At present, the commonly used flatness detection method is to use a three-coordinate measuring instrument. Due to the effective resources of the three-coordinate measuring instrument, the detection efficiency is low, which affects the production progress. CONTENT OF THE UTILITY MODEL

[0004] In view of the defects of the prior art, the purpose of the present application is to provide a battery production system and a flatness detection device, which can effectively solve the problem of low flatness detection efficiency of the cover plate of the battery box:

[0005] In a first aspect, the present application provides a battery production system, which comprises:

[0006] A battery box, the battery box is provided with a cover plate on at least one side along a first direction, the battery box is provided with a mounting portion protruding on at least one side along a second direction, the mounting portion is provided with a first mounting surface on the side facing the cover plate along the first direction;

[0007] A flatness detection device, the flatness detection device comprises a base and a detection piece, the base is arranged on the first mounting surface, the detection piece is connected with the base in a manner that it can move relative to the base along a third direction, at least part of the detection piece is arranged opposite and spaced apart from the cover plate along the first direction, the detection piece is provided with a detection surface facing the cover plate, the detection surface is arranged opposite and spaced apart from the cover plate along the first direction, the first direction and the second direction intersect, and the plane where the first direction and the second direction are located intersects the third direction.

[0008] According to the battery production system of the present application, when the flatness of the cover plate of the battery box needs to be detected, the first direction can be set as the height direction of the battery box, the second direction can be set as the width direction of the battery box, and the third direction can be set as the length direction of the battery box. By arranging the base on the first mounting surface on one side of the battery box along the second direction, and arranging at least part of the detection piece opposite and spaced apart from the cover plate along the first direction, and arranging the detection surface on one side of the detection piece along the first direction for detecting the flatness of the cover plate, by moving the detection piece along the third direction, the detection surface can detect the flatness of the cover plate along the third direction. When the detection surface does not abut against the cover plate during the movement along the third direction, it means that the flatness of the cover plate meets the assembly requirements, so that the flatness detection of the cover plate is quickly and effectively completed, and the production progress is improved.

[0009] In some embodiments of the present application, the detection member comprises a support part and at least one extending end, the support part is connected with the base in a manner capable of moving along the third direction, the support part is provided with the extending end on at least one side thereof along the second direction, and the detection surface is provided on one side of the extending end along the first direction.

[0010] By connecting the support part with the base and arranging the support part and the base on one side of the battery box along the second direction, and arranging the detection surface of the extending end opposite to the cover plate along the first direction, the detection surface can detect the flatness of the cover plate along the third direction by moving the support part along the third direction.

[0011] In some embodiments of the present application, the detection surface is arranged opposite to the base along the first direction.

[0012] Since the support part is arranged on one side of the battery box along the second direction, one end of the extending end along the second direction is connected with the support part, and the other end of the extending end along the second direction extends towards the battery box. Since the detection surface is arranged opposite to the base along the first direction, the detection surface can be arranged opposite to the cover plate along the first direction by adjusting the relative arrangement between the base and the battery box. Then, the detection surface can detect the flatness of the cover plate along the third direction by moving the detection member along the third direction.

[0013] In some embodiments of the present application, the base is provided with a second mounting surface on one side thereof along the first direction for connecting with the first mounting surface, and the other side of the base along the first direction is slidingly connected with the support part.

[0014] The second mounting surface is used for mounting and fixing the base. By arranging the second mounting surface on one side of the base along the first direction, the second mounting surface can be connected with the first mounting surface, and the support part can be slidingly connected with the other side of the base along the first direction. The spacing dimension between the detection surface and the second mounting surface along the first direction can be improved, so that the detection surface can be arranged opposite to the cover plate along the first direction.

[0015] By connecting the support part with the extending end on the side of the base along the first direction, the spacing dimension between the detection surface and the second mounting surface along the first direction can be improved, so that the detection surface can be arranged opposite to the cover plate along the first direction.

