The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 5 As shown, the present invention provides an electrical signal connector, including an upper connector structure 1 and a lower connector structure 3. The vehicle body includes an upper body structure and a lower body structure, which are detachably connected. The upper connector structure 1 is mounted on the upper body structure of the vehicle, and the lower connector structure 3 is mounted on the lower body structure of the vehicle. The upper connector structure 1 is connected to a wiring harness on the upper body structure, and the lower connector structure 3 is connected to a wiring harness on the lower body structure.

[0027] Specifically, such as Figures 1 to 3 As shown, the lower connector structure 3 includes a lower housing, a first pair of plugs 304 disposed on the lower housing, a telescopic rod assembly 301, and a drive mechanism for controlling the linear movement of the telescopic rod assembly 301. The lower housing is fixedly disposed on the lower vehicle body structure, the first pair of plugs 304 are mounted on the lower housing, and the first pair of plugs 304 are electrically connected to the wiring harness on the lower vehicle body structure. The telescopic rod assembly 301 is movably disposed on the lower housing along the Z-axis (i.e., the Z-axis of the vehicle coordinate system), and the drive mechanism is disposed on the lower housing and connected to the telescopic rod assembly 301.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the upper structure 1 of the connector includes an upper housing, a second pair of plug-in 104 disposed on the upper housing and connected to the first pair of plug-in 304 by plug-in connection, and a fixed rod assembly 101 disposed on the upper housing and connected to the telescopic rod assembly 301 by magnetic attraction. The upper housing is fixedly disposed on the upper body structure, the second pair of plug-in 104 is mounted on the upper housing, and the second pair of plug-in 104 is electrically connected to the wiring harness on the upper body structure.

[0029] like Figures 1 to 4 As shown, the lower connector structure 3 further includes a first control component 309 disposed on the lower housing for emitting a sine wave to the telescopic rod assembly 301, and the upper connector structure 1 further includes a second control component 103 disposed on the upper housing for emitting a sine wave to the fixed rod assembly 101. The first control component 309 is fixedly disposed inside the lower housing, and the second control component 103 is fixedly disposed inside the upper housing. Multiple telescopic rod assemblies 301 are provided, and the number of fixed rod assemblies 101 is the same as the number of telescopic rod assemblies 301, with each fixed rod assembly 101 connected to a telescopic rod assembly 301 by magnetic attraction.

[0030] like Figures 1 to 4 As shown, the telescopic rod assembly 301 includes a first guide rod and a coil and a magnetic core disposed on the first guide rod, which is connected to the drive mechanism. The fixed rod assembly 101 includes a second guide rod and a coil and a magnetic core disposed on the second guide rod, which is disposed on the upper housing. The first guide rod is movable, while the second guide rod is fixedly disposed on the upper housing. The length directions of the first and second guide rods are parallel to the Z-direction.

[0031] When the upper and lower body structures of the vehicle are assembled, the first control component 309, according to the assembly command, controls the telescopic rod assembly 301 to emit a detection wave. The fixed rod assembly 101 of the connector upper structure 1 is received by the detection wave and wakes up the second control component 103. The second control component 103 then controls the fixed rod assembly 101 to emit another set of detection waves. After the telescopic rod assembly 301 receives the detection waves emitted by the fixed rod assembly 101, the first control component 309 and the second control component 103 respectively convert the detection waves emitted by the telescopic rod assembly 301 and the fixed rod assembly 101 into reverse tangent excitation, forming a mutually attractive magnetic field. The telescopic rod assembly 301 and the fixed rod assembly 101 are attracted together. After the connector is automatically aligned, the first control component 309 sends a command to the drive mechanism, which then starts to operate. The drive mechanism drives the telescopic rod assembly 301 to move linearly along the Z direction. The telescopic rod assembly 301 drives the fixed rod assembly 101 to move, which means that the telescopic rod assembly 301 can drive the entire upper structure 1 of the connector to move closer to the lower housing. Under magnetic attraction, the upper structure 1 of the connector is pulled down, and finally the first pair of plugs 304 and the second pair of plugs 104 are inserted. After the insertion is completed, the first control component 309 controls the locking device 2 to operate, and the upper structure 1 and the lower structure 3 of the connector are fixed together by the locking device 2. After locking is completed, the excitation disappears.

[0032] like Figures 1 to 3 As shown, the drive mechanism includes a drive motor mounted on the lower housing, a reduction mechanism 302 connected to the drive motor, and a lead screw 308 connected to the reduction mechanism 302. The lead screw 308 is connected to the telescopic rod assembly 301. The lead screw 308 and the first guide rod of the telescopic rod assembly 301 form a helical transmission pair. The power input end of the reduction mechanism 302 is connected to the motor shaft of the drive motor, and the power output end of the reduction mechanism 302 is fixedly connected to the lead screw 308.

[0033] In this embodiment, the reduction mechanism 302 is a worm gear mechanism. The worm of the reduction mechanism 302 is fixedly connected to the motor shaft of the drive motor, and the worm wheel of the reduction mechanism 302 is fixedly connected to the lead screw 308. The number of drive mechanisms is the same as the number of telescopic rod assemblies 301. Each drive mechanism is connected to one telescopic rod assembly 301, and all telescopic rod assemblies 301 are distributed around the outer periphery of the first pair of plug-in 304.

