[0026] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed", "provided with", "provided on" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0030] See also Figure 1-4 A liquid cooling plate connection joint tooling comprises a liquid cooling joint 1 and a connector 2, wherein a sealing groove 11 and a limiting groove 12 are provided at the outer end of the liquid cooling joint 1, and the limiting groove 12 is located at the lower side of the sealing groove 11;

[0031] The upper end of the connecting member 2 is fixedly connected with a connecting column 22, and the outer end of the connecting column 22 is provided with a plurality of evenly distributed limiting holes 23, and the limiting holes 23 are movably installed with limiting balls 24 inside, and the limiting balls 24 cooperate with the limiting grooves 12, and the bottom end of the connecting member 2 is fixedly connected with a threaded seat 25;

[0032] The outer end of the connecting column 22 is sleeved with a locking member 3 .

[0033] During use, in order to make the installation between the liquid cooling joint and the interface in the prior art faster and less likely to cause leakage and short circuit of the battery pack circuit, in this embodiment, the connection between the liquid cooling joint and the interface is completed by adopting a chimeric clamping method, and a sealing ring is installed on the inner wall where the joint and the interface contact, so that the two are connected more tightly, which makes it less likely to cause leakage in the future;

[0034] At the same time, when the liquid cooling joint interface is connected, this solution can also monitor whether the joint is leaking, so as to prompt outside personnel, so that personnel can replace the leaking liquid cooling joint in time, avoid the phenomenon of short circuit of the battery pack circuit due to long-term leakage, and improve the protection of the battery pack.

[0035] See also Figure 1-3 The locking member 3 includes a sliding sleeve 34 movably installed at the outer end of the connecting column 22, a spring 31 is installed between the sliding sleeve 34 and the connecting member 2, the spring 31 is sleeved on the surface of the connecting column 22, and a limiting ring 32 is fixedly connected to the inner wall of the locking member 3, and the limiting ring 32 and the limiting ball 24 cooperate with each other.

[0036] When the present solution is in use, the personnel first pulls the sleeve 34 backward, causing the spring 31 to be gradually compressed by the resistance force of the sleeve 34. At this time, the limiting ring 32 also moves backward from the surface of the limiting ball 24, so that the limiting ball 24 on the surface side of the connecting column 22 is no longer compressed. Then the personnel inserts the connecting piece 2 into the surface of the liquid cooling joint 1 until one side of the limiting groove 12 is located below the limiting hole 23, and the limiting ball 24 also falls between the limiting grooves 12 at the same time. At this time, the personnel releases the pulled sleeve 34, and under the reset characteristic of the spring 31, the sleeve 34 gradually returns to its initial state, and the limiting ring 32 presses the limiting ball 24 at the same time, causing the limiting ball 24 to engage in the limiting groove 12, thereby limiting the overall position of the liquid cooling joint 1.

[0037] At the same time, before installing the liquid cooling joint 1, personnel can put a sealing ring on the sealing groove 11, so that when the liquid cooling joint 1 is inserted into the connecting column 22, the sealing ring coincides with the groove on the inner wall of the connecting column 22, further increasing the sealing performance after the overall installation.

[0038] See also Figure 1-4 A water-absorbing pad 33 is embedded in the inner bottom end of the limiting ring 32 , and a warning component 4 is embedded in the outer end of the sliding sleeve 34 at a position corresponding to the water-absorbing pad 33 .

[0039] More specifically, the warning component 4 includes a connecting sleeve 41 embedded in the outer end of the sliding sleeve 34, and a convex hole 42 is opened at the outer end of the connecting sleeve 41. A color-changing pad 43 is installed inside the convex hole 42. The bottom end of the color-changing pad 43 contacts the water-absorbing pad 33, and a folding plate 44 is slidably installed on the side wall of the convex hole 42.

[0040] More specifically, the color-changing pad 43 is made of a water-changing fabric material, and the folding plate 44 is made of a transparent plastic material.

[0041] During use of the present solution, in order to avoid the phenomenon that personnel can quickly judge and monitor whether there is leakage at the joint interface in daily life, in the present embodiment, a water-absorbing pad 33 is embedded inside the limit ring 32. When leakage occurs at the interface joint, the limit hole 23 is the first leakage point to leak outward. At this time, the limit ring 32 is engaged with the limit ball 24 in the limit groove 12, and the water-absorbing pad 33 inside the limit ring 32 first contacts the leaking water. At this time, the water-absorbing pad 33 absorbs the water and conducts it to the color-changing pad 43 embedded in the convex hole 42. The color-changing pad 43 changes color after continuously absorbing water, and under the refraction of the folding plate 44, it is convenient for outside personnel to promptly observe the water leakage at the interface joint so as to promptly repair and replace it.

[0042] And for the convenience of later use, after the color-changing pad 43 changes color after absorbing water, the personnel can replace the color-changing pad 43 by pushing open the folding plate 44, so that it can be used multiple times in the future and the cause of the leakage can be determined.

[0043] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
