[0002] With the gradual popularization of new energy electric vehicles, the commonly used on-board USB interfaces in electric vehicles are becoming more and more popular. Compared with fuel vehicles, there are more USB interfaces in electric vehicles, and often a large number of on-board USB interfaces are installed in the back row;

[0003] USB4.0 is the latest generation standard of USB interface. The maximum transmission speed of USB4.0 is up to 40Gbps, and the theoretical speed can reach 5000MB / s. It adopts USBType-C interface and supports bidirectional insertion, which solves the problem of the directionality of the previous USB interface. It has 24 built-in contacts, which is more complicated to detect. Compared with the earlier low version of USB interface, it can achieve the effect of bidirectional plugging. For the detection of bidirectional plugging, the pins in USB4.0 are often relatively set compared with the transmission pins, which can achieve the effect of bidirectional plugging and powering.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example, see Figures 1 to 7 A detection device for a vehicle-mounted USB interface includes a detection test platform 1, on which a conveying module and a plurality of detection modules are arranged, the detection module includes a plurality of detection end seats 2 connected to each other, and the detection end seats 2 are connected to an insertion detection end plate 3 through a linkage reciprocating component;

[0034] Furthermore, the linkage reciprocating assembly includes a control motor 18 arranged on the outermost detection end seat 2, a linkage chamber is opened inside the detection end seat 2, the output end of the control motor 18 is fixedly connected to a worm shaft 19 that passes through multiple linkage chambers, a vertical linkage shaft 20 is arranged in the linkage chamber, and a worm wheel 21 meshingly connected to the worm shaft 19 is arranged on the outer side wall of the vertical linkage shaft 20.

[0035] Both ends of the vertical linkage shaft 20 are fixedly provided with eccentric linkage disks 22 , the eccentric linkage disks 22 are rotatably connected with eccentric linkage rods 23 , and the other end of the eccentric linkage rods 23 is rotatably connected to the cutting detection end plate 3 .

[0036] It should be noted that the vertical linkage shaft 20 located on both sides of the worm gear 21 is connected to the detection end seat 2 through bearings, thereby achieving a supporting effect on the vertical linkage shaft 20 in the middle and ensuring the synchronous rotation of the eccentric linkage disks 22 on both sides.

[0037] A further benefit of adopting the above method is that when the worm shaft 19 is driven to rotate by controlling the motor 18, the worm wheel 21 connected to the worm shaft 19 is rotated, so that the vertical linkage shaft 20 drives the eccentric linkage disk 22 to rotate. During the rotation of the eccentric linkage disk 22, the insertion detection end plate 3 connected to it through the eccentric linkage rod 23 will be reciprocated, thereby allowing the signal detection plug-in 4 set at the end of the insertion detection end plate 3 to perform a reciprocating plug-in and unplug simulation test in the vehicle-mounted USB interface.

[0038] The cutting detection end plate 3 is connected to the detection end seat 2 through a sliding connection. Furthermore, the sliding connection includes a rectangular sliding opening opened on the detection end seat 2, and limited stable openings are arranged on both sides of the rectangular sliding opening. The cutting detection end plate 3 is located in the rectangular sliding opening and is connected to the limited stable opening through a sliding limit block 24.

[0039] By providing a sliding connection piece, it is possible to ensure that the insertion detection end plate 3 can move stably in the rectangular sliding opening, thereby ensuring the insertion quality of the signal detection plug-in 4 provided at its end.

[0040] The end of the insertion detection end plate 3 is connected to a signal detection plug-in 4, a detection control cavity is provided inside the signal detection plug-in 4, and both sides of the signal detection plug-in 4 are provided with an adapter detection port 5 adapted to the vehicle-mounted USB pin;

[0041] The inner wall of the adapter detection port 5 located on both sides of the signal detection plug-in 4 is provided with two metal detection guides 6 arranged oppositely, and the metal detection guides 6 are provided with contact signal guide balls 7, and the insertion detection end plate 3 is provided with a pneumatic independent control part for controlling the movement of the metal detection guides 6;

[0042] It should be noted that, under the squeezing action of the inclined sliding control block 25, the two metal detection guides 6 set opposite to each other will cause the originally inclined metal detection guides 6 to be squeezed and moved toward the adapter detection port 5, thereby contacting the pins on the vehicle-mounted USB interface, so that a single pin on the vehicle-mounted USB interface can be detected separately through the pneumatic independent control component, so that the signal detection of a single pin can be achieved to avoid the situation of one-side qualified and one-side fault.

[0043] Furthermore, the pneumatic independent control component includes an inclined sliding control block 25 arranged between the two metal detection guide plates 6, and a mounting frame 26 is fixedly connected to the insertion detection end plate 3, and an independent pneumatic push rod 27 is arranged on the mounting frame 26. The output end of the independent pneumatic push rod 27 is connected to the inclined sliding control block 25 through an "L"-shaped control rod 28.

