DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0020] According to the following Figure 1-Figure 11 The adapter plug assembly suitable for detecting different charging piles provided in an embodiment of the present invention is described.

[0021] Embodiment 1: See also Figure 1 and Figure 2 As shown, the adapter plug assembly suitable for detecting different charging piles according to the embodiment of the present invention includes a box body 21, a pin shaft 10 is fixedly provided on the upper side of one side of the box body 21, one side of the box cover 22 is rotatably mounted on the pin shaft 10, and the pin shaft 10 is fixed to the box body 21 through a shaft seat 101. Rotating the box cover 22 can put the box body 21 in an open or closed state. Preferably, a handle 1 is provided on one side of the box body 21 to facilitate carrying the device.

[0022] Preferably, a limiting frame 11 is further provided on one side of the box body 21 close to the pin shaft 10 to limit excessive opening of the box cover 22 .

[0023] like Figure 1 A detector 8 is arranged in the box body 21, and the detector 8 is used to detect the charging pile after the charging pile is connected.

[0024] Continue to refer to Figure 1 , an adapter 5 is also provided, and the adapter 5 has at least two ( Figure 1 Six adapters 5 are provided, and every three adapters 5 form a row), and each adapter 5 is applicable to a different type of charging pile, so that when the device detects the charging pile, it can be used for charging piles of various types.

[0025] like Figure 3-Figure 6 As shown, a positioning mechanism 6 is also provided, and the positioning mechanism 6 is used to accommodate each adapter 5. Each positioning mechanism 6 is used to accommodate one adapter 5. The positioning mechanism 6 includes a fixing cylinder 61, and the fixing cylinder 61 is fixed on the box cover 22, and has an accommodating space therein for accommodating the adapter 5.

[0026] In order to ensure that the adapter 5 can be in a clamped or non-clamped state (the non-clamped state also has a clamping force, but the pressure is smaller than the clamped state), the positioning mechanism 6 also includes a radial pressure cylinder 66, an arc pressure plate 63 and an axial pressure cylinder 62. The radial pressure cylinder 66 is located in the fixed cylinder 61. The inner surface of the radial pressure cylinder 66 is an inclined surface, that is, the space inside the cylinder is a conical structure. There are at least three groups of arc pressure plates 63. The outer surface of the arc pressure plates 63 is an inclined surface. The three groups of arc pressure plates 63 form a truncated cone structure (six arc pressure plates 63 are provided in the figure), and the arc pressure plates 63 are located on the inner wall of the radial pressure cylinder 66. The arc pressure plates 63 are limited to be able to move radially along the fixed cylinder 61. When the arc pressure plate 63 moves radially, it can press the adapter 5, so that the adapter 5 is in a position-locked state; and the axial pressure cylinder 62 is located on the side of the arc pressure plate 63 away from the box body 21, and is used to apply axial pressure to the radial pressure cylinder 66, so that the relative position of the inclined surface of the radial pressure cylinder 66 and the inclined surface of the arc pressure plate 63 changes. When the positions of the two inclined surfaces change relatively, the pressure of the radial pressure cylinder 66 on the arc pressure plate 63 will change, thereby adjusting the pressure of the arc pressure plate 63 on the adapter 5, which can be specifically adjusted to a pressing or non-pressing state. In the pressing state, the position of the adapter 5 is locked, and in the non-pressing state, the adapter 5 is convenient to be taken out of the positioning mechanism 6 for use.

[0027] In order to realize that the positioning mechanism 6 can lock the position of the adapter 5 when the box cover 22 is closed, and can not press the adapter 5 when the cover is opened (this is because the adapter 5 is not needed in the closed state and is generally in a transportation state, and locking the position of the adapter 5 can prevent it from falling off; and the adapter 5 is in a state of waiting for use in the open state, and is in a non-pressed state, so the adapter 5 can be easily taken out of the positioning mechanism 6 without wear), a toothed track wheel 12 and a transmission assembly are also provided here, combined with Figure 3 , Figure 7 - Fig. 9 As shown, the toothed track wheel 12 is fixed on the pin shaft 10, and a traveling gear 13 capable of meshing with the toothed track wheel 12 is provided in the box cover 22, so that the traveling gear 13 can rotate forward and reverse when the box cover 22 is opened and closed along the pin shaft 10. The transmission assembly is located in the box cover 22, and is used to transmit the rotational force of the traveling gear 13 to the axial pressure cylinder 62, thereby forming a state in which the axial pressure cylinder 62 squeezes the radial pressure cylinder 66.

[0028] Therefore, the adapter plug assembly suitable for different charging pile detections provided in the embodiment of the present invention can enable the positioning mechanism 6 to not compress the adapter 5 by opening the box cover 22, and conversely can enable the positioning mechanism 6 to clamp the adapter 5 by closing the cover, thereby avoiding collision damage caused by the adapter 5 falling off during transportation.

[0029] Preferably, in order to facilitate the installation of the toothed track wheel 12 and the traveling gear 13 , a receiving box 222 is further provided on the box cover 22 , and a notch 221 is provided below the receiving box 222 and below the box cover 22 .