[0016] In some embodiments of the present application, the first mounting surface is provided with a hanging part on the side thereof protruding along the first direction, the second mounting surface is provided with a first avoiding slot in a recessed manner, and the hanging part is inserted into the first avoiding slot.

[0017] The battery box body can be connected with an external support through a hanging part, wherein the hanging part protrudes from the first mounting surface along the first direction, and the hanging part is inserted into the first avoiding slot, so that part of the base is attached to the first mounting surface, thereby improving the stability of the base.

[0018] In some embodiments of the present application, the hanging part is provided with a first mounting hole extending along the first direction, the base is provided with a second mounting hole corresponding to the first mounting hole, and the base and the hanging part are connected by a connecting piece inserted into the first mounting hole and the second mounting hole in sequence.

[0019] The base and the hanging part can be connected by a connecting piece, thereby fixing and connecting the flatness detection device to the battery box body, and improving the connection strength of the flatness detection device and the battery box body.

[0020] In some embodiments of the present application, the supporting part is provided with an extending end protruding from both sides along the second direction.

[0021] When the size of the extending end along the second direction is smaller than the size of the battery box body along the second direction, the flatness of the cover plate along the second direction cannot be detected during the movement of the detection surface along the third direction. By providing the extending end protruding from both sides of the supporting part along the second direction, the supporting part can be arranged on both sides of the battery box body along the second direction, and the flatness of both sides of the cover plate along the second direction can be detected by the extending ends on both sides, thereby improving the detection range of the flatness of the cover plate.

[0022] In some embodiments of the present application, the side of the extending end provided with the detection surface is further provided with a second avoiding slot, and the second avoiding slot is arranged between the detection surface and the supporting part along the second direction.

[0023] Since the supporting part is arranged on one side of the battery box body along the second direction, one end of the extending end along the second direction is connected with the supporting part, and the other end of the extending end along the second direction extends towards the direction of the battery box body. In order to reduce the interference caused by the edge of the battery box body protruding along the first direction to the cover plate and abutting against the extending end during the movement of the extending end along the third direction, the side of the extending end provided with the detection surface is further provided with a second avoiding slot, and the second avoiding slot is arranged between the detection surface and the supporting part along the second direction, thereby avoiding the protruding structure of the edge of the battery box body through the second avoiding slot, improving the smoothness during the movement of the extending end and the accuracy during the detection process.

[0024] In some embodiments of the present application, one of the base and the detection piece is provided with a sliding groove extending along the third direction, and the other of the base and the detection piece is provided with a sliding rail extending along the third direction, and the sliding groove and the sliding rail are connected in a manner that they can slide relative to each other along the third direction.

[0025] The sliding connection of the sliding groove and the sliding rail facilitates the sliding connection between the base and the detection piece in the third direction, and has simple structure and convenient operation.

[0026] In some embodiments of the present application, the first direction is configured to be consistent with the height direction of the battery box, the second direction is configured to be consistent with the width direction of the battery box, the third direction is configured to be consistent with the length direction of the battery box, the first mounting surface is perpendicular to the first direction, and the length direction of the battery box is larger than the width direction of the battery box, and the height direction of the battery box is perpendicular to the surface of the cover plate.

[0027] By arranging the base and the support part on one side of the battery box in the width direction of the battery box and moving the detection piece in the length direction of the battery box, the protruding end can only cover part of the size of the battery box in the width direction, compared with arranging the base and the support part on one side of the battery box in the length direction of the battery box and moving the detection piece in the width direction of the battery box, the protruding end needs to cover part of the size of the battery box in the length direction, which can effectively reduce the size of the protruding end in the second direction.

