[0051] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0052] The first aspect of the present application provides a clamp assembly 10, which is used for taking and placing an electric energy meter. The clamp assembly 10 has good compatibility and can guarantee the grabbing efficiency of the electric energy meter. The electric energy meter includes a first electric meter and a second electric meter. It should be noted that the first electric meter includes at least one of a single-phase electric meter, a three-phase electric meter, a terminal electric meter and an electric meter module (a battery module or a shell module, etc.), and the second electric meter includes at least one of a single-phase electric meter, a three-phase electric meter, a terminal electric meter and an electric meter module (a battery module or a shell module, etc.). The present application takes the first electric meter as an electric meter module and the second electric meter as a single-phase electric meter as an example for description.

[0053] The clamp assembly 10 of the present application will be described below with reference to Figures 1 to 5 . Specifically, the clamp assembly 10 includes a base body 100, a first grabbing part 200 and a second grabbing part 300. The base body 100 is used for connecting the first grabbing part 200 and the second grabbing part 300. The specific structure and shape of the base body 100 can be determined according to actual conditions. The present application takes the base body 100 as a rectangular plate as an example for description.

[0054] With reference to Figures 1 to 3 , the first grabbing part 200 is used for grabbing the first electric meter, that is, the structure of the first grabbing part 200 can be adapted to the arrangement of the first electric meter. The present application takes the first grabbing part 200 for grabbing an electric meter module as an example for description. It can be understood that the first grabbing part 200 can grab the first electric meter at a feeding position and can release the first electric meter to a discharging position after the movement of the clamp assembly 10. It should be noted that the first grabbing part 200 can be connected to the base body 100. The first grabbing part 200 includes a first clamping part 210 and a second clamping part 220. The first clamping part 210 can be arranged apart from the second clamping part 220. In order to facilitate the description and understanding of the movement and grabbing direction of the first clamping part 210 and the second clamping part 220, a first direction X is defined. The first clamping part 210 can be relatively close to the second clamping part 220 along the first direction X to grab the first electric meter. With reference to Figure 1 the orientation, the first direction X can point to the front-back direction.

[0055] With reference to Figure 1 , Figure 2 and Figure 4The second grabbing part 300 is used for grabbing the second electric meter, that is, the structure of the second grabbing part 300 can be adapted to the arrangement of the second electric meter. The embodiments of the present application take the second grabbing part 300 used for grabbing the single-phase electric meter as an example for description. It can be understood that the second grabbing part 300 can grab the second electric meter at the feeding position, and the second electric meter can be released to the discharging position through the movement operation of the clamp assembly 10. The second grabbing part 300 is movably connected with the base body 100. The second grabbing part 300 comprises a third clamping part 310 and a fourth clamping part 320. The third clamping part 310 can be arranged in a spaced manner with the fourth clamping part 320. The third clamping part 310 and the fourth clamping part 320 can relatively approach along the first direction X to grab the second electric meter. For reference Figure 1 The first direction X can refer to the front-back direction. When the movement grabbing direction of the first grabbing part is perpendicular to the movement grabbing direction of the second grabbing part, the first grabbing part and the second grabbing part will interfere with each other when they synchronously perform the grabbing operation, resulting in abnormality of the grabbing operation. The first clamping part 210 and the second clamping part 220 of the present solution can relatively approach along the first direction X to grab the first electric meter, and the third clamping part 310 and the fourth clamping part 320 can relatively approach along the first direction X to grab the second electric meter, that is, the movement grabbing direction of the first grabbing part 200 and the movement grabbing direction of the second grabbing part 300 are the same. Therefore, the present solution can effectively avoid the situation that the first grabbing part 200 and the second grabbing part 300 synchronously grab, thereby improving the stability and reliability of the electric meter taking and releasing.

[0056] For the convenience of description and understanding of the relative arrangement position of the second grabbing part 300 and the first grabbing part 200, a second direction Y is defined. The second grabbing part 300 and the first grabbing part 200 are arranged in a relative manner along the second direction Y, and the second direction Y is arranged in a cross manner with the first direction X. Specifically, the second direction Y can be perpendicular to the first direction X, or can be in other inclined angles which are not perpendicular. The embodiments of the present application take the second direction Y perpendicular to the first direction X as an example for description. For reference Figure 1 That is, the second grabbing part 300 can be arranged in a relative manner with the first grabbing part 200 along the left-right direction.

