Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plate installation technology, and in particular to a convenient installation housing for liquid cooling plates. Background Technology

[0002] Thermal management of battery systems is particularly important for electric vehicles. To address this, the industry has adopted liquid cooling plate heat dissipation, which uses liquid cooling plate trays to cool the battery modules.

[0003] Liquid cooling plates are typically located below the battery module, at the bottom of the battery pack housing. When the liquid cooling plate needs repair or replacement due to blockage, leakage, or performance degradation, traditional fixing methods (such as numerous bolts directly fixing it to the support structure) require maintenance personnel to disassemble it from the top of the battery pack. This usually involves removing the battery module itself or complex wiring harnesses, brackets, and other components above it to finally reach and operate the fasteners securing the liquid cooling plate. This makes the entire process cumbersome and time-consuming, significantly increasing labor costs and introducing additional risks of damage, such as loose connectors or battery module impacts, during repeated disassembly and reassembly of upper precision components. This causes great inconvenience for the installation, disassembly, and replacement of the liquid cooling plate. To address this, we propose a convenient mounting housing for liquid cooling plates. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a convenient mounting housing for liquid cooling plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a convenient mounting housing for a liquid cooling plate, comprising a protective shell, a support base provided on the bottom surface of the protective shell, a battery module placed on top of the support base, two sets of symmetrically arranged limiting components movably mounted on the bottom surface of the support base, a liquid cooling plate movably mounted between the support base and the limiting components, the liquid cooling plate specifically comprising a plate body, a protective plate detachably connected to the bottom surface of the limiting components, a fixing block fixedly mounted on the bottom surface of the support base between the two sets of limiting components, a limiting component rotatably mounted on the outer wall of the fixing block, the limiting component including a rack plate meshing with a gear, the meshing between the gear and the rack plate causing the two sets of limiting components to open to both sides simultaneously.

[0006] Preferably, the limiting component includes two first connecting rods, with a second connecting rod fixedly connected to one end of each of the two first connecting rods, a rack plate fixedly connected to the other end of the first connecting rods, and a first sliding rod fixedly installed on the upper surface of the first connecting rods, the first sliding rod being slidably connected to the support base.

[0007] Preferably, a first protrusion is fixedly installed at both ends of the plate, and a first fixing ear that mates with the first protrusion is fixedly installed on the inner wall of the second connecting rod, and a first bolt is threaded onto the first fixing ear.

[0008] Preferably, the outer walls on both sides of the plate are respectively fixedly installed with second protrusions, the inner wall of the first connecting rod is fixedly installed with second fixing ears that cooperate with the second protrusions, the second fixing ears are threadedly connected with second bolts, the second protrusions are provided with through holes, and the end of the second bolts is threadedly connected to the inner wall of the through holes.

[0009] Preferably, two symmetrically arranged clamping blocks are fixedly installed on the inner wall of the second connecting rod, and the ends of the clamping blocks are wedge-shaped.

[0010] Preferably, a second slide rod is fixedly installed at the end of each of the two first connecting rods, and the second slide rod is slidably connected to the fixed block.

[0011] Preferably, the inner wall of the support base is fixedly equipped with two symmetrically arranged support ribs, and the bottom surface of the battery module is provided with relief grooves on both sides to cooperate with the support ribs. Beneficial effects

[0012] This invention provides a convenient mounting housing for liquid cooling plates. It offers the following advantages: (1) The convenient mounting housing for liquid cooling plates can be driven by pulling the second connecting rod on one side, and the meshing transmission of the gear and the rack plates on both sides can be used to drive the two sets of limiting components to open outward, exposing the installation space at the bottom of the support base. After the liquid cooling plate is installed, the limiting components can be reset by reversing the operation. Combined with the detachable bottom guard plate, maintenance personnel do not need to disassemble the entire battery pack or a large number of upper components. They only need to remove the guard plate from the bottom of the vehicle and operate the limiting components to complete the removal or installation of the liquid cooling plate, which greatly simplifies the operation steps and reduces the maintenance difficulty and time cost.