[0028] In a second aspect, the present application further provides a flatness detection device, which comprises:

[0029] The base is configured to be connected with the component to be detected;

[0031] According to the flatness detection device of the present application, when the flatness of the cover plate of the battery box needs to be detected, the first direction is set as the height direction of the battery box, the second direction is set as the width direction of the battery box, and the third direction is set as the length direction of the battery box. By arranging the base on one side of the battery box in the second direction, since at least part of the detection piece protrudes on one side of the base in the second direction and a detection surface for detecting the flatness of the cover plate is arranged on one side of the base in the first direction, by adjusting the relative position of the base and the cover plate, the detection surface can be arranged relative to and spaced from the cover plate in the first direction, so that by moving the detection piece in the third direction, the detection surface can detect the flatness of the cover plate in the third direction. When the detection surface does not abut against the cover plate during the movement in the third direction, it means that the flatness of the cover plate meets the assembly requirements, so that the flatness detection of the cover plate is quickly and effectively completed, and the production progress is improved.

[0032] In some embodiments of the present application, the detection member comprises a support part and at least one extending end, the support part is connected to the base in a manner capable of moving along the third direction, the support part is provided with the extending end protruding along at least one side of the second direction, and the extending end is provided with a detection surface along one side of the first direction.

[0033] By connecting the support part to the base and setting the support part and the base on one side of the battery box along the second direction, and setting the detection surface of the extending end opposite to the cover plate along the first direction, the detection surface can detect the flatness of the cover plate along the third direction by moving the support part along the third direction.

[0054] During the assembly of the battery into the vehicle, the flatness of the cover plate of the battery box body needs to be detected to meet the assembly requirements.

Due to the effective resources of the three-coordinate measuring instrument, the detection efficiency is low, which affects the production progress.

[0055] In order to solve the problem of low flatness detection efficiency of the cover plate of the battery box body, the present application provides a flatness detection device and a battery production system, which can quickly and effectively complete the flatness detection of the cover plate and improve the production progress.

[0056] The flatness detection device in the present application can not only be used for flatness detection of the cover plate of the battery box body, but also be used for appearance flatness detection of other structures. For the convenience of description, the present application only takes the flatness detection of the cover plate of the battery box body as an example for description.

[0057] The battery case may include an upper cover, a case body, and a lower cover. The upper cover and the lower cover may be respectively arranged on both sides of the case body and connected to the case body, so that the interior of the battery case forms a closed space for accommodating the battery cell assembly. Alternatively, the battery case may include an upper cover and a lower cover, wherein one of the upper cover and the lower cover forms a receiving cavity with an opening at one end, and the other of the upper cover and the lower cover is arranged at the opening of the receiving cavity and is used to seal the receiving cavity. In the embodiments of the present application, only the battery case including the upper cover, the case body, and the lower cover is used for explanation, and the flatness inspection of the upper cover is used as an example.

[0058] Combine Figures 1 to 5 As shown, the first aspect of the present application proposes a battery production system, which includes a battery box 200 and a flatness detection device 100, wherein the battery box 200 is provided with a cover plate 201 on at least one side along the first direction X, and the battery box 200 is provided with a mounting portion 203 protruding on at least one side along the second direction Y, and the mounting portion 203 is provided with a first mounting surface 2031 on the side facing the cover plate 201 along the first direction X; the flatness detection device 100 includes a base 10 and a detection member 20, the base 10 is provided on the first mounting surface 2031, the detection member 20 is connected to the base 10 in a manner that can move relative to the base 10 along a third direction Z, at least part of the detection member 20 is opposite to and spaced from the cover plate 201 along the first direction X, the detection member 20 is provided with a detection surface 221 facing the cover plate 201, the detection surface 221 is opposite to and spaced from the cover plate 201 along the first direction X, the first direction X and the second direction Y intersect, and the plane where the first direction X and the second direction Y are located intersects with the third direction Z.

