[0029] Reference Figures 1-6 In the example embodiment, the locking structure can include a first plate 1, a second plate 2, a first elastic sheet 3, a second elastic sheet 4, and a limiting portion. The first plate 1 has a first through hole 11. The second plate 2 is arranged opposite to the first plate 1 in a first direction, and has a second through hole 21 arranged thereon, which is opposite to the first through hole 11 in the first direction. The first direction is the same as the thickness direction of the first plate 1. The first elastic sheet 3 is connected to the first plate 1 at a first end and passes through the second through hole 21 at a second end. The second elastic sheet 4 is elastically connected to the second end of the first elastic sheet 3 at one end and passes through the first through hole 11 and the second through hole 21 at the other end. The limiting portion is connected to a side of the second elastic sheet 4 and located on a side of the second plate 2 away from the first plate 1. When the second elastic sheet 4 is in an initial state, the limiting portion is opposite to the second plate 2.

[0030] The locking structure proposed in the embodiment of the present application can be used to separate the first plate 1 and the second plate 2. The operator pushes the second elastic sheet 4 to rotate. The second elastic sheet 4 changes from the initial state to the compressed state. At this time, the limiting portion is opposite to the second through hole 21 in the first direction. Therefore, the limiting portion can pass through the second through hole 21 in the first direction, so as to separate the first plate 1 and the second plate 2. Then, the second elastic sheet 4 is released. The elastic connection between the second elastic sheet 4 and the first elastic sheet 3 provides a resilient elastic force for the second elastic sheet 4, so that the second elastic sheet 4 changes from the compressed state to the initial state. When the first plate 1 is connected to the second plate 2, the operator pushes the second elastic sheet 4 to rotate. The second elastic sheet 4 changes from the initial state to the compressed state. At this time, the limiting portion is opposite to the second through hole 21 in the first direction. Therefore, the limiting portion can pass through the second through hole 21 in the first direction, so as to connect the first plate 1 and the second plate 2. Then, the second elastic sheet 4 is released. The elastic connection between the second elastic sheet 4 and the first elastic sheet 3 provides a resilient elastic force for the second elastic sheet 4, so that the second elastic sheet 4 changes from the compressed state to the initial state. At this time, the limiting portion is opposite to the edge of the second through hole 21 in the first direction. Therefore, the limiting portion cannot pass through the second through hole 21 in the first direction, so as to prevent the first plate 1 and the second plate 2 from sliding in the first direction. The first plate 1 is installed on the charging module 8, and the second plate 2 is installed on the cabinet frame 7. In this way, the first plate 1 and the second plate 2 are clamped and matched to fix the charging module 8, instead of the traditional bolt connection. The efficiency of disassembling the charging module 8 is greatly improved, and the maintenance is convenient.

[0031] Specifically, as Figure 1 and Figure 2As shown, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction. The second direction is the same as the width direction of the second elastic sheet 4, and the third direction is perpendicular to the second direction and the first direction. The second elastic sheet 4 rotates, that is, the second elastic sheet 4 rotates around the region where the second elastic sheet 4 is elastically connected to the first elastic sheet 3, or it can be understood that the second elastic sheet 4 rotates around the second direction.

[0032] It should be understood that, in the absence of an external force, the second elastic sheet 4 is in an initial state, and there is no elastic force between the second elastic sheet 4 and the first elastic sheet 3. When the second elastic sheet 4 is subjected to an external force, the second elastic sheet 4 rotates, and the end of the second elastic sheet 4 away from the first elastic sheet 3 gradually approaches the first elastic sheet 3. At this time, the angle between the first elastic sheet 3 and the second elastic sheet 4 gradually decreases, so that the second elastic sheet 4 is in a compressed state, and the elastic connection region between the second elastic sheet 4 and the first elastic sheet 3 generates an elastic force. At this time, if the external force disappears, the second elastic sheet 4 changes from the compressed state to the initial state under the action of the elastic force.

[0033] Further, the second elastic sheet 4 and the first elastic sheet 3 can be an integral structure. When connecting and separating the first plate 1 and the second plate 2, in other words, when installing and separating the charging module 8 and the cabinet frame 7, no additional tools are needed to turn the screws in the traditional scheme, so the operation efficiency is high. And the cabinet frame 7 does not need to be provided with a nut that is difficult to maintain, and the overall maintenance cost is lower.

[0034] It should be noted that the external driving force is the same as the above-mentioned external force, that is, the force of the operator turning the second elastic sheet 4, and the force point is located at the end of the second elastic sheet 4 away from the first elastic sheet 3.

