[0026] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0027] As Figure 1 and Figure 2As shown in the figure, the battery aging device 100 of some embodiments of the present application includes a box body 110, a push-pull device 120, and a driving device 130. The box body 110 has an opening 111, and an aging area is provided inside the box body 110. The opening 111 communicates with the aging area. The push-pull device 120 includes a battery bracket 121 and a movable bracket 122. The battery bracket 121 is fixed to the movable bracket 122. The movable bracket 122 switches between a first position and a second position. When the movable bracket 122 is in the first position, the movable bracket 122 closes the opening 111, and the battery fixed to the battery bracket 121 is located inside the aging area. When the movable bracket 122 is in the second position, the battery fixed to the battery bracket 121 is located outside the aging area. The driving device 130 includes a driving mechanism 131 and a timer 132. The driving mechanism 131 is used to drive the movable bracket 122 to switch between the first position and the second position. The timer 132 is used to control the driving mechanism 131 to start after reaching a preset duration, so as to switch the movable bracket 122 from the first position to the second position.

[0028] When using the battery aging device 100 of the embodiments of the present application to age the battery, the driving mechanism 131 can drive the movable bracket 122 to switch between the first position and the second position, so as to realize the automatic entry and exit of the battery from the aging area. The timer 132 can control the driving mechanism 131 to start after reaching the preset duration, so as to move the battery to the outside of the aging area, thereby accurately controlling the aging treatment time of the battery, not only improving the work efficiency, but also obtaining higher-precision test data, and having better practicability.

[0029] An aging area is provided inside the box body 110, and the battery is aged inside the aging area. During the aging process, the movable bracket 122 is in the first position, the movable bracket 122 closes the opening 111, and the battery fixed to the battery bracket 121 is located inside the aging area.

[0030] In some embodiments of the present application, the opening 111 is located on one side of the box body 110 along the first direction X. The driving mechanism 131 includes a motor 1311 and a lead screw 1312. The axial direction of the lead screw 1312 extends along the first direction X. The lead screw 1312 is rotatably installed in the box body 110. The motor 1311 is installed in the box body 110, and the motor 1311 is used to drive the lead screw 1312 to rotate; the movable bracket 122 includes a first side plate 1221 and a second side plate 1222 that are connected to each other. The first side plate 1221 is slidably installed in the box body 110 along the first direction X. The first side plate 1221 includes a threaded hole 1224, and the lead screw 1312 is in threaded cooperation with the threaded hole 1224. The second side plate 1222 closes the opening 111.

[0031] The first direction X is the horizontal direction, that is, the movable bracket 122 switches between the first position and the second position along the horizontal direction, and the battery enters and exits the aging area along the horizontal direction; in other embodiments, the first direction X can also be other directions.

[0032] The driving mechanism 131 is used to drive the first side plate 1221 to move along the first direction X, and the second side plate 1222 is used to close the opening 111 after the battery is sent into the aging area, so as to provide a closed environment for the battery aging treatment.

[0033] The threaded hole 1224 penetrates through the first side plate 1221 along the first direction X. The first side plate 1221 is slidably installed on the box body 110 through the guide rail assembly. The motor 1311 drives the lead screw 1312 to rotate, so as to drive the first side plate 1221 to move along the first direction X, and further drive the entire movable bracket 122 to switch between the first position and the second position.

[0034] Through this setting form, the movable bracket 122 can be automatically driven to switch between the first position and the second position. The timer 132 controls the start and stop of the motor 1311, so as to accurately control the battery aging time.

[0035] In other embodiments, the driving mechanism 131 can also be other linear driving mechanisms.

[0036] In some embodiments of the present application, the timer 132 is installed on the box body 110, and the timer 132 is signal-connected to the driving mechanism 131.

[0037] The timer 132 is signal-connected to the motor 1311. The timer 132 is used to control the start of the motor 1311 after reaching the preset duration, so as to drive the first side plate 1221 to move from the first position to the second position.

[0038] Through this setting form, the timer 132 is installed on the box body 110, and the relative positions of the motor 1311 and the timer 132 are fixed, so that a reliable signal connection between the motor 1311 and the timer 132 can be achieved.

[0039] In other embodiments, the timer 132 can also be independently arranged relative to the box body 110.

[0040] As Figure 2 shown, in some embodiments of the present application, the battery aging device 100 further includes a seal 140, which is installed on the box body 110. When the movable bracket 122 is in the second position, the seal 140 abuts against the second side plate 1222 along the first direction X.

[0041] The seal 140 is made of rubber and is pasted at the edge of the opening 111 of the box body 110. When the second side plate 1222 closes the opening 111, the second side plate 1222 abuts against the seal 140, thereby improving the sealing performance at the opening 111.

