piece 8; the head ends of the first conductive plate 61 and the second conductive plate 62 are both connected to the connecting piece 8, and the ends are respectively connected to the first battery cell 3 and the second battery cell 4, and the first conductive plate 61 and the second conductive plate 62 are respectively arranged on both sides of the connecting piece 8, and the head ends of the first conductive plate 61 and the second conductive plate 62 are separated to limit the contact between the first conductive plate 61 and the second conductive plate 62; in this embodiment, the first conductive plate 61 and the second conductive plate 62 are collectively referred to as conductive plates, unless otherwise specified and described separately.

[0024] The terminal assembly 7 includes a terminal cover 71 and a conductive core 72. The terminal cover 71 is fixed to the cover plate 2. The terminal cover 71 has an access hole 73 that communicates with the cavity 11. The conductive core 72 is connected to the access hole 73. The conductive core 72 extends vertically downward from the conductive core 72 to form a metal connector 9. The conductive core 72 rotates about the access hole 73 so that the conductive core 72 is connected to the first conductive plate 61 and the second conductive plate 62 through the metal connector 9. The metal connector 9 includes a spring 91 and a contact pin 92. The bottom of the conductive core 72 is provided with a recessed hole 76 located at the edge of the conductive core to better connect with the first and second conductive plates. The head end of the spring 91 is fixed to the recessed hole 76, and the tail end is fixed to the contact pin 92. The contact pin 92 is elastic due to the action of the spring 91. The connection end of the contact pin 92 to the conductive plate has a curvature, so that when the contact pin 92 rotates, it can adapt to the height difference and smoothly connect with each conductive plate. The length of the spring 91 should be adapted to the depth of the recessed hole 76 so that the conductive core 72 is retained in the recessed hole 76 and a portion of the conductive core 72 continues to be exposed outside the recessed hole 76 .

[0025] The upper end surface of the conductive core column 72 is provided with a cross groove 74. The conductive head is connected to the conductive core column to introduce current. The conductive head is a metal column connected to the battery. The connecting end of the conductive head and the conductive core column 72 is also cross-shaped, so that the conductive head and the conductive core column 72 are compactly connected, which facilitates the simultaneous rotation of the conductive head and the conductive core column 72.

[0026] A barrier rib 81 is provided at the center of the connector 8. The top ends of the first and second conductive plates 61, 62 are connected to either side of the barrier rib 81, preventing the first and second conductive plates 61, 62 from contacting each other. Covers 82 extend from the top of the barrier rib 81, forming slots 83 with the top surface of the connector 8. The cover 82 should be small to avoid obstructing the metal connector 9 from connecting to the conductive plates.

[0027] The first conductive plate 61 and the second conductive plate 62 are both provided with a joint 63 at their head ends, and a protrusion 64 extends from the inner side of the joint 63; the connecting piece 8 is a cylinder, and the joint 63 is semicircular so that the joints 63 of the first conductive plate 61 and the second conductive plate 62 can be compactly connected on both sides of the connecting piece 8; the joint 63 has a recess 65, and the protrusion 64 is located in the recess 65, and the connecting piece 8 is embedded in the recess 65. The connecting piece 8 is provided with a recess 84, and the protrusion 64 is connected to the recess 84 to confine the first conductive plate 61 and the second conductive plate 62 to the connecting piece 8.

[0028] A clamping block 75 extends from the access hole 73 , and a groove 66 is provided on the side of the conductive core column 72 . The clamping block 75 is connected to the groove 66 to restrict the conductive core column 72 from remaining in the access hole 73 without hindering the conductive core column 72 from rotating in the access hole 73 .

[0029] The operating principle is that the conductive core column can rotate within the access hole, with the first conductive plate connected to the first battery cell and the second conductive plate connected to the second battery cell. When the first battery cell is in use, the conductive core column rotates to connect the contact column to the first conductive plate, allowing the first battery cell to be used. When the first battery cell runs out of power, the second battery cell can be used as a backup power source by rotating the conductive core column to connect the contact column to the second conductive plate, allowing the second battery cell to be used. In this embodiment, the conductive connector assembly is divided into a positive conductive connector assembly and a negative conductive connector assembly. The positive and negative conductive connector assemblies have the same structure, and the conductive core columns of both assemblies should rotate simultaneously to ensure connection to the same battery cell.

The schematic expressions of the above terms in this specification do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any appropriate manner in any one or more embodiments or examples.

[0031] Through the description of the above structure and principle, technical personnel in the relevant technical field should understand that the present invention is not limited to the above specific implementation methods, and improvements and substitutions based on the present invention using the well-known technology in the field all fall within the scope of protection of the present invention and should be defined by the claims.