[0035] Reference Figure 1 With Figure 2 In an exemplary embodiment, the first elastic sheet 3, the second elastic sheet 4, the first through hole 11, and the second through hole 21 form an elastic structure, and there are at least two elastic structures, and the at least two elastic structures are spaced apart from each other.

[0036] Specifically, the more the number of elastic structures, the more stable the connection between the first plate 1 and the second plate 2.

[0037] As Figure 1 shown, the elastic structure has two and is oppositely arranged in the third direction, and the third direction is parallel to the first plate 1. Among them, the two first elastic sheets 3 are located between the two second elastic sheets 4.

[0038] Specifically, when the first plate 1 and the second plate 2 need to be separated, both of the second elastic sheets 4 need to be changed from the initial state to the compressed state, and then the operator can push the two second elastic sheets 4 close to each other with one hand, so as to change the two second elastic sheets 4 from the initial state to the compressed state, and the operation is more convenient.

[0039] Reference Figure 3 In the example embodiment, the locking structure can further include a connecting sheet 6 connected to the side of the first plate 1 facing the first elastic sheet 3, and both ends of the connecting sheet 6 are connected to a first elastic sheet 3.

[0040] Specifically, both of the first elastic sheets 3 are fixed to the first plate 1 through the connecting sheet 6; and the connecting sheet 6 can be fixed to the first plate 1 by welding, riveting or screw connection.

[0041] In addition, as shown in Figure 3 , the five components of the connecting sheet 6, the two first elastic sheets 3 and the two second elastic sheets 4 can be an integrated elastic assembly, and the cross section of the elastic assembly perpendicular to the second direction is similar to M-shaped, so that the elastic assembly can be made by bending the elastic sheet, and the manufacturing is simpler; and only the part of the elastic assembly corresponding to the two second elastic sheets 4 needs to pass through the corresponding first through hole 11, and then the part of the elastic assembly corresponding to the connecting sheet 6 is connected to the first plate 1, so as to complete the assembly of the five components of the connecting sheet 6, the two first elastic sheets 3 and the two second elastic sheets 4, and the operation is convenient and fast.

[0042] Reference Figure 3 In the example embodiment, when the second elastic sheet 4 is in the initial state, the extension direction of the second elastic sheet 4 is the same as the first direction. In this way, the included angle between the second elastic sheet 4 and the first elastic sheet 3 is necessarily acute, and at this time the overall locking structure occupies less space.

[0043] Reference Figure 3 With Figure 4 In the example embodiment, when the second elastic sheet 4 is in the initial state, there is a gap between the limiting portion and the second plate 2.

[0044] As shown in Figure 3 and Figure 4 , at this time the second elastic sheet 4 is in the initial state, and there is a gap between the limiting portion and the second plate 2, so when the end of the second elastic sheet 4 away from the first elastic sheet 3 is actuated to change the second elastic sheet 4 to the compressed state as shown in Figure 4 , the limiting portion will not be in contact with the second plate 2, so as to ensure that the rotation process of the second elastic sheet 4 can be smoothly carried out.

[0045] In addition, the second elastic sheet 4 is not capable of being changed from the initial state to the compressed state at any rotation angle. In the embodiment, the rotation angle of the second elastic sheet 4 from the initial state to the compressed state is a, and 18°≤a≤25°. The value of a can be 18°, 20°, 22°, 25°, or the like.

[0046] It should be understood that when the second elastic sheet 4 is changed from the initial state to the compressed state, the included angle between the second elastic sheet 4 and the first elastic sheet 3 decreases. When the second elastic sheet 4 is changed from the compressed state to the initial state, the included angle between the second elastic sheet 4 and the first elastic sheet 3 increases.

[0047] With reference to Figure 3 , the end of the second elastic sheet 4 away from the first elastic sheet 3 is provided with a bending portion.

[0048] The cross section of the bending portion perpendicular to the second direction is in a U shape. The U-shaped bending portion has an open end and an arc-shaped closed end opposite to the open end in the extension direction of the second elastic sheet 4. The open end of the U-shaped bending portion faces the first plate 1.

[0049] When the operator moves the end of the second elastic sheet 4 away from the first elastic sheet 3, as shown in Figure 3 , the palm of the operator can be in contact with the arc-shaped closed end of the U-shaped bending portion, thereby effectively improving the pressing comfort.