[0057] The second grabbing part 300 and the first grabbing part 200 have a first relative position and a second relative position. In the first relative position, the second grabbing part 300 and the first grabbing part 200 at least partially coincide along the second direction Y, in other words, the first grabbing part 200 and the second grabbing part 300 are in the same position along the second direction Y, that is, the clamp assembly 10 can simultaneously grab the first electric meter and the second electric meter. In the second relative position, the second grabbing part 300 and the first grabbing part 200 are at least partially spaced along the second direction Y, in other words, the second grabbing part 300 and the first grabbing part 200 are arranged in a staggered manner. It can be understood that the second grabbing part 300 can be moved relative to the base body 100 to switch between the first relative position and the second relative position.

[0058] In the technical scheme of the utility model, the clamp assembly 10 is used for taking and placing the electric energy meter, and the electric energy meter comprises a first electric meter and a second electric meter. The clamp assembly 10 comprises a base body 100, a first grabbing part 200 and a second grabbing part 300. The first grabbing part 200 is connected with the base body 100, and the second grabbing part 300 is movably connected with the base body 100 and oppositely arranged with the first grabbing part 200 along a second direction Y. In the prior art, the clamp assembly can only adapt to a single electric energy meter, so that the clamp assembly needs to be frequently replaced when the type of electric energy meter is switched, that is, the feeding and discharging operation of the electric energy meter is complicated, resulting in low efficiency of the electric energy meter calibration. The first grabbing part 200 of the present scheme can grab the first electric meter, and the second grabbing part 300 can grab the second electric meter, that is, the clamp assembly 10 of the present scheme has good compatibility and can adapt to various electric energy meters, so that the replacement operation of the clamp assembly 10 can be omitted and the calibration efficiency is improved.

[0059] When the clamp assembly comprises a right-angle plate, a first grabbing part and a second grabbing part, the first grabbing part and the second grabbing part are respectively connected with two ends of the right-angle plate, the clamp assembly needs to be rotated to make the first grabbing part face the first electric meter when the first electric meter is grabbed, and the clamp assembly needs to be rotated to make the second grabbing part face the second electric meter when the second electric meter is grabbed, that is, the clamp assembly can only grab a single type of electric energy meter at a time. The first grabbing part 200 and the second grabbing part 300 of the clamp assembly 10 of the present scheme at least partially overlap along the second direction Y in the first relative position, that is, the first grabbing part 200 and the second grabbing part 300 are in the same position along the second direction Y, so that the clamp assembly 10 can simultaneously grab the first electric meter and the second electric meter, effectively improving the feeding and discharging efficiency of the electric energy meter and omitting the switching operation of the clamp assembly 10.

[0060] Further, when the first electric meter and the second electric meter are placed at a close distance and the first electric meter or the second electric meter is close to the external blocking edge, the clamp assembly 10 can be in the second relative position, the second grabbing part 300 and the first grabbing part 200 are at least partially spaced apart along the second direction Y, that is, the second grabbing part 300 and the first grabbing part 200 can be arranged in a staggered manner. Therefore, the present scheme can effectively avoid the situation that the first grabbing part 200 and the second grabbing part 300 interfere with each other and the clamp assembly 10 interferes with the external blocking edge, and ensure the stability and reliability of the electric energy meter taking and placing.

[0061] Referring to Figure 1 , Figure 2 and Figure 5In some embodiments, the electric energy meter includes a third electric meter, and the clamp assembly 10 includes a third grabbing part 400 for grabbing the third electric meter. The third electric meter includes at least one of a single-phase electric meter, a three-phase electric meter, a terminal electric meter, and an electric meter module (a battery module or a shell module, etc.). The embodiments of the present application take the third electric meter as a three-phase electric meter or a terminal electric meter as an example for description. The third grabbing part 400 is oppositely arranged with the second grabbing part 300 along the second direction Y and is located on the side of the second grabbing part 300 away from the first grabbing part 200. For reference Figure 1 In the orientation, the third grabbing part 400 is located on the right side of the second grabbing part 300, and the first grabbing part 200 is located on the left side of the second grabbing part 300. It can be understood that the third grabbing part 400 is connected with the base body 100. The third grabbing part 400 includes a fifth clamping part 410 and a sixth clamping part 420, and the fifth clamping part 410 and the sixth clamping part 420 are arranged at intervals. The fifth clamping part 410 and the sixth clamping part 420 can be oppositely close along the first direction X to grab the third electric meter. For reference Figure 1 In the orientation, the first direction can refer to the front-back direction.

[0062] The third grabbing part 400 and the second grabbing part 300 have a third relative position and a fourth relative position. In the third relative position, the third grabbing part 400 and the second grabbing part 300 at least partially coincide along the second direction Y, in other words, the third grabbing part 400 and the second grabbing part 300 are in the same position along the second direction Y, that is, the clamp assembly 10 can simultaneously grab the second electric meter and the third electric meter. In the fourth relative position, the third grabbing part 400 and the second grabbing part 300 are at least partially spaced apart along the second direction Y, in other words, the second grabbing part 300 and the third grabbing part 400 are arranged in a staggered manner. It can be understood that the second grabbing part 300 is movable relative to the base body 100 to switch between the second relative position and the third relative position.

