[0025] The above technical solution has the following advantages or beneficial effects:
[0026] The blind-mating fluid connector provided by this utility model includes a male end connection assembly, which includes a male end valve core. When the coolant flows in the fluid connector, it flows from the male end connection assembly to the female end connection assembly. At this time, the coolant needs to flow through the male end valve core. If the contact area between the male end valve core and the coolant is too large, the male end valve core will obstruct part of the coolant flow, causing the coolant to form a vortex, thereby reducing the coolant flow rate. Therefore, the male end valve core is made into a conical shape, with the tip of the cone facing the flow direction of the coolant. This effectively reduces the instantaneous contact area between the coolant and the male end valve core when the coolant contacts the male end valve core, thereby reducing the flow resistance.
[0027] Furthermore, even with a reduced instantaneous contact area between the coolant and the male valve core, the coolant still flows forward and contacts the conical surface of the male valve core, generating significant flow resistance. Therefore, the conical generatrix of the male valve core includes both convex and concave arcs, with the concave and convex arcs smoothly connected. If the male valve core is vertically positioned, the rotating body formed by the concave arc is located at the top of the male valve core, and the rotating body formed by the convex arc is located at the bottom of the male valve core, thus streamlining the conical generatrix of the male valve core. The end where the male end connector and the female end connector are connected is the inner end. The side of the male end valve core with the concave arc rotating body faces the outer end of the male end connector and is directly opposite to the flow direction of the coolant. The streamlined structure can avoid the sudden change in the direction of fluid velocity when the coolant comes into contact with the male end valve core, so that the coolant can flow in accordance with the curved surface of the male end valve core, delaying the separation position of the coolant close to the curved surface of the male end valve core from the male end valve core, thereby reducing eddies, reducing flow resistance, and thus increasing the flow rate of coolant in the fluid connector.
[0028] Furthermore, it also includes several flow divider brackets. All flow divider brackets are evenly distributed along the edge of the male valve core. The flow divider brackets are fixed to the male valve core and abut against the inner wall of the male valve sleeve. The flow divider brackets evenly divide the gap between the male valve core and the male valve sleeve to form several coolant channels. When the coolant passes through the coolant channels, the coolant is diverted to avoid coolant accumulation, further reduce eddies, and increase the coolant flow rate.
[0029] Existing technologies use male valve cores with sharp edges, which easily form eddies when the coolant passes through the male valve core, thereby reducing the coolant flow rate. The blind-mating fluid connector provided by this utility model, by designing the male valve core as a cone shape, adopting a streamlined structure for the conical generatrix of the male valve core, and adding a flow divider bracket around the male valve core, can reduce eddies, lower flow resistance, and thus increase the coolant flow rate in the fluid connector.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.
[0036] Example 1:
[0037] like Figures 1-3 As shown, Embodiment 1 of this utility model provides a blind-mating fluid connector, including a male end connection component 1 and a female end connection component 2; the male end connection component 1 includes a male end valve seat 11, a male end valve sleeve 12 and a male end valve core 13; the female end connection component 2 includes a female end valve seat 21, a female end valve sleeve 22 and a female end valve core 23;
[0038] The male valve seat 11 has a first channel 111 extending through both ends; the male valve sleeve 12 floats radially within the first channel 111; the male valve core 13 slides within the male valve sleeve 12; the female valve seat 21 has a second channel 211 extending through both ends; the female valve sleeve 22 slides within the second channel 211; the female valve core 23 is fixed to the female valve seat 21; the female valve core 23 is located within the female valve sleeve 22.
[0039] The male valve core 13 is conical; the generatrix of the male valve core 13 includes an outwardly convex arc 01 and an inwardly concave arc 02; the inwardly concave arc 02 and the outwardly convex arc 01 are smoothly connected; if the male valve core 13 is vertically installed, the rotating body formed by the inwardly concave arc 02 is located at the top of the male valve core 13, and the rotating body formed by the outwardly convex arc 01 is located at the bottom of the male valve core 13.
