Description

Technical Field

[0001] This utility model relates to the field of starting power technology, and in particular to a motorcycle starting battery. Background Technology

[0002] A motorcycle starter battery is a device that provides electrical energy to start a motorcycle engine. Its main function is to provide enough current to the starter motor at the moment the motorcycle starts, so that the motor can drive the engine crankshaft to rotate, thereby starting the engine.

[0003] Chinese patent document CN212991141U discloses a motorcycle starting battery, which includes a battery casing, comprising a casing body and a casing cover, and a battery pack disposed within the casing body. The casing cover has a positive terminal and a negative terminal, which are respectively connected to the positive and negative terminals of the battery pack. It is evident that the positive and negative terminals of this motorcycle starting battery are partially encased in the plastic casing cover, i.e., the assembly of the positive and negative terminals with the plastic casing cover is achieved using an injection molding process: a mold with terminals is pre-designed, and molten plastic is injected into it, so that the terminals are partially encased within the plastic casing cover, thereby achieving the connection. This injection molding assembly method requires the manufacture of a special mold with terminals, and the design and manufacturing cost of such a special mold is high, thus increasing the production cost of the motorcycle starting battery. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a motorcycle starting battery in which the positive and negative quick-connect terminals can be installed simply by inserting them into the corresponding positions on the top cover, thereby reducing the injection molding cost of the top cover and thus reducing the production cost of the motorcycle starting battery.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A motorcycle starting battery includes a lower casing, a battery pack fixed inside the lower casing, and a top cover fixed to the top of the lower casing. The top cover has a positive quick-connect terminal and a negative quick-connect terminal. Both the positive and negative quick-connect terminals include an integrally formed first insert plate, a wiring body, an L-shaped limiting plate, and a second insert plate connected in sequence. One side of the top cover has a socket for inserting the second insert plate. The top cover has limiting shoulders on both sides of the socket. The L-shaped limiting plate abuts against the outer wall of the top cover and is located between the limiting shoulders. The top of the top cover has a first slot for inserting the first insert plate.

[0007] In some embodiments, a stop block is provided at the upper end of the lower shell corresponding to the position of the L-shaped limiting plate. The stop block is used to insert between the limiting shoulders and abut against the outside of the L-shaped limiting plate.

[0008] In some embodiments, the wiring body is provided with a first wiring hole and a second wiring hole, and the plane where the first wiring hole is located intersects with the plane where the second wiring hole is located.

[0009] Compared with the prior art, this utility model achieves at least the following beneficial effects:

[0010] Both the positive and negative quick-connect terminals are designed as independent structures. When assembling the motorcycle starting battery, the positive and negative quick-connect terminals only need to be inserted into the corresponding positions on the top cover to complete the installation. Specifically, the second insert plate of the positive or negative quick-connect terminal is aligned with the insertion port of the top cover, while the first insert plate is inserted into the first slot of the top cover. The L-shaped limiting plate abuts against the outer wall of the top cover to limit the insertion and indicate to the operator that the insertion is complete. The limiting shoulder can limit the L-shaped limiting plate to the left and right, thereby achieving a reliable connection between the positive or negative quick-connect terminal and the top cover.

[0020] The present invention will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present application may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of this application more complete and to fully convey the concept of the present application to those skilled in the art.

[0021] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1-7 As shown in the embodiment of this application, a motorcycle starting battery includes a lower shell 1, a battery pack 2 fixed inside the lower shell 1, and an upper cover 3 fixed to the top of the lower shell 1.

[0023] The upper cover 3 is provided with a positive quick-connect terminal 4 and a negative quick-connect terminal 5. Both the positive quick-connect terminal 4 and the negative quick-connect terminal 5 include a first plug plate 100, a wiring body 200, an L-shaped limiting plate 300 and a second plug plate 400 that are integrally set and connected in sequence. One side of the upper cover 3 is provided with a socket 31 for the second plug plate 400 to be inserted. The upper cover 3 is provided with limiting shoulders 32 on both sides of the socket 31. The L-shaped limiting plate 300 abuts against the outer side wall of the upper cover 3 and is located between the limiting shoulders 32. The top of the upper cover 3 is provided with a first slot 33 for the first plug plate 100 to be inserted. By designing both the positive quick-connect terminal 4 and the negative quick-connect terminal 5 as independent structures, during the assembly of the motorcycle starting battery, the positive quick-connect terminal 4 and the negative quick-connect terminal 5 only need to be inserted into the corresponding positions of the top cover 3 to complete the installation. Specifically, the second insert plate 400 of the positive quick-connect terminal 4 or the negative quick-connect terminal 5 is aligned and inserted into the socket 31, while the first insert plate 100 is inserted into the first slot 33. The L-shaped limiting plate 300 abuts against the outer wall of the top cover 3 to limit the insertion and indicate that the insertion is complete. The limiting shoulder 32 can limit the L-shaped limiting plate 300 to the left and right, thereby achieving a reliable connection between the positive quick-connect terminal 4 or the negative quick-connect terminal 5 and the top cover 3.