[0059] Specifically, the battery production system is used to produce batteries, including the manufacture and subsequent assembly of the battery case 200. Among them, the battery case 200 needs to improve the flatness of the cover plate 201 during assembly to meet the assembly requirements. The battery case 200 includes a case body 202, and a cover plate 201 provided on at least one side of the case body 202 along the first direction Z. In order to facilitate the flatness detection device 100 to detect the flatness of the cover plate 201, the case body 202 is provided with a mounting portion 203 protruding from at least one side along the second direction Y, and the mounting portion 203 is provided with a first mounting surface 2031 on the side facing the flatness detection device 100 along the first direction Z. The flatness detection device 100 can be provided on the first mounting surface 2031, thereby being provided on one side of the battery case 200 along the second direction Y.

[0060] The flatness detection device 100 comprises a base 10 and a detection piece 20. The base 10 is used to fix and install the detection piece 20 and can be connected with the battery box 200, so as to fix and connect the flatness detection device 100 to the battery box 200, for detecting the flatness of the cover plate 201 of the battery box 200 by the detection piece 20. The base 10 can be arranged on one side of the battery box 200 along the second direction Y and connected with the first mounting surface 2031. The detection piece 20 is connected with the base 10 and can move relative to the base 10 along the third direction Z. The detection piece 20 is provided with a detection surface 221 on one side along the first direction X. The detection surface 221 can be arranged opposite and spaced apart from the cover plate 201 along the first direction X, so as to detect the flatness of the cover plate 201 by the detection surface 221 during the movement of the detection piece 20 along the third direction Z. Optionally, the detection surface 221 can be a plane and arranged substantially parallel to the surface of the cover plate 201.

[0061] In some other embodiments of the present application, the base 10 can also be arranged on one side of the battery box 200 along the first direction X and connected with the cover plate 201.

[0062] In the specific detection process, the first direction X can be set as the height direction of the battery box 200, the second direction Y can be set as the width direction of the battery box 200, and the third direction Z can be set as the length direction of the battery box 200. The length direction of the battery box 200 has a size greater than that of the width direction, and the height direction of the battery box 200 is perpendicular to the surface of the cover plate 201. Optionally, the relative movement distance of the detection piece 20 and the base 10 along the third direction Z is greater than the length of the battery box 200, so that the flatness of the cover plate 201 in the length direction can be comprehensively detected during the movement of the detection piece 20 along the third direction Z.

[0063] By arranging the base 10 on the first mounting surface 2031 of one side of the battery box 200 along the second direction Y and arranging at least part of the detection piece 20 opposite and spaced apart from the cover plate 201 along the first direction X, and arranging the detection surface 221 for detecting the flatness of the cover plate 201 on one side of the detection piece 20 along the first direction X, the detection surface 221 can detect the flatness of the cover plate 201 along the third direction Z by moving the detection piece 20 along the third direction Z. When the detection surface 221 does not abut against the cover plate 201 during the movement along the third direction Z, it means that the flatness of the cover plate 201 meets the assembly requirements, so that the flatness detection of the cover plate 201 is quickly and effectively completed, and the production progress is improved.

[0064] In combination Figures 1 to 5As shown, in some embodiments of the present application, the detection member 20 comprises a support portion 21 and at least one extending end 22, the support portion 21 is connected with the base 10 in a manner capable of moving along the third direction Z, the extending end 22 is provided on at least one side of the support portion 21 along the second direction Y, and the detection surface 221 is provided on one side of the extending end 22 along the first direction X.

[0065] Specifically, the support portion 21 is connected with the base 10 in a manner capable of moving along the third direction Z, thereby driving the extending end 22 to move along the third direction Z together. The extending end 22 is provided on at least one side of the support portion 21 along the second direction Y, including that the extending end 22 is provided on both sides of the support portion 21 along the second direction Y, or the extending end 22 is provided on only one side of the support portion 21 along the second direction Y. Wherein, the extending end 22 extends along the width direction of the battery box body 200, and can cover at least part of the cover plate 201 along the width direction of the battery box body 200, and the detection surface 221 is provided on one side of the extending end 22 along the first direction X opposite to the cover plate 201 and spaced apart, so that during the movement of the extending end 22 along the third direction Z, the flatness of the cover plate 201 within at least part of the width range is detected by the detection surface 221.

