[0003] In order to enable the detection box to detect various models of charging piles, an adapter can be equipped. For the convenience of use, the existing adapter usually uses magnetic blocks to fix the adapter, and an iron ring needs to be assembled inside the adapter. Using this method will increase the weight of the adapter and is not convenient for the use of the adapter.

Detailed implementation manners

[0047] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0048] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships 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 thus should not be construed as a limitation to the present invention.

[0049] Next, according to Figures 1-11 describe the adapter plug assembly provided in the embodiment of the present invention for detecting different charging piles.

[0050] Embodiment 1:

[0051] Please refer to Figure 1 and Figure 2 As shown, the adapter plug assembly for detecting different charging piles in the embodiment of the present invention includes a box body 21. A pin shaft 10 is fixedly provided above one side of the box body 21. One side of the box cover 22 is rotatably installed on the pin shaft 10. The pin shaft 10 is fixed to the box body 21 through a shaft seat 101. Rotating the box cover 22 can make the box body 21 in an open or closed state. Preferably, a handle 1 is provided on one side of the box body 21 for convenient carrying of the device.

[0052] Preferably, a limit frame 11 is further provided on one side of the box body 21 close to the pin shaft 10 for restricting the excessive opening of the box cover 22.

[0053] As Figure 1 shown, a detector 8 is provided inside the box body 21. The detector 8 is used to detect the charging pile after being connected to the charging pile.

[0054] Continuing to refer to Figure 1 , an adapter 5 is also provided. The adapter 5 has at least two ( Figure 1 six adapters 5 are provided in the figure, and every three adapters 5 are in a row), and each adapter 5 is applicable to a different charging pile model, so that various models of charging piles can be used when the device detects the charging pile.

[0055] As Figures 3-6As shown, a positioning mechanism 6 is also provided. The positioning mechanism 6 is used to accommodate each adapter 5. Each positioning mechanism 6 is used to accommodate one adapter 5. The above-mentioned positioning mechanism 6 includes a fixed cylinder 61, which is fixed on the box cover 22 and has an accommodation space inside for accommodating the adapter 5.

[0056] In order to ensure that the adapter 5 can be in two states: being clamped or not being pressed (the non-pressed state also has a pressing force, but the pressure is less than the clamped state), the positioning mechanism 6 further includes a radial pressure cylinder 66, an arc-shaped pressing plate 63, and an axial pressure cylinder 62. The radial pressure cylinder 66 is located inside the fixed cylinder 61. The inner surface of the radial pressure cylinder 66 is an inclined surface, that is, its inner space is a conical structure. At least three groups of arc-shaped pressing plates 63 are provided. The outer surface of the arc-shaped pressing plate 63 is an inclined surface. The three groups of arc-shaped pressing plates 63 form a frustum-shaped structure (six arc-shaped pressing plates 63 are provided in the figure), and the arc-shaped pressing plate 63 is located on the inner wall of the radial pressure cylinder 66 and is defined to be able to move radially along the fixed cylinder 61. When the arc-shaped pressing plate 63 moves radially, it can press the adapter 5 to make the adapter 5 in a position-locked state; and the axial pressure cylinder 62 is located on the side of the arc-shaped pressing plate 63 away from the box body 21, and is used to apply an 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-shaped pressing plate 63 changes. When the relative position of the two inclined surfaces changes, the pressure of the radial pressure cylinder 66 on the arc-shaped pressing plate 63 will change, thereby adjusting the pressure of the arc-shaped pressing plate 63 on the adapter 5, which can be specifically adjusted to the pressed or non-pressed state. In the pressed state, the position of the adapter 5 is locked, and in the non-pressed state, the adapter 5 is convenient to be taken out from the positioning mechanism 6 for use.

[0057] In order to enable the above-mentioned positioning mechanism 6 to lock the position of the adapter 5 when the box cover 22 is in the closed state and not press the adapter 5 when the box cover is opened (this is because the adapter 5 is not needed in the closed state and is generally in the transportation state. Locking the position of the adapter 5 can prevent it from falling off; while in the opened state, the adapter 5 is in a waiting state for use. At this time, in the non-pressed state, the adapter 5 can be conveniently taken out from the positioning mechanism 6 without wear), a toothed track wheel 12 and a transmission assembly are also provided here. Figure 3 、 Figure 7 - Figure 9 As shown, the toothed track wheel 12 is fixed on the pin shaft 10. A traveling gear 13 that can mesh with the toothed track wheel 12 is provided inside the box cover 22, so that when the box cover 22 opens and closes along the pin shaft 10, the traveling gear 13 can rotate forward and backward. The transmission assembly is located inside the box cover 22 and is used to transmit the rotational force of the traveling gear 13 to the axial pressure cylinder 62 to form a state where the axial pressure cylinder 62 presses the radial pressure cylinder 66.

