[0003] The battery swap connector for new energy pure electric vehicles also has the functions of automatic insertion guidance and deviation correction, and the realization of the functions mainly depends on the connector floating structure. The connector floating structure on the market is generally designed by using compression springs, extension springs, gaskets, pins, floating housings, mounting housings, fixed housings and the like, and has the problems of a large number of parts, complex assembly and poor floating return effect. SUMMARY

[0004] The application is proposed to solve the above problems, and a connector floating structure is provided. The floating structure can realize floating in the XY direction within a certain range by adjusting the gap between the floating housing and the pin. The connector Z-direction reaction force and the XY-direction floating return force can be adjusted by setting the compression spring, the extension spring force value and the number of floating units, so as to meet the floating function requirements of different sizes of connectors.

[0005] The application is realized by the following technical scheme:

[0006] A connector floating structure comprises a plurality of vertically arranged floating units, and the plurality of floating units are uniformly and symmetrically arranged at the bottom of each corner of a floating housing edge panel. A fixed plate is arranged above the floating housing edge panel.

[0007] The fixed plate is provided with a mounting port corresponding to the main body of the floating housing. The floating housing is arranged in the mounting port of the fixed plate in the insertion direction and can float in all directions in the mounting port.

[0008] The floating unit comprises a pin, a floating block I, a floating block II and a compression spring arranged in sequence from top to bottom. The pin extends to the inside of the floating block I, the floating block II and the compression spring in sequence through the fixed plate and the floating housing edge panel, and a fixed block below the compression spring is sleeved at the bottom of the pin. The fixed block and the end face of the pin are matched to realize axial one-side limiting locking.

[0009] Further, the inner side wall of the floating block II is obliquely arranged horizontally with an extension spring for floating housing return.

[0010] Further, one end of the tension spring is fixed and limited in position by cooperating with the fixed shaft near the bottom of the inner end of the floating block I, and the other end is connected with the connecting shaft on the floating shell body to realize fixed and limited in position.

[0011] Further, the floating block I is matched with the pin shaft hole gap to realize free displacement in two axial directions.

[0012] Further, the floating block II is matched with the pin shaft through the stepped shaft hole to realize one-side axial limiting, and can be freely displaced in the reverse axial insertion direction.

[0013] Further, the edge panel of the floating shell is sleeved on the pin shaft, and the XY direction displacement is realized through the design of the shaft hole gap size.

[0014] Further, the upper surface of the edge panel of the floating shell is attached to the fixed plate and realizes one-way limiting, and the lower surface is attached to the floating block I and can realize free axial displacement.

[0015] Further, the fixed block is connected with the pin shaft through thread.

[0016] Further, the compression spring is sleeved on the pin shaft, one end is matched with the end surface of the floating block II, and the other end is matched with the plane of the fixed block, thereby realizing axial two-side limiting and providing spring force in the compressed state.

[0017] Further, the number of the floating units is four.

[0018] The beneficial effects of the present application are as follows:

[0019] 1. When the floating structure is in the initial state and the connector is not inserted, the floating shell reaches force balance in the XY plane (normal direction of the insertion direction) under the action of the four obliquely arranged tension springs, and is located at the original position, the tension spring provides the XY direction floating shell returning force, and the floating shell returning reliability is ensured.

[0020] 2. When the floating structure is working, the four fixed blocks are rigidly connected and fixed with the equipment end, the external force acts on the floating shell in the insertion direction, the floating shell is displaced in the axial direction of the pin shaft, the floating shell is displaced in the insertion direction and presses the floating block I, the floating block II and the compression spring, the compression spring is further compressed and the reaction force is increased after being pressed, and the spring force provides the connector Z upward (reverse direction of the insertion direction) reaction force.

[0021] When the external force is removed, the reaction force of the compression spring restores the floating shell, the floating block I and the floating block II to the initial position, and the four tension springs always provide reliable XY direction returning force to keep the original position during the process.

[0022] 3. The floating structure of this invention can achieve floating in the XY direction within a certain range by adjusting the gap between the floating shell and the pin shaft; by setting the compression spring, tension spring force, and number of floating units, the Z-axis reaction force and XY-axis floating return force of the connector can be adjusted to meet the floating function requirements of connectors of different sizes.

[0032] Example 1

[0033] As shown in the figure, a connector floating structure includes several vertically arranged floating units 10. The floating units 10 are evenly and symmetrically arranged at the bottom of each corner of the edge panel of the floating housing 1. The number of floating units is preferably four.

