Description

Technical Field

[0001] This application relates to the field of automotive parts, and in particular to a connector for a coolant reservoir. Background Technology

[0002] The combustion temperature of the air-fuel mixture in the cylinder of a car engine can reach 2000℃, resulting in very high temperatures for the pistons and cylinders. Therefore, the engine cooling system is particularly important. Engine cooling systems are divided into two types: water-cooled and air-cooled. Water-cooled systems use coolant pipes installed in the cooling system, cooling the engine through heat exchange with the coolant.

[0003] In related technologies, Chinese Patent Publication No. CN219082545U discloses an assembled quick connector, which includes a hollow connector body with both ends connected. The connector body includes a first interface for connecting a cooling water conduit. An elastic ring is coaxially disposed in the connector body with the first interface, and a fixing ring plate is detachably connected to the connector body. The outer peripheral surface of the elastic ring is fitted with the side wall of the fixing ring plate facing the elastic ring.

[0004] Regarding the aforementioned technologies, during long-term circulation, coolant will gradually be consumed due to factors such as high-temperature evaporation and chemical decomposition, resulting in a slow drop in liquid level. The aforementioned assembly quick connectors cannot provide feedback on this normal consumption-induced liquid level change, and often only address the issue after the engine exhibits obvious symptoms of insufficient heat dissipation. There is still room for improvement. Utility Model Content

[0005] To address the issue that existing assembly quick couplings cannot provide feedback on liquid level changes caused by normal cooling water consumption, this application provides a connector for a coolant reservoir.

[0006] The connector for a coolant reservoir provided in this application adopts the following technical solution: A connector for a coolant reservoir includes a hollow connector body with both ends connected, a plug disposed on the connector body and extending into the connector body, and a liquid level sensor disposed at one end of the plug near the connector body, wherein the plug and the liquid level sensor are electrically connected.

[0007] By adopting the above technical solution, when the coolant level drops to a set threshold due to evaporation and consumption, the level sensor can capture the signal in real time and remind the user to add coolant in advance, reducing the probability of waiting until the engine shows symptoms of insufficient heat dissipation before taking action, and ensuring the stable operation of the cooling system.

[0008] Optionally, the connector body is provided with a connecting ring injection molded in the side wall of the connector body, and the connector body is also provided with a bolt that passes through the plug and is threaded onto the connecting ring.

[0009] By adopting the above technical solution, during the pre-embedded injection molding, the molten plastic will tightly wrap the surface of the connecting ring (and even penetrate into the tiny textures on the surface of the metal ring), forming a gapless connection between the "joint body and the connecting ring". Compared with later bonding or snapping, this reduces the probability of loosening or gaps between the connecting ring and the joint body, and further improves the connection reliability between the connecting ring and the joint body.

[0010] Optionally, a toothed ring is integrally provided on the outer peripheral sidewall of the connecting ring.

[0011] By adopting the above technical solution, the plastic fills the gap between the teeth of the toothed ring during injection molding, forming a mechanical interlocking structure that effectively resists the force that drives the connecting ring to rotate when the bolt is tightened, thereby improving the radial stability of the connecting ring fixedly connected to the joint body.

[0012] Optionally, the gear ring is provided with an insert groove, and a portion of the connector body is inserted into the insert groove.

[0013] By adopting the above technical solution, the "plastic protrusion-insertion groove" interlocking structure formed after the plastic is filled into the groove can more effectively prevent the axial displacement of the connecting ring and improve the axial stability of the connecting ring fixedly connected to the joint body.

[0014] Optionally, the connector body is provided with a through hole for the plug and the liquid level sensor to pass through, and the plug is fitted with a plug sealing ring, which abuts against the inner wall of the through hole.

[0015] By adopting the above technical solution, the plug sealing ring is fitted onto the plug and pressed against the inner wall of the through hole, filling the gap between the plug and the hole wall to form a sealing barrier, effectively reducing the probability of coolant leakage, while preventing external dust and impurities from entering the interior of the plug body through the gap, thus improving the sealing performance of the interior space of the plug body.