[0066] Optionally, the support portion 21 can be arranged above the base 10 along the first direction X, or the support portion 21 can be arranged on one side of the base 10 toward the battery box body 200 along the second direction Y.

[0067] Optionally, the size of the extending end 22 along the width direction of the battery box body 200 can be greater than or equal to the size of the cover plate 201, so that the entire flatness of the cover plate 201 within the width range is detected during the movement of the extending end 22 along the third direction Z. Alternatively, the size of the extending end 22 along the width direction of the battery box body 200 can be less than the size of the cover plate 201, and greater than or equal to one half of the width size of the cover plate 201, so that after detecting the flatness of part of the cover plate 201 on one side of the width direction of the battery box body 200, the base 10 and the support portion 21 can be arranged on the other side of the width direction of the battery box body 200, and the flatness of part of the cover plate 201 on the other side of the width direction of the battery box body 200 is detected by moving the extending end 22 along the third direction Z.

[0068] By connecting the support portion 21 with the base 10 and arranging the support portion 21 and the base 10 on one side of the battery box body 200 along the second direction Y, and arranging the detection surface 221 of the extending end 22 opposite to and spaced apart from the cover plate 201 along the first direction X, the flatness of the cover plate 201 along the third direction Z can be detected by the detection surface 221 through moving the support portion 21 along the third direction Z.

[0069] In combination Figures 1 to 5As shown, in some embodiments of the present application, the detection surface 221 is spaced apart from the base 10 along the first direction X.

[0070] Specifically, when testing the flatness of the cover plate 201, the height direction of the battery case 200 can be arranged along the vertical direction, so that the testing surface 221 is placed above the cover plate 201 and the flatness of the cover plate 201 can be tested and observed. The testing surface 221 can be arranged above the base 10 in the vertical direction. Since the base 10 is connected to the battery case 200, by adjusting the relative position between the base 10 and the cover plate 201 along the first direction X, the testing surface 221 is arranged opposite to and spaced from the cover plate 201 along the first direction X. Then, by moving the testing member 20 along the third direction Z, the testing surface 221 can be used to test the flatness of the cover plate 201 along the third direction Z.

[0071] Combine Figures 1 to 5 As shown, in some embodiments of the present application, the base 10 is provided with a second mounting surface 111 for connecting with the first mounting surface 2031 on one side along the first direction X, and the base 10 is slidingly connected to the support portion 21 on the other side along the first direction X.

[0072] Specifically, the base 10 is provided with a second mounting surface 111 at the bottom thereof along the first direction X, and the base 10 is connected to the first mounting surface 2031 via the second mounting surface 111. The top of the base 10 along the first direction X is connected to the support portion 21, that is, the support portion 21 is provided above the base 10 along the first direction X, thereby facilitating the provision of the extension end 22 on the support portion 21, and enabling the detection surface 221 to be opposite and spaced apart from the base 10 along the first direction X.

[0073] The second mounting surface 111 is used to mount and fix the base 10. By arranging the second mounting surface 111 on one side of the base 10 along the first direction X, the base 10 can be connected to the first mounting surface 2031 through the second mounting surface 111. At the same time, the support portion 21 is slidably connected to the other side of the base 10 along the first direction X. This can increase the spacing between the detection surface 221 and the second mounting surface 111 along the first direction X, thereby facilitating the detection surface 221 to be arranged opposite to and spaced from the cover plate 201 along the first direction X.

[0074] Combine Figures 1 to 5 As shown, in some embodiments of the present application, the support portion 21 is connected to the protruding end 22 along the first direction X at a side away from the base 10 .

[0075] Specifically, the support portion 21 is connected to the base 10 on one side along the first direction X and can move relative to the base 10 along the third direction Z. The support portion 21 is provided with an extension end 22 on the other side along the first direction X, and the extension end 22 protrudes from the support portion 21 and the base 10 along the second direction Y.

