Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to an axial sealing ring with good sealing performance and high reliability. Background Art

[0002] Axial sealing rings are generally made of silicone rubber materials through molding and vulcanization. In new energy vehicle battery boxes and energy storage battery systems, they are often used to adapt to quick-connect water-cooling joints of different pipe diameters to play a sealing role.

[0003] At present, the axial sealing of the water-cooling joint is mainly achieved by the frictional contact between the cylindrical inner wall of the sealing ring and the outer wall of the joint, and the sealing between the flange and the box frame. Theoretically, the contact area between this structure and the water-cooling joint is large, but during the assembly process, improper axial assembly can easily produce wrinkles and gaps, causing leakage.

[0004] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Utility Model Content

[0005] The purpose of the utility model is to redesign the structure of the existing sealing ring to avoid wrinkles and gaps caused by improper assembly and thus solve the above-mentioned shortcomings in the technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an axial sealing ring with good sealing performance and high reliability, used for axial sealing of the mounting hole of the water-cooling joint on the box frame, comprising a sleeve sleeved outside the water-cooling joint, and a flange formed by integrating the end of the sleeve, wherein the outer peripheral surface of the sleeve near one end of the flange is provided with a circle of inwardly recessed recessed ring, the portion of the sleeve with the recessed ring forms a deformation portion, and the portion without the recessed ring forms a sealing portion;

[0007] When the central axis of the water-cooling joint does not coincide with the central axis of the mounting hole, the deformation portion bends and deforms, and the inner circumference of the sealing portion and the flange sheet fits with the outer circumference of the water-cooling joint.

[0008] Preferably, the width of the recessed ring is greater than the length of the mounting hole, and when the deformable portion does not bend, the sealing portion does not contact the outer wall of the box frame;

[0009] The width of the recessed ring is greater than the length of the mounting hole, and a space margin is provided for the bending deformation of the deformable portion.

[0010] Preferably, the outer diameter of the deformation portion is smaller than the inner diameter of the mounting hole;

[0011] The convenient deformation portion is deformed.

[0012] Preferably, the cross-sectional shape of the recessed ring is overall set to be U-shaped, V-shaped, gate-shaped or semicircular.

[0013] Preferably, the inner diameters of the flange, the deformation portion and the sealing portion are the same, and are all interference fit with the water cooling joint;

[0014] The interference fit helps to ensure a tight seal when the water cooling joint is installed.

[0015] Preferably, the flange has a compression of more than 30% when under pressure;

[0016] The sealing ring flange position is designed to retain 30% compression, and a pressing force is applied to the box frame through the pressing block, which can provide a double sealing effect for the box.

[0017] Preferably, both ends of the outer peripheral surface of the deformation portion have rounded transitions at the connection points with the sealing portion and the flange.

[0018] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0019] 1. This product uses the bending deformation of the deformation part to ensure that the sealing part and the flange are tightly wrapped outside the water-cooling joint, so that the central axis of the sealing part and the flange coincides with the central axis of the water-cooling joint, avoiding the problem of wrinkles and gaps caused by improper assembly.

[0020] 2. This product has a simple structure. This function can be achieved by simply opening a recessed ring on the existing product, which is easy to upgrade the product and reduces the expenditure on production materials;

[0021] 3. The design of the sealing ring flange position retains 30% of the compression amount, and the existing pressure block is used to give a pressing force to the box frame, while providing a double sealing effect to the box frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Example:

[0032] like Figure 1-Figure 3 As shown, an axial seal for a mounting hole of a water-cooling joint on a box frame comprises a sleeve 1 sleeved outside the water-cooling joint, and a flange 2 integrally formed at the end of the sleeve 1, an outer peripheral surface of the sleeve 1 close to one end of the flange 2 is provided with a circle of inwardly recessed recessed ring 3, the cross-sectional shape of the recessed ring 3 is overall set to be U-shaped, V-shaped, gate-shaped or semicircular, the portion of the sleeve 1 having the recessed ring 3 forms a deformation portion 101, and the portion without the recessed ring 3 forms a sealing portion 102, the width of the recessed ring 3 is greater than the length of the mounting hole, when the deformation portion 101 is bent and deformed, the sealing portion 102 does not contact the outer wall of the box frame, the outer diameter of the deformation portion 101 is smaller than the inner diameter of the mounting hole, the inner diameters of the flange 2, the deformation portion 101 and the sealing portion 102 are the same, and all are interference fit with the water-cooling joint.

[0033] When the sealing ring is installed on the mounting hole of the box frame, insert the water cooling joint into the sleeve 1 and the flange 2, and install it in the sleeve 1 and the flange 2 by interference fit. If the center axis of the water cooling joint does not coincide with the center axis of the mounting hole, Figure 1For example, if the water-cooling joint is deflected clockwise, the sealing part 102 and the flange 2 will be wrapped around the outside of the water-cooling joint, ensuring that the central axis of the sealing part 102 and the flange 2 coincides with the central axis of the water-cooling joint, and the width between the upper part of the deformation part 101 will increase, and the left side wall of the lower part of the deformation part 101 will be close to the side wall of the box frame. By utilizing the bending deformation of the deformation part 101, the flange 2 on the inner side of the box frame and the sleeve 1 on the outer side form a relatively independent part, ensuring that the sealing part 102 and the flange 2 are tightly wrapped around the outside of the water-cooling joint, avoiding wrinkles and gaps caused by improper assembly and causing leakage.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
