Description

Technical Field

[0001] This utility model relates to the technical field of automotive starting lead-acid battery terminal sleeves, and in particular to a novel automotive starting lead-acid battery casting and welding mold terminal sleeve structure. Background Technology

[0002] An automotive starting lead-acid battery is a type of lead-acid battery specifically designed for starting automotive engines. Its main function is to provide the electrical energy required for starting and running the automotive engine. This type of battery can provide a large amount of energy in a short period of time to meet the starting needs of the automotive engine.

[0003] In the assembly and production process of automotive starting lead-acid batteries, the busbars, welding parts, and terminals on the battery electrode group are generally produced by casting and welding. However, in order to meet the needs of different customers and different vehicle models, the structure of automotive batteries has also become diverse.

[0004] Due to the special structure of some batteries, the center position of the terminals on the battery has a certain eccentric distance from that of the general structure. If the cast-welded terminal sleeve used is not specifically designed and manufactured according to the general structure, the terminals in the cast-welded terminal group will not be aligned with the inner hole of the terminal on the battery cover. This will lead to problems such as pulling out the terminal, pressing the terminal, terminal breakage, and shell displacement during the sealing process. The battery cannot be sealed properly, which will make the battery unable to be installed and used normally. Utility Model Content

[0005] The purpose of this utility model is to provide a novel cast-welded die terminal sleeve structure for automotive starting lead-acid batteries, in order to solve the problem mentioned in the background art that the terminals in the existing cast-welded die terminal sleeves cannot be aligned with the inner holes of the battery cover terminals that are eccentric relative to the inner holes of the standard battery terminals, resulting in the battery cover sealing work not being completed smoothly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel automotive starting lead-acid battery casting and welding mold terminal sleeve structure, comprising a terminal sleeve body, wherein the top of the terminal sleeve body is provided with a mounting hole for mounting a temperature sensor, the top of the terminal sleeve body is provided with a terminal cavity, the axis of the terminal cavity is eccentrically set relative to the axis of the terminal sleeve body, a ejector pin is connected to the bottom of the terminal sleeve body, and a mounting plate is fixedly sleeved on the outer circumferential surface of the ejector pin.

[0007] Preferably, a jacket is fixedly fitted onto the outer side of the pole sleeve body, and an inlet pipe and an outlet pipe are connected to the outer side of the jacket. The inlet pipe is located below the outlet pipe. The advantage of this arrangement is that cooling water is injected into the jacket through the inlet pipe, and then the cooling water exchanges heat with the pole sleeve body and is discharged from the outlet pipe, so that the cooling water circulates to cool the pole sleeve body, thereby reducing the temperature of the pole sleeve structure during operation and ensuring that the pole sleeve structure operates stably and reliably.

[0008] Preferably, the pole sleeve body is further provided with an auxiliary cooling component. The auxiliary cooling component includes multiple elongated grooves formed at equal angles in a ring on the side of the pole sleeve body that is far from the axis of the pole cavity. The advantage of this arrangement is that it can enhance the cooling effect on the side wall of the pole sleeve body with thicker walls, thereby avoiding the poor cooling effect and overheating caused by the eccentric setting of the pole cavity on the side wall of the pole sleeve body with thicker walls. This further improves the reliability and practicality of the pole sleeve structure.

[0009] Preferably, the depth of the plurality of grooves gradually decreases from the middle to both sides. The advantage of this setting is that grooves of different depths can be set according to the distance between the side wall of the pole sleeve body and the axis of the pole cavity, so as to ensure that the temperature of the pole sleeve body is as uniform as possible and that the pole sleeve structure can work more stably.