[0076] By connecting the support portion 21 to the extending end 22 away from the side of the base 10 along the first direction X, the spacing dimension between the detection surface 221 and the second mounting surface 111 along the first direction X can be increased, so that the detection surface 221 can be arranged opposite and spaced apart from the cover plate 201 along the first direction X.

[0078] Specifically, the base 10 includes a seat body 11, and the side of the seat body 11 facing the first mounting surface 2031 is provided with the first avoiding groove 112 recessed. The hanging portion 204 can be a conventional structure of the existing battery box 200, and the hanging portion 204 can be used to mount and fix the battery box 200, such as by connecting the hanging portion 204 to the vehicle body frame, so as to connect the battery box 200 to the vehicle body frame and provide power for the vehicle. In order to improve the support strength of the hanging portion 204, part of the hanging portion 204 is provided on the first mounting surface 2031 protruding along the height direction of the battery box 200, so that the surface of the first mounting surface 2031 includes part of the protruding structure. In order to facilitate the connection and fixation of the base 10 to the first mounting surface 2031, the side of the seat body 11 facing the first mounting surface 2031, i.e., the second mounting surface 111, is provided with the first avoiding groove 112 recessed, so that the surface of the second mounting surface 111 includes part of the groove structure. The hanging portion 204 is inserted into the first avoiding groove 112, so as to realize the positioning and connection of the base 10 and the hanging portion 204.

[0079] The battery box 200 can be connected to an external support member through the hanging portion 204, wherein the hanging portion 204 is provided protruding from the first mounting surface 2031 along the first direction X, and by providing the first avoiding groove 112, the hanging portion is inserted into the first avoiding groove 112, so that part of the base 10 is in close contact with the first mounting surface 2031, improving the stability of the base 10.

[0080] In combination Figures 1 to 5 As shown in some embodiments of the present application, the hanging portion 204 is provided with a first mounting hole (not shown in the figure) penetrating along the first direction X, and the base 10 is provided with a second mounting hole (not shown in the figure) corresponding to the first mounting hole, and the base 10 and the hanging portion 204 are connected by a connecting member penetrating the first mounting hole and the second mounting hole in sequence.

[0081] Specifically, the first mounting hole can be a plain hole, i.e., the inner wall of the first mounting hole is flat or curved, without a fixed structure. The second mounting hole can be a bolt hole, i.e., the inner wall of the second mounting hole includes internal threads. The connecting member can be a connecting bolt, the threaded ends of which pass through the first mounting hole and the second mounting hole in sequence and are threadedly connected to the second mounting hole. In some other embodiments of the present application, the first mounting hole and the second mounting hole can also be through holes, respectively, and the connecting member can be a connecting rod, one side of which passes through the first mounting hole and the second mounting hole and is interference fit with the second mounting hole.

[0082] The base 10 and the hanging portion 204 may be connected via a connector, thereby fixing the flatness detection device 100 to the battery case 200 and improving the connection strength between the flatness detection device 100 and the battery case 200 .

[0083] Combine Figures 1 to 5 As shown, in some embodiments of the present application, the support portion 21 is provided with protruding ends 22 on both sides along the second direction Y.

[0084] Specifically, the end of the support portion 21 facing away from the base 10 is provided with an extension end 22 on both sides along the second direction Y, so that the overall flatness detection device Z has a roughly T-shaped structure, and the extension ends 22 on both sides are respectively provided with a detection surface 221 on one side facing the base 10 along the first direction X, and the flatness of the cover plate 201 can be detected respectively through the extension ends 22 on both sides.

[0085] When the size of the protruding end 22 along the second direction Y is smaller than the size of the battery case 200 along the second direction Y, the detection surface 221 cannot detect the entire flatness of the cover plate 201 along the second direction Y during the movement of the third direction Z. By providing the support portion 21 with protruding ends 22 on both sides along the second direction Y, the support portion 21 can be sequentially arranged on both sides of the battery case 200 along the second direction Y, and the flatness of both sides of the cover plate 201 along the second direction Y can be detected respectively through the protruding ends 22 on both sides, thereby improving the detection range of the flatness of the cover plate 201.