[0042] Through this setting form, it is possible to improve the sealing performance of the aging area during the battery aging process, thereby precisely controlling the aging environment inside the aging area and improving the aging effect.

[0043] In other embodiments, the seal 140 can also be installed on the second side plate 1222.

[0044] Such as Figure 1 As shown, in some embodiments of the present application, the box body 110 is provided with a first positioning portion 112, and the movable bracket 122 further includes a guide plate 1223. Along the first direction X, one end of the guide plate 1223 is connected to the second side plate 1222, and the other end forms a second positioning portion 1225. When the movable bracket 122 reaches the second position, the first positioning portion 112 cooperates with the second positioning portion 1225.

[0045] As an example form, the first positioning portion 112 is a hole and groove structure, and the second positioning portion 1225 is a plug structure. The second positioning portion 1225 is inserted into the first positioning portion 112 along the first direction to achieve the cooperation between the two; as another example form, the first positioning portion 112 is a stop block structure, and the second positioning portion 1225 is the end of the guide plate 1223. The second positioning portion 1225 abuts against the first positioning portion 112 to achieve the cooperation between the two.

[0046] The first positioning portion 112 is located on one side of the box body 110 along the third direction Z, and the guide plate 1223 is connected to one side of the second side plate 1222 along the third direction Z.

[0047] Through this setting form, it is possible to fix the relative position of the movable bracket 122 and the box body 110 when the movable bracket 122 reaches the second position, thereby maintaining the movable bracket 122 at the second position and closing the battery inside the aging area during the battery aging process.

[0048] Such as Figure 2 and Figure 3 As shown, in some embodiments of the present application, the box body 110 is provided with a locking mechanism 113, including a locking driving member 1131 and a locking member 1132. The edge of the guide plate 1223 along the second direction Y forms a third positioning portion 1226. When the movable bracket 122 reaches the second position, the locking driving member 1131 drives the locking member 1132 to move along the second direction Y, so that the locking member 1132 cooperates with the third positioning portion 1226; wherein, the first direction X is perpendicular to the second direction Y.

[0049] The locking mechanism 113 is located on one side of the box body 110 along the third direction Z, that is, the locking mechanism 113 and the first positioning portion 112 are located on the same side surface of the box body 110, thereby reasonably utilizing the installation space of the box body 110.

[0050] A third positioning portion 1226 is formed by the depression of the edge of the guide plate 1223 along the second direction Y. The locking member 1132 is a positioning pin that matches the third positioning portion 1226. The locking member 1132 is snapped into the third positioning portion 1226 along the second direction Y to complete the cooperation between the two.

[0051] The first direction X and the second direction Y are two mutually perpendicular horizontal directions, and the third direction Z is the vertical direction; in other embodiments, the first direction X and the second direction Y are two other mutually perpendicular directions.

[0052] The locking mechanism 113 further includes a mounting plate. The locking driving member 1131 is mounted on the box body 110. The execution end of the locking driving member 1131 is connected to the mounting plate. The locking member 1132 is mounted on the mounting plate. The locking driving member 1131 drives the mounting plate to move along the second direction Y, thereby driving the locking member 1132 to move synchronously. The mounting plate is slidably mounted on the box body 110 along the second direction Y through a guide rail assembly, so that it can stably move along the second direction Y.

[0053] The locking driving member 1131 can be an electric push cylinder, a cylinder, etc., or other linear driving mechanisms.

[0054] Through this setting form, the guide plate 1223 can be clamped in the second direction Y, the relative position of the movable bracket 122 and the box body 110 can be fixed, and the movable bracket 122 can be maintained in the second position.

[0055] Furthermore, a plurality of third positioning portions 1226 are provided on the edge of the guide plate 1223. The plurality of third positioning portions 1226 are arranged at intervals along the first direction X. Correspondingly, a plurality of locking members 1132 are provided. The plurality of locking members 1132 are mounted on the mounting plate at intervals along the first direction X. The mounting plate drives the plurality of locking members 1132 to move synchronously to realize the cooperation between the locking members 1132 and the corresponding third positioning portions 1226.

[0056] Furthermore, along the second direction Y, third positioning portions 1226 are formed on both side edges of the guide plate 1223. Correspondingly, two locking mechanisms 113 are provided. The two locking mechanisms 113 are arranged opposite to each other along the second direction Y on both sides of the guide plate 1223. Each locking mechanism 113 cooperates with the third positioning portion 1226 on the same side.

