Description

Technical Field

[0001] This utility model belongs to the field of battery technology and relates to a water tap, a detachable connector assembly, and a battery system. Background Technology

[0002] With the rapid development of new energy vehicles and the energy storage industry, the market has placed higher demands on the thermal management efficiency, lightweight design, and ease of maintenance of battery systems. Battery liquid cooling technology, due to its high heat transfer coefficient and precise temperature control capabilities, has become the primary thermal management solution.

[0003] In liquid cooling systems, the water nozzle, as a core connecting component, plays a crucial role in coolant circulation and sealing. Currently, the main design of water nozzles in the industry adopts a claw-type quick-connect structure, which uses elastic claws to achieve a detachable connection with the connector. However, when installing or removing the water nozzle, it is necessary to simultaneously open the claws on both sides, which not only requires a large operating space but also requires the operator to apply considerable force, resulting in inconvenience. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a water tap, a detachable connector assembly, and a battery system.

[0005] The objective of this utility model can be achieved through the following technical solution: a water tap, comprising:

[0006] The faucet body has a groove on its circumferential surface;

[0007] A fastener is sleeved on the faucet body, the fastener is provided with an elastic claw, the elastic claw engages with the slot, and the elastic claw is provided with a first inclined surface;

[0008] The unlocking component is sleeved on the faucet body and can move along the axial direction of the faucet body. The unlocking component is provided with a top block and the top block is provided with a second inclined surface.

[0009] When the unlocking member moves in the direction that causes the top block to push against the elastic claw, the first inclined surface and the second inclined surface interact to force the elastic claw to tilt away from the slot; when the elastic claw tilts to a predetermined position, the elastic claw separates from the slot and the faucet body is allowed to move relative to the latching member.

[0010] Preferably, the unlocking component is rotatably connected to the water nozzle body, and the outer wall of the unlocking component is provided with one of a drive groove and a drive block.

[0011] Preferably, the unlocking component is rotatably connected to the faucet body, and the outer wall of the unlocking component is provided with one of a limiting groove and a limiting block.

[0012] Preferably, the fastener has a snap-fit ​​block for fixed connection with the connector.

[0013] Preferably, the latching member is provided with at least two elastic claws, the slot is configured as an annular groove structure, and the number of top blocks of the unlocking member is the same as the number of elastic claws and they are configured in a one-to-one correspondence.

[0014] A detachable connector assembly includes the aforementioned faucet and a connector, wherein a snap fastener is fixedly connected to the connector via a snap-fit ​​block, the faucet body is mated to the connector, and the faucet body is held fixed to the connector via the snap fastener.

[0015] Preferably, the unlocking member is rotatably connected to the connector, the connector being provided with one of a drive groove and a drive block, the drive block being slidably connected to the drive groove; when the unlocking member rotates relative to the connector, the drive block and the drive groove force the unlocking member to move axially.

[0016] Preferably, the unlocking component is rotatably connected to the connector, the connector being provided with one of a limiting groove and a limiting block, the limiting block being slidably connected to the limiting groove, both ends of the limiting groove having limiting positions, the two limiting positions being located at different positions along the axial direction of the faucet body; when the unlocking component is in the locked position, the limiting block is in one of the limiting positions, and when the unlocking component is in the unlocked position, the limiting block is in the other of the limiting positions; when the limiting block is in the limiting position, the unlocking component is restricted from moving along the axial direction of the faucet body.

[0017] Preferably, the faucet body is inserted into the connector, and two sealing rings are provided between the faucet body and the connector, with an isolation ring provided between the two sealing rings.

[0018] A battery system includes the aforementioned detachable connector assembly, and further includes a liquid cooling pipeline connected to the connector via a water nozzle body, wherein a cooling medium can enter the liquid cooling pipeline through the connector and the water nozzle body.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. The unlocking component can move in the axial direction to push the elastic claw, and the interaction of the two inclined surfaces forces the elastic claw to lift up, thereby installing or removing the water nozzle body.

[0021] 2. The drive sloping groove or drive sloping block forms a thread-like structure. When the unlocking part rotates, the axial displacement of the unlocking part can be achieved through the interaction between the inclined surfaces. The rotational motion is converted into axial motion by using the thread mechanism. Compared with the method of directly pushing the unlocking part along the axial direction, it is more labor-saving and requires less operating space.

