Description

Technical Field

[0001] The present invention relates to the technical field of transmission line connection, and in particular to a high-frequency transmission line connection device for an unmanned vehicle. Background Art

[0002] Self-driving cars, also known as autonomous vehicles or driverless cars, are intelligent vehicles that use advanced technology to enable autonomous driving without the need for direct human driver control.

[0003] In the development of the autonomous vehicle industry, with the widespread application of sensors such as cameras and lidars and on-board computers, the use of transmission lines has greatly increased to meet the high-speed transmission needs of large amounts of images, point cloud data, etc., and the performance requirements of transmission lines are getting higher and higher. In the existing technology, the inner holes and outer needles located on the two transmission lines are prone to displacement when docking, and the outer needles are easily damaged during operation, thereby affecting the transmission performance of the transmission line. In addition, when inspecting and repairing the transmission line, it is usually necessary to disconnect. When multiple transmission lines are disconnected at the same time, confusion is easily caused, which makes it inconvenient for the operator to distinguish the corresponding transmission lines. To this end, we propose a high-frequency transmission line connection device for autonomous vehicles to solve the above-mentioned defects. Summary of the Invention

[0006] The outer surface of the male connector abuts against the oblique wedge, the sheath is movably connected to the male connector, and the male connector is movably connected to the female connector, and the oblique wedge is used to prevent the male connector from being separated from between the sheath and the female connector;

[0007] An inner hole is provided at the axis center of the female connector, and an outer ring body is fixedly mounted on the surface of the female connector;

[0008] The surface of the female connector is symmetrically provided with oblique cuts, and a guide groove is penetrated through the oblique cuts. A slider is slidably connected in the guide groove, and a semi-ring body is fixedly connected to the surface of the slider.

[0009] Preferably, a mounting block is fixedly connected to the outer surface of the inner hole, and a cable for connecting the transmission line 1 and the inner hole is arranged in the mounting block.

[0010] Preferably, guide plates are slidably connected above and below the mounting block, the guide plates are slidably connected to the slider, and a spring three is sleeved and installed between the guide plates and the mounting block.

[0011] Preferably, a slip ring is slidably connected to the female connector, push rods are symmetrically installed on the top and bottom of the slip ring, and a second spring is sleeved and installed at the connection between the slip ring and the female connector.

[0012] Preferably, a U-shaped rod is further provided on the female joint, a pressure plate is hinged at the bottom of the U-shaped rod, the pressure plate is rotatably connected to the female joint, and a torsion spring is installed at the connection between the pressure plate and the U-shaped rod.

[0013] Preferably, a baffle is fixedly installed on one side of the pressure plate close to the U-shaped rod, and the push rod abuts against the U-shaped rod. The function of the baffle is to limit the flipping angle of the pressure plate so that the push rod will not cause the pressure plate to flip during the return process.

[0015] Preferably, the end of the male connector close to the transmission line is rotatably connected to an unlocking ring, the inner surface of the unlocking ring is fixedly connected to an arc strip, and the inner surface of the arc strip abuts against one end of the buckle strip.

[0016] Preferably, the male connector is provided with an outwardly protruding bevel ring on one side opposite to the sheath, which serves to facilitate mutual clamping and locking.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, by providing the inclined wedge and sheath, when connecting the transmission lines, the male connector is first passed through the inclined wedge. At this time, the male connector is sheathed in the sheath, but there is no conduction between the two transmission lines. When connecting, it is convenient and quick to pre-dock. When a short disconnection is required, the two transmission lines can be partially disconnected, making it easy to identify and straighten the transmission lines.

[0019] 2. In the present invention, during docking, the male connector pushes the slip ring on the female connector, causing the pressure plate to press the guide plate downward, causing the slider to extend outward within the guide plate, docking the two half-rings, forming a slightly inclined circular ring at the opening to protect the outer needle. If the outer needle is tilted, the outer needle can be corrected to align with the inner hole and complete the connection;

[0020] 3. In the present invention, when the buckle strip contacts the end face of the sheath, it automatically buckles and locks the sheath, locking the male connector and the female connector. To unlock, simply rotate the unlocking ring to complete the unlocking.