[0058] Therefore, the adapter plug assembly applicable to different charging piles provided by the embodiments of the present invention can make the positioning mechanism 6 not tightly press the adapter 5 through the action of opening the box cover 22. Conversely, it can make the positioning mechanism 6 clamp the adapter 5 through the action of closing the cover, thereby avoiding the collision damage caused by the detachment of the adapter 5 during transportation.

[0059] Preferably, in order to facilitate the installation of the toothed track wheel 12 and the walking gear 13, a receiving box 222 is further provided on the box cover 22, and notches 221 are provided below the receiving box 222 and below the box cover 22.

[0060] Preferably, a female lock 42 is provided on one side of the box body 21 away from the pin shaft 10, and a male lock 41 is provided on one side of the box cover 22 away from the pin shaft 10. The male lock 41 is latched with the female lock 42 for locking the box cover 22 on the box body 21. And due to the latching of the male lock 41 and the female lock 42, it can further ensure the position locking of the axial pressure cylinder 62 by the transmission mechanism.

[0061] In order to ensure that the arc-shaped pressing plate 63 can only move radially when it is subjected to the pressure of the radial pressure cylinder 66, a first guiding block 631 is fixedly provided on the outer surface of the arc-shaped pressing plate 63 along the radial direction. An avoidance groove 661 is formed in the area of the radial pressure cylinder 66 opposite to the first guiding block 631, and a first limiting groove 611 is formed in the area of the fixed cylinder 61 opposite to the radial pressure cylinder 66. The first guiding block 631 can move radially in the first limiting groove 611. When the radial pressure cylinder 66 is subjected to the axial pressure from the axial pressure cylinder 62, Figure 4 in the shown perspective, the radial pressure cylinder 66 can move to the left. When it moves to the left, it can generate an axial and a radial component force on the arc-shaped pressing plate 63. However, due to the limiting effect of the first guiding block 631, the arc-shaped pressing plate 63 can press the adapter 5 radially.

[0062] Preferably, the axial length of the above avoidance groove 661 is greater than the axial length of the first guiding block 631 to provide a moving space for the axial movement of the radial pressure cylinder 66.

[0063] As Figure 4 and Figure 6 , in order to ensure that the arc-shaped pressing plate 63 does not fall off the radial pressure cylinder 66 in the state where the adapter 5 is not inserted, a limiting rod 663 is fixedly provided in the avoidance groove 661, and a through hole 632 is provided on the first guiding block 631. The limiting rod 663 passes through the through hole 632, so that the arc-shaped pressing plate 63 can be limited on the radial pressure cylinder 66. Preferably, the diameter of the through hole 632 is greater than the diameter of the limiting rod 663.

[0064] As Figure 5 and Figure 6, To facilitate prompting the operator of the maximum threshold for inserting 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 block the continuous insertion of the adapter 5, 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 relief groove 621 for accommodating the positioning rod 641 is provided on the axial pressure cylinder 62, and the axial length of the relief groove 621 is greater than the length of the positioning rod 641 along the axis of the fixed cylinder 61, so as to prevent the positioning rod 641 from blocking the axial movement of the axial pressure cylinder 62.

[0065] Preferably, the positioning rod 641 should be inserted into the inner wall of the fixed cylinder 61, and a second limiting groove 612 adapted to the positioning rod 641 is provided on the inner wall of the fixed cylinder 61.

[0066] Preferably, a guiding portion 613 is provided at the insertion port of the fixed cylinder 61. The inner diameter of the guiding portion 613 is relatively small, which can guide the inserted adapter 5 and prevent the adapter 5 from falling off the positioning mechanism 6 when the arc-shaped pressing plate 63 has not yet pressed the adapter 5 tightly during the process of closing the cover.

[0067] As Figure 1 , preferably, a receiving hole is provided in the box body 21, a female adapter 3 is provided in the receiving hole, and a wire connected to the detector 8 is provided on the female adapter 3. When it is necessary to detect the charging pile, the female adapter 3 is taken out from the receiving hole, and then the adapter 5 adapted to the charging pile is taken out, and one end of the adapter 5 is connected to the female adapter 3, and the other end is inserted into the charging pile to perform the detection.

[0068] Combined Figure 3 、 Figure 7 and Figure 8 As shown, specifically, to achieve the transmission effect of the above transmission component, a rod body 65 (with threads on the rod body 65) is installed in the middle of the axial pressure cylinder 62 through threads. The rotation of the rod body 65 can cause the axial pressure cylinder 62 to move axially; and the transmission component includes a gear transmission component 7, and the gear transmission component 7 includes a driven gear 71, an idler gear 72, a main gear 73, a coaxial gear 77 and a worm 76.