[0050] Further, as shown in Figure 3 , the second elastic sheet 4 has a stepped inclined surface in the open end region of the U-shaped bending portion. Thus, the operator can press the inclined surface region to reduce the included angle between the first elastic sheet 3 and the second elastic sheet 4. Thus, the stepped inclined surface in the extension direction of the second elastic sheet 4 can provide a certain resistance to prevent the relative sliding between the fingers and the second elastic sheet 4 during the pressing process. Figure 3

[0051] It should be noted that the cross section of the bending portion perpendicular to the second direction is in a U shape, which is only an example and is not limited. For example, the cross section of the bending portion perpendicular to the second direction can also be in a circular arc shape or a wave shape. As long as the palm of the operator can be in contact with the arc-shaped structure on the bending portion when the operator moves the end of the second elastic sheet 4 away from the first elastic sheet 3, the pressing comfort can be effectively improved.

[0052] ​Specifically, when the cross section of the bending part perpendicular to the second direction is a circular arc type, when the operator moves the second elastic sheet 4 away from one end of the first elastic sheet 3, the palm will contact the arc surface structure of the circular arc type bending part, thereby effectively improving the pressing comfort level; when the cross section of the bending part perpendicular to the second direction is a circular wave, when the operator moves the second elastic sheet 4 away from one end of the first elastic sheet 3, the palm will contact the wave-shaped structure of the wave-shaped bending part, thereby effectively improving the pressing comfort level.

[0053] Reference Figure 2 With Figure 3 In an exemplary embodiment, the limiting part can include two limiting blocks 5, which are oppositely arranged in the second direction, and the side of the limiting block 5 facing the second plate 2 is a straight side, and the side away from the second plate 2 is an inclined side, and the second direction is the same as the width direction of the second elastic sheet 4; wherein, when the second elastic sheet 4 is in the initial state, in the first direction, the inclined side is opposite to the edge of the second through hole 21.

[0054] Specifically, the limiting block 5 has opposite inclined side and straight side, and when the second elastic sheet 4 is in the initial state, as shown in Figure 3 , the straight side is opposite to the edge of the second through hole 21, and the straight side is located on the side of the limiting block 5 facing the second plate 2, so that when the second plate 2 is connected with the first plate 1, the limiting block 5 can prevent the second plate 2 from being separated from the first plate 1;

[0055] At the same time, as shown in Figure 3 , the inclined side is also opposite to the edge of the second through hole 21 in the first direction, so that when connecting the first plate 1 and the second plate 2, if the second plate 2 is fixed, the first plate 1 can be moved in the first direction to make the first plate 1 close to the second plate 2, and part of the structure of the first elastic sheet 3 and the second elastic sheet 4 gradually passes through the second through hole 21, and the inclined side will be in contact with the second through hole 21, at this time, if the first plate 1 is continuously pushed in the first direction, the second plate 2 will be extruded on the inclined side through the edge of the second through hole 21, thereby pushing the second elastic sheet 4 to rotate, so that the second elastic sheet 4 changes from the initial state to the compressed state, and when the limiting block 5 completely passes through the second through hole 21, the second elastic sheet 4 rebounds, changes from the compressed state to the initial state. Therefore, when connecting the first plate 1 and the second plate 2, it is not necessary to manually move the second elastic sheet 4, but only needs to push the first plate 1 in the first direction to close to the second plate 2 to complete the connection of the first plate 1 and the second plate 2.

[0056] Specifically, when the first plate 1 is connected with the charging module 8, and the second plate 2 is connected with the cabinet frame 7, the charging module 8 is pushed in the first direction, thereby completing the connection of the first plate 1 and the second plate 2, which is more convenient and faster than the traditional connection by bolts.

[0057] refer to Figure 3 In an exemplary embodiment, the portions of the first elastic sheet 3 and the second elastic sheet 4 located on the side of the second plate 2 away from the first plate 1 are the first mating portion and the second mating portion; the projections of the first mating portion and the second mating portion on the second plate 2 along the first direction are both located on the inner periphery of the edge of the second through hole 21 and are spaced apart from the edge of the second through hole 21.

[0058] Specifically, it should be understood that when the first plate 1 is connected to the second plate 2, parts of the structure of both the first elastic sheet 3 and the second elastic sheet 4 are located on the side of the second plate 2 away from the first plate 1, and are respectively referred to as the first mating part and the second mating part.

[0059] like Figure 3 As shown, the projections of the first mating part and the second mating part on the second plate 2 along the first direction are both located on the inner periphery of the edge of the second through hole 21 and are spaced apart from the edge of the second through hole 21. That is to say, the size of the second through hole 21 is slightly larger. When connecting the first plate 1 and the second plate 2, even if the position of the first plate 1 is slightly deviated, parts of the structure of both the first elastic piece 3 and the second elastic piece 4 can pass through the second through hole 21 relatively easily, ensuring the stable use of the locking structure.

