Description

Technical Field

[0001] This utility model relates to the field of lithium battery negative electrode technology, and in particular to an impedance automotive lithium battery negative electrode. Background Technology

[0002] With the development of modern electronic technology, miniaturized devices are becoming increasingly common, placing high demands on power supplies. Electrochemical devices have thus entered a stage of large-scale practical application. Initially, electrochemical devices were mainly used in small personal electronic devices such as mobile phones and laptops. However, with technological advancements and the expansion of their applications, lithium batteries have begun to be used in motorcycles, automobiles, power tools, and electric vehicles.

[0003] The impedance of the negative terminal of a car lithium battery refers to the response characteristics of the battery's negative terminal to an external circuit in an AC circuit. It reflects the combined effect of the internal resistance, capacitance, and inductance of the battery's negative terminal. When installing a car battery's negative terminal, it needs to be connected to the negative cable terminal with bolts. However, the negative cable terminal usually has a certain degree of flexibility for easy installation. This can cause the cable terminal to deviate when connected to the negative terminal body, making it impossible to align the cable terminal with the screw holes on the negative terminal body's connector, thus increasing the inconvenience of installation. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an impedance-type negative terminal post for automotive lithium batteries, which aims to improve the problem that the inability to perform preliminary positioning of cable terminals affects the fixed connection and installation of cable terminals and negative terminal post body.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An impedance automotive lithium battery negative terminal includes a connector, a negative terminal body is installed at the center of the top surface of the connector, a cable terminal is sleeved on the outside of the negative terminal body, an installation groove is provided on the top surface of the connector, a positioning component is provided inside the installation groove, the bottom surface of the cable terminal is fixedly connected to the mounting base, and slots are provided on both sides of the mounting base.

[0007] Preferably, the positioning assembly includes a push plate, inserts, connecting rods, telescopic rods, and a telescopic spring. The two push plates are symmetrically arranged inside the mounting groove. The two inserts are respectively fixedly installed on one side of the push plate. The two telescopic rods are fixedly installed on one side of the push plate. The connecting rod is fixedly installed at the center of one side of the push plate. The telescopic spring is arranged inside the telescopic rod.

[0008] Preferably, a bearing is fixedly connected to one end of each of the two connecting rods, a pull rod is fixedly connected to one side of each of the two bearings, and a lever is fixedly connected to the top of the pull rod.

[0009] Preferably, the top surface of the connecting seat has two movable slots, and the actuating rod is placed inside the movable slots.

[0010] Preferably, the top ends of the two levers are fixedly connected to a paddle.

[0011] Preferably, the top surface of the connector has two clips and slots, and the clips and slots are connected to the movable slot.

[0012] Preferably, the top surface of the mounting base has a plurality of second screw holes.

[0013] Preferably, the mounting groove has a first screw hole inside, and a mounting bolt passes through the first screw hole and the second screw hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting a positioning component, allows the cable terminal mounting base to be installed into the mounting groove during cable terminal installation. The extension force of the telescopic spring can push the push plate, which pushes the insert into the slot, thereby positioning the mounting base inside the mounting groove. This allows the cable terminal to be positioned so that the first screw hole automatically aligns with the second screw hole, and the cable terminal will not deviate, increasing the convenience of installation.

[0016] 2. This utility model, by setting a bearing and a negative terminal body, allows the lever to be rotated in the direction of the slot when the lever is pulled, so that the lever can be rotated inside the bearing and thus the lever can be locked into the slot. This can limit the position of the push plate and the insert, preventing them from obstructing the installation of the mounting base into the mounting slot. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides: an impedance automotive lithium battery negative terminal post, including a connector 1, a negative terminal post body 8 installed at the center of the top surface of the connector 1, a cable terminal 2 sleeved on the outside of the negative terminal post body 8, an installation groove 9 opened on the top surface of the connector 1, a positioning component provided inside the installation groove 9, an installation seat 6 fixedly connected to the bottom surface of the cable terminal 2, and slots 20 opened on both sides of the installation seat 6.

[0026] Specifically, this device can be powered on by connecting the cable terminal 2 to the negative terminal body 8. The negative terminal body 8 used in this device is a commonly used negative terminal in existing devices, and its connection method with the cable terminal 2 is also quite common. Therefore, its specific structure and principle will not be described in detail here.

[0027] Reference Figure 3 and Figure 4 The positioning assembly includes a push plate 11, a insert 12, a connecting rod 13, a telescopic rod 14, and a telescopic spring 17. The two push plates 11 are symmetrically arranged inside the mounting groove 9. The two inserts 12 are respectively fixedly installed on one side of the push plate 11. The two telescopic rods 14 are fixedly installed on one side of the push plate 11. The connecting rod 13 is fixedly installed at the center of one side of the push plate 11. The telescopic spring 17 is arranged inside the telescopic rod 14.

