[0032] Embodiment

[0033] Such as Figures 1-9As shown in the figure, a connection device capable of self - adapting to deviation includes a housing 1, a sealing body 2, and a sleeve 3. There are two sets of housings 1. The inner sides of the two sets of housings 1 are connected to the inner wall of the sleeve 3 through the sealing body 2. The sealing body 2 is composed of at least 4 sealing rings 20. At least one sealing ring 20 is installed at both the upper and lower ends of each housing 1. The housing 1 includes a plate body 10 and a connecting part 11. The connecting part 11 penetrates the plate body 10. Moving grooves 12 and fitting grooves 13 are provided at both ends of the connecting part 11. The fitting groove 13 is provided at the outer end of the moving groove 12. A limiting ring 14 is provided between the moving groove 12 and the fitting groove 13. A fixing ring 15 is provided at the outer end of the fitting groove 13. A through - groove 100 is provided on the plate body 10. The sealing ring 20 is made of an elastic material.

[0034] When the sleeve 3 is in a connected state with the housing 1, the inner wall of the sleeve 3 contacts and squeezes the sealing body 2, and the contact surface between the sealing body 2 and the inner wall of the sleeve 3 is compressed and deformed, forming a radial seal between the sealing body 2 and the inner wall of the sleeve 3 to prevent liquid leakage.

[0035] When there is a positional deviation between the central axes of the two sets of housings 1, the contact surface between the sealing body 2 and the sleeve 3 moves, and the sleeve 3 will move or rotate accordingly to automatically absorb this positional deviation and form a radial seal with the inner walls of the housing and the sleeve through the compression deformation of the sealing body to prevent liquid leakage.

[0036] After the housing and the sleeve are connected, they are installed inside the battery pack cooling system. The two ends of the housing and the sleeve are locked by other components. The deviation between the housing and the sleeve is adjusted by the sealing body, and its movement range is small, so the situation of the housing and the sleeve falling off will not occur.

[0037] The connection between the limiting ring 14 and the moving groove 12 is a slope 141. When one side of the sleeve 3 and the housing 1 is inclined, when the inner wall inclination angle of the sleeve 3 is downward, it coincides with the slope 141, avoiding scraping the slope 141 when the inner wall angle is downward, which may cause the inner wall of the sleeve 3 not to be pressed down or scratched.

[0038] The connection between the fixing ring 15 and the inner side of the fitting groove 13 is an arc angle 151. When one side of the sleeve 3 and the housing 1 is inclined, when the inner wall inclination angle of the middle section of the sleeve 3 is downward, it coincides with the arc angle 151, avoiding hard contact between the inner wall of the middle section of the sleeve 3 and the fixing ring 15 when it is inclined, which may cause the fixing ring 15 not to be completely pressed down and easily damage the components.

[0039] The outer side of the sealing ring 20 is an arc 21. When the inner wall of the sleeve 3 contacts and squeezes the sealing body 2, the arc 21 on the outer side of the sealing ring 20 can better seal and fit the inner wall of the sleeve 3. The principle is that the diameter of the arc 21 on the outer side of the sealing ring 20 is slightly larger than the inner diameter of the sleeve 3. When the inner wall of the sleeve 3 is connected to the sealing body 2, the arc 21 on the outer side of the sealing body 2 receives an inward - squeezing force, resulting in a diameter reduction and clamping the inner wall of the sleeve 3, improving the sealing effect. At the same time, the arc 21 on the outer side of the sealing ring 20 is beneficial to the sliding connection between the inner wall of the sleeve 3 and the housing 1.

[0040] On the inner sides at both ends of the sleeve 3, there are provided inclined surfaces 31. The inclined surfaces 31 at both ends of the inner wall of the sleeve 3 can cooperate with the arc 21 on the outer side of the sealing ring 20, so as to avoid directly scratching the sealing ring 20 at the connection positions at both ends of the inner wall of the sleeve 3 when the two components are connected.

[0041] When the sleeve 3 is in a connected state with the housing 1, the inner wall of the sleeve 3 contacts and presses the sealing body 2, and the contact surface between the sealing body 2 and the inner wall of the sleeve 3 is compressed and deformed, so that a radial seal is formed between the sealing body 2 and the inner wall of the sleeve 3 to prevent liquid leakage. When the two groups of housings 1 tilt upward simultaneously, the contact surface between the sealing body 2 and the sleeve 3 moves, and the sleeve 3 remains stationary. One side of the arc 21 on the outer side of the sealing ring 20 fits against the inner wall of the sleeve 3, so as to automatically absorb the position deviation at this position and form a radial seal with the housing and the inner wall of the sleeve through the compression deformation of the sealing body to prevent liquid leakage.

[0042] When the sleeve 3 is in a connected state with the housing 1, the inner wall of the sleeve 3 contacts and presses the sealing body 2, and the contact surface between the sealing body 2 and the inner wall of the sleeve 3 is compressed and deformed, so that a radial seal is formed between the sealing body 2 and the inner wall of the sleeve 3 to prevent liquid leakage. When one of the two groups of housings 1 tilts upward, the contact surface between the sealing body 2 and the sleeve 3 moves, and one end of the sleeve 3 moves towards the housing 1 that tilts upward. One side of the arc 21 on the outer side of the sealing ring 20 fits against the inner wall of the sleeve 3, so as to automatically absorb the position deviation at this position and form a radial seal with the housing and the inner wall of the sleeve through the compression deformation of the sealing body to prevent liquid leakage.

[0043] The above are only the embodiments of the present utility model. Specific structures and common knowledge such as characteristics that are well-known in the art are not described in detail here. Those of ordinary skill in the art know all the common general technical knowledge in the technical field to which the utility model belongs before the application date or the priority date, can know all the prior arts in this field, and have the ability to apply the conventional experimental means before this date. Those of ordinary skill in the art can, under the inspiration given in this application, combine their own abilities to improve and implement this solution. Some typical well-known structures or well-known methods should not become obstacles for those of ordinary skill in the art to implement this application. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent.