[0060] Specifically, after the first plate 1 is connected to the charging module 8 and the second plate 2 is connected to the cabinet frame 7, the slightly larger size of the second through hole 21 can provide sufficient tolerance margin, ensuring that when the charging module 8 is pushed into the cabinet frame 7, parts of the first elastic piece 3 and the second elastic piece 4 can easily pass through the second through hole 21, ensuring that the first plate 1 and the second plate 2 can be stably connected. This prevents the situation in traditional solutions where, due to dimensional tolerances, the screw and nut holes cannot be aligned in the center when installing multiple modules, thus making it impossible to install the equipment.

[0061] refer to Figure 5 and Figure 6 Based on the above embodiments, this application also provides a charging pile, which may include a cabinet frame 7, the above-mentioned locking structure and a charging module 8, wherein the charging module 8 is slidably connected to the cabinet frame 7 and has a degree of freedom to slide in a first direction, wherein a first plate 1 is disposed on the charging module 8 and a second plate 2 is disposed on the cabinet frame 7 to lock or release the sliding degree of freedom of the charging module 8.

[0062] Specifically, such as Figure 5 and Figure 6As shown, the charging pile includes a cabinet frame 7 and a charging module 8. The third direction is the same as the height direction of the cabinet frame 7. The cross section of the cabinet frame 7 perpendicular to the third direction is U-shaped. The cabinet frame 7 has an open end and a closed end. The charging module 8 is pushed into the cabinet frame 7 from the open end along the first direction.

[0063] The charging module 8 has a cable terminal on the side near the closed end, and the cabinet frame 7 also has a terminal 71 at the closed end, so that when the charging module 8 is pushed into the cabinet frame 7 in the first direction, the cable terminal and the terminal 71 can be plugged and connected.

[0064] In addition, there can be multiple charging modules 8, which can be arranged sequentially in a third direction.

[0065] Specifically, the side of the charging module 8 that faces away from the closed end is designated as the front side, such as... Figure 5 and Figure 6 As shown, the first plate 1 can be set on the front outer periphery of the charging module 8; the second plate 2 is set on the column of the cabinet frame 7. The front outer periphery of the charging module 8 is opposite to the column of the cabinet frame 7 in the first direction. In this way, when the charging module 8 is pushed into the cabinet frame 7, the first plate 1 moves closer to the second plate 2 in the first direction, and the first plate 1 and the second plate 2 can be connected according to the above scheme, that is, the charging module 8 and the cabinet frame 7 are connected. Disassembling the charging module 8 is to separate the first plate 1 and the second plate 2.

[0066] In a preferred embodiment, such as Figure 5 and Figure 6 As shown, the front of the first plate 1 and the charging module 8 can be an integral structure, meaning that a first through hole 11 can be directly opened on the front of the charging module 8, opposite to the column in the first direction, so that the front of the charging module 8 can be used as the first plate 1; of course, the column can also be an integral structure with the second plate 2, and the column can be a hollow column. In the first direction, a second through hole 21 can be directly opened on the side of the column facing the front of the charging module 8, so that the side of the column with the second through hole 21 can be used as the second plate 2; as shown. Figure 5 In the column shown, it can be understood that multiple second plates 2 are connected sequentially in the third direction, that is, multiple second through holes 21 are opened on the column along the third direction, which correspond one-to-one with all the first through holes 11 on the front side of each charging module 8.

[0067] Among them, such as Figure 5 and Figure 6As shown, there can be multiple first plates 1 on a single charging module 8. If the above-mentioned scheme of having only one first through hole 11 on the first plate 1 is implemented, then there can be four first plates 1 on a single charging module 8, which are located near the four corners of the charging module 8. The number of first plates 1 here is only a preferred scheme and can be changed according to different material strengths.

[0068] If implemented according to the above-mentioned scheme with two first through holes 11 on the first plate 1, then as follows Figure 5 and Figure 6 The single charging module 8 shown has two first plates 1. Similarly, the number of first plates 1 here is only a preferred option and can be changed according to different material strengths.

[0069] Furthermore, such as Figure 5 As shown, the first plate 1 is mainly distributed on both sides of the charging module 8 in the second direction. Of course, the first plate 1 can also be set on both sides of the charging module 8 in the third direction. It is only necessary to add a crossbeam similar to a column between each charging module 8 to cooperate with the first plate 1.

[0070] It should be understood that there are many traditional solutions for how the charging module 8 slides and connects with the cabinet frame 7 in the first direction, which will not be explained in detail here.

[0071] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