[0022] 3. Because the snap-fit ​​component is fixedly connected to the connector, and the snap-fit ​​component can be detachably connected to the faucet body via elastic claws, the faucet body and connector can be detachably connected. When the faucet body and snap-fit ​​component are locked together, the faucet body is perfectly aligned with the connector. This design simplifies the installation and disassembly process, enabling quick assembly and disassembly, and facilitating routine maintenance and repair. Attached Figure Description

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figures 1 to 7As shown, a water tap includes: a water tap body 100, with a groove 110 formed on its circumferential surface; a fastener 200 sleeved on the water tap body 100, the fastener 200 having an elastic claw 210 that engages with the groove 110, the elastic claw 210 having a first inclined surface 211; and an unlocking member 300 sleeved on the water tap body 100, the unlocking member 300 being movable along the axial direction of the water tap body 100, the unlocking member 300 having a top block 310. 310 is provided with a second inclined surface 311, and the top block 310 is aligned with the elastic claw 210 in the circumferential direction; when the unlocking member 300 moves in the direction that causes the top block 310 to push the elastic claw 210, the first inclined surface 211 and the second inclined surface 311 interact to force the elastic claw 210 to tilt away from the slot 110; when the elastic claw 210 tilts to a predetermined position, the elastic claw 210 separates from the slot 110 and the faucet body 100 is allowed to move relative to the latching member 200.

[0033] The faucet body 100 is a tubular structure, and the fastener 200 is a sleeve-like structure. The fastener 200 is used to fix the faucet body 100 to the connector 400. The faucet body 100 is inserted into the fastener 200, and the elastic claw 210 can engage the slot 110, thereby axially fixing the faucet body 100 and the fastener 200 together, thus fixing the faucet body 100 to the connector 400. The elastic claw 210 can be tilted in the radial direction. When tilted, it can separate from the slot 110, facilitating the installation or removal of the faucet body 100.

[0034] The unlocking component 300 is fitted onto the faucet body 100. Its main function is to drive the elastic claw 210 to deform and lift up through its own axial displacement, thereby separating the latching component 200 from the faucet body 100. The elastic claw 210 is provided with a first inclined surface 211, and the top block 310 is provided with a second inclined surface 311. During the axial movement of the unlocking component 300, the first inclined surface 211 and the second inclined surface 311 are in contact, and the axial thrust of the unlocking component 300 is converted into a radial thrust applied to the elastic claw 210, thereby forcing the elastic claw 210 to lift up.

[0035] In principle, the user only needs to rotate or push the unlocking member 300 to move it axially, thus releasing the axial lock of the latching member 200 on the faucet body 100. In the actual structure, the unlocking member 300 can be moved to either the locked or unlocked position. When the unlocking member 300 is in the locked position, the elastic claw 210 engages with the slot 110. When the unlocking member 300 moves toward the unlocked position, the top block 310 pushes the elastic claw 210 through the first and second inclined surfaces 211, gradually increasing the upward tilt of the elastic claw 210. When the unlocking member 300 reaches the unlocked position, the elastic claw 210 tilts to a position where it separates from the slot 110, at which point the faucet body 100 is allowed to move relative to the latching member 200.

[0036] When installing or removing the faucet body 100, this design eliminates the need to manually open the elastic claw 210. Instead, the unlocking component 300 can be used to push the elastic claw 210, which reduces the space requirements and the operator does not need to apply much force, thus reducing the difficulty of operation.

[0037] Example 1:

[0038] like Figures 2 to 4 , Figure 6 As shown, the unlocking member 300 is rotatably connected to the faucet body 100. The outer wall of the unlocking member 300 is provided with one of a drive groove 320 and a drive block 410. One of the drive groove 320 and the drive block 410 can cooperate with the other of the drive groove 320 and the drive block 410 of the connector 400, so that the rotational motion of the unlocking member 300 is converted into motion along the axial direction of the faucet body 100.

[0039] In Embodiment 1, the unlocking component 300 is designed as a knob structure, allowing it to rotate circumferentially around the faucet body 100. The outer wall of the unlocking component 300 is provided with either a drive groove 320 or a drive block 410, while the connector 400 is correspondingly provided with the other (i.e., if the unlocking component 300 has a drive groove 320, then the connector 400 has a drive block 410, and vice versa). The drive groove 320 or the drive block 410 forms a thread-like structure, allowing axial displacement of the unlocking component 300 to be achieved through the interaction between the inclined surfaces when the unlocking component 300 rotates.

[0040] This embodiment utilizes a threaded mechanism to convert rotational motion into axial motion, which is more labor-saving than directly pushing the unlocking component 300 along the axial direction and requires less operating space.

[0041] Example 2:

[0042] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the unlocking component 300 is rotatably connected to the faucet body 100. The outer wall of the unlocking component 300 is provided with one of a limiting groove 330 and a limiting block 420. One of the limiting groove 330 and the limiting block 420 can cooperate with the other of the limiting groove 330 and the limiting block 420 of the connector 400 to keep the unlocking component 300 in the locked position or the unlocked position.