[0028] Specifically, the telescopic rod 14 is divided into an inner rod and an outer rod, and the two ends of the telescopic spring 17 are connected to the inner rod and the outer rod of the telescopic rod 14. Therefore, in the initial state, the telescopic spring 17 can push the inner rod outward by the opposite force. When the telescopic rod 14 retracts, its inner rod will also squeeze the telescopic spring 17 inward. The size and dimensions of the insert 12 correspond to the size and dimensions of the slot 20. The size and dimensions of the mounting base 6 also correspond to the size and dimensions of the mounting groove 9. Therefore, when the mounting base 6 is inserted into the inside of the mounting groove 9, the insert 12 can be inserted into the inside of the slot 20. At this time, the mounting base 6 can be fixedly installed inside the mounting groove 9, thereby fixing the position of the mounting base 6 and the cable terminal 2. This makes it easier for the staff to position the cable terminal 2 and prevent it from shifting during the installation process, which would affect the fixation of the cable terminal 2.

[0029] Reference Figure 2 and Figure 3 One end of each of the two connecting rods 13 is fixedly connected to a bearing 15, and one side of each of the two bearings 15 is fixedly connected to a pull rod 16. The top of the pull rod 16 is fixedly connected to a toggle rod 19. The top surface of the connecting seat 1 has two moving grooves 3, and the toggle rod 19 is placed inside the moving grooves 3.

[0030] Specifically, one end of the pull rod 16 is connected to the rotating end of the bearing 15, so that the pull rod 16 can be deflected to one side, and the pull rod 16 can rotate inside the bearing 15. The top of the actuating rod 19 extends into the interior of the moving groove 3 and extends upward a certain distance.

[0031] Reference Figure 3 Two levers 19 are fixedly connected to the top of a lever 7. The top surface of the connecting seat 1 has two clips and slots 4, and the clips and slots 4 are connected to the moving slot 3.

[0032] Specifically, the lever 7 is fixedly connected to the extension end of the lever 19. The lever 7 allows the operator to easily pull the lever 19. When the lever 19 is pulled, the connecting rod 13 can be moved. The connecting rod 13 can then move the push plate 11 and the insert 12 inside the mounting slot 9. After the insert 12 has moved a certain distance, the lever 7 can be deflected to one side. The lever 7 can drive the lever 7 rod to deflect, deflecting the lever 19 into the slot 4. This allows the lever 19 to be positioned. Once the position of the lever 19 is fixed, the position of the insert 12 can be positioned, making it convenient for the operator to insert the mounting base 6 into the mounting slot 9. This prevents the position of the insert 12 from affecting the insertion of the mounting base 6 into the mounting slot 9. The size of the moving slot 3 is larger than the size of the pull rod 16, thus ensuring the space for the lever 19 to drive the pull rod 16 to deflect, thereby ensuring the normal deflection of the lever 19.

[0033] Reference Figure 2 and Figure 5 The top surface of the mounting base 6 is provided with multiple second screw holes 18, the inside of the mounting groove 9 is provided with a first screw hole 10, and a mounting bolt 5 passes through the first screw hole 10 and the second screw hole 18.

[0034] Specifically, when the mounting base 6 is inserted into the mounting slot 9, the position of the first screw hole 10 is aligned with the position of the second screw hole 18. At this time, it is convenient for the staff to pass the mounting bolt 5 through the first screw hole 10 and the second screw hole 18, which greatly facilitates the fixed connection between the cable terminal 2 and the negative terminal body 8.

[0035] Working principle: When using this device, place it in the designated position and move the two levers 7 to both sides. The levers 7 pull the pull rod 16 via the lever 19, which in turn pulls the connecting rod 13. The connecting rod 13 pulls the push plate 11 to move to both sides, which in turn pulls the insert 12 to move to one side. The levers 7 are then deflected to one side, causing the lever 7 to drive the pull rod 16 to deflect inside the bearing 15 via the lever 19. This deflects the lever 19 into the slot 4, thus limiting its position and positioning the insert 12. At this point, the mounting base 6 can be inserted into the mounting groove 9, and the levers 7 can be moved back. The telescopic spring 17 can push the inner rod of the telescopic rod 14 outward through the reverse force, and the telescopic rod 14 can push the push plate 11 to reset. The push plate 11 can push the insert 12 into the slot 20, thereby positioning the mounting base 6 inside the mounting groove 9. This can prevent the cable terminal 2 from deviating. After the mounting base 6 is installed into the mounting groove 9, the first screw hole 10 can be aligned with the second screw hole 18. At this time, the mounting bolt 5 can be passed through the first screw hole 10 and the second screw hole 18 to further fix and connect the cable terminal 2 to the negative terminal body 8. This device can facilitate the positioning of the cable terminal 2 during use and also facilitate the installation of the cable terminal 2 by the staff.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
