Description

Technical Field

[0001] The present invention relates to the technical field of automobile battery accessories, and more particularly to an automobile battery separator. Background Art

[0002] The automotive battery mainly includes a shell, an upper end cover, a partition and a battery. The shell and the upper end cover enclose a main chamber, and multiple partitions are distributed in the main chamber to separate multiple sub-chambers. Multiple batteries are installed in each sub-chamber. Multiple batteries are connected in series and connected to external power distribution equipment through positive and negative poles.

[0003] Specifically, a single battery consists of positive and negative plates, separators and electrolyte. The positive and negative plates are immersed in the electrolyte, and the separators separate the positive and negative plates, forming an electrochemical reaction as a whole to generate electrical energy.

[0004] In the related art, the separator structure that separates each battery is relatively simple, and is generally only set as a flat plate structure, and its two vertical sides are in direct contact with the battery. The problem with the related art is that a lot of heat energy is generated during the battery charging and discharging process, and the heat energy is not easy to dissipate due to the direct contact between the separator and the battery; in addition, during the long-term use of the battery, it may bulge or be affected by external factors and exert pressure on the separator. Since the separator in the related art is difficult to buffer the pressure, it is not conducive to keeping the battery stable.

[0005] In summary, how to improve the heat dissipation capacity of the battery and how to buffer the pressure exerted on the partition by battery bulging or external force are problems that need to be solved urgently by those skilled in the art. Summary of the invention

[0006] In view of this, an object of the present invention is to provide an automotive battery separator that is effective.

[0046] Please refer to Figures 1 to 6 ,in Figure 1 It is a schematic diagram of the cross-sectional structure of a car battery from top view; Figure 2 for Figure 1 A schematic diagram of the structure enlargement at the center A; Figure 3 Another schematic diagram of a top-down cross-sectional structure of a car battery; Figure 4 It is a schematic diagram of the front cross-sectional structure of an automobile battery; Figure 5 for Figure 3 A schematic diagram of the structure enlarged at B in the middle; Figure 6 for Figure 4 A magnified schematic diagram of the structure at C in the middle.

[0047] The following is a more detailed introduction to an automotive battery separator provided by the present invention in conjunction with the accompanying drawings and specific embodiments.

[0048] An automobile battery separator provided by the present invention includes a plate body 1 arranged in an automobile battery shell. A plurality of plate bodies 1 can be provided as needed. The plurality of plate bodies 1 are fixed in the shell to separate a placement space for a plurality of batteries. A single battery is placed in the placement space. By connecting a plurality of batteries in series and extending the positive and negative poles of the automobile battery to one end outside the shell and connecting them to a power distribution device, the charging and discharging of the automobile battery can be achieved.

[0049] Reference Figure 1 A plurality of convex ribs 4 are arranged on both sides of the plate body 1 facing the placement space, specifically having the following structure, each convex rib 4 includes two relatively distributed rib plates, one end of the two rib plates is integrally connected to the plate body 1, and the other end extends horizontally and is close to each other; the convex rib 4 also includes a side plate connecting the two rib plates away from the plate body 1, and two end plates covering the upper and lower ends of the two rib plates, finally forming a convex rib 4 structure protruding outward and hollow on the surface of the plate body 1.

[0050] Furthermore, the multiple ribs 4 on the same side of the plate body 1 are arranged to be spaced and parallel to each other, and each rib 4 extends in the vertical plane along the height direction of the plate body 1 as a whole. In order to save the space occupied by the partition as a whole, the ribs 4 on both sides of the plate body 1 are preferably arranged in a staggered distribution so that the concave part on one side of the plate body 1 matches the convex part on the other side. The air flow channel 5 between two adjacent ribs 4 on the same side of the plate body 1 can dissipate the heat generated during the battery charging and discharging process through the air flow channel 5, thereby improving the overall heat dissipation efficiency of the battery.

[0051] Furthermore, a sealing groove 6 is formed inside the plate body 1, and the sealing groove 6 is formed between the concave part and the convex part of the plate body 1. By filling the sealing groove 6 with a cooling fluid, heat exchange can be achieved with the battery during operation, further improving the heat dissipation efficiency of the battery. The cooling fluid can be a conventional coolant or other materials, which are not limited here.

[0052] Reference Figure 1 , Figure 2 and Figure 3A buffer unit 2 is arranged outside a single convex rib 4, and the buffer unit 2 is movably connected to the convex rib 4. Specifically, the movable direction of the buffer unit 2 is perpendicular to the plane where the plate body 1 is located. Based on the convex rib 4, the buffer unit 2 further protrudes away from the plate body 1. When a single battery is placed in the placement space, the two side surfaces of the battery are respectively in contact with the buffer unit 2 on the side close to the two plates 1.

[0053] The buffer unit 2 includes a buffer plate 21 adapted to the convex rib 4, and the two are spaced apart. The buffer plate 21 has a mating surface and a pressure surface, the mating surface faces the convex rib 4, and the pressure surface is used to contact the battery in the placement space. A buffer connector 22 is arranged on the side of the buffer plate 21 facing the convex rib 4. The buffer connector 22 is movably arranged on the convex rib 4 and abuts against the buffer plate 21. A mounting groove is formed on the convex rib 4. One end of the mounting groove passes through the surface of the convex rib 4 facing the buffer plate 21, and the other end is connected to the sealing groove 6. The buffer connector 22 is specifically arranged in the mounting groove. When the above structure is adopted, the pressure change in the placement space is transmitted to the buffer connector 22 through the buffer plate 21; the pressure change in the sealing groove 6 is transmitted to the buffer plate 21 through the buffer connector 22. The setting of the buffer unit 2 can make the external force of a single battery acting on the partition act on the cooling fluid in the sealing groove 6 through the buffer unit 2, thereby dissolving the external force, ensuring the stability of the battery, and extending the service life.

