Description

Technical Field

[0001] The utility model relates to the technical field of installation of automobile equipment and expansion water tank electronic devices, and in particular to an installation structure of a liquid level sensor of an expansion water tank. Background Art

[0002] The information disclosed in the background technology of the present invention is only intended to increase the understanding of the overall background of the present invention, and shall not necessarily be regarded as an admission or suggestion in any form that the information constitutes the prior art already known to those skilled in the art.

[0003] The liquid level sensor on the expansion tank is used to detect the liquid level in the expansion tank to ensure stable operation of the system. The traditional clip-on installation structure is generally installed through the installation hole, and then inserted into the side clip-on structure to limit the installation. This installation method is not stable enough and is easy to loosen. Moreover, the clip-on structure is easy to deform after long-term use, which affects the reliability of the liquid level sensor installation.

[0004] In addition, due to the poor stability and sealing of the traditional installation method, the liquid level sensor can only be installed at a specific position on the upper box cover, which limits the installation flexibility and applicability of the liquid level sensor. Therefore, it is necessary to study a liquid level sensor installation structure with better stability and sealing. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a liquid level sensor installation structure for an expansion water tank, aiming to improve the stability and reliability of the installation of the liquid level sensor on the expansion water tank, thereby improving the flexibility and applicability of the installation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A liquid level sensor mounting structure for an expansion water tank comprises a mounting hole, and a mounting seat is arranged outside the mounting hole;

[0008] The mounting seat comprises more than two arc-surface buckles, which are arranged at equal distances with the mounting hole as the center, and an arc-shaped clamping platform is provided on the inner side of each arc-surface buckle, and a limiting groove is provided between two adjacent arc-surface buckles;

[0009] The liquid level sensor is provided with an arc-shaped card slot adapted to the arc-shaped card platform, and the arc-shaped card slot is provided with two or more card blocks corresponding to the limit slot;

[0010] A sealing ring is sleeved on the outer side of one end of the detection body of the liquid level sensor close to the arc-shaped slot.

[0011] Preferably, an arc-shaped inclined surface cavity is arranged at the lower side of the arc-shaped card platform, and a matching end adapted to the arc-shaped inclined surface cavity is arranged at the lower side of the arc-shaped card slot.

[0012] Preferably, the sealing ring is sleeved on the lower side of the mating end;

[0013] The sealing ring includes an axial sealing portion located at an upper side and a radial sealing portion located at a lower side.

[0014] Preferably, a circular step for installing the sealing ring is provided at the top of the mounting hole.

[0015] Preferably, the arc-surface buckle comprises a buckle body and a skirt.

[0016] Preferably, the arc-shaped clamping platform is arranged inside the buckle body;

[0017] Preferably, the arc-shaped inclined cavity is arranged on the inner side wall of the circular step on the lower side of the skirt.

[0018] Preferably, 3 to 5 arc-surface buckles are provided.

[0019] Preferably, an auxiliary mounting sleeve adapted to the detection body is provided below the mounting hole.

[0020] The utility model includes but is not limited to the following beneficial effects:

[0021] In the utility model, by setting more than two arc-surface buckles, multiple contact points are formed to fix the liquid level sensor. Compared with the traditional single-point clamping, this multi-point fixation can significantly increase the stability of sensor installation and reduce looseness caused by vibration or external factors. The arc-surface buckle can provide better strength and rigidity, ensuring that the buckle structure is not easily deformed and can maintain good installation performance even after long-term use. The multi-point fixing mechanism combined with the strength and rigidity provided by the arc surface enhances the stability and reliability of the liquid level sensor installation.

[0022] In the utility model, the sealing ring sleeved on the outer side of the detection body of the liquid level sensor, combined with the circular ring step at the top of the mounting hole, can provide sealing in both axial and radial directions, greatly enhancing the sealing effect between the sensor and the expansion water tank.

[0023] Through stable and reliable installation and good sealing, the liquid level sensor can be installed not only on the upper tank cover of the expansion water tank, but also on the side or even the bottom of the lower tank body, which greatly increases the flexibility of installation and is suitable for more types of expansion water tanks and installation scenarios.