[0010] Preferably, the auxiliary cooling component further includes two partitions symmetrically fixedly fitted onto the outer peripheral surface of the pole sleeve body. Multiple grooves are located between the two partitions. Two arc-shaped notches are symmetrically formed on the two partitions. The auxiliary cooling component also includes two sets of spacers symmetrically fixedly connected to the outer peripheral surface of the pole sleeve body. The two sets of spacers are located at the two notches. Each set of multiple spacers is arranged in an arc shape at equal angles, with gaps between adjacent spacers. The sides of the two spacers located on the leftmost and rightmost sides that are furthest apart are fixedly connected to the partitions. Multiple vertical plates are fixedly connected at equal angles in an arc shape between the adjacent sides of the two sets of partitions. The sides of the multiple vertical plates are fixedly connected to the outer side of the pole sleeve body. A through cavity is left between two adjacent vertical plates. The multiple through cavities are respectively aligned and connected to multiple gaps in each set. A water passage hole is opened at the top of the upper partition. The water inlet pipe and water outlet pipe are located on the lower side and upper side of the lower partition, respectively. The advantage of this setting is that it can increase the flow rate of cooling water through the groove, accelerate the heat exchange rate at the thicker part of the pole sleeve body, and further improve the cooling effect.

[0011] Preferably, the partition block is further provided with a spacing adjustment component for adjusting the gap between two adjacent partition blocks. The spacing adjustment component includes an air cavity opened inside the partition block, with the left and right ends of the air cavity penetrating the left and right sides of the partition block respectively. Two elastic membranes are symmetrically fixedly connected to the left and right sides of the partition block. The elastic membranes include a function to block the air cavity. The sleeve is provided with a pushing mechanism, which is used to push the two elastic membranes toward the gap or retract them from the gap. The number of mounting holes is multiple and distributed at different positions on the pole sleeve body. The advantage of this arrangement is that the flow rate of cooling water flowing through different positions of the through cavity and groove can be flexibly adjusted according to the temperature of various parts of the pole sleeve body measured by the temperature sensor. This allows for adjustment of the local cooling rate, avoids local overheating and damage to the pole sleeve body, and ensures the reliability of the pole sleeve structure.

[0012] Preferably, the pushing mechanism includes a first air hole on the inner wall of the air chamber away from the pole sleeve body, and the other end of the first air hole penetrates the side wall of the partition. The pushing mechanism also includes two sets of second air holes on the outer surface of the jacket, the two sets of second air holes are respectively connected to the first air holes on the two sets of partitions, and the two sets of second air holes are respectively connected to the external air inlet pipe. The advantage of this arrangement is that the width of the gap at different partitions can be conveniently and flexibly controlled, which improves the reliability and convenience of the pole sleeve structure.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. In this utility model, by setting the electrode cavity and electrode sleeve body, the center line of the electrode sleeve body and the center line of the electrode cavity are set eccentrically. This ensures that after the battery electrode group produced by casting and welding is inserted into the shell, the center position of the electrode is aligned with the center position of the inner hole of the terminal on the battery cover. This ensures that the electrode inserted into the electrode cavity and the inner hole of the terminal on the battery cover have a good fit and stable and reliable connection during the subsequent battery sealing process. It avoids the phenomenon of battery failure due to electrode pulling, electrode pressing, electrode breakage, shell cover displacement, etc. during the sealing process, thus avoiding the risk of battery scrap due to poor battery sealing and improving the reliability of the electrode sleeve structure.

[0015] 2. In this utility model, by setting a jacket, water inlet pipe, water outlet pipe and auxiliary cooling components, the cooling water can be divided into multiple streams and flow through multiple grooves through two partitions, two sets of partitions and multiple vertical plates. This can increase the flow rate of the cooling water through the grooves, accelerate the heat exchange rate at the thicker part of the pole sleeve body, and further improve the cooling effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please refer to Figures 1-6 The present invention relates to a novel automotive starting lead-acid battery casting and welding mold terminal sleeve structure, comprising a terminal sleeve body 1, a mounting hole 11 for mounting a temperature sensor on the top of the terminal sleeve body 1, a terminal cavity 2 on the top of the terminal sleeve body 1, the axis of the terminal cavity 2 being eccentrically set relative to the axis of the terminal sleeve body 1, a ejector pin 3 connected to the bottom of the terminal sleeve body 1, and a mounting plate 4 fixedly sleeved on the outer circumferential surface of the ejector pin 3.