[0063] When the clamp assembly 10 is in the third relative position, the second grabbing part 300 and the third grabbing part 400 at least partially coincide along the second direction Y, that is, the second grabbing part 300 and the third grabbing part 400 are in the same position along the second direction Y, so that the clamp assembly 10 can simultaneously grab the first electric meter and the second electric meter, effectively improving the feeding and discharging efficiency of the electric energy meter and omitting the switching operation of the clamp assembly 10. When the second electric meter and the third electric meter are placed close to each other and the second electric meter or the third electric meter is close to the external blocking edge, the clamp assembly 10 can be in the fourth relative position, and the second grabbing part 300 and the third grabbing part 400 are at least partially spaced apart along the second direction Y, that is, the second grabbing part 300 and the third grabbing part 400 can be arranged in a staggered manner. Therefore, the present application can effectively avoid the situation that the second grabbing part 300 and the third grabbing part 400 interfere with each other and the clamp assembly 10 interferes with the external blocking edge, thereby ensuring the stability and reliability of the electric energy meter taking and placing.

[0064] With reference to Figure 1 and Figure 2 , the specific connection of the first grabbing part 200 and the base 100 is introduced as follows. In some embodiments, the first grabbing part 200 and the second grabbing part 300 are movably connected to the base 100 to realize the switching between the first relative position and the second relative position. In other embodiments, the first grabbing part 200 is fixedly connected to the base 100, and the second grabbing part 300 is movably connected to the base 100, i.e., the position switching is realized by the movement of the second grabbing part 300 relative to the base 100. The embodiments of the present application are described by taking the example that the first grabbing part 200 and the second grabbing part 300 are movably connected to the base 100. In the present solution, the first grabbing part 200 and the second grabbing part 300 can move relative to the base 100 simultaneously, and then switch from the first relative position to the second relative position. Therefore, the present solution can effectively improve the switching efficiency of the relative positions of the first grabbing part 200 and the second grabbing part 300, and can expand the relative movement range of the two.

[0065] With reference to Figure 1 and Figure 2 , the specific connection of the third grabbing part 400 and the base 100 is introduced as follows. In some embodiments, the third grabbing part 400 and the second grabbing part 300 are movably connected to the base 100 to realize the switching between the third relative position and the fourth relative position. In other embodiments, the third grabbing part 400 is fixedly connected to the base 100, and the second grabbing part 300 is movably connected to the base 100, i.e., the position switching is realized by the movement of the second grabbing part 300 relative to the base 100. The embodiments of the present application are described by taking the example that the second grabbing part 300 and the third grabbing part 400 are movably connected to the base 100. In the present solution, the second grabbing part 300 and the third grabbing part 400 can move relative to the base 100 simultaneously, and then switch from the third relative position to the fourth relative position. Therefore, the present solution can effectively improve the switching efficiency of the relative positions of the second grabbing part 300 and the third grabbing part 400, and can expand the relative movement range of the two.

The first sliding block 510 is connected to the second grabbing part 300, and the first sliding rail 520 is connected to the base 100. In order to describe and understand the specific movement direction of the second grabbing part 300, a third direction Z is defined, and the first sliding block 510 can slide on the first sliding rail 520 along the third direction Z. It should be noted that the third direction Z is perpendicular to the first direction X and the second direction Y, and the first direction X and the second direction Y are defined as follows. Figure 1The third direction Z can be directed upward and downward, i.e., the first slider 510 can slide on the first slide rail 520 along the third direction Z, so that the first gripping part 200 and the second gripping part 300 are switched from the first relative position to the second relative position. Further, the first slide rail 520 can be a cylinder, and the first slider 510 can be a floating block, which can slide in the cylinder along the third direction Z. In other embodiments, the second gripping part 300 is rotationally connected to the base 100, i.e., the second gripping part 300 can rotate relative to the base 100 to switch from the first relative position to the second relative position. Embodiments of the present application are described by taking the second gripping part 300 as an example which is slidingly connected to the base 100.

In some embodiments, the clamp assembly 10 includes a third slider 710 connected to the first gripping part 200 and a third slide rail 720 connected to the base 100. The third slider 710 can slide on the third slide rail 720 along the third direction Z, so that the first gripping part 200 and the second gripping part 300 are switched from the first relative position to the second relative position. In other embodiments, the first gripping part 200 is rotationally connected to the base 100, i.e., the first gripping part 200 can rotate relative to the base 100 to switch from the first relative position to the second relative position.
