Description

Technical Field

[0001] The invention relates to the technical field of blind plug-in joints, and in particular to a large-size omnidirectional floating blind plug-in mechanism. Background Art

[0002] Floating blind-mating technology is an advanced connection technology. Its main feature is that it can achieve accurate and safe connection between plugs and sockets without directly observing the mating surface or interface, thereby realizing the transmission of electrical signals, fluid signals and other signals. Floating blind-mating technology combines the characteristics of floating connection and blind-mating connection, so it is widely used in application scenarios such as liquid cooling systems and fluid connectors.

[0003] Traditional floating blind-mating technology is achieved by designing a floating mechanism at one end of the connector and a guiding mechanism at the other end; this floating blind-mating technology allows the connector to float within a small range during the connection process, thereby absorbing the assembly tolerance and position deviation between the devices, ensuring that the connector can be automatically aligned when connected, and reducing the difficulty and error of the connection. However, the existing floating blind-mating technology is suitable for plane floating, that is, the connector can only eliminate the error when the socket or plug is connected in parallel by floating. When the socket or plug is approached at a certain tilt angle, precise plugging cannot be achieved. In addition, the existing floating blind-mating technology is suitable for scenarios with small floating amounts and requires manual cooperation. However, with the rapid development of modern technology, the requirements for intelligence and automation are getting higher and higher, and the floating blind-mating technology within a small size range can no longer meet the use requirements.

[0004] Therefore, the present invention provides a blind plug-in mechanism with a large floating range, which is used to realize the automatic connection and separation function of the circuit when two vehicles are connected to each other. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a large-size omnidirectional floating blind plug-in mechanism, which solves the problem that the existing floating blind plug-in technology cannot achieve angle floating.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A large-size omnidirectional floating blind plug-in and pull-out mechanism, comprising a floating end and a moving end, wherein the floating end and the moving end are movably connected;

[0008] The floating end includes a first base, on which an angle floating mechanism and a plane floating mechanism are installed; a connector socket is arranged on the plane floating mechanism;

[0009] The moving end includes a mounting bracket, a transmission mechanism is mounted on the mounting bracket, and a connector plug is connected to the transmission mechanism;

[0010] The connector plug and the connector socket mate.

[0011] In this solution, the transmission mechanism on the moving end drives the connector plug to move toward the connector socket, thereby realizing the connection between the connector plug and the connector socket; during the connection process, the connector socket realizes angle floating through the angle floating mechanism and realizes horizontal floating through the plane floating mechanism, thereby compensating for the position deviation of the connector plug, thereby realizing precise connection between the connector plug and the connector socket.

[0012] Furthermore, the planar floating mechanism comprises an outer frame, the bottom of the outer frame is mounted on the base; the inner side of the outer frame is connected to a floating frame via a spring assembly, the inner side of the floating frame is mounted with a socket fixing block, and the inside of the socket fixing block is mounted with a connector socket;

[0013] An insert positioning block is arranged on the outside of the outer frame, and a trumpet-shaped positioning hole expanding outward is opened in the center of the insert positioning block; a fixing rod is installed on the side of the floating frame close to the angle floating mechanism, and the fixing rod is movably connected with the angle floating mechanism through a universal joint assembly.

[0014] In this solution, the floating frame is fixed by a spring assembly. When the connector plug is close, the connector socket can float upward, left, right and downward to a certain extent under the buffering action of the spring assembly. The specific floating amount in each direction can reach ±20mm, which ensures that the position deviation of the connector plug when docking can be compensated, ensuring the precise docking of the connector plug and the connector socket.

[0015] Furthermore, the angle floating mechanism includes a back plate, two left and right limit blocks are respectively installed on both sides of the back plate, and two upper and lower limit blocks are respectively installed on the top and bottom of the back plate; a longitudinal adjustment frame is arranged between the two left and right limit blocks and the two upper and lower limit blocks, and a transverse adjustment frame is arranged inside the longitudinal adjustment frame;

[0016] The two left and right limit blocks are provided with sliding grooves on opposite sides, and longitudinal sliders are slidably connected in the two sliding grooves; the two longitudinal sliders are connected to the two sides of the longitudinal adjustment frame on the sides close to the longitudinal adjustment frame; the inner side of the longitudinal adjustment frame is connected to the two sides of the transverse adjustment frame through two sets of transverse rectangular coil springs;

[0017] The two upper and lower limit blocks are connected to the top and bottom of the longitudinal adjustment frame through two sets of longitudinal rectangular coil springs respectively; the top and bottom of the inner side of the longitudinal adjustment frame are provided with slide grooves, and the slide grooves are slidably connected with transverse sliders; the two transverse sliders are connected to the top and bottom of the transverse adjustment frame respectively;

[0018] The lateral adjustment frame is movably connected with the fixing rod through a universal joint assembly.

[0019] In this solution, a universal joint assembly is designed between the transverse adjustment frame and the fixed rod. During the docking process between the connector plug and the connector socket, the fixed rod, the floating frame and the connector socket are integrally moved relative to the fixed end of the universal joint assembly, thereby realizing angular floating. During floating, the longitudinal adjustment frame together with the longitudinal slider slides along the slide grooves on the inner side of the left and right limit blocks, so that the fixed end of the universal joint assembly can adaptively follow the connector socket to move in the longitudinal direction; the transverse adjustment frame together with the transverse slider slides along the slide grooves on the inner side of the longitudinal adjustment frame, so that the fixed end of the universal joint assembly can adaptively follow the connector socket to move in the transverse direction; this design supports the connector socket through the universal joint assembly to prevent the connector socket from retreating during the plug-in process, and at the same time realizes the movable installation of the fixed end of the universal joint assembly, preventing the connector socket from being unable to float horizontally due to the length of the universal joint assembly when floating horizontally to overcome the horizontal direction error during the plug-in process, thereby avoiding motion interference during horizontal floating and angular floating.