[0021] 4. In the present invention, during the unlocking process, the arc-shaped strip presses the buckle strip. After one end of the buckle strip is tilted, the spring 2 is quickly released, which can quickly disconnect the inner hole and the outer needle. The female connector is quickly popped open, and there is no need to manually peel off the two transmission lines, which is convenient for operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figures 1 to 3 A technical solution of an embodiment of the present invention includes a transmission line 1 and a transmission line 2, wherein one end of the transmission line 1 is electrically connected to a male connector 3, and one end of the transmission line 2 is electrically connected to a female connector 4, and the outer sheath of the female connector 4 is provided with a sheath 5;

[0033] The top and bottom of the sheath 5 are slidably connected to the mounting rod 6, and a spring 7 is sleeved and installed at the connection between the mounting rod 6 and the sheath 5. The ends of the mounting rods 6 that are close to each other are fixedly connected to an inclined wedge 8, which passes through the sheath 5. The ends of the mounting rods 6 that are away from each other are fixedly connected to a dial head 9;

[0034] The outer surface of the male connector 3 abuts against the oblique wedge 8, the sheath 5 is movably connected to the male connector 3, and the male connector 3 is movably connected to the female connector 4. The oblique wedge 8 is used to prevent the male connector 3 from detaching from between the sheath 5 and the female connector 4;

[0035] An inner hole 10 is provided at the axis center of the female connector 4, and an outer ring body 11 is fixedly mounted on the surface of the female connector 4;

[0036] The male connector 3 and the sheath 5 are both provided with an outwardly protruding bevel ring on the side opposite to each other, which is used to facilitate mutual engagement and locking;

[0037] In this embodiment, during installation, when the male connector 3 has just passed the inclined wedge 8, the male connector 3 can still continue to move forward, but the male connector 3 cannot return without pushing the dial head 9 outward.

[0038] See also Figures 4 to 6 , a technical solution of an embodiment of the present invention: the surface of the female connector 4 is symmetrically provided with an oblique cut 12, a guide groove 13 is formed through the oblique cut 12, a slider 15 is slidably connected in the guide groove 13, and a semi-ring body 16 is fixedly connected to the surface of the slider 15;

[0039] The outer surface of the inner hole 10 is fixedly connected with a mounting block 14, and a cable for conducting transmission line 1 and the inner hole 10 is arranged in the mounting block 14;

[0040] The guide plates 17 are slidably connected above and below the mounting block 14. The guide plates 17 are slidably connected to the slider 15. A spring 25 is sleeved and installed between the guide plates 17 and the mounting block 14.

[0041] A slip ring 18 is slidably connected to the female connector 4, and push rods 19 are symmetrically installed on the top and bottom of the slip ring 18. A spring 20 is sleeved and installed at the connection between the slip ring 18 and the female connector 4;

[0042] The female connector 4 is also provided with a U-shaped rod 21, the bottom of the U-shaped rod 21 is hinged with a pressure plate 22, the pressure plate 22 is rotatably connected to the female connector 4, and a torsion spring 23 is installed at the connection between the pressure plate 22 and the U-shaped rod 21;

[0043] A baffle 24 is fixedly mounted on one side of the pressure plate 22 near the U-shaped rod 21. The push rod 19 abuts against the U-shaped rod 21. The baffle 24 limits the turning angle of the pressure plate 22 so that the push rod 19 does not cause the pressure plate 22 to turn over during the return process.

[0044] An outer needle 26 is fixedly connected to the axis of the male connector 3;

[0045] In this embodiment, when unlocking, the slip ring 18 drives the push rod 19 to return to its original position, which in turn drives the U-shaped rod 21 to rotate in the opposite direction and triggers the torsion spring 23 to twist. During this process, the pressure plate 22 will not swing in the opposite direction. After the push passes the U-shaped rod 21, the torsion spring 23 drives the U-shaped rod 21 to automatically return to its original position.