[0016] Optionally, the outer peripheral sidewall of the connector is provided with a connector ring groove for the connector sealing ring to be embedded.

[0017] By adopting the above technical solution, the insertion ring groove provides a fixed installation space for the insertion sealing ring. The insertion sealing ring is embedded in it, which reduces the probability of axial displacement during the installation and disassembly of the insertion joint and improves the accuracy of the installation position of the insertion sealing ring.

[0018] Optionally, the liquid level sensor is fitted with a sensing sealing ring, and the outer peripheral sidewall of the liquid level sensor is provided with a sensing ring groove for the sensing sealing ring to be embedded.

[0019] By adopting the above technical solution, the induction sealing ring seals the gap between the liquid level sensor and the hole wall of the through hole, the induction ring groove fixes the position of the induction sealing ring, and maintains the sealing effect continuously. The induction sealing ring, together with the plug-in sealing ring, achieves double sealing at the through hole, further improving the sealing performance of the internal space of the connector body.

[0020] Optionally, the chuck body includes a connecting part for connecting to a coolant reservoir and a mounting part for installing a coolant pipe. The mounting part has two symmetrically arranged arc-shaped grooves and an elastic clamping member. The elastic clamping member includes two clamping parts that are respectively embedded in the arc-shaped grooves, a pulling part that connects the two clamping parts, and a limiting part that is respectively fixedly connected to the end of the two clamping parts away from the pulling part. The limiting part abuts against the outer wall of the connector body away from the pulling part. The mounting part has a sealing ring on the side near the connecting part.

[0021] By adopting the above technical solution, the clamping part of the elastic clamping component is embedded in the arc-shaped groove. Pulling the two clamping parts open the cooling water pipe, and then releasing the pulling part, the clamping part springs back to hold the hose tightly, which improves the convenience of installing the cooling water pipe.

[0022] Optionally, the inner wall of the mounting part has several mounting ring grooves, and the mounting sealing ring is partially embedded in the mounting ring groove and fits against the groove wall of the mounting ring groove.

[0023] By adopting the above technical solution, the position of the sealing ring is effectively fixed by installing the ring groove, reducing the displacement of the sealing ring caused by the insertion and removal of the cooling water pipe or long-term vibration, and improving the installation stability of the sealing ring.

[0024] Optionally, the connecting part has an external thread on the side away from the mounting part, and a guide surface is provided at the end of the connecting part away from the mounting part.

[0025] By adopting the above technical solution, the guide surface guides the connecting part to quickly align with the coolant reservoir interface during installation, reducing the difficulty of thread alignment, lowering installation resistance, and effectively improving installation efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application can capture signals in real time through a liquid level sensor, reminding users to add coolant in advance, effectively ensuring the stable operation of the cooling system; 2. The mechanical interlocking structure formed by filling the gap between the teeth of the plastic-filled toothed ring effectively resists the force that drives the connecting ring to rotate, thus improving the radial stability of the connecting ring installed on the joint body. 3. The insertion sealing ring fills the gap between the plug and the wall of the through hole, forming a sealing barrier, which effectively reduces the probability of coolant leakage and improves the sealing performance of the internal space of the plug body.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a connector for a coolant reservoir.

[0034] Reference Figure 1 The connector for the coolant reservoir includes a connector body 1 and a sensing component 2. The sensing component 2 is mounted on the connector body 1 to monitor the liquid level inside the connector body 1 in real time.

[0035] Reference Figure 1 and Figure 2The connector body 1 is hollow and connected at both ends to allow coolant to flow through. The connector body 1 includes an integrally connected connecting portion 11 and a mounting portion 12. The connecting portion 11 has an external thread 111 on the side away from the mounting portion 12 to connect the connecting portion 11 to the coolant reservoir. The end of the connecting portion 11 away from the mounting portion 12 is provided with a guide surface 112 to facilitate aligning the connecting portion 11 and inserting it into the inlet of the coolant reservoir.