[0020] Furthermore, the spring assembly includes two groups of transverse floating springs and two groups of longitudinal floating springs; one end of the transverse floating spring is connected to the middle of both sides of the floating frame, and the other end of the transverse floating spring is connected to the corner of the outer frame; one end of the longitudinal floating spring is connected to the middle of the top and bottom of the floating frame, and the other end of the longitudinal floating spring is connected to the corner of the outer frame.

[0021] Furthermore, the mounting and fixing frame includes a second base, a bottom plate is installed on the second base, two side plates are connected to the bottom plate, and a mounting frame is connected between the two side plates; a transmission mechanism is provided on the mounting frame, and a plug fixing plate is connected to the transmission mechanism; the connector plug is installed on the plug fixing plate; a positioning pin is provided on the plug fixing plate, and the end of the positioning pin is a contracted conical chamfer.

[0022] In this solution, the transmission mechanism drives the plug fixing plate to move, thereby driving the connector plug to approach the connector socket; during the approach process, the positioning pin is inserted into the positioning hole of the positioning block, thereby limiting the connector plug and the connector socket.

[0023] Furthermore, the transmission mechanism includes a motor, which is fixed on a mounting frame; a worm is connected to the output shaft of the motor, and the worm is connected to the worm wheel; a nut sleeve is fixedly connected to one side of the worm wheel, and the nut sleeve is fixed to the mounting frame through a mounting seat; a threaded screw is connected to the internal thread of the nut sleeve, and the threaded screw passes through a through hole in the center of the worm wheel; a moving block is connected to the end of the threaded screw, and the side of the moving block away from the threaded screw is installed on the plug fixing plate.

[0024] In this solution, when electric drive is used, the motor drives the worm to rotate, and the worm drives the turbine to rotate; the nut sleeve and the turbine rotate synchronously, and the nut sleeve rotates to drive the threaded screw to move through the thread action, and then drives the plug fixing plate to move through the moving block.

[0025] Furthermore, the end of the worm is connected to the manual transmission shaft via a spur gear set; the manual transmission shaft is connected to the manual input shaft via a helical gear set.

[0026] In this solution, when using manual drive, the operator manually rotates the input shaft, the manual input shaft drives the manual transmission shaft to rotate through the bevel gear set, the manual transmission shaft drives the worm to rotate through the spur gear set, and then drives the plug fixing plate forward or backward; this design connector plug has two driving modes: manual drive and electric drive, which has a wide range of applications and many applicable scenarios.

[0027] Furthermore, a plurality of through holes are provided around the mounting frame, and a guide rod is provided through each through hole, and the end of the guide rod is connected to the plug fixing plate;

[0028] A crossbeam is connected between two guide rods located on the same horizontal line, and a sensing block is installed on the crossbeam.

[0029] In this solution, the plug fixing plate can move more smoothly under the guidance of the guide rod.

[0030] Furthermore, a backward sensing sensor and a forward sensing sensor are also installed on the top of the mounting frame.

[0031] In this solution, a backward sensing sensor and a forward sensing sensor are used to collect the operation information of the connector plug, which is convenient for realizing the plugging and unplugging action through program-controlled transmission mechanism.

[0032] Furthermore, the conical chamfer angle of the end of the positioning pin is 45°.

[0033] The beneficial effects of the present invention are:

[0034] The large-size omnidirectional floating blind plug-in and pull-out mechanism provided by the present invention adopts a transmission mechanism to drive the connector plug to move toward the connector socket, thereby realizing the plug-in connection between the connector plug and the connector socket; during the plug-in connection process, the connector socket realizes angle floating through the angle floating mechanism, and realizes horizontal floating through the plane floating mechanism. The plane floating mechanism and the angle floating mechanism are used in combination, so that the connector socket has a plane floating amount of ±20mm and an angle of ±3°, thereby realizing the precise plug-in connection between the connector plug and the connector socket. The floating frame in the plane floating mechanism is fixed by a spring assembly. When the connector plug is close, the connector socket can float upward, left, right and downward to a certain extent under the buffering action of the spring assembly, and the position deviation of the connector plug when docking is compensated, thereby ensuring the precise docking of the connector plug and the connector socket.

[0035] The large-size omnidirectional floating blind plug-in mechanism provided by the present invention introduces the universal joint mechanism and the transmission mechanism into the floating blind plug-in connector for the first time, which improves the intelligence and automatic change of the mechanism. Through the cooperation of the universal joint and the spring assembly, the connector socket not only has the plane floating function, but also has the angle floating function. Compared with the existing floating blind plug-in technology, the plane floating amount is larger, and the angle floating can be realized. By adjusting the size of the angle floating mechanism and the plane floating mechanism and selecting the spring and universal joint of the corresponding specifications, the floating mechanism can have different floating amounts. The transmission mechanism is designed at the moving end to replace the manual plug-in operation; at the same time, it is also connected to the manual input shaft through the helical gear assembly and the spur gear assembly, and is compatible with the two driving modes of electric drive and human drive. Adjusting the power output of the transmission mechanism can provide different sizes of plug-in and pull-out forces for the connector plug, and can also adjust the movement stroke of the connector plug to meet the plug-in distance requirements under different environments. The moving end is designed with a positioning pin, and the connector plug has completed the preliminary positioning through the positioning pin before plugging, so that the plugging of the connector plug and the connector socket is more accurate and reliable.