[0034] like Figures 1 to 3As shown, the lower housing includes a first base plate 303, a first side plate 307 disposed on the first base plate 303, and a first fixing plate 306 disposed on the first side plate 307. A first pair of inserts 304 are disposed on the first fixing plate 306, extending upward toward the first fixing plate 306. A guide shaft bushing 305 is disposed on the first fixing plate 306, and the telescopic rod assembly 301 passes through the guide shaft bushing 305. The first side plate 307 is located between the first fixing plate 306 and the first base plate 303, and is fixedly connected to the first fixing plate 306 and the first base plate 303. The drive mechanism is disposed on the first base plate 303 and located inside the first side plate 307. The guide shaft bushing 305 is fixedly disposed on the first fixing plate 306, and a first guide rod passes through the guide shaft bushing 305. The guide shaft bushing 305 guides the telescopic rod assembly 301, guiding the telescopic rod assembly 301 to move linearly along the Z direction.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the upper housing includes a second base plate 102, a second side plate 106 disposed on the second base plate 102, and a second fixing plate 105 disposed on the second side plate 106. A second pair of inserts 104 are disposed on the second fixing plate 105, extending downward toward the second fixing plate 105. The second side plate 106 is located between the second fixing plate 105 and the second base plate 102, and is fixedly connected to the second fixing plate 105 and the second base plate 102. A second control assembly 103 is disposed on the second base plate 102 and located inside the second side plate 106.

[0036] During the assembly of the upper and lower body structures, the mating telescopic rod assembly 301 and fixed rod assembly 101 are arranged vertically, with the fixed rod assembly 101 positioned above the telescopic rod assembly 301. The telescopic rod assembly 301 receives a sine wave from the first control component 309, which activates the second control component 103. The second control component 103 then controls the fixed rod assembly 101 to emit a sine wave. The telescopic rod assembly 301 detects the sine wave emitted by the fixed rod assembly 101. At this point, the first control component 309 and the second control component 103 respectively energize the telescopic rod assembly 301 and the fixed rod assembly 101, turning them into mutually attracting magnetic poles. The magnetic poles attract each other, generating a magnetic attraction force. Because it is a dual magnetic attraction force... Figure 5 The structure shown consists of two telescopic rod assemblies 301 and two fixed rod assemblies 101, and the upper part is a flexible connection. Therefore, manufacturing and installation errors of ±15mm can be eliminated, and fast and accurate alignment can be achieved. The alignment and positioning error of this device is ±0.02mm.

[0037] The excitation of this device adopts an arctangent curve. Initially, a weak excitation is generated, producing a slight attractive force. This attractive force generates axial tension. After ensuring accurate alignment, the excitation is gradually increased. Since the upper part is a flexible connection, during the connector connection process, the magnetic force generated between the telescopic rod assembly 301 and the fixed rod assembly 101 will gradually increase until the telescopic rod assembly 301 and the fixed rod assembly 101 come into contact, avoiding a strong collision of magnetic fields at one moment. Then, the first control component 309 controls the drive mechanism to operate, thereby driving the telescopic rod assembly 301 to descend. At this time, the excitation is kept at maximum. The telescopic rod assembly 301 drives the fixed rod assembly 101 to descend synchronously through magnetic attraction, automatically connecting the upper structure 1 of the connector and the lower structure 3 of the connector. Once the connection is completed, the locking device 2 locks the upper structure 1 of the connector and the lower structure 3 of the connector, at which point the excitation will disappear.

[0038] This excitation method ensures both functional requirements are met and energy efficiency is maintained after the function is finished. Furthermore, the use of an antitangential excitation mode avoids strong collisions between magnetic fields, achieving flexible contact.

[0039] When used for testing, a coil and a magnetic core are fixedly installed on the first guide rod, and a coil and a magnetic core are also fixedly installed on the second guide rod. When the device is activated, the first control component 309 controls the coil of the telescopic rod assembly 301 to emit a sine wave of a specific fixed frequency, and the second control component 103 controls the coil of the fixed rod assembly 101 to emit a sine wave of a specific fixed frequency, thereby realizing the testing function.

[0040] When used for magnetic attraction, the first control component 309 and the second control component 103 respectively control the coils of the telescopic rod assembly 301 and the fixed rod assembly 101 to be energized according to the arctangent curve to achieve the magnetic attraction function.

[0041] When the upper and lower body structures of the vehicle are separated, the connector needs to be disengaged. Locking device 2 is unlocked first, and locking device 2 is separated from the upper structure 1 of the connector. Then, the first control component 309 energizes the coil of the telescopic rod assembly 301 and controls the drive mechanism to operate. The drive mechanism drives the telescopic rod assembly 301 to rise, and the telescopic rod assembly 301 pushes the fixed rod assembly 101 to move upward. The fixed rod assembly 101 drives the upper structure 1 of the connector to move upward as a whole until the connector is disconnected. At this time, the telescopic rod assembly 301 is energized in the opposite direction, opposite to the magnetic field of the fixed rod assembly 101. A repulsive force is generated between the telescopic rod assembly 301 and the fixed rod assembly 101, thereby completely disconnecting the connector device and separating the first pair of plugs 304 from the second pair of plugs 104.