[0013] (2) The convenient mounting housing for liquid cooling plate applies upward extrusion force to both ends of the liquid cooling plate through wedge-shaped clamping blocks, forcing the upper surface of the liquid cooling plate to fit tightly against the bottom surface of the support base, thereby ensuring the effective contact area between the upper surface of the liquid cooling plate and the bottom surface of the battery module. Then, the first bolt is screwed into the first fixing ear and abuts against the first protrusions at both ends of the liquid cooling plate to provide vertical fastening force. At the same time, the support ridge on the support base cooperates with the clearance groove on the bottom surface of the battery module, which provides direct contact space for the liquid cooling plate while supporting the battery module, thus ensuring the smooth flow of heat dissipation channels and heat conduction efficiency.

[0018] 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.

[0019] like Figure 1-7 As shown, a convenient mounting housing for a liquid cooling plate 8 includes a protective shell 1. A support base 2 is provided on the bottom surface of the protective shell 1. A battery module 5 is placed on top of the support base 2. Two sets of symmetrically arranged limiting components 3 are movably mounted on the bottom surface of the support base 2. A liquid cooling plate 8 is movably mounted between the support base 2 and the limiting components 3. The liquid cooling plate 8 specifically includes a plate body 801. A protective plate 4 is detachably connected to the bottom surface of the limiting components 3. A fixing block 10 is fixedly mounted on the bottom surface of the support base 2 between the two sets of limiting components 3. The outer wall of the fixing block 10 is rotatably mounted with the limiting components 3. The limiting components 3 include a rack plate 309 that meshes with a gear 9. The meshing between the rack plate 309 and the gear 9 causes the two sets of limiting components 3 to open to both sides simultaneously. The user can move the two sets of limiting components 3 to both sides by pulling the second connecting rod 302. Under the action of the gear 9, when the user pulls one of the second connecting rods 302, one of the rack plates 309 meshes with the gear 9, causing the gear 9 to rotate. Under the indirect transmission of the gear 9, the other set of limiting components 3 can be pulled outward. Then, the user can directly place the liquid cooling plate 8 between the support base 2 and the limiting components 3, and then reset the two sets of limiting components 3 to install the liquid cooling plate 8 between the support base 2 and the limiting components 3.

[0020] like Figure 4 As shown, the limiting component 3 includes two first connecting rods 301, with a second connecting rod 302 fixedly connected to one end of each first connecting rod 301. A rack plate 309 is fixedly connected to the other end of the first connecting rod 301. A first sliding rod 306 is fixedly installed on the upper surface of the first connecting rod 301, and the first sliding rod 306 is slidably connected to the support base 2. A rectangular plate is fixedly installed at the end of the first sliding rod 306, and the first sliding rod 306 is fixedly connected to the first connecting rod 301 through the rectangular plate. That is, the first sliding rod 306 and the first connecting rod 301 are arranged in parallel. When the limiting component 3 moves towards both ends of the support base 2, the first connecting rod 301 is kept connected to the support base 2 through the first sliding rod 306, and the first connecting rod 301 slides on the bottom surface of the support base 2 through the first sliding rod 306.

[0021] like Figure 3As shown, first protrusions 802 are fixedly installed at both ends of the plate 801, and first fixing ears 304 that cooperate with the first protrusions 802 are fixedly installed on the inner wall of the second connecting rod 302. A first bolt 305 is threaded onto the first fixing ears 304. The user can fix the liquid cooling plate 8 again by rotating the first bolt 305 and the second bolt 308. The upper end of the first bolt 305 can press the first protrusion 802 together to tighten the liquid cooling plate 8 as a whole.

[0022] like Figure 7 As shown, second protrusions 803 are fixedly installed on the outer walls of both sides of the plate 801. A second fixing ear 307 that mates with the second protrusion 803 is fixedly installed on the inner wall of the first connecting rod 301. A second bolt 308 is threadedly connected to the second fixing ear 307. A through hole is opened through the second protrusion 803, and the end of the second bolt 308 is threadedly connected to the inner wall of the through hole. The upper end of the second bolt 308 is threadedly connected to the through hole opened on the second protrusion 803, which can prevent the liquid cooling plate 8 from shifting due to loosening during use.