[0024] Specifically, a stop block 11 is provided at the upper end of the lower shell 1 corresponding to the position of the L-shaped limiting plate 300. When the upper cover 3 and the lower shell 1 are assembled and fixed, the stop block 11 of the lower shell 1 can be inserted between the limiting shoulders 32 and abut against the outside of the L-shaped limiting plate 300, thereby further improving the reliability of the connection between the positive quick-connect terminal 4 or the negative quick-connect terminal 5 and the upper cover 3.

[0025] Furthermore, the wiring body 200 is provided with a first wiring hole 201 and a second wiring hole 202. The plane where the first wiring hole 201 is located intersects with the plane where the second wiring hole 202 is located. The first wiring hole 201 and the second wiring hole 202 are used to screw in bolts or screws when wiring.

[0026] The battery pack 2 includes multiple sodium-ion cylindrical cells 21, which are divided into four battery groups. The sodium-ion cylindrical cells 21 in each battery group are connected in parallel, and the four battery groups are connected in series. A cell support 6 is fixed inside the lower shell 1. Multiple cylindrical upright slots 61 and inverted slots 62 are arranged on the cell support 6. The upright slots 61 and inverted slots 62 are used to hold the sodium-ion cylindrical cells 21 upright and inverted, respectively. The bottom end of the upright slot 61 is set as an opening end 7 for inserting the sodium-ion cylindrical cells 21, and the top end is provided with a foolproof hole 8 that matches the positive electrode cap of the sodium-ion cylindrical cells 21. The top end of the inverted slot 62 is set as an opening end 7 for inserting the sodium-ion cylindrical cells 21, and the bottom end is provided with a foolproof hole 8 that matches the positive electrode cap of the sodium-ion cylindrical cells 21. It should be noted that when assembling the sodium-ion cylindrical cell 21 and the cell support 6, the sodium-ion cylindrical cell 21 can be directly inserted into the upright slot 61 and the inverted slot 62. The upright slot 61 and the inverted slot 62 are designed to allow the sodium-ion cylindrical cell 21 to be installed upright or inverted in a certain arrangement order, which facilitates the connection of four battery groups end to end to achieve series connection. The design of the anti-fool hole 8 can effectively prevent the operator from installing the sodium-ion cylindrical cell 21 backwards, making it convenient for the operator to quickly identify whether the sodium-ion cylindrical cell 21 is installed backwards.

[0027] Specifically, the cell support 6 is provided with several vertical insertion holes 63; the bottom surface of the lower shell 1 is provided with right-angle plates 12 at the four corners, and the bottom surface of the lower shell 1 is also provided with several positioning posts 13 at intervals for insertion into the insertion holes 63. When assembling the cell support 6 and the lower shell 1, the right-angle plates 12 can provide coarse positioning for the four corners of the cell support 6, while the insertion of the positioning posts 13 into the insertion holes 63 can achieve a reliable connection between the cell support 6 and the lower shell 1.

[0028] Connecting nickel plates 9 are provided between the positive quick-connect terminal 4 and the positive terminal of the battery pack 2, and between the negative quick-connect terminal 5 and the negative terminal of the battery pack 2. The connecting nickel plates 9 include a first welding piece 91, an L-shaped connecting piece 92, and a second welding piece 93 integrally formed and connected in sequence. The second welding piece 93 is parallel to the first welding piece 91. The first welding piece 91 is welded to the positive or negative terminal of the battery pack 2, and the second welding piece 93 is welded to the second insertion plate 400. Since the L-shaped connecting piece 92 is connected between the first welding piece 91 and the second welding piece 93, when the second insertion plate 400 of the positive quick-connect terminal 4 or the negative quick-connect terminal 5 is aligned and inserted into the socket 31, the vertical piece of the L-shaped connecting piece 92 can guide the second insertion plate 400. It should be noted that by designing the connecting nickel sheet 9, laser welding can be used to directly weld the connecting nickel sheet 9 between the positive quick-connect terminal 4 and the battery pack 2, and between the negative quick-connect terminal 5 and the battery pack 2. Compared with the existing technology that uses solder wire welding and wire connection, this can greatly reduce material costs and improve production efficiency.

[0029] Specifically, the L-shaped connecting piece 92 is provided with multiple positioning holes 921; the battery cell bracket 6 is provided with multiple positioning protrusions 64 that match the positioning holes 921. By cooperating with the positioning holes 921 and the positioning protrusions 64, the L-shaped connecting piece 92 can be pressed onto the battery cell bracket 6, and then the welding of the connecting nickel sheet 9 can be carried out, which can improve the reliability of the connection.

[0030] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