[0040] The end where the male end connection component 1 and the female end connection component 2 are connected is taken as the inner end, and the side of the male end valve core 13 with the concave arc 02 rotating body faces the outer end of the male end connection component 1.
[0041] It also includes several diversion brackets 14; all diversion brackets 14 are evenly distributed along the edge of the male valve core 13; the diversion brackets 14 are fixed to the male valve core 13; the diversion brackets 14 abut against the inner wall of the male valve sleeve 12.
[0042] When using the blind-mating fluid connector provided in Embodiment 1 of this utility model, the outer end of the male valve seat 11 and the outer end of the female valve seat 21 are connected to the inlet and outlet of the coolant, respectively.
[0043] When the male end connecting assembly 1 and the female end connecting assembly 2 are connected, the inner end of the male end valve seat 11 is in contact with the inner end of the female end valve seat 21; the male end valve sleeve 12 is inserted into the second channel 211, and the male end valve sleeve 12 squeezes the female end valve sleeve 22, causing the female end valve sleeve 22 to slide towards the outer end of the female end valve seat 21. At this time, there is a gap between the female end valve sleeve 22 and the female end valve core 23, which is the first gap; the female end valve core 23 is inserted into the second channel 211, and the female end valve core 23 squeezes the male end valve core 13, causing the male end valve core 13 to slide towards the outer end of the male end valve seat 11. At this time, there is a gap between the male end valve sleeve 12 and the male end valve core 13, which is the second gap; coolant flows in from the male end valve sleeve 12, passes through the second gap, and because the male end valve sleeve 12 is inserted into the second channel 211, the first channel 111 and the second channel 211 are connected, thus the first gap and the second gap are connected, and coolant enters the first gap from the second gap and finally flows out from the female end valve sleeve 22;
[0044] When the male end connection assembly 1 and the female end connection assembly 2 are separated, the female end valve core 23 leaves the first channel 111, and the male end valve core 13 slides to the inner end of the male end valve sleeve 12, sealing the inner port of the male end valve sleeve 12; at the same time, the male end valve sleeve 12 leaves the second channel 211, and the female end valve sleeve 22 slides to be flush with the inner end of the female end valve core 23, sealing the inner port of the female end valve sleeve 22; by sealing the inner ports of the male end valve sleeve 12 and the female end valve sleeve 22 respectively, the coolant flowing between the male end connection assembly 1 and the female end connection assembly 2 is cut off.
[0045] The blind-mating fluid connector provided in Embodiment 1 of this utility model includes a male end connection component 1, which includes a male end valve core 13. When the coolant flows in the fluid connector, it flows from the male end connection component 1 to the female end connection component 2. At this time, the coolant needs to flow through the male end valve core 13. If the contact area between the male end valve core 13 and the coolant is too large, the male end valve core 13 will obstruct part of the coolant flow, causing the coolant to form a vortex, thereby reducing the flow rate of the coolant. Therefore, the male end valve core 13 is made into a conical shape, with the tip of the cone facing the flow direction of the coolant. When the coolant contacts the male end valve core 13, the instantaneous contact area between the coolant and the male end valve core 13 can be effectively reduced, thereby reducing the flow resistance.
[0046] Furthermore, even if the instantaneous contact area between the coolant and the male valve core 13 is reduced, the coolant still flows forward and contacts the conical surface of the male valve core 13, generating significant flow resistance. Therefore, the conical generatrix of the male valve core 13 includes an outwardly convex arc 01 and an inwardly concave arc 02, with the inwardly concave arc 02 smoothly connected to the outwardly convex arc 01. If the male valve core 13 is vertically positioned, the rotating body formed by the inwardly concave arc 02 is located at the top of the male valve core 13, and the rotating body formed by the outwardly convex arc 01 is located at the bottom of the male valve core 13, thus forming the conical generatrix of the male valve core 13... The streamlined design features one end connecting the male connector 1 and the female connector 2 as the inner end. The male valve core 13 has a side with a concave arc 02 rotating body facing the outer end of the male connector 1, directly opposite the flow direction of the coolant. The streamlined structure can prevent abrupt changes in the fluid velocity direction when the coolant comes into contact with the male valve core 13, allowing the coolant to flow in accordance with the curved surface of the male valve core 13. This delays the separation of the coolant close to the curved surface of the male valve core 13 from the male valve core 13, thereby reducing eddies, lowering flow resistance, and increasing the flow rate of the coolant in the fluid connector.