[0046] In this embodiment, the two half ring bodies 16 are joined together to form a circular ring with an inclined arc on the inner surface, which facilitates smooth contact with the end of the outer needle 26 and plays a guiding role;

[0047] See also Figures 7 and 8 , a technical solution of an embodiment of the present invention: a buckle strip 27 is hingedly connected to the end of the male connector 3 close to the transmission line 1, one end of the buckle strip 27 is connected to a spring 28, and the end of the buckle strip 27 away from the spring 28 is movably engaged with the sheath 5;

[0048] The end of the male connector 3 close to the transmission line 1 is rotatably connected to an unlocking ring 29, and the inner surface of the unlocking ring 29 is fixedly connected to an arc strip 30, and the inner surface of the arc strip 30 abuts against one end of the buckle strip 27;

[0049] In this embodiment, in the initial state, the buckle strip 27 is in an inclined state. After being locked with the sheath 5, the buckle strip 27 is in a slightly horizontal state. During the unlocking process, the buckle strip 27 is inclined toward the other end, and the end in contact with the sheath 5 is tilted.

[0050] The use method and advantages of the present invention: The high-frequency transmission line connection device for unmanned vehicles has the following working process:

[0051] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown:

[0052] S1: During connection, the operator holds transmission line 1 and transmission line 2, respectively, and positions male connector 3 opposite female connector 4, inserting male connector 3 into the gap between sheath 5 and female connector 4. When the end of male connector 3 enters sheath 5, it contacts upper and lower inclined wedges 8. The inclined wedges 8 are pushed, compressing spring 1 7. After the end of male connector 3 passes through inclined wedges 8, spring 1 7 returns to its original position, confining male connector 3 within sheath 5. This facilitates quick and easy connection.

[0053] S2: As the male connector 3 continues to be pushed inward, the end face of the male connector 3 contacts the slip ring 18 and pushes the slip ring 18 forward. During this process, the spring 20 is gradually compressed. At this time, the outer needle 26 in the male connector 3 approaches the inner hole 10. When the push rod 19 contacts the U-shaped rod 21, the U-shaped rod 21 is pushed to rotate. Through the baffle 24, the pressure plate 22 is pushed downward to flip the guide plate 17 downward and compress the spring 3 25. During this process, the slider 15 sliding in the guide plate 17 extends outward along the guide groove 13 and moves along the guide groove 13. The guide groove 13 slides, driving the semi-ring body 16 to wrap the outer ring body 11. The two semi-ring bodies 16 form a circle. When the outer needle 26 approaches the inner hole 10, the angle of the outer needle 26 is corrected so that the outer needle 26 and the inner hole 10 are axially aligned, so that the outer needle 26 can be smoothly inserted into the inner hole 10. When the tip of the outer needle 26 enters the inner hole 10, the push rod 19 is disconnected from the U-shaped rod 21, and the guide plate 17 returns to its position, so that the semi-ring body 16 is retracted and enters the inner part of the bevel cut 12. The slip ring 18 continues to be pushed forward by the male connector 3.

[0054] S3: When the slip ring 18 slides to the end, the buckle strip 27 provided on the outer surface of the male connector 3 contacts the surface of the sheath 5, and follows the inclined surface of the sheath 5 so that the buckle strip 27 buckles the sheath 5. At this time, the buckle strip 27 changes from an inclined state to a horizontal state, and compresses the spring four 28 for a certain distance. The outer needle 26 is docked with the inner hole 10, the male connector 3 and the female connector 4 are docked and locked, and the transmission line 1 and the transmission line 2 are connected. When the transmission line needs to be disconnected, the operator rotates the unlocking ring 29 to make the arc-shaped strip 30 corresponding to the buckle strip 27 press down one end of the buckle strip 27, so that the end of the buckle strip 27 in contact with the sheath 5 is tilted, and then the spring two 20 is quickly released, so that the transmission line two 2 and the female connector 4 are quickly ejected, and the inner hole 10 and the outer needle 26 are quickly disconnected.