[0036] Reference Figure 2 and Figure 3 The mounting portion 12 has an elastic clamping member 121 on the side away from the connecting portion 11 to install the cooling water pipe onto the connector body 1. The elastic clamping member 121 includes a clamping portion 1211, a pulling portion 1212, and a limiting portion 1213. The mounting portion 12 has two symmetrically arranged arc-shaped grooves 122. There are two clamping portions 1211, which are respectively embedded in the two arc-shaped grooves 122. The two ends of the pulling portion 1212 are respectively fixedly connected to the ends of the two clamping portions 1211 to connect the two clamping portions 1211. There are also two limiting portions 1213. The two limiting posts are respectively fixedly connected to the ends of the two clamping portions 1211 away from the pulling portion 1212, and both abut against the outer wall of the mounting portion 12 to prevent the elastic clamping member 121 from falling off from the side near the pulling portion 1212.

[0037] Reference Figure 2 The inner wall of the mounting part 12 has a plurality of mounting ring grooves 123 distributed circumferentially. A mounting sealing ring 124 is arranged on the side of the mounting part 12 near the connecting part 11. The mounting sealing ring 124 is partially embedded in all the mounting ring grooves 123 and fits against the inner wall of the mounting ring grooves 123 to prevent the mounting sealing ring 124 from axially shifting during the installation of the cooling water pipe.

[0038] Reference Figure 2 The sensing component 2 includes a connector 21 and a liquid level sensor 22. A connecting ring 13, injection-molded onto the side wall of the connector body 1, is fixedly connected. A bolt 14 is also arranged on the connector body 1. The bolt 14 passes through the connector 21 and is threaded into the connecting ring 13. The bolt head abuts against the side of the connector 21 away from the connector body 1 to install the connector 21 onto the connector body 1. To prevent the connecting ring 13 from rotating radially when the bolt 14 is tightened, a toothed ring 131 is integrally connected to the outer circumferential side wall of the connecting ring 13, so that a mechanical engagement is formed between the connecting ring 13 and the connector body 1, achieving radial locking. The toothed ring 131 has two recessed grooves 132 distributed axially. The connector body 1 is partially filled into the recessed grooves 132 to achieve axial locking of the connecting ring 13.

[0039] Reference Figure 4The connector body 1 has a through hole 15 for the insertion of the connector 21 and the liquid level sensor 22. The connector 21 has an insertion annular groove 211 on its outer peripheral side wall inside the through hole 15, and an insertion sealing ring 212 is fitted onto the connector 21 at the insertion annular groove 211. The insertion sealing ring 212 is embedded in the insertion annular groove 211 and simultaneously abuts against the bottom of the insertion annular groove 211 and the inner wall of the through hole 15 to achieve a sealed connection between the connector body 1 and the connector 21.

[0040] Reference Figure 4 The liquid level sensor 22 is fixedly connected to one end of the connector 21 near the connector body 1 and is electrically connected to the connector 21 to monitor the water level inside the connector body 1. The outer peripheral sidewall of the liquid level sensor 22 has a sensing ring groove 221, and a sensing sealing ring 222 is fitted onto the sensing ring groove 221. The sensing sealing ring 222 is embedded in the sensing ring groove 221 and simultaneously abuts against the bottom of the sensing ring groove 221 and the inner wall of the through hole 15 to achieve a sealed connection between the connector body 1 and the liquid level sensor 22.

[0041] The implementation principle of a connector for a coolant reservoir according to an embodiment of this application is as follows: the connecting part 11 is threaded to the inlet of the coolant reservoir, and then the clamping part 1211 is pulled open to both sides. After the coolant pipe is inserted into the mounting part 12, the clamping part 1211 is released, and the clamping part 1211 squeezes the coolant pipe to achieve connection. Then the plug 21 is connected to the power supply, and the liquid level sensor 22 is activated to monitor the liquid level.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