[0030] Preferably, a female lock 42 is provided on the side of the box body 21 away from the pin shaft 10, and a male lock 41 is provided on the side of the box cover 22 away from the pin shaft 10. The male lock 41 is snapped with the female lock 42 to lock the box cover 22 to the box body 21, and due to the locking of the male lock 41 with the female lock 42, the transmission mechanism can further ensure the position locking of the axial pressure cylinder 62.

[0031] In order to ensure that the arc pressure plate 63 can only move radially when it is subjected to the pressure of the radial pressure cylinder 66, a guide block 631 is fixedly provided radially on the outer surface of the arc pressure plate 63, an avoidance groove 661 is provided in the area opposite to the guide block 631 on the radial pressure cylinder 66, and a limiting groove 611 is provided in the area opposite to the radial pressure cylinder 66 on the fixed cylinder 61. The guide block 631 can move radially in the limiting groove 611. When the radial pressure cylinder 66 is subjected to the axial pressure from the axial pressure cylinder 62, Figure 4 From the perspective shown, the radial pressure cylinder 66 can move to the left, and when moving to the left, it can generate an axial and a radial component force on the arc pressure plate 63. However, due to the limiting effect of the guide block 631, the arc pressure plate 63 can radially press the adapter 5.

[0032] Preferably, the axial length of the avoidance groove 661 is greater than the axial length of the guide block 631 , providing a moving space for the axial movement of the radial pressure cylinder 66 .

[0033] like Figure 4 and Figure 6 In order to ensure that the arc pressure plate 63 does not fall off the radial pressure cylinder 66 when the adapter 5 is not inserted, a limiting rod 663 is fixed in the avoidance groove 661, and a through hole 632 is provided on the guide block 1 631. The limiting rod 663 passes through the through hole 632, so that the arc pressure plate 63 can be limited on the radial pressure cylinder 66. Preferably, the diameter of the through hole 632 is larger than the diameter of the limiting rod 663.

[0034] like Figure 5 and Figure 6In order to conveniently prompt the operator to insert the maximum threshold of the adapter 5, a baffle 64 is provided at one end of the fixed cylinder 61 close to the axial pressure cylinder 62. The baffle 64 can prevent the adapter 5 from being continuously inserted, thereby prompting the operator that the adapter 5 has been inserted to the end. Preferably, a positioning rod 641 is installed between the baffle 64 and the fixed cylinder 61, and a clearance groove 621 for accommodating the positioning rod 641 is opened on the axial pressure cylinder 62, and the axial length of the clearance groove 621 is greater than the axial length of the positioning rod 641 along the axial direction of the fixed cylinder 61, thereby preventing the positioning rod 641 from blocking the axial movement of the axial pressure cylinder 62.

[0035] Preferably, the positioning rod 641 should be inserted into the inner wall of the fixing tube 61 , and a second limiting groove 612 adapted to the positioning rod 641 is provided on the inner wall of the fixing tube 61 .

[0036] Preferably, a guide portion 613 is provided at the insertion port of the fixed cylinder 61. The inner diameter of the guide portion 613 is relatively small, which can guide the inserted adapter 5 and prevent the adapter 5 from falling off from the positioning mechanism 6 when the arc pressure plate 63 has not yet pressed the adapter 5 during the closing process.

[0037] like Figure 1 Preferably, a receiving hole is opened in the box body 21, a transfer female end 3 is provided in the receiving hole, and a wire connected to the detector 8 is provided on the transfer female end 3. When the charging pile needs to be inspected, the transfer female end 3 is taken out from the receiving hole, and then the adapter 5 adapted to the charging pile is taken out, one end of the adapter 5 is connected to the transfer female end 3, and the other end is inserted into the charging pile for inspection.

[0038] Combination Figure 3 , Figure 7 and Figure 8 As shown, specifically, in order to achieve the transmission effect of the above-mentioned transmission assembly, a rod body 65 (the rod body 65 has threads) is installed in the middle of the axial pressure cylinder 62 through threads, and the rotation of the rod body 65 can cause the axial pressure cylinder 62 to produce axial movement; and the transmission assembly includes a gear transmission assembly 7, and the gear transmission assembly 7 includes a driven gear 71, an idler gear 72, a main gear 73, a coaxial gear 77 and a worm 76.

[0039] Among them, the driven gear 71 is fixed at one end of the rod body 65, the idler gear 72 is meshed between two adjacent driven gears 71, the main gear 73 is meshed below the lowest driven gear 71, one side of the traveling gear 13 is meshed with the toothed track wheel 12, and the other side of the traveling gear 13 is meshed with the coaxial gear 77, one end of the worm 76 is fixed at the center of the coaxial gear 77, a worm wheel 75 is meshed above the worm 76, and a transmission shaft 74 is fixed between the worm wheel 75 and the main gear 73.

