Description

Technical Field

[0001] This utility model relates to the field of water tap technology, specifically a battery cooling water tap with an inner and outer sealing structure. Background Technology

[0002] As an important component of new energy vehicles, the battery pack plays a crucial role in providing energy for these vehicles. To ensure the normal operation of the cells within the battery pack, liquid cooling plates are typically installed on the new energy battery box to cool the cells with water. The water nozzle is the inlet and outlet connector of the water cooling component. During the water cooling process of the new energy battery, the coolant is transported through the coolant pipes and sprayed out from the water nozzle.

[0003] Currently, water nozzles are typically installed using threaded fixing or welding. The water nozzle is threaded onto the connection of the liquid cooling plate or directly welded to the liquid cooling plate to achieve a sealing effect. However, due to vibrations during vehicle operation, the threads may loosen over time. In addition, welding reliability is generally low, and cracking is prone to occur. Both situations can lead to water leakage at the connection, resulting in poor sealing performance of the water nozzle and reducing the stability of the water nozzle seal. To address this, we propose a battery cooling water nozzle with an internal and external sealing structure. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background, the present invention provides a battery cooling water nozzle with an inner and outer sealing structure.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A battery cooling water nozzle with an internal and external sealing structure includes: a liquid cooling plate and two water nozzles. The top of the liquid cooling plate is connected to two connection ports. The outer and inner surfaces of the two water nozzles are respectively provided with a first sealing component and a second sealing component. The two water nozzles are respectively sleeved on the outer surfaces of the two connection ports. The two first sealing components and the two second sealing components are respectively abutted to the top of the two connection ports and the outer surfaces of the two water nozzles. The outer surfaces of the two water nozzles are provided with positioning mechanisms. The top of the liquid cooling plate is provided with four locking mechanisms, and the two positioning mechanisms are movably inserted into the four locking mechanisms.

[0007] As a further embodiment of the present invention: the first sealing assembly includes a first annular plate, a first spring and a first sealing ring. The first annular plate is connected to the outer surface of one of the water nozzles, the first spring is connected to the bottom of the first annular plate, the first sealing ring is connected to the bottom end of the first spring, and the first sealing ring is attached to the lower part of the outer surface of one of the water nozzles.

[0008] As a further improvement of this invention: the first spring is located on the outer surface of one of the water taps.

[0009] As a further embodiment of this utility model: the second sealing assembly includes a second annular plate, a second spring, and a second sealing ring. The second annular plate is connected to the inner surface of one of the water nozzles, the second spring is connected to the bottom of the second annular plate, the second sealing ring is connected to the bottom end of the second spring, and the second sealing ring is in contact with the top of one of the connection ports.

[0010] As a further embodiment of this utility model: the positioning mechanism includes a mounting plate, two insert rods and four trapezoidal holes. The mounting plate is connected to the outer surface of one of the water nozzles, and both insert rods are connected to the bottom of the mounting plate. The outer surface of each insert rod has two trapezoidal holes.

[0011] As a further embodiment of this utility model: the locking mechanism includes a sleeve, two sliding rods, two trapezoidal blocks, two handles, and two pressure springs. The sleeve is connected to the top of the liquid cooling plate. Both sliding rods are slidably connected to the outer surface of the sleeve, and one end of each sliding rod extends into the interior of the sleeve. The two trapezoidal blocks are respectively connected to one end of each sliding rod. The two handles are respectively connected to the other end of each sliding rod. Both pressure springs are connected to the outer surface of the sleeve, and one end of each pressure spring is connected to the side adjacent to the two handles. The two pressure springs are respectively located outside the two sliding rods.

[0012] As a further embodiment of this utility model, the two trapezoidal blocks are respectively movably inserted into the interior of two trapezoidal holes on the outer surface of one of the plug rods.