[0086] Combine Figures 1 to 5 As shown, in some embodiments of the present application, a second avoidance groove 222 is further provided on one side of the protruding end 22 where the detection surface 221 is provided. The second avoidance groove 222 is provided along the second direction Y between the detection surface 221 and the support portion 21 .

[0087] Specifically, a second avoidance groove 222 is provided on one side of the protruding end 22 toward the cover plate 201 along the first direction X. The second avoidance groove 222 is formed by a portion of the protruding end 22 being recessed in a direction away from the cover plate 201, thereby forming a height difference with the detection surface 221 along the first direction X.

[0088] As the support part 21 is arranged at one side of the battery box body 200 along the second direction Y, one end of the extending end 22 along the second direction Y is connected with the support part 21, and the other end of the extending end 22 along the second direction Y extends towards the direction of the battery box body 200. The partial cover plate 201 and the box body 202 are connected and fixed by the fixing member, such as the bolt, wherein the fixing member is arranged to protrude the plate surface of the cover plate 201 along the first direction X. In order to reduce the interference caused by the fixing member protruding the cover plate 201 and abutting against the extending end 22 during the movement of the extending end 22 along the third direction Z, a second avoiding groove 222 is arranged at the side of the detection surface 221 of the extending end 22, and the second avoiding groove 222 is arranged between the detection surface 221 and the support part 21 along the second direction Y, and is opposite to and arranged along the first direction X of the fixing member, so as to avoid the fixing member through the second avoiding groove 222, and improve the smoothness during the movement of the extending end 22 and the accuracy during the detection process.

[0089] In combination Figures 1 to 5 As shown in some embodiments of the present application, one of the base 10 and the detection member 20 is provided with a sliding groove (not shown in the figure) extending along the third direction Z, and the other of the base 10 and the detection member 20 is provided with a sliding rail 12 extending along the third direction Z, and the sliding groove and the sliding rail 12 are connected in a manner that can slide relative to each other along the third direction Z.

[0090] Specifically, the base 10 includes a seat body 11 and a sliding rail 12 arranged at the side of the seat body 11 facing the support part 21 along the first direction X, and the support part 21 is provided with a sliding groove at the side facing the base 10 along the first direction X. By adopting the sliding connection mode of the sliding groove and the sliding rail 12, the sliding connection between the base 10 and the detection member 20 along the third direction Z is facilitated, and the structure is simple and the operation is convenient. The sliding rail 12 can be connected with the seat body 11 by the bolt, so as to be fixed on the seat body 11, and the side of the seat body 11 away from the sliding rail 12 is provided with a second mounting surface 111. The sliding groove can be formed by the bottom of the support part 21, and is connected with the sliding rail 12 in a sliding manner. Optionally, the two ends of the sliding rail 12 along the third direction Z can be provided with a stopper 13, so as to limit the movement range of the detection member 20 along the third direction Z, and reduce the phenomenon that the detection member 20 is separated from the sliding groove during the sliding process along the third direction Z.

[0091] In combination Figures 1 to 5 As shown in some embodiments of the present application, the third direction Z is configured to be consistent with the length direction of the battery box body 200, the second direction Y is configured to be consistent with the width direction of the battery box body 200, and the first direction X is configured to be consistent with the height direction of the battery box body 200, and the first mounting surface 2031 is perpendicular to the first direction X, wherein the size of the length direction of the battery box body 200 is greater than the size of the width direction, and the height direction of the battery box body 200 is perpendicular to the plate surface of the cover plate 201.