[0034] A fixing plate 2 is provided above the edge panel of the floating shell 1. The fixing plate 2 is provided with a mounting port 11 that matches the main body of the floating shell 1. The floating shell 1 is disposed in the mounting port 11 of the fixing plate 2 along the insertion direction, and the floating shell 1 can float in all directions and back and forth within the mounting port 11.

[0035] The floating unit 10 includes a pin 6, a floating block I 3, a floating block II 4, and a compression spring 5 arranged sequentially from top to bottom;

[0036] The pin 6 passes through the fixed plate 2 and the edge panel of the floating shell in sequence and extends into the floating block I 3, the floating block II 4, and the compression spring 5. A fixed block 7 is sleeved at the bottom of the pin 6 and located below the compression spring 5. The fixed block 7 is threadedly connected to the pin 6 and cooperates with the end face of the pin 6 to achieve axial unilateral limiting and locking.

[0037] When the floating structure is working, the four fixed blocks 7 are rigidly connected and fixed to the equipment end. The external force acts on the floating shell 1 along the insertion direction. The floating shell 1 is axially displaced along the pin 6. The floating shell 1 is displaced along the insertion direction and presses down on the floating block I 3, the floating block II 4, and the compression spring 5. After being subjected to the downward pressure, the compression spring 5 is further compressed and the reaction force is increased. The spring force provides the connector with an upward reaction force in the Z direction (opposite to the insertion direction).

[0038] When the external force is removed, the reaction force of the compression spring 5 will restore the floating shell, floating block I, and floating block II to their initial positions.

[0039] The edge panel of the floating shell 1 is fitted onto the pin 6. By adjusting the gap between the floating shell 1 and the pin 6, floating in the XY direction within a certain range can be achieved. The upper part of the edge panel of the floating shell 1 is attached to the fixed plate 2 to achieve unidirectional limiting, and the lower part is attached to the floating block I3 to achieve axial free displacement.

[0040] The floating block I3 is clearance-fitted with the shaft hole of the pin 6 to achieve free displacement in two axial directions. The floating block II4 is axially limited on one side by fitting with the pin 6 through the stepped shaft hole, and can move freely in the opposite direction along the axial insertion direction.

[0041] The compression spring 5 is sleeved on the pin 6, with one end cooperating with the end face of the floating block II 4 and the other end cooperating with the plane of the fixed block 7, so as to achieve axial limit on both sides and provide spring force in a compressed state.

[0042] Furthermore, the inner wall of the floating block II4 is also provided with a tension spring 8 for the floating shell to return to its original position. The tension spring 8 located on the same side of the floating shell is arranged in a figure-eight shape. One end of the tension spring 8 cooperates with the fixed shaft at the bottom of the inner side of the floating block I3 to achieve fixed positioning, and the other end is connected to the connecting shaft 9 on the floating shell 1 body to achieve fixed positioning.

[0043] The tension spring 8 provides spring force in a stretched state. When the floating structure is not in operation in its initial state, that is, when the connector is not inserted, the floating shell reaches force balance in the XY plane (normal direction of insertion direction) under the action of the tension spring 8 set at 4 oblique locations, and is located at the origin position. The tension spring 8 provides the floating shell centering force in the XY direction to ensure the reliability of the floating shell 1 centering.

[0044] Workflow:

[0045] When the floating structure is working, the four fixed blocks 7 are rigidly connected and fixed to the equipment end. The external force acts on the floating shell 1 along the insertion direction. The floating shell is axially displaced along the pin 6. The floating shell 1 is displaced along the insertion direction and presses down on the floating block I 3, the floating block II 4, and the compression spring 5. After being subjected to the downward pressure, the compression spring 5 is further compressed and the reaction force is increased. The spring force provides the connector with an upward reaction force in the Z direction (opposite to the insertion direction).

[0046] When the external force is removed, the reaction force of the compression spring 5 restores the floating shell 1, floating block I 3, and floating block II 4 to their initial positions. During the process, the four tension springs 8 consistently provide a reliable return-to-origin force in the XY directions.

[0047] In summary, the floating structure can achieve floating in the XY direction within a certain range by adjusting the gap between the floating housing 1 and the pin 6; by setting the compression spring 5, the tension spring force, and the number of floating units, the Z-direction reaction force and XY-direction floating return force of the connector can be adjusted to meet the floating function requirements of connectors of different sizes.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