[0023] like Figure 5 As shown, two symmetrically arranged clamping blocks 303 are fixedly installed on the inner wall of the second connecting rod 302, and the ends of the clamping blocks 303 are wedge-shaped. The clamping blocks 303 with wedge-shaped ends can press the two ends of the liquid cooling plate 8 against the bottom surface of the support base 2, thereby ensuring that the upper surface of the liquid cooling plate 8 remains in contact with the bottom surface of the battery module 5 in the subsequent process, and ensuring the heat dissipation effect of the liquid cooling plate 8 on the battery module 5.

[0024] like Figure 4 As shown, a second slide bar 310 is fixedly installed at the end of each of the two first connecting rods 301. The second slide bar 310 is slidably connected to the fixed block 10. The setting of the second slide bar 310 can ensure that the first connecting rod 301 and the fixed block 10 are always connected, thereby enhancing the connection strength between the limiting component 3 and the fixed block 10.

[0025] like Figure 2 As shown, two symmetrically arranged support ribs 6 are fixedly installed on the inner wall of the support base 2. The bottom surface of the battery module 5 is provided with relief grooves 7 on both sides to cooperate with the support ribs 6. The battery module 5 is located inside the protective shell 1. The shell composed of the protective shell 1 and the support base 2 protects the battery module 5. The relief grooves 7 are provided on both sides of the bottom surface of the battery module 5. The relief grooves 7 cooperate with the support ribs 6 fixedly installed inside the support base 2. The support ribs 6 can support the bottom surface of the battery module 5 on both sides. It can also make the bottom surface of the battery module 5 directly contact the liquid cooling plate 8 located below the support base 2 to ensure the heat dissipation effect of the liquid cooling plate 8 on the battery module 5.

[0026] The working principle of this utility model is as follows: In use, the battery module 5 is located inside the protective shell 1. The shell 1 and the support base 2 together protect the battery module 5. Both sides of the bottom surface of the battery module 5 have clearance grooves 7, which cooperate with the support ribs 6 fixedly installed inside the support base 2. The support ribs 6 support both sides of the bottom surface of the battery module 5 and allow the bottom surface of the battery module 5 to directly contact the liquid cooling plate 8 located below the support base 2, ensuring the heat dissipation effect of the liquid cooling plate 8 on the battery module 5. When installing the liquid cooling plate 8, the user can move the two sets of limiting components 3 to the sides by pulling the second connecting rod 302. Under the action of the gear 9, when the user pulls one of the second connecting rods 302, one of the rack plates 309 meshes with the gear 9, causing the gear 9 to rotate. This indirect transmission from the gear 9 pulls the other set of limiting components 3 outwards. The user then places the liquid cooling plate 8 between the support base 2 and the limiting components 3, and then resets the two sets of limiting components 3. At this point, the limiting components 3 are fixed... The installed clamping block 303 can squeeze and limit the two ends of the liquid cooling plate 8, ensuring that the upper surface of the liquid cooling plate 8 is in contact with the bottom surface of the battery module 5 after the battery module 5 is installed. Then, the user can fix the liquid cooling plate 8 again by rotating the first bolt 305 and the second bolt 308. The upper end of the first bolt 305 can press the first protrusion 802, and the upper end of the second bolt 308 is threadedly connected to the through hole on the second protrusion 803, which can prevent the liquid cooling plate 8 from shifting due to loosening during use. The battery module 5 and the liquid cooling plate 8 are both assembled. After installation, the user can fasten the protective plate 4 to the bottom surface of the limiting component 3 with screws, etc. In this device, the liquid cooling plate 8 is set on the bottom surface of the support base 2. When the liquid cooling plate 8 has a fixing failure and needs to be replaced separately, the maintenance personnel can directly remove the protective plate 4 from the bottom surface of the vehicle and then open the two sets of limiting components 3 to both ends to directly remove the liquid cooling plate 8. There is no need to disassemble the entire battery pack, which simplifies the disassembly steps, facilitates the disassembly and replacement of the liquid cooling plate 8, and improves the practicality of the device.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