[0044] It should be noted that each independent pneumatic push rod 27 is controlled to move by a solenoid valve, and the solenoid valve can be programmed to achieve precise control of the extension and retraction of each independent pneumatic push rod 27, thereby achieving the effect of controlling the detection of the vehicle-mounted USB pins one by one.

[0045] The signal detection plug-in 4 is provided with a wear-resistant strength penetration port 8 adapted to the vehicle-mounted USB pin, and the inner wall of the detection control cavity is slidably connected with two oppositely arranged telescopic push plates 9, and the telescopic push plates 9 are evenly provided with wear-resistant metal test pieces 10, and the two telescopic push plates 9 are connected by a connecting spring, and a built-in pneumatic push rod 11 is provided inside the insertion detection end plate 3, and the built-in pneumatic push rod 11 is connected to the telescopic push plate 9 through a joint control push piece;

[0046] When the wear resistance strength test of the vehicle-mounted USB pin is required, the wear resistance test can be performed on the vehicle-mounted USB pin through the wear-resistant metal test piece 10, and the connectivity of the vehicle-mounted USB pin can be tested through the metal detection guide 6 after the wear resistance test.

[0047] Furthermore, the joint control pusher includes a trapezoidal push seat 29 , and a plurality of inclined push blocks 30 that slide against the trapezoidal push seat 29 are evenly arranged on the telescopic push plate 9 , and the built-in pneumatic push rod 11 is connected to the trapezoidal push seat 29 through a push rod 31 .

[0048] It should be noted that when it is necessary to perform a wear resistance test on the vehicle-mounted USB pin, the built-in pneumatic push rod 11 is used to control the trapezoidal push seat 29 to move forward, driving the oblique push blocks 30 on both sides that are in conflict with it to drive the telescopic push plate 9 to move, thereby moving the wear-resistant metal test piece 10 originally housed in the wear resistance penetration port 8 outward for a wear resistance test.

[0049] A through opening is provided at the end of the detection control cavity, which passes through the side wall of the signal detection plug-in 4. A distance baffle 12 is arranged in the through opening. Distance pneumatic push rods 13 are respectively arranged on both sides of the insertion detection end plate 3. The distance pneumatic push rods 13 are connected to the distance baffle 12 through side pneumatic push rods 14. The moving distance of the distance pneumatic push rods 13 needs to be reversely compensated by the control motor 18.

[0050] Furthermore, the cutting detection end plate 3 is provided with a plurality of movable openings for the "L"-shaped control rod 28, the push rod 31 and the side pneumatic push rod 14 to move. The setting of the movable openings is the prior art and will not be described in detail here.

[0051] Under the action of the fixed-distance pneumatic push rod 13, the fixed-distance baffle 12 can be pushed outward, and the position of the metal detection guide 6 can be controlled by blocking the fixed-distance baffle 12, so that when detecting the installation distance of the pins in the vehicle-mounted USB interface (the pins and the shell are assembled, and the length of the pins is sufficient to fill the pin slots of the entire shell, but some defective pins are too short to fill the pin slots. The setting of the contact signal guide ball 7 can meet the detection of the pin slots close to the interface, thereby realizing the detection of the qualified rate of the pin and shell assembly), the fixed-distance detection effect can be achieved.

[0052] The conveying module includes a detection placement mold base 16 connected to the detection test platform 1 through an electric push rod 15, and the detection placement mold base 16 is evenly provided with placement openings 17 for placing the vehicle-mounted USB interface, wherein the size of the placement opening 17 is consistent with the size of the vehicle-mounted USB interface.

[0053] Furthermore, a rectangular movable opening is provided on the testing platform 1 , in which a rectangular slider 32 connected to the testing placement mold base 16 is provided, and the output end of the electric push rod 15 passes through the rectangular movable opening and is fixedly connected to the rectangular slider 32 .

[0054] When the vehicle-mounted USB interface is detected, the vehicle-mounted USB interface module is placed in the placement port 17, the vehicle-mounted USB interface is driven to move to the detection module by the electric push rod 15, and the distance between the signal detection plug-in 4 and the vehicle-mounted USB interface is controlled by the fixed distance baffle 12. After the signal detection plug-in 4 is inserted into the vehicle-mounted USB interface, according to the needs of signal detection, the metal detection guides 6 arranged on both sides of the signal detection plug-in 4 are controlled by the forward and backward movement of the independent pneumatic push rod 27 to respectively detect the pins of the vehicle-mounted USB interface on both sides. During the detection process, the effect of pin length detection and pin signal detection can be achieved by changing the position of the fixed distance baffle 12, thereby ensuring the accuracy of the USB interface detection process of version 4.0;

[0055] When the signal detection is completed, the eccentric linkage disk 22 can be driven to rotate by controlling the motor 18, thereby driving the insertion detection end plate 3 connected to the eccentric linkage rod 23 to be plugged in and out, and the opened wear-resistant metal test piece 10 can be quickly plugged in with the pins of the tested vehicle-mounted USB interface, thereby simulating the actual plug-in process, judging the quality of signal reception after frequent plugging and unplugging of the pins, and realizing effective detection of the vehicle-mounted USB interface.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