[0013] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0014] 1. In this utility model, the two water taps can be installed with internal and external seals through the action of two first sealing components and two second sealing components, so as to achieve stable and tight contact and realize the effect of double sealing, thereby effectively preventing leakage of the two water taps and improving the stability of the seal of the two water taps.

[0015] 2. In this utility model, the two positioning mechanisms and four locking mechanisms enable the two water nozzles to be fixed at the two connection ports by plugging them in. This eliminates the need for workers to use tools to twist the two water nozzles and install them by threaded connection, thus avoiding the problem of the two water nozzles becoming loose after long-term use. This not only improves the stability after installation but also makes it easier to replace the two water nozzles. Attached Figure Description

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1-5 In this embodiment of the present invention, a battery cooling water nozzle with an inner and outer sealing structure includes: a liquid cooling plate 1 and two water nozzles 2. The top of the liquid cooling plate 1 is connected to two connection ports 3. The outer and inner surfaces of the two water nozzles 2 are respectively provided with a first sealing component 4 and a second sealing component 5. The two water nozzles 2 are respectively sleeved on the outer surfaces of the two connection ports 3. The two first sealing components 4 and the two second sealing components 5 are respectively in contact with the top of the two connection ports 3 and the outer surfaces of the two water nozzles 2. The outer surfaces of the two water nozzles 2 are each provided with a positioning mechanism 6. The top of the liquid cooling plate 1 is provided with four locking mechanisms 7, and the two positioning mechanisms 6 are respectively movably inserted into the four locking mechanisms 7.

[0025] Specifically, after the two water nozzles 2 are fitted onto the outer surfaces of the two connecting ports 3, the bottoms of the two water nozzles 2 are made to fit against the top of the liquid cooling plate 1. At this time, the two first sealing components 4 and the two second sealing components 5 respectively seal the lower part of the outer surface of the two water nozzles 2 and the top of the two connecting ports 3, thus achieving the effect of sealing the inside and outside of the two water nozzles 2. While the two water nozzles 2 are fitted onto the outer surfaces of the two connecting ports 3, the two positioning mechanisms 6 will be inserted into the interior of the four locking mechanisms 7. At this time, the four locking mechanisms 7 will lock the two positioning mechanisms 6, thereby fixing the two water nozzles 2 onto the two connecting ports 3 by locking the two positioning mechanisms 6, thus realizing the installation of the two water nozzles 2.

[0026] Example 2:

[0027] Please see Figures 2-3 In this embodiment of the present invention, a battery cooling water nozzle with an inner and outer sealing structure includes a first sealing assembly 4 comprising a first annular plate 401, a first spring 402, and a first sealing ring 403. The first annular plate 401 is connected to the outer surface of one of the water nozzles 2, the first spring 402 is connected to the bottom of the first annular plate 401, and the first sealing ring 403 is connected to the bottom end of the first spring 402 and is attached to the lower part of the outer surface of one of the water nozzles 2. The first spring 402 is located on the outer surface of one of the water nozzles 2. The second sealing assembly 5 comprises a second annular plate 501, a second spring 502, and a second sealing ring 503. The second annular plate 501 is connected to the inner surface of one of the water nozzles 2, the second spring 502 is connected to the bottom of the second annular plate 501, and the second sealing ring 503 is connected to the bottom end of the second spring 502 and is attached to the top of one of the connection ports 3.

[0028] Specifically, pressing one of the water nozzles 2 down on the outer surface of one of the connection ports 3 causes the outer surface of the first sealing ring 403 to adhere to the top of the liquid cooling plate 1 and the lower part of the outer surface of one of the water nozzles 2. At this time, the first spring 402 will be compressed and pressed to seal the outside of one of the water nozzles 2. Meanwhile, the second sealing ring 503 adheres to the inner surface of one of the water nozzles 2 and the top of one of the connection ports 3. At the same time, the second spring 502 is compressed and pressed to seal the inside of one of the water nozzles 2, thereby achieving a double seal for one of the water nozzles 2.