[0040] In this embodiment, when the box cover 22 is closed, the running gear 13 runs and rotates on the toothed track wheel 12, thereby driving the coaxial gear 77 to rotate. When the coaxial gear 77 rotates, the worm 76 thereon can also rotate, thereby driving the worm wheel 75 to rotate. When the worm wheel 75 rotates, the transmission shaft 74 thereon can drive the main gear 73 to rotate, and then each driven gear 71 can rotate due to the action of the idler gear 72, and the steering direction is consistent. The driven gear 71 can drive the rod body 65 to rotate. When the rod body 65 rotates, it generates a threaded force with the axial pressure cylinder 62, causing the axial pressure cylinder 62 to undergo axial displacement (this displacement is very small), thereby squeezing the radial pressure cylinder 66.

[0041] When in use (when working), the device is lifted to the position of the charging pile to be detected by the handle 1, and the male lock 41 and the female lock 42 are opened, and then the box cover 22 is rotated to open the device. Since the traveling gear 13 can walk on the toothed track wheel 12 during the opening of the box cover 22, the traveling gear 13 can rotate, and the coaxial gear 77 can be driven to rotate during the rotation. When the coaxial gear 77 rotates, the worm 76 thereon can also rotate, thereby driving the worm wheel 75 to rotate. When the worm wheel 75 rotates, the transmission shaft 74 thereon can drive the main gear 73 to rotate, and then each driven gear 71 can rotate due to the action of the idler wheel 72. The driven gear 71 can drive the rod body 65 to rotate, and when the rod body 65 rotates, a threaded force is generated between it and the axial pressure cylinder 62, causing the axial pressure cylinder 62 to undergo an axial displacement, thereby causing the axial pressure cylinder 62 to move toward a side gradually away from the radial pressure cylinder 66, so that the radial pressure cylinder 66 loses pressure, causing it to lose pressure on the arc pressure plate 63, thereby greatly reducing the pressure of the arc pressure plate 63 on the adapter 5. At this time, the operator can easily take out any adapter 5. After taking it out, one end of the adapter 5 is plugged into the adapter female end 3, and the other end is plugged into the charging pile. At this time, it can be detected by the detector 8.

[0042] After the detection is completed, the adapter 5 and the adapter female end 3 can be returned to their positions, and the box cover 22 can be flipped over to close the box cover 22. During the closing process, the arc-shaped pressure plate 63 squeezes the adapter 5 so that the adapter 5 is locked in the positioning mechanism 6 to prevent the adapter 5 from falling off due to shaking when carrying the device.

[0043] Embodiment 2: See also Fig. 9 The difference between this embodiment and the first embodiment is that a rod body 65 is fixedly provided in the middle of the axial pressure cylinder 62 here, and the rod body 65 is a bare rod. When the rod body 65 is subjected to pressure, the axial pressure cylinder 62 can produce axial movement.

[0044] The transmission assembly here includes a steel wire rope transmission assembly 9 , and the steel wire rope transmission assembly 9 includes a moving plate 91 , a pressure structure 93 , a reel 96 , a guide wheel 95 , a steel wire rope body 94 and a spring 92 .

[0045] Among them, the movable plate 91 is located on the side of the box cover 22 away from the box body 21, the pressure structure 93 is fixed on the side of the movable plate 91 close to the positioning mechanism 6, and the position of the pressure structure 93 is opposite to the position of the rod body 65, the reel 96 is coaxial with the walking gear 13, and the guide wheel 95 is rotatably installed at the bottom of the box cover 22 through a bearing. One end of the wire rope body 94 is fixed on the lower end of the movable plate 91, and the other end of the wire rope body 94 is fixed on the reel 96. One end of the spring 92 is fixed on the movable plate 91, and the other end of the spring 92 is fixed on the top of the box cover 22.

[0046] In this embodiment, when the box cover 22 is closed, the traveling gear 13 travels and rotates on the toothed track wheel 12, thereby driving the winding wheel 96 to rotate, and then winding the wire rope body 94. When it is wound, it can pull the movable plate 91 downward, so that the movable plate 91 can move downward. In the process of the movable plate 91 moving downward, the pressure structure 93 can push the rod body 65, so that the axial pressure cylinder 62 undergoes axial displacement. In addition, the spring 92 is in the process of being gradually stretched at this time.

[0047] The pressure structure 93 mentioned above is a wedge-shaped block ( Fig. 9 and Fig.10 ) or a hinged rod 932 ( Fig.11 ), hinge seats 931 are assembled at both ends of the hinge rod 932.

[0048] The present invention also provides a method of use, which is applicable to the above-mentioned adapter plug assembly applicable to different charging pile detections, comprising the following steps: Step 1: Open the male lock 41 and the female lock 42, and rotate the box cover 22 along the pin shaft 10 to open the box cover 22. During the opening process of the box cover 22, the positioning mechanism 6 can be made to non-press the adapter 5 through the transmission assembly; Step 2: Turn on the detector 8, take out the female adapter 3, select a suitable adapter 5 according to the model of the charging pile and take the adapter 5 out of the positioning mechanism 6, plug one end of the adapter 5 into the female adapter 3, and plug the other end of the adapter 5 into the charging pile, and perform fault detection through the detector 8 until the detection is completed; Step three: return the adapter female end 3 and the adapter 5 to their original positions, and close the box cover 22. When closing the box cover 22, the positioning mechanism 6 is used to clamp the adapter 5 through the transmission structure to prevent the adapter 5 from falling off from the positioning mechanism 6.