[0043] In Embodiment 2, the unlocking component 300 can rotate circumferentially around the faucet body 100, but its outer wall is provided with either a limiting groove 330 or a limiting block 420. Correspondingly, another component is provided on the connector 400 (i.e., if the unlocking component 300 has a limiting groove 330, then the connector 400 is provided with a limiting block 420, and vice versa), to cooperate with the limiting groove 330 or the limiting block 420 to ensure that the unlocking component 300 can stably stay in the locked or unlocked position.

[0044] The main body of the limiting groove 330 is an axially extending groove structure, which means that the limiting block 420 can move to the end of the limiting groove 330 by moving axially with the unlocking member 300, and then slide into the limiting position 331 of the limiting groove 330 by circumferential movement. When the unlocking member 300 is pushed to the limit position (locked position or unlocked position), the user rotates the unlocking member 300 to make the limiting block 420 slide into the limiting groove 330, thereby locking the unlocking member 300 in that position. The design of the limiting groove 330 and the limiting block 420 ensures that the unlocking member 300 is kept in the locked or unlocked position. This design increases the reliability of the system.

[0045] like Figure 1 , Figure 6 As shown, based on the above embodiment, the buckle 200 is provided with a snap-fit ​​block 220 for fixed connection with the connector 400.

[0046] The snap-fit ​​block 220 is a part specifically designed for secure connection with the connector 400. The snap-fit ​​block 220 can be any suitable shape and size design, with the purpose of ensuring that the snap fastener 200 can be securely installed on the connector 400, and ensuring that the faucet body 100 is connected to the connector 400 via the snap fastener 200.

[0047] like Figure 1 , Figure 3 , Figure 4 , Figure 6 As shown, based on the above embodiment, the buckle 200 is provided with at least two elastic claws 210, the slot 110 is set as an annular groove structure, and the number of top blocks 310 of the unlocking member 300 is the same as the number of elastic claws 210 and they are set one-to-one.

[0048] By setting at least two elastic latches 210 and symmetrically arranging them, the water nozzle body 100 can be better secured, ensuring a reliable connection between the water nozzle body 100 and the latching component 200. The number of top blocks 310 is the same as the number of elastic latches 210, and they are arranged in a one-to-one correspondence. This allows each top block 310 to open its corresponding elastic latch 210, ensuring reliable unlocking.

[0049] like Figures 1 to 7 As shown, a detachable connector assembly includes a water tap and a connector 400. A snap fastener 200 is fixedly connected to the connector 400 via a snap fastener block 220. The water tap body 100 is mated to the connector 400, and the water tap body 100 is fixed to the connector 400 via the snap fastener 200.

[0050] The principle behind the detachable structure of the connector 400 assembly is as follows: Since the snap-fit ​​element 200 is fixedly connected to the connector 400, and the snap-fit ​​element 200 can be detachably connected to the faucet body 100 via the elastic claw 210, the faucet body 100 and connector 400 are detachably connected. When the faucet body 100 and snap-fit ​​element 200 are locked together, the faucet body 100 is precisely aligned with the connector 400. This design simplifies the installation and disassembly process, enabling rapid assembly and disassembly, and facilitating routine maintenance and repair.

[0051] The assembly steps for this connector 400 assembly are as follows: First, connect the snap-fit ​​component 200 to the connector 400. Align the snap-fit ​​block 220 of the snap-fit ​​component 200 with the corresponding snap-fit ​​groove on the connector 400 and tighten it to ensure that the snap-fit ​​component 200 is securely installed on the connector 400. Next, take the faucet body 100 and insert it into the snap-fit ​​component 200, which is already fixed to the connector 400. When the faucet body 100 is fully inserted, the elastic claw 210 on the snap-fit ​​component 200 will automatically engage with the first slot 110 on the faucet body 100, achieving axial locking between the faucet body 100 and the snap-fit ​​component 200. At this time, the faucet body 100 is securely connected to the connector 400 through the snap-fit ​​component 200. Finally, put the unlocking component 300 onto the faucet body 100.

[0052] like Figures 2 to 4 , Figure 6 As shown, based on Embodiment 1, the unlocking member 300 is rotatably connected to the connector 400. The connector 400 is provided with the other of the driving inclined groove 320 and the driving inclined block 410. The driving inclined block 410 is slidably connected to the driving inclined groove 320. When the unlocking member 300 rotates relative to the connector 400, the driving inclined block 410 and the driving inclined groove 320 force the unlocking member 300 to move axially.