[0057] Such as Figure 1As shown, in some embodiments of the present application, the push-pull device 120 further includes a position-in-place detection mechanism 123, which includes a position-in-place sensor 1231 and a detection member 1232. The position-in-place sensor 1231 is installed on the box body 110, and the detection member 1232 is installed on the movable bracket 122. When the movable bracket 122 reaches the second position, the position-in-place sensor 1231 detects that the detection member 1232 has moved in place and issues a closing signal, and the driving mechanism 131 is configured to respond to the closing signal and stop operating.

[0058] The position-in-place sensor 1231 is installed on the moving path of the detection member 1232. The movable bracket 122 drives the detection member 1232 to move synchronously along the first direction X. When the movable bracket 122 reaches the second position, the detection member 1232 passes by the position-in-place sensor 1231, and the position-in-place sensor 1231 detects the detection member 1232 and issues a closing signal, and the motor 1311 responds to the closing signal and stops operating.

[0059] The detection member 1232 is installed on the second side plate 1222, and the position-in-place sensor 1231 is installed at a position of the box body 110 close to the opening 111. When the second side plate 1222 closes the opening 111, the detection member 1232 moves in place.

[0060] In this way, it is possible to accurately determine that the movable bracket 122 reaches the second position, send the battery into the aging area and the second side plate 1222 closes the opening 111, and timely control the driving mechanism 131 to stop operating to maintain the movable bracket 122 at the second position.

[0061] As Figure 2 As shown, in some embodiments of the present application, the battery bracket 121 includes a rotating shaft 1211, a rotating frame 1212 and a rotation driving member 1213. The rotating shaft 1211 is installed on the movable bracket 122, the rotating frame 1212 is installed on the movable bracket 122. Along the circumference of the rotating shaft 1211, the rotating frame 1212 includes a plurality of sub-brackets 1214, and a fixture 124 is provided on each sub-bracket 1214. The rotation driving member 1213 is installed on the movable bracket 122 and is used to drive the rotation of the rotating frame 1212.

[0062] The rotating frame 1212 has a hollow through hole, the rotating shaft 1211 passes through the through hole, one end is installed on the inner side of the second side plate 1222, and the other end is suspended. The rotating frame 1212 is rotatably installed on the rotating shaft 1211, and the rotation driving member 1213 is installed on the outer side of the second side plate 1222 and is used to drive the rotation of the rotating frame 1212. Alternatively, the rotating frame 1212 is rotatably installed on the inner side of the second side plate 1222 through a bearing, and the rotating shaft 1211 only plays a supporting role.

[0063] The rotation driving member 1213 is a motor, or it can also be other rotation driving members. A plurality of sub-brackets 1214 are circumferentially arranged at intervals around the rotating shaft 1211, and each sub-bracket 1214 is provided with at least one jig 124.

[0064] With this setting form, the rotation driving member 1213 drives the rotating frame 1212 to rotate, and drives the jig 124 to rotate around the rotating shaft 1211 through the plurality of sub-brackets 1214. The jig 124 drives the battery to move, and can uniformly heat the battery during the aging process, improving the aging effect.

[0065] In other embodiments, the jig 124 can also be fixedly installed on the movable bracket 122.

[0066] In some embodiments of the present application, the axial direction of the rotating shaft 1211 extends along the first direction X, and the movable bracket 122 is slidably installed on the box body 110 along the first direction X.

[0067] That is to say, the axial direction of the rotating shaft 1211 is the same as the moving direction of the movable bracket 122.

[0068] With this setting form, the battery bracket 121 can be installed by using the second side plate 1222, and the first side plate 1221 is in threaded cooperation with the lead screw 1312 of the driving mechanism 131, reasonably utilizing the installation space of the movable bracket 122.

[0069] In other embodiments, the axial direction of the rotating shaft 1211 can also extend in other directions, and the battery bracket 121 can also be installed by using the first side plate 1221.

[0070] In some embodiments of the present application, the sub-bracket 1214 is provided with a plurality of jigs 124, and the jigs 124 are slidably installed on the sub-bracket 1214 along the axial direction of the rotating shaft 1211.

[0071] With this setting form, the number of batteries fixed by each sub-bracket 1214 can be increased, and the distance between two adjacent jigs 124 can be adjusted, which not only improves the aging efficiency but also can flexibly adapt to batteries of different specifications.

[0072] In other embodiments, the jig 124 can also be fixedly installed on the sub-bracket 1214.

[0073] Such as Figure 2 and Figure 4As shown, in some embodiments of the present application, the sub-bracket 1214 includes a notch 1215 extending along the axial direction of the rotating shaft 1211. The jig 124 includes a first part 1241, a second part 1242, and a first threaded member 1244. The first part 1241 is used to fix the battery. The first part 1241 and the second part 1242 extend into the notch 1215 from both sides. The first part 1241 and the second part 1242 are connected by the first threaded member 1244.