[0047] Furthermore, it also includes several diversion brackets 14, all of which are evenly distributed along the edge of the male valve core 13. The diversion brackets 14 are fixed to the male valve core 13 and abut against the inner wall of the male valve sleeve 12. The diversion brackets 14 evenly divide the gap between the male valve core 13 and the male valve sleeve 12 to form several coolant channels. When the coolant passes through the coolant channels, the coolant is diverted to avoid coolant accumulation, further reduce eddies, and increase the flow rate of the coolant.
[0048] Existing technologies use male valve cores with sharp edges, which easily form eddies when the coolant passes through the male valve core, thereby reducing the coolant flow rate. The blind-mating fluid connector provided in Embodiment 1 of this utility model, by designing the male valve core 13 as a cone shape, adopting a streamlined structure for the conical generatrix of the male valve core 13, and adding a flow divider bracket 14 around the male valve core 13, can reduce eddies, lower flow resistance, and thus increase the coolant flow rate in the fluid connector.
[0049] like Figure 1 As shown, the blind-mating fluid connector provided in Embodiment 1 of this utility model preferably has a rounded top end of the male valve core 13, so that the rounded side of the male valve core 13 faces the outer end of the male connection assembly 1. The rounded top end structure is closer to a streamlined shape. When in contact with the coolant, the rounded top end, through the smooth transition of the curved surface, reduces the gap between the coolant that was originally close to the surface of the male valve core 13 and the surface of the male valve core 13, delaying the separation position of the coolant and the male valve core 13, thereby reducing eddies. At the same time, the rounded top end can make the coolant velocity change more gradual, reducing the conditions for eddy formation.
[0050] like Figure 1 and Figure 3 As shown, the blind-mating fluid connector provided in Embodiment 1 of this utility model is preferably designed to allow the male valve core 13 to slide within the male valve sleeve 12. Specifically, the male connection assembly 1 further includes a male spring 15 and a male spring seat 16. When the male connection assembly 1 and the female connection assembly 2 are separated, the male valve core 13 is controlled by the male spring 15 to slide to the inner end of the male valve sleeve 12.
[0051] To fix the male end spring 15, the male end spring seat 16 includes a first ring 161 and a plurality of limiting blocks 162, the limiting blocks 162 being distributed along the inner circular sidewall of the first ring 161; the outer circular sidewall of the first ring 161 is fixed to the sidewall of the first channel 111, located at the outer end of the first channel 111, the male end spring 15 is located inside the male end valve sleeve 12, one end of the male end spring 15 is in contact with the diverter bracket 14, and the other end is in contact with the limiting block 162;
[0052] Furthermore, by using the limiting block 162 to contact and fix the male end spring 15, the center space of the male end spring seat 16 can be reserved. When the coolant passes through the male end spring seat 16, the coolant can flow in from the center space of the male end spring seat 16, reducing the obstruction effect of the male end spring seat 16 on the coolant, thereby increasing the flow rate of the coolant in the fluid connector. Furthermore, by contacting the male end spring 15 with the flow divider bracket 14, compared to contacting the male end spring 15 directly with the male end valve core 13, the flow resistance of the male end spring 15 on the coolant flow can be avoided.