[0053] The unlocking member 300 is rotatably connected to the connector 400 and has one of a drive groove 320 or a drive block 410 on its outer wall. Correspondingly, the connector 400 has the other of a drive groove 320 or a drive block 410. The drive block 410 is slidably connected to the drive groove 320 and forms a threaded structure. When the unlocking member 300 rotates, the drive block 410 slides within the drive groove 320. As the unlocking member 300 rotates, the drive block 410 slides along the inclined surface of the drive groove 320. This process converts the rotational motion into linear motion of the unlocking member 300 along the axial direction of the faucet body 100. The axial movement of the unlocking component 300 causes its top block 310 to gradually approach and act on the elastic claw 210 on the latching component 200. During this process, the second inclined surface 311 on the top block 310 contacts the first inclined surface 211 of the elastic claw 210 and applies a radial thrust to make the elastic claw 210 gradually lift up, eventually causing the elastic claw 210 to disengage from the first slot 110 of the faucet body 100 and release the locking state.

[0054] In this embodiment, the rotational motion is converted into axial motion by using a sloping groove and sloping block mechanism, which is more labor-saving than directly pushing the unlocking member 300 axially. Moreover, this design does not require additional space for the direct axial pushing of the unlocking member 300, making it suitable for applications with limited space.

[0055] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, based on Embodiment 2, the unlocking component 300 is rotatably connected to the connector 400. The connector 400 is provided with one of a limiting groove 330 and a limiting block 420. The limiting block 420 is slidably connected to the limiting groove 330. Both ends of the limiting groove 330 have limiting positions 331, and the two limiting positions 331 are located at different positions in the axial direction of the faucet body 100. When the unlocking component 300 is in the locked position, the limiting block 420 is located at one limiting position 331, and when the unlocking component 300 is in the unlocked position, the limiting block 420 is located at the other limiting position 331. When the limiting block 420 is located at the limiting position 331, the unlocking component 300 is restricted from moving along the axial direction of the faucet body 100.

[0056] In this embodiment, the unlocking member 300 can switch between a locked position and an unlocked position, with each position secured by a limiting structure to ensure its stability. The limiting groove 330 is designed as a Z-shaped groove structure, within which the limiting block 420 can slide, allowing the unlocking member 300 to move axially along the faucet body 100. When the unlocking member 300 reaches the locked or unlocked position, by rotating the unlocking member 300, the limiting block 420 can slide into a limiting position 331 within the limiting groove 330. At this point, the unlocking member 300 is firmly fixed in that position and cannot move axially along the faucet body 100. This design ensures the stability and reliability of the unlocking member 300 in both locked and unlocked states.

[0057] The design of the limiting groove 330 and the limiting block 420 ensures that the unlocking part 300 can stay in the locked or unlocked position, avoiding axial movement of the unlocking part 300 due to accidental collisions or other factors.

[0058] like Figures 1 to 6 As shown, compared with Embodiment 2, Embodiment 1 converts rotational motion into axial motion through a slanted groove structure; while Embodiment 2 uses rotational motion to make the limiting block 420 slide into the limiting position 331, thereby playing a role in locking and limiting, ensuring that the unlocking component 300 is stably kept in the unlocked or locked position.

[0059] like Figures 1 to 4 As shown, based on the above embodiment, the faucet body 100 is inserted into the connector 400, and two sealing rings 230 are provided between the faucet body 100 and the connector 400, and an isolation ring 240 is provided between the two sealing rings 230.

[0060] The two sealing rings 230 positioned between the faucet body 100 and the connector 400 provide double protection, ensuring that even if one sealing ring 230 fails, the other sealing ring 230 can still maintain the system's sealing performance. The isolation ring 240 located between the two sealing rings 230 acts as a separator, preventing mutual interference between the two sealing rings 230 and helping to maintain an independent working environment for each sealing ring 230.

[0061] When the system encounters a sudden pressure drop, the dual-seal structure effectively mitigates the impact caused by the pressure drop, ensuring the stress balance of the sealing system through the synergistic action of the two sealing rings 230. Furthermore, if one sealing ring 230 experiences weakened sealing performance or failure due to wear, aging, or other reasons, the other sealing ring 230 can serve as a backup to continue providing sealing protection, ensuring continuous system operation.

[0062] like Figures 1 to 7As shown, a battery system includes a detachable connector assembly 400 and a liquid cooling line 500. The liquid cooling line 500 is connected to the connector 400 via a water nozzle body 100, and a cooling medium can enter the liquid cooling line 500 through the connector 400 and the water nozzle body 100.

[0063] The battery system design integrates a detachable connector 400 assembly and a liquid cooling pipeline 500. The cooling medium flows through the water nozzle body 100 and the connector 400 to ensure that the battery can be effectively cooled during operation.

[0064] The faucet body 100 and the connector 400 can be disassembled or installed by the axial displacement of the unlocking part 300. The disassembly and assembly process can be completed without complicated tools or long operation time, which reduces costs.

[0065] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0066] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0067] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0068] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