[0054] In order to enable the cooling fluid to better exchange heat with the battery in the placement space and ensure the heat dissipation efficiency, further, an opening is provided on the rib 4, and the opening connects the sealing groove 6 with the space between the rib 4 and the buffer plate 21, so that the cooling fluid can flow through the opening to between the buffer plate 21 and the rib 4, thereby ensuring the heat dissipation efficiency. A sealing frame 23 is also provided on the side of the buffer plate 21 facing the rib 4, and the shape of the sealing frame 23 matches the shape of the opening, that is, the outer surface of the sealing frame 23 fits the inner wall of the opening, and when the buffer plate 21 moves relative to the rib 4 under pressure, the sealing frame 23 moves synchronously, so that the rib 4 and the buffer plate 21 maintain a sealed connection to prevent leakage of the cooling fluid.

[0055] The above-mentioned buffer connector 22 is specifically a steel ball set in the installation groove, and the installation groove is configured as an axial hole structure compatible with steel. In order to ensure the stability of the buffer plate 21 during movement, the buffer connector 22 is preferably provided in four groups, and the four groups of buffer connectors 22 correspond to the four corners of the buffer plate 21. Specifically, the two groups of buffer connectors 22 on the same side of the convex rib 4 and the two groups of buffer connectors 22 on the other side are symmetrical about the midline of the convex rib 4. Each group of buffer connectors 22 specifically has two steel balls. Correspondingly, the number of installation grooves opened on the convex rib 4 is eight, and a steel ball is installed in each installation groove. It can be understood that the buffer connector 22 can also be set in two or six groups, which is not limited here.

[0056] In addition, a groove is reserved on the side of the convex rib 4 facing the opening, and the groove is arranged in a ring shape around the outer periphery of the opening. A sealing ring 7 is installed in the groove. When the buffer unit 2 is matched with the convex rib 4, the inner surface of the sealing ring 7 is in full contact with the outer surface of the sealing frame 23 to ensure the sealing effect and avoid leakage of the cooling fluid. The sealing ring 7 can be made of rubber material.

[0057] Reference Figure 4 , Figure 5 and Figure 6 , a conductive unit 3 is also arranged on the plate body 1, and the conductive unit 3 is arranged at the upper end of the plate body 1. When a single battery is placed in the placement space, the conductive unit 3 can connect the positive and negative electrodes of the two batteries located on both sides of the plate body 1, and this structure is used to realize multiple batteries connected in series. Preferably, the number of plate bodies 1 arranged inside the automobile battery is four, so as to separate five placement spaces. The positive end of the battery located on the outermost side is connected to a positive pole, and the positive pole extends to the outside for connecting to the power distribution equipment. The negative end of the battery is provided with a busbar. The busbar belongs to the prior art. The multiple negative poles of the battery are connected together through the busbar to form a negative end. One end of the conductive unit 3 contacts and conducts with the busbar, and the other end contacts and conducts with the positive end of the battery adjacent to the battery. The remaining batteries are connected in series in sequence, and finally the negative end of the other battery located on the outermost side is connected to the negative pole, and the negative pole extends to the outside for connecting to the power distribution equipment, thereby forming a complete current path.

[0058] When a single battery is placed in the placement space, due to the arrangement of the ribs 4 and the buffer unit 2, an installation space is formed between the battery side wall and the plate body 1, and the conductive unit 3 is arranged in the installation space. Specifically, an embedding groove penetrating through the two sides of the plate body 1 is formed on the plate body 1, and the conductive unit 3 includes a conductive body 31 fixed in the embedding groove, and the conductive body 31 is a horizontally arranged conductive metal, and both ends of the conductive body 31 extend to the outside of the plate body 1. Conductive connectors 32 are respectively installed at both ends of the conductive body 31, and the conductive connectors 32 extend toward the battery in the placement space so as to be able to contact and conduct with the battery.

[0059] Furthermore, the conductive unit 3 also includes an insulating seat 33, which is fixed on the plate body 1 and has a mounting hole reserved therein, and the portion of the conductive body 31 extending to the outside of the plate body 1 is accommodated in the mounting hole. Furthermore, a rotating connection structure is adopted between the conductive connector 32 and the conductive body 31, so that the conductive connector 32 can rotate relative to the conductive body 31, and the rotation axis of the conductive connector 32 is preferably parallel to the length direction of the plate body 1, that is, the conductive connector 32 can rotate a certain angle in the vertical plane. Specifically, there is a first limit position and a second limit position within the active range of the conductive connector 32. When the conductive connector 32 is in the first limit position, the positive and negative terminals of the battery contact and conduct with the conductive connector 32; when the conductive connector 32 is in the second limit position, the two are disconnected. In conjunction with this, a receiving groove is provided on the insulating seat 33, and the receiving groove is connected to the mounting hole and passes through the surface of the insulating seat 33. When the conductive connector 32 rotates from the first limit position to the second limit position, the conductive connector 32 can be transferred into the receiving groove to be hidden.

[0060] The above is a detailed introduction to an automotive battery separator provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the present invention.