[0053] like Figures 1-3As shown, the blind-mating fluid connector provided in Embodiment 1 of this utility model preferably includes a diversion block 14 and a sliding block 142 in order to realize the diversion function of the diversion bracket 14 and provide sliding capability for the male valve core 13. One end of the diversion block 141 is fixed to the curved side wall of the male valve core 13, and the other end is fixed to the sliding block 142. The end of the sliding block 142 fixed to the diversion block 141 is the proximal end of the sliding block 142, and the other end is the distal end of the sliding block 142. The distal end surface of the sliding block 142 is an arc surface. The arc surface of the sliding block 142 is in contact with the inner wall of the male valve sleeve 12, thereby avoiding collision between the male valve core 13 and the inner wall of the male valve sleeve 12 when sliding, extending the service life of the fluid connector. At the same time, the two diversion blocks 141 and the inner wall of the male valve sleeve 12 form a coolant channel for diverting coolant.
[0054] In this structure, the male end spring 15 is in contact with the near end face of the sliding block 142 and with the diverter block 141.
[0055] like Figure 1 and Figure 4 As shown, the blind-mating fluid connector provided in Embodiment 1 of this utility model, preferably, in order to further improve the flow rate of coolant in the fluid connector, specifically, the female valve core 23 includes a contact portion 231, a connecting portion 232, and a fixing portion 233. The contact portion 231 and the fixing portion 233 are both disc-shaped, and the connecting portion 232 is cylindrical. The axis of the connecting portion 232, the axis of the contact portion 231, and the axis of the fixing portion 233 are coincident, so that the gap between the female valve core 23 and the female valve sleeve 22 is uniform, reducing the eddies generated when the coolant flows.
[0056] Furthermore, the circular edges of adjacent contact portions 231 and the circular edges of connecting portions 232 are connected by curved surfaces, and the cross-section of the female valve core 23 gradually decreases from the contact portion 231 to the connecting portion 232; the circular edges of adjacent connecting portions 232 and the circular edges of fixing portions 233 are connected by curved surfaces, and the cross-section of the female valve core 23 gradually increases from the connecting portion 232 to the fixing portion 233; the arc of the female valve core 23 forms a streamlined structure, which can further reduce eddies, reduce flow resistance, and thus increase the flow rate of coolant in the fluid connector;
[0057] In order to allow coolant to be discharged from the female end connecting assembly 2, a plurality of through holes 2331 are provided on the fixing part 233, and the side wall of the fixing part 233 is fixed to the side wall of the second channel 211.
[0058] like Figure 1As shown, in order to enable the female valve sleeve 22 to slide in the second channel 211, the inner sidewall of the female valve sleeve 22 is provided with a first extension 221, the first extension 221 extends in the direction of the axis of the female valve sleeve 22, and a limiting groove 2211 is provided on the outer end face of the first extension 221.
[0059] The female end connection assembly 2 also includes a female end spring 24; the female end spring 24 is located inside the female end valve sleeve 22; one end of the female end spring 24 is in contact with the fixing part 233, and the other end is embedded in the limiting groove 2211;
[0060] When the male end connection component 1 and the female end connection component 2 are separated, the female end spring 24 controls the female end valve sleeve 22 to slide to the level of the inner end of the female end valve core 23.
[0061] Furthermore, by opening a limiting groove 2211 on the outer end face of the first extension 221, compared to directly setting the female end spring 24 between the female end valve sleeve 22 and the fixing part 233, the installation space of the female end spring 24 can be effectively saved, thereby facilitating the installation of the fluid connector in a narrow space and reducing the production cost of the fluid connector.
[0062] like Figure 1 As shown, the blind-mating fluid connector provided in Embodiment 1 of this utility model, preferably, in order to achieve radial floating of the male end valve sleeve 12 within the first channel 111, specifically, the male end valve seat 112 includes a first valve seat 1121 and a second valve seat 1122; the first valve seat 1121 is annular; the second valve seat 1122 includes a second ring 11221 and a third ring 11222; the outer circular sidewall of the second ring 11221 is fixed to the inner circular sidewall of the third ring 11222; the outer circular sidewall of the first valve seat 1121 and the inner circular sidewall of the third ring 11222 are detachably fixed; there is a gap between the second ring 11221 and the first valve seat 1121; the second ring 11221, the third ring 11222, and the first valve seat 1121 constitute a floating groove 1120;
[0063] The outer side wall of the male end valve sleeve 12 is provided with a second extension 121; taking the direction away from the axis of the male end valve sleeve 12 as the outward direction, the second extension 121 extends outward; the second extension 121 is located in the floating groove 1120; the second extension 121 is radially floatingly disposed in the floating groove 1120.
