Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate technology, specifically to an assembled battery box liquid cooling plate. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. When a battery is working, it generates a lot of heat. In order to dissipate the heat and ensure the normal use of the battery, it is necessary to cool the battery. The existing cooling method usually uses liquid cooling plates. However, the existing liquid cooling plates for battery boxes still have certain defects in use.

[0003] As proposed in application number CN202321234803.4, an assembled battery liquid cooling plate structure includes a plate body one and a positioning assembly. A plate body two is connected to the right side of the plate body one, and a plate body three is located on the right side of the plate body two. The positioning assembly for quick assembly and disassembly is located on the left and right sides of the plate body two. The positioning assembly includes a sliding plate, a pressure plate, a spring, a locking plate, a fixing plate, and a slot. Through the positioning assembly, this assembled battery liquid cooling plate structure allows the fixing plates on the plate bodies two and three to be inserted into the plates on the plate bodies one and two during assembly of the battery liquid cooling plate. Within the groove, the spring pushes the pressure plate, causing the sliding plate to pull the locking plate to move, thereby engaging with the fixing plate through the slot to assemble plate one, plate two, and plate three. Simultaneously, when adjusting the overall length of the battery liquid cooling plate, simply add the corresponding number of plate two, thus expanding the adaptability range of the battery liquid cooling plate. However, in actual use, the positioning component protrudes from the liquid cooling plate structure, making it prone to accidental contact and separation during subsequent installation, reducing assembly stability and the integrated effect of the battery liquid cooling plate.

[0004] Therefore, we propose an assembled battery box liquid cooling plate to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an assembled battery box liquid cooling plate to solve the problem mentioned in the background art that the positioning components are easily accidentally touched during the installation process, causing separation, reducing assembly stability and the integrated effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an assembled battery box liquid cooling plate, including a positioning plate.

[0007] A cooling cavity is installed inside the positioning plate. A receiving seat is fixedly installed on one side of the middle part of the positioning plate, and a plug-in seat is fixedly installed on the other side of the middle part of the positioning plate.

[0008] Positioning connection mechanisms are installed at both ends of the positioning plate.

[0009] The cooling cavity is equipped with sealing docking mechanisms at both ends.

[0010] Preferably, the cooling cavity is distributed in an "M" shape inside the positioning plate, and the groove of the receiving seat matches the size of the protrusion of the plug seat.

[0011] The design of the above structure allows for an extension of the coolant circulation path, thereby increasing the cooling range of the coolant inside the cooling chamber on the batteries inside the battery box and improving the cooling effect. The cooperation between the receiving seat and the plug seat enables relative positioning of the assembled positioning plate, preventing misalignment and improving the stability of the assembly.

[0012] Preferably, the positioning and connecting mechanism includes a connecting seat symmetrically fixedly installed on one side of the positioning plate, and the connecting seat has a snap-fit ​​groove inside.

[0013] Preferably, the positioning connection mechanism further includes a fixed seat symmetrically fixedly installed on the other side of the positioning plate. A limiting seat is symmetrically installed on the side of the fixed seat away from the positioning plate. A limiting groove is formed inside the limiting seat. A movable plate is slidably installed inside the limiting groove. A return spring is fixedly connected between the movable plate and the bottom surface of the limiting groove. A snap-fit ​​block is fixedly installed on the top surface of the movable plate. The snap-fit ​​block is slidably connected to the limiting seat through it.

[0014] Preferably, five sets of reset springs are provided between the bottom surfaces of the movable plate and the limiting groove, and the locking block and the movable plate form a telescopic structure with the limiting groove through the reset springs, and the locking block is arranged in a right-angled trapezoidal structure.

[0015] The above-mentioned structural design facilitates the positioning and connection of multiple positioning plates through the snap-fit ​​connection of the positioning and connecting mechanism. The integrated design of the positioning and connecting mechanism and the positioning plate can avoid protrusion at the edges, thereby preventing accidental contact and separation during subsequent installation. This improves the integration effect and assembly stability of the assembled battery box liquid cooling plate.

[0016] Preferably, the sealing and docking mechanism includes a connecting pipe fixedly installed inside one end of the cooling cavity, and a sealing plug fixedly installed inside the other end of the cooling cavity. One end of the sealing plug has a fitting groove on its outer ring, and the outer ring size of the fitting groove matches the inner ring size of the connecting pipe.

[0017] The above-mentioned structural design facilitates the sealing and docking of multiple cooling chambers through a sealing docking mechanism, thereby effectively preventing leakage at the docking points of the cooling chambers and improving the assembly sealing performance of the liquid cooling plate of the assembled battery box.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the assembled battery box liquid cooling plate;

[0019] The structure of the cooling chamber can effectively extend the circulation path of the coolant, thereby facilitating more comprehensive cooling of the batteries inside the battery box and improving the performance. The cooperation between the receiving seat and the plug seat can relatively limit the positioning plate after splicing, preventing the positioning plate from being misaligned during subsequent use and improving the assembly stability.