[0029] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] Figures 1 to 3 A mounting structure of a liquid level sensor 5 of an expansion water tank is shown, so that the liquid level sensor 5 can be mounted on the upper tank cover 1 of the expansion water tank, or on the side of the lower tank body or even on the bottom of the lower tank body, and can be selected according to the specific installation scenario; specifically, it includes a mounting hole, and a mounting seat is arranged outside the mounting hole;

[0031] The mounting seat includes more than two arc-surface buckles 2, preferably 3 to 5, and 4 in the present embodiment, and the liquid level sensor 5 is fixed by multiple contact points to increase stability. The arc-surface buckle 2 has excellent strength and rigidity for plastic materials, and can provide a more stable and reliable buckle installation. The arc-surface buckles 2 are arranged at equal distances with the mounting hole as the center, that is, arranged in a circle. An arc-shaped clamping platform is provided on the inner side of each arc-surface buckle 2, and a limit groove 3 is provided between two adjacent arc-surface buckles 2;

[0032] The liquid level sensor 5 is provided with an arc-shaped card slot 53 adapted to the arc-shaped card platform, which is used to clamp the axial direction of the liquid level sensor 5. Since the arc-shaped buckles are evenly arranged and are arranged at equal distances with the mounting hole as the center, a more uniform limit can be provided in the horizontal plane where the limit surface is located, so that the installation of the liquid level sensor 5 is more stable and reliable, laying a foundation for good sealing; the arc-shaped card slot 53 is provided with more than two card blocks 52 corresponding to the limit slot 3, which are used to clamp the rotation direction of the liquid level sensor 5;

[0033] A sealing ring 6 is sleeved on the outer side of one end of the detection body 51 of the liquid level sensor 5 close to the arc-shaped slot 53. On the basis of stable installation, the sealing ring 6 is combined to provide good sealing for the installation of the liquid level sensor 5, allowing the sensor to be installed at different positions of the expansion tank, thereby improving the flexibility and applicability of the installation of the liquid level sensor 5.

[0034] An arc-shaped inclined surface cavity is arranged at the lower side of the arc-shaped card platform, and a mating end 54 adapted to the arc-shaped inclined surface cavity is arranged at the lower side of the arc-shaped card slot 53. The mating end 54 and the arc-shaped inclined surface cavity cooperate so that when the liquid level sensor 5 is installed, the liquid level sensor 5 gradually deforms as it is installed to perform a sealed installation, and an upward component force can also be provided during disassembly, which is conducive to disassembly.

[0035] Specifically, the sealing ring 6 is sleeved on the lower side of the mating end 54; the sealing ring 6 includes an axial sealing portion located on the upper side and a radial sealing portion located on the lower side; accordingly, a circular step for installing the sealing ring 6 is provided at the top of the mounting hole, which can perform sealing from both the axial end and radial angles, thereby improving the sealing effect.

[0036] The arc-surface buckle 2 includes a buckle body 21 and a skirt 22 . The skirt 22 is used to improve the strength, stability and toughness of the arc-surface buckle 2 , thereby improving the installation reliability of the liquid level sensor 5 .

[0037] Specifically, the arc-shaped clamping platform is arranged on the inner side of the buckle body 21 ; and the arc-shaped inclined cavity is arranged on the inner side wall of the circular step on the lower side of the skirt 22 .

[0038] An auxiliary installation sleeve 4 adapted to the detection body 51 is provided below the installation hole to prevent the liquid level sensor 5 from damaging the installation mating surface and the sealing surface due to large-scale swinging, thereby further enhancing the reliability of the installation of the liquid level sensor 5.

[0039] In summary, the installation structure of the liquid level sensor 5 of the expansion water tank effectively solves the problems existing in the installation structure of the traditional expansion water tank liquid level sensor 5, improves the stability and sealing of the sensor, and increases the flexibility and applicability of the installation.