[0064] Since the second extension 121 needs to be fitted into the floating groove 1120, it cannot be directly assembled into the floating groove 1120. In order to facilitate the placement of the male valve sleeve 12 into the floating groove 1120, the outer circular sidewall of the first valve seat 1121 and the inner circular sidewall of the third ring 11222 are detachably fixed. During assembly, the male valve sleeve 12 is first fitted into the second valve seat 1122, the second extension 121 is abutted against the second ring 11221, and then the first valve seat 1121 is fixed to the third ring 11222. Specifically, the first valve seat 1121 and the third ring 11222 are connected by threads.
[0065] like Figure 1 As shown, in the blind-mating fluid connector provided in Embodiment 1 of this utility model, preferably, since the male valve sleeve 12 is floating, it is not conducive to the insertion of the male valve sleeve 12 into the female valve seat 21. Therefore, the inner end of the female valve seat 21 is provided with a guide member 212; the guide member 212 is provided with a guide hole 2121 through it, and the guide hole 2121 is connected to the second channel 211. The cross-section of the guide hole 2121 gradually decreases from the inner end to the outer end. When the male valve sleeve 12 is inserted into the female valve seat 21, the inner end of the male valve sleeve 12 first passes through the inner end of the guide hole 2121 and moves to the outer end. Since the cross-section of the guide hole 2121 gradually decreases from the inner end to the outer end, the larger space at the inner end of the guide hole 2121 facilitates the adjustment of the insertion position of the male valve sleeve 12. The gradually decreasing space plays a guiding role in the insertion of the male valve sleeve 12.
[0066] like Figure 1 As shown, in the blind-mating fluid connector provided in Embodiment 1 of this utility model, preferably, a first annular groove 131 is provided on the male valve core 13, and a second annular groove 2311 is provided on the contact portion 231; O-rings are embedded in the first annular groove 131 and the second annular groove 2311; by setting the O-rings, when the male end connecting assembly 1 and the female end connecting assembly 2 are separated, the O-rings can prevent leakage caused by a gap between the male end valve core 13 and the male end valve sleeve 12, and similarly, can prevent leakage caused by a gap between the female end valve core 23 and the female end valve sleeve 22.

When the second extension 121 floats in the floating groove 1120, the rolling ball 12110 can reduce the friction between the second extension 121 and the floating groove 1120, thereby making the floating adjustment of the male end valve sleeve 12 more flexible.
[0069] like Figures 3-4 As shown, in the blind-mating fluid connector provided in Embodiment 1 of this utility model, preferably, in order to connect the inlet and outlet of the coolant, flanges 03 are provided at the outer ends of the male valve seat 11 and the female valve seat 21.
[0070] Specifically, flange 03, male valve seat 11 and male spring seat 16 form a fifth annular groove 04 on the outer end face of male valve seat 11. An O-ring is embedded in the fifth annular groove 04 to prevent leakage at the connection between the coolant inlet and male valve seat 11.
[0071] The fixing part 233 of flange 03, female valve seat 21 and female valve core 23 forms a sixth annular groove 05 on the outer end face of female valve seat 21. An O-ring is embedded in the sixth annular groove 05 to prevent leakage at the connection between the coolant outlet and female valve seat 21.
[0072] In summary, the blind-mating fluid connector provided by this utility model can solve the problem in the prior art where the irregular male end obstructs part of the coolant flow, causing the coolant to form vortices and thus reducing the coolant flow rate; thereby increasing the coolant flow rate in the fluid connector.