[0026] An annular mounting groove 12 is opened on the outer circumference of the jacket 5. The pole sleeve structure is limited and locked into the battery box through the mounting groove 12. Then, the auxiliary sleeve structure is fixedly connected into the battery box by the mounting plate 4 and screws. At this time, the pole inserted into the eccentrically designed pole cavity 2 can be aligned with the terminal inner hole on the battery box cover, ensuring that the cover processing is completed safely and smoothly, and ensuring the safety of the pole.

[0027] refer to Figure 1 A sleeve 5 is fixedly sleeved on the outer side of the pole sleeve body 1. A water inlet pipe 51 and a water outlet pipe 52 are connected on the outer side of the sleeve 5. The water inlet pipe 51 is located below the water outlet pipe 52.

[0028] Specifically, cooling water is injected into the jacket 5 through the water inlet pipe 51. After the cooling water exchanges heat with the pole sleeve body 1, it is discharged from the water outlet pipe 52, so that the cooling water circulates to cool the pole sleeve body 1. This can reduce the temperature of the pole sleeve structure during operation and ensure that the pole sleeve structure works stably and reliably.

[0029] refer to Figure 2 , Figure 3 and Figure 6 The pole sleeve body 1 is also provided with an auxiliary cooling component 6, which includes multiple elongated grooves 61 that are opened at equal angles in a ring on the side of the pole sleeve body 1 that is far from the axis of the pole cavity 2.

[0030] Specifically, by using multiple elongated grooves 61 on the side of the pole sleeve body 1 that are far from the axis of the pole cavity 2, cooling water can penetrate deep into the side wall of the pole sleeve body 1 through the grooves 61. This enhances the cooling effect on the thicker side wall of the pole sleeve body 1, thus avoiding overheating caused by poor cooling effect on the thicker side wall of the pole sleeve body 1 due to the eccentric setting of the pole cavity 2. This further improves the reliability and practicality of the pole sleeve structure.

[0031] refer to Figure 2 and Figure 3 The depth of the multiple grooves 61 gradually decreases from the middle towards both sides.

[0032] Specifically, grooves 61 of different depths can be set according to the distance between the side wall of the pole sleeve body 1 and the axis of the pole cavity 2, so as to ensure that the temperature of the pole sleeve body 1 is as uniform as possible and that the pole sleeve structure can work more stably.

[0033] refer to Figure 4 and Figure 5 The auxiliary cooling component 6 also includes two partitions 62 symmetrically fixedly fitted onto the outer circumferential surface of the pole sleeve body 1. Multiple grooves 61 are located between the two partitions 62. Two arc-shaped notches are symmetrically formed on the two partitions 62. The auxiliary cooling component 6 also includes two sets of spacers 63 symmetrically fixedly connected to the outer circumferential surface of the pole sleeve body 1. The two sets of spacers 63 are located at the two notches. Each set of multiple spacers 63 is arranged in an arc shape at equal angles, with gaps between adjacent spacers 63. The spacer is located on the far left. The sides of the two rightmost partitions 63 that are far apart from each other are fixedly connected to the partition 62. Multiple vertical plates 64 are fixedly connected at equal angles in an arc shape between the sides of the two sets of partitions 63 that are close to each other. The sides of the multiple vertical plates 64 are fixedly connected to the outer side of the pole sleeve body 1. A through cavity is left between two adjacent vertical plates 64. The multiple through cavities are aligned and connected to each set of multiple gaps. A water passage hole 621 is opened at the top of the upper partition 62. The water inlet pipe 51 and the water outlet pipe 52 are located on the lower side and the upper side of the lower partition 62, respectively.

[0034] Specifically, the cooling water can be divided into multiple streams and flow through multiple grooves 61 by two partitions 62, two sets of partitions 63 and multiple vertical plates 64. This can increase the flow rate of the cooling water through the grooves 61, accelerate the heat exchange rate at the thicker part of the pole sleeve body 1, and further improve the cooling effect.