[0069] 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 lowermost driven gear 71, one side of the traveling gear 13 is meshed with the toothed track wheel 12, 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, and a worm gear 75 is meshed above the worm 76. A transmission shaft 74 is fixed between the worm gear 75 and the main gear 73.

[0070] In this implementation, when the lid 22 is closed, the traveling gear 13 travels 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 gear 75 to rotate. When the worm gear 75 rotates, the transmission shaft 74 thereon can drive the main gear 73 to rotate. Subsequently, each driven gear 71 can rotate due to the action of the idler gear 72, and the steering directions are the same. The driven gear 71 can drive the rod 65 to rotate. When the rod 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 (this displacement is very small), thereby squeezing the radial pressure cylinder 66.

[0071] During use (operation), lift this device to the position of the charging pile to be detected through the handle 1. Open the male lock 41 and the female lock 42, and then rotate the lid 22 to open this device. Since the traveling gear 13 can travel on the toothed track wheel 12 during the opening process of the lid 22, the traveling gear 13 can rotate on its own. During its rotation, it can drive the coaxial gear 77 to rotate. When the coaxial gear 77 rotates, the worm 76 thereon can also rotate, thereby driving the worm gear 75 to rotate. When the worm gear 75 rotates, the transmission shaft 74 thereon can drive the main gear 73 to rotate. Subsequently, each driven gear 71 can rotate due to the action of the idler gear 72, and the steering directions are the same. The driven gear 71 can drive the rod 65 to rotate. When the rod 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, so that the axial pressure cylinder 62 moves toward the side gradually away from the radial pressure cylinder 66. As a result, the radial pressure cylinder 66 loses pressure, causing it to also lose pressure on the arc-shaped pressing plate 63. Thus, the pressure of the arc-shaped pressing plate 63 on the adapter 5 is greatly reduced. At this time, the operator can conveniently take out any adapter 5. After taking it out, one end of the adapter 5 is inserted into the female adapter 3, and the other end is inserted into the charging pile. At this time, detection can be performed through the detector 8.

[0072] After the detection is completed, the adapter 5 and the female adapter 3 can be returned to their positions, and the lid 22 is flipped to close the lid 22. During its closing process, the arc-shaped pressing plate 63 presses the adapter 5, locking the adapter 5 in the positioning mechanism 6 to avoid the situation of the adapter 5 falling off due to shaking when carrying this device.

[0073] Embodiment 2:

[0074] Refer to Figure 9 , the difference between this embodiment and Embodiment 1 is that a rod 65 is fixedly provided in the middle of the axial pressure cylinder 62 here. The rod 65 is a smooth rod, and when the rod 65 is subjected to pressure, it can cause the axial pressure cylinder 62 to move axially.

[0075] 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 winding wheel 96, a guide wheel 95, a main steel wire rope 94, and a spring 92.

[0076] Among them, the moving 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 moving 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 winding wheel 96 is coaxial with the traveling gear 13. The guide wheel 95 is rotatably installed below the box cover 22 through a bearing. One end of the main steel wire rope 94 is fixed to the lower end of the moving plate 91, and the other end of the main steel wire rope 94 is fixed on the winding wheel 96. One end of the spring 92 is fixed on the moving plate 91, and the other end of the spring 92 is fixed above the box cover 22.

[0077] In this implementation, 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 main steel wire rope 94. When winding, it can pull the moving plate 91 downward, so that the moving plate 91 can move downward. During the downward movement of the moving plate 91, the pressure structure 93 can push the rod body 65, causing the axial pressure cylinder 62 to have an axial displacement. In addition, at this time, the spring 92 is in the process of being gradually stretched.

[0078] The above-mentioned pressure structure 93 is a wedge block ( Figure 9 and Figure 10 ) or a hinged rod 932 hinged between the moving plate 91 and the axial pressure cylinder 62 ( Figure 11 ), and hinge seats 931 are assembled at both ends of the hinged rod 932.

[0079] The present invention also provides a usage method, which is applicable to the above-mentioned adapter plug assembly for different charging pile detections, and includes the following steps:

[0080] 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-compress the adapter 5 through the transmission assembly;

[0081] Step 2: Open the detector 8, take out the female adapter 3, select a suitable adapter 5 according to the model of the charging pile, take out the adapter 5 from the positioning mechanism 6, insert one end of the adapter 5 into the female adapter 3, insert the other end of the adapter 5 into the charging pile, and perform fault detection through the detector 8 until the detection is completed;

[0082] Step 3: Return the female adapter 3 and the adapter 5 to their positions, and close the box cover 22. When closing the box cover 22, the positioning mechanism 6 can be made to clamp the adapter 5 through the transmission structure to prevent the adapter 5 from falling off the positioning mechanism 6.