[0029] Example 3:

[0030] Please see Figures 4-5In this embodiment of the present invention, a battery cooling water nozzle with an inner and outer sealing structure includes a positioning mechanism 6 comprising a mounting plate 601, two insert rods 602, and four trapezoidal holes 603. The mounting plate 601 is connected to the outer surface of one of the water nozzles 2. Both insert rods 602 are connected to the bottom of the mounting plate 601, and each of the two insert rods 602 has two trapezoidal holes 603 on its outer surface. The locking mechanism 7 comprises a sleeve 701, two sliding rods 702, two trapezoidal blocks 703, two handles 704, and two pressure springs 705. The sleeve 701 is connected to the top of the liquid cooling plate 1, and both sliding rods 702 are slidably connected. The sleeve 701 is attached to the outer surface of the sleeve 701, and one end of each of the two slide rods 702 extends into the interior of the sleeve 701. Two trapezoidal blocks 703 are respectively connected to one end of each of the two slide rods 702. Two handles 704 are respectively connected to the other end of each of the two slide rods 702. Two pressure springs 705 are both connected to the outer surface of the sleeve 701, and one end of each of the two pressure springs 705 is respectively connected to the side adjacent to the two handles 704. The two pressure springs 705 are respectively located outside the two slide rods 702. The two trapezoidal blocks 703 are respectively movably inserted into the interior of the two trapezoidal holes 603 on the outer surface of one of the insert rods 602.

[0031] Specifically, when the mounting plate 601 descends, one of the insert rods 602 will be inserted into the sleeve 701. The bottom end of one of the mounting plates 601 will press against the two trapezoidal blocks 703 to move in opposite directions, thereby driving the two sliding rods 702 to slide in opposite directions, causing the two pressure springs 705 to stretch. When the two trapezoidal holes 603 on the outer surface of one of the insert rods 602 are flush with the two trapezoidal blocks 703, one of the insert rods 602 will no longer press against the two trapezoidal blocks 703. At this time, the two pressure springs 705 will reset, driving the two trapezoidal blocks 703 to insert into the two insert rods 602, locking one of the insert rods 602, thus fixing one of the water nozzles 2 to the outer surface of one of the connection ports 3.

[0032] The working principle of this utility model is as follows: When one of the water nozzles 2 needs to be installed, after fitting one of the water nozzles 2 onto the outer surface of one of the connecting ports 3, press one of the water nozzles 2 down onto the outer surface of one of the connecting ports 3. At this time, the outer surface of the first sealing ring 403 is in contact with the top of the liquid cooling plate 1 and the lower part of the outer surface of one of the water nozzles 2. At the same time, the first spring 402 is compressed and pressed, thus achieving a seal on the outside of one of the water nozzles 2. Meanwhile, the second sealing ring 503 is in contact with the inner surface of one of the water nozzles 2 and the top of one of the connecting ports 3. At the same time, the second spring 502 is compressed and pressed, thus achieving a seal on the inside of one of the water nozzles 2. One of the water nozzles 2 is fitted onto the outer surface of one of the connecting ports 3. Simultaneously, one of the insert rods 602 at the bottom of the mounting plate 601 will be inserted into the sleeve 701. As one of the insert rods 602 continues to descend, it will compress the two trapezoidal blocks 703 to move in opposite directions, and drive the two sliding rods 702 to slide outwards from the sleeve 701. At the same time, the two pressure springs 705 will be stretched. When the two trapezoidal holes 603 on the outer surface of one of the insert rods 602 are flush with the two trapezoidal blocks 703, one of the insert rods 602 will no longer compress the two trapezoidal blocks 703. At this time, the two pressure springs 705 will reset, driving the two trapezoidal blocks 703 to insert into the two insert rods 602, locking one of the insert rods 602, thus fixing one of the water nozzles 2 onto one of the connection ports 3, completing the installation of one of the water nozzles 2.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