[0035] refer to Figures 2-6 The spacer 63 is also provided with a gap adjustment component 7 for adjusting the size of the gap between two adjacent spacers 63. The gap adjustment component 7 includes an air cavity 71 opened inside the spacer 63. The left and right ends of the air cavity 71 pass through the left and right sides of the spacer 63 respectively. Two elastic membranes 72 are symmetrically fixedly connected to the left and right sides of the spacer 63. The elastic membranes 72 include sealing the air cavity 71. The sleeve 5 is provided with a pushing mechanism 73. The pushing mechanism 73 is used to push the two elastic membranes 72 toward the gap or retract them from the gap. There are multiple mounting holes 11 and they are distributed at different positions on the pole sleeve body 1.

[0036] Specifically, by pushing the two elastic membranes 72 towards the gap or retracting them from the gap, the gap width between two adjacent partitions 63 can be reduced or increased. This allows the flow rate of cooling water flowing through different passages and grooves 61 to be flexibly adjusted according to the temperature of each part of the pole sleeve body 1 measured by the temperature sensor. This enables the adjustment of the local cooling rate, avoids local overheating and damage to the pole sleeve body 1, and ensures the reliability of the pole sleeve structure.

[0037] refer to Figure 2 , Figure 3 and Figure 6 The pushing mechanism 73 includes a first air hole 731 opened on the inner side wall of the air chamber 71 away from the pole sleeve body 1. The other end of the first air hole 731 penetrates the side wall of the partition 63. The pushing mechanism 73 also includes two sets of second air holes 732 opened on the outer side of the jacket 5. The two sets of second air holes 732 are respectively connected to the first air holes 731 on the two sets of partitions 63. The two sets of second air holes 732 are respectively connected to the external air inlet pipe.

[0038] Multiple air intake pipes are connected to multiple external air pumps, which are connected to a controller. The controller and multiple temperature sensors are connected to a central processing unit. The central processing unit receives signals from the temperature sensors and uses the controller to control the air intake volume of each air pump.

[0039] Specifically, by increasing or decreasing the air intake volume of the air intake pipe connected to different air chambers 71, the expansion amount of the elastic membrane 72 at the air chamber 71 can be controlled, thereby conveniently and flexibly controlling the width of the gap at different partitions 63, improving the reliability and convenience of the pole sleeve structure.

[0040] Working principle: When installing the terminal sleeve structure into the battery box, the terminal sleeve structure is limited and snapped into the battery box by the mounting slot 12. Then, the mounting plate 4 and screws are used to fix the auxiliary sleeve structure into the battery box. At this time, the terminal inserted into the eccentrically designed terminal cavity 2 can align with the terminal inner hole on the battery box cover, ensuring that the cover processing is completed safely and smoothly, and guaranteeing the safety of the terminal.

[0041] During operation, cooling water is injected into the jacket 5 through the inlet pipe 51. The cooling water then flows into the corresponding through cavity and groove 61 through the gap between the lower partitions 63, cooling the side wall of the pole sleeve body 1 away from the axis of the pole cavity 2. The cooling water then flows through the gap between the water hole 621 and the upper partition 63 to the side wall of the pole sleeve body 1 near the pole cavity 2, and finally flows out through the outlet pipe 52. This can uniformly and reliably cool the pole sleeve body 1, preventing the pole sleeve structure from overheating and being damaged during operation, thus improving the reliability and safety of the pole sleeve structure.

[0042] Meanwhile, temperature sensors installed in multiple mounting holes 11 monitor the temperature of various parts of the pole sleeve body 1. When the temperature at a local location is too high, the air intake of the air intake pipe at the corresponding location gap can be reduced, causing the elastic membrane 72 at the corresponding location gap to retract. This increases the width of the gap, thereby increasing the amount of cooling water flowing through it, thus improving the cooling speed and effect on the overheated location, and further improving the reliability and safety of the pole sleeve structure.

[0043] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