[0092] Specifically, the base 10 and the support part 21 are arranged on one side of the battery box body 200 in the width direction, the detection member 20 is movable along the length direction of the battery box body 200 and is used for detecting the flatness of the cover plate 201, and the protruding end 22 can only cover part of the size of the battery box body 200 in the width direction during the movement. Compared with arranging the base 10 and the support part 21 on one side of the battery box body 200 in the length direction of the battery box body 200 and moving the detection member 20 in the width direction of the battery box body 200, the protruding end 22 needs to cover part of the size of the battery box body 200 in the length direction, and the embodiment of the present application can effectively reduce the size of the protruding end 22 in the second direction Y, thereby reducing the space occupied by the detection member 20 and the cost.

[0093] In combination Figures 1 to 5 As shown in the second aspect, the present application further provides a flatness detection device 100, which comprises a base 10 and a detection member 20. The base 10 is configured to be connected to a component to be detected. The detection member 20 is connected to the base 10 in a manner that the detection member 20 can move relative to the base 10 in a third direction Z. At least part of the detection member 20 protrudes from one side of the base 10 in a second direction Y and is provided with a detection surface 221 on one side in a first direction X for detecting the flatness of the component to be detected. The first direction X and the second direction Y intersect, and the plane in which the first direction X and the second direction Y lie intersects the third direction Z.

[0094] Specifically, the base 10 is used for fixedly mounting the detection member 20 and can be connected to a component to be detected, such as the battery box body 200, so as to fixedly connect the flatness detection device 100 to the battery box body 200 for detecting the flatness of the cover plate 201 of the battery box body 200 by the detection member 20. The base 10 can be arranged on one side of the battery box body 200 in the second direction Y and connected to the box body 202. The detection member 20 is connected to the base 10 and can move relative to the base 10 in the third direction Z. The detection member 20 is provided with the detection surface 221 on one side in the first direction X, and the detection surface 221 can be arranged opposite to and spaced apart from the cover plate 201 in the first direction X, so that the flatness of the cover plate 201 is detected by the detection surface 221 during the movement of the detection member 20 in the first direction X. Optionally, the detection surface 221 can be a plane and arranged substantially parallel to the surface of the cover plate 201.

[0095] According to the flatness detection device 100 of the present application, when the flatness of the cover plate 201 of the battery box 200 needs to be detected, the first direction X is set as the height direction of the battery box 200, the second direction Y is set as the width direction of the battery box 200, and the third direction Z is set as the length direction of the battery box 200. By setting the base 10 on one side of the battery box 200 along the second direction Y, since at least part of the detection piece 20 is protrudingly arranged on one side of the base 10 along the second direction Y and is provided with a detection surface 221 for detecting the flatness of the cover plate 201 on one side along the first direction X, by adjusting the relative position of the base 10 and the cover plate 201, the detection surface 221 can be arranged opposite to and spaced from the cover plate 201 along the first direction X. Thus, by moving the detection piece 20 along the third direction Z, the detection surface 221 can detect the flatness of the cover plate 201 along the third direction Z. When the detection surface 221 does not abut against the cover plate 201 during the movement along the third direction Z, it means that the flatness of the cover plate 201 meets the assembly requirements. Thus, the flatness detection of the cover plate 201 is quickly and effectively completed, and the production progress is improved.

[0096] In combination Figures 1 to 5 As shown in some embodiments of the present application, the detection piece 20 includes a support part 21 and at least one protruding end 22. The support part 21 is connected to the base 10 in a manner capable of moving along the third direction Z. The support part 21 is provided with the protruding end 22 protruding on at least one side along the second direction Y. The protruding end 22 is provided with the detection surface 221 on one side along the first direction X.

[0097] By connecting the support part 21 to the base 10 and arranging the support part 21 and the base 10 on one side of the battery box 200 along the second direction Y, and by arranging the detection surface 221 of the protruding end 22 opposite to and spaced from the cover plate 201 along the first direction X, thus by moving the support part 21 along the third direction Z, the detection surface 221 can detect the flatness of the cover plate 201 along the third direction Z.
