[0073] Please see Figure 1 and Figure 2 . Figure 1This is a three-dimensional schematic diagram of the floating connection device of this utility model from one perspective. Figure 2 This is a three-dimensional schematic diagram of the floating connection device of this utility model from another perspective.
[0074] A floating connection device 1 according to this embodiment includes: a guide pin 11, a guide component 12, and a floating component 13. One end of the guide pin 11 has a floating male connector M. The guide component 12 is sleeved on the guide pin 11. The floating component 13 is sleeved on the guide pin 11 and abuts against the guide component 12. The floating component 13 causes the guide pin 11 to move under the drive of the guide component 12 so that the floating male connector M docks with a female connector F.
[0075] This invention uses the cooperation of the floating component 13 and the guide component 12 to ensure that the guide pin 11 can move in the X, Y and Z directions during docking, thereby ensuring accurate docking of the floating male connector M and the female connector F. At the same time, even if the assembly position is incorrect, it can be correctly aligned by the synchronous correction of the guide component 12, reducing the friction between the floating male connector M and the female connector F.
[0076] Please see Figures 3-8 , Figure 3 for Figure 1 An exploded view of the floating connection device. Figure 4 This is a cross-sectional view of the floating connection device of this utility model from one perspective. Figure 5 This is a cross-sectional view of the floating connection device of this utility model from another perspective. Figure 6 This is a schematic diagram of the floating connection device of this utility model in the X and Y directions. Figure 7 This is a schematic diagram of the floating connection device of this utility model in the Z direction. Figure 8 This is a schematic diagram of the shell structure of this utility model.
[0077] like Figure 3-8 As shown, the guide pin 11 has a head 11, a middle part 12, and a tail 13 connected in sequence, and the head 11 has the floating male connector M. The guide assembly 12 includes a guide rod 121 and a guide member 122. The guide member 122 is connected to the guide rod 121. The guide rod 121 is parallel to the axial direction of the guide pin 11. The guide member 122 has a first through hole K1, which is sleeved on the middle part 12 and located near the head 11.
[0078] Further, the floating component 13 includes: a housing 131 and an elastic member 132. The housing 131 has an accommodating space S inside. The guide pin 11 passes through the housing 131 so that the middle part 112 is located in the accommodating space S. The elastic member 132 is disposed in the accommodating space S. One end of the elastic member 132 abuts against the housing 131, and the other end of the elastic member 132 abuts against the guide member 122. The elastic member 132 enables the guide member 122 to move along the axial direction of the elastic member 132, that is, the guide member 122 can move along the Z direction.
[0079] It should be noted that, in this embodiment, the guide member 122 is movable by 2 mm along the axial direction of the elastic member 132, which is a preferred implementation.
[0080] Furthermore, the floating assembly 13 further includes: a pressure plate 133 and two rollers 134. The pressure plate 133 is sleeved on the elastic member 132. The two rollers 134 are spaced apart from the pressure plate 133 and abut against the side of the guide member 122 facing away from the guide pin 11. The two rollers 134 enable the guide member 122 to move along the axial direction or radial direction of the rollers 134, that is, the guide member 122 can move along the X direction or the Y direction.
[0081] In this embodiment, the guide member 122 has two sliding grooves C1 on its side facing away from the guide sleeve pin 11. Parts of the two rollers 134 are located in the two sliding grooves C1 respectively. The sliding grooves C1 and the pressure plate 133 cooperate to limit the movement distance of the guide member 122. Specifically, the width H1 of the sliding grooves C1 is greater than the diameter D of the rollers. The guide member 122 can move along the axial direction of the rollers 134 and also along the radial direction of the rollers 134.
[0082] It is worth noting that, in this embodiment, a preferred implementation is one in which the roller 134 can be moved 2 mm in the axial or radial direction.
[0083] Furthermore, the top surface of the housing 131 facing the guide pin 11 is an open end K, and the bottom surface of the housing 131 facing away from the guide pin 11 is provided with a second through hole K2. The second through hole K2 is connected to the open end K through the accommodating space S, and the tail 113 extends out of the housing 131 from the second through hole K2. The housing back 131 has a receiving groove C2 on the bottom surface of the guide pin 11. The receiving groove C2 surrounds the second through hole K2. The guide pin 11 also has a transition portion 114. The two ends of the transition portion 114 are respectively connected to the middle portion 112 and the tail portion 113. The floating component 13 also includes: a sliding plate 135, a gasket 136 and a fastener 137. The sliding plate 135 is disposed in the receiving groove C2 and surrounds the tail portion 113. The gasket 136 is sleeved on the tail portion 113. The gasket 136 is attached to one side of the sliding plate 135 and is engaged with the first step portion T1 of the transition portion 114. The fastener 137 is sleeved on the tail portion 113. The fastener 137 is attached to one side of the gasket 136 and is engaged with the second step portion T2 of the transition portion 114.
[0084] In this embodiment, the width H2 of the second step T2 is greater than the width H3 of the fastener 137.
[0085] Furthermore, the inner side of the housing 131 is provided with a limiting part 1311 surrounding the elastic member 132, and the pressure plate 133 is located above the limiting part 1311.
[0086] In this embodiment, the middle part 112 has a third step part T3 at one end near the head part 111, and the guide member 122 is sleeved on the third step part T3.
[0087] In this embodiment, a notch C3 is also provided on one side of the housing 131.
[0088] It is worth noting that, in this embodiment, using the female connector F as a UQDB04 female connector is a preferred implementation.
[0089] According to the connection structure of the above embodiment, the axial track and rolling movement reduce mutual friction. When the male head is pushed forward, it matches the female head more smoothly, avoiding leakage or failure caused by damage to the female head due to impact.
[0090] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the appended claims.