[0020] The positioning and connecting mechanism facilitates the fitting connection between multiple positioning plates. Moreover, the positioning and connecting mechanism and the positioning plates are integrated into one structure, which can prevent accidental separation during subsequent installation and thus improve the stability of assembly. The sealing docking mechanism can seal the cooling cavities inside the multiple positioning plates, thereby preventing leakage at the connection and improving the assembly sealing effect of the liquid cooling plate of the assembled battery box.

[0027] 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.

[0028] Please see Figure 1-5 This utility model provides a technical solution: an assembled battery box liquid cooling plate, including a positioning plate 1, a cooling cavity 2 installed inside the positioning plate 1, the cooling cavity 2 being distributed in an "M" shape inside the positioning plate 1, a receiving seat 3 being fixedly installed on one side of the middle of the positioning plate 1, and a plug seat 4 being fixedly installed on the other side of the middle of the positioning plate 1, the groove of the receiving seat 3 matching the size of the protrusion of the plug seat 4;

[0029] The above-mentioned structural design allows the receiving seat 3 and the plug seat 4 to be plugged into each other when assembling multiple sets of positioning plates 1. This enables the docking of the middle part of the positioning plates 1 to be mutually limited, preventing misalignment during subsequent use. The structure of the cooling cavity 2 extends the path of the coolant, increases the contact area between the cooling cavity 2 and the battery inside the battery box, and improves the cooling effect.

[0030] Positioning connection mechanisms are installed at both ends of the positioning plate 1. The positioning connection mechanism includes a connecting seat 5 symmetrically fixedly installed on one side of the positioning plate 1. The connecting seat 5 has a snap-fit ​​groove 6 inside. The positioning connection mechanism also includes a fixing seat 7 symmetrically fixedly installed on the other side of the positioning plate 1. A limiting seat 8 is symmetrically installed on the side of the fixing seat 7 away from the positioning plate 1. A limiting groove 9 is opened inside the limiting groove 9. A movable plate 10 is slidably installed inside the limiting groove 9. A return spring 11 is fixedly connected between the movable plate 10 and the bottom surface of the limiting groove 9. Five sets of return springs 11 are arranged between the bottom surfaces of the movable plate 10 and the limiting groove 9. The snap-fit ​​block 12 and the movable plate 10 form a telescopic structure with the limiting groove 9 through the return spring 11. The snap-fit ​​block 12 is fixedly installed on the top surface of the movable plate 10. The snap-fit ​​block 12 is arranged in a right trapezoidal structure. The snap-fit ​​block 12 is slidably connected to the limiting seat 8 through.

[0031] The above-described structure design allows the connecting seat 5 and the fixed seat 7 installed on adjacent positioning plates 1 to fit tightly during assembly. The limiting seat 8 fixedly installed on the fixed seat 7 then inserts into the snap-fit ​​groove 6 inside the connecting seat 5. The return spring 11 pushes the movable plate 10 back to its original position, causing the movable plate 10 to drive the snap-fit ​​block 12 out of the limiting seat 8 and engage with the snap-fit ​​groove 6. This allows for the positioning connection of the connecting seat 5 and the fixed seat 7, and the positioning connection of adjacent positioning plates 1, thus improving the convenience and stability of assembly. Disassembly simply involves squeezing the snap-fit ​​block 12 to retract it, releasing the engagement between the snap-fit ​​block 12 and the snap-fit ​​groove 6. This facilitates the removal of the limiting seat 8 from the snap-fit ​​groove 6, separating the connecting seat 5 from the fixed seat 7 and disassembling adjacent positioning plates 1. The limiting groove 9 limits the extension and retraction of the movable plate 10.

[0032] The cooling cavity 2 is equipped with sealing docking mechanisms at both ends. The sealing docking mechanism includes a connecting pipe 13 fixedly installed inside one end of the cooling cavity 2, and a sealing plug 14 fixedly installed inside the other end of the cooling cavity 2. A fitting groove 15 is opened on the outer ring of one end of the sealing plug 14, and the outer ring size of the fitting groove 15 matches the inner ring size of the connecting pipe 13.

[0033] The design of the above structure allows the cooling chambers 2 inside the positioning plates 1 to be connected when the multiple positioning plates 1 are assembled. As a result, the connecting pipe 13 inside one cooling chamber 2 will be inserted into the cooling chamber 2 on the adjacent side, and the inner ring of the connecting pipe 13 will be tightly connected to the fitting groove 15 of the outer ring of the sealing plug 14. This helps to effectively seal the connection between adjacent cooling chambers 2, avoid leakage, and improve the assembly sealing effect.

[0034] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention 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 invention should be included within the protection scope of the present invention.