[0074] The length direction of the notch 1215 extends along the first direction X. The notch 1215 penetrates the sub-bracket 1214 along the circumferential direction of the rotating shaft 1211. The first part 1241 and the second part 1242 form an I-shaped structure after assembly and pass through the notch 1215. The first part 1241 and the second part 1242 are connected by the first threaded member 1244. By loosening the first threaded member 1244, the I-shaped structure can be allowed to slide in the notch 1215 along the first direction X. By tightening the first threaded member 1244, the I-shaped structure can be fixed to the sub-bracket 1214.

[0075] Specifically, the second part 1242 has a mounting hole, the first part 1241 has a counterbore hole, the first threaded member 1244 passes through the counterbore hole and is threadedly engaged with the mounting hole, and the nut of the first threaded member 1244 is engaged with the counterbore hole.

[0076] Through this setting form, the jig 124 can be simply and reliably fixed to the sub-bracket 1214, and the position of the jig 124 can be adjusted along the axial direction of the rotating shaft 1211.

[0077] It should be noted that the first part 1241 and the second part 1242 extending into the notch 1215 from both sides means that the first part 1241 and the second part 1242 are respectively arranged on both sides of the notch 1215, and the structure after their assembly passes through the notch 1215, without limiting which one of the first part 1241 and the second part 1242 specifically passes through the notch 1215.

[0078] In other embodiments, the jig 124 can also be installed on the sub-bracket 1214 by other means.

[0079] In some embodiments of the present application, the jig 124 further includes a clamping member 1243, which is rotatably mounted on the first part 1241 along the axial direction of the rotating shaft 1211.

[0080] The axial direction of the rotating shaft 1211 extends along the first direction X.

[0081] The clamping member 1243 is used to fix the battery. The clamping member 1243 is rotatably mounted on the first part 1241. During the rotation of the rotating frame 1212, the clamping member 1243 can adjust its angular position under the action of the gravity of the battery. During the aging process of the battery, due to the gravity, the battery adjusts its own position, so as to be fully heated and the aging effect is improved.

[0082] In other embodiments, the clamping member 1243 can also be fixedly mounted on the first part 1241.

[0083] Such as Figure 4 As shown, in some embodiments of the present application, the clamping member 1243 includes a rotating plate 1246, a first clamping plate 1247 and a second threaded member 1245. The rotating plate 1246 is rotatably mounted on the first part 1241 along the axial direction of the rotating shaft 1211. A pair of clamping plates 1247 are fixed on the same side of the rotating plate 1246. The second threaded member 1245 is in threaded cooperation with one of the clamping plates 1247, and the end of the second threaded member 1245 is used to abut against the battery.

[0084] The first part 1241 is provided with two mounting ears, and the two mounting ears are arranged oppositely along the first direction X. The jig 124 further includes a rotating pin. The rotating plate 1246 has a through hole. The rotating pin passes through the through hole of the rotating plate 1246 along the first direction X, and both ends of the rotating pin are respectively mounted on one mounting ear, and the rotating plate 1246 can rotate around the rotating pin.

[0085] In some embodiments of the present application, the rotating plate 1246 includes two sub - plates 1248. The through hole is arranged at the connection of the two sub - plates 1248, and the two sub - plates 1248 are located on opposite sides of the rotation axis of the rotating plate 1246. One of the sub - plates 1248 is arranged close to the first part 1241 and abuts against the first part 1241 to limit the extreme rotation position. The surface of the other sub - plate 1248 is connected to a pair of clamping plates 1247. The stacking direction of the pair of clamping plates 1247 is perpendicular to the first direction X, and the extending direction of the surface of the pair of clamping plates 1247 is perpendicular to the surface of this sub - plate 1248, so as to ensure that the battery is vertically arranged with respect to the surface of the rotating plate 1246.

[0086] As a preferred way, a pair of clamping plates 1247 are arranged at the edge of the rotating plate 1246 to increase the displacement amount of the battery during rotation.

[0087] One of the pair of clamping plates 1247 close to the rotation axis of the rotating plate 1246 is provided with a mounting hole. The second threaded member 1245 passes through the mounting hole from the outside of the pair of clamping plates 1247 and is in threaded cooperation with the mounting hole. The end of the second threaded member 1245 extends into the space between the pair of clamping plates 1247 to abut against the battery.

[0088] With this setting form, the battery can be reliably clamped, and the battery adjusts its position according to gravity, being uniformly heated during the aging process, thereby improving the aging effect.

[0089] In other embodiments, the clamping member 1243 can also be an ordinary spring clip or the like, and the clamping member 1243 can also be fixedly installed on the first part 1241.

[0090] The working process of the battery aging device 100 according to the embodiment of the present application is as follows:

[0091] Adjust the position of the jig 124 on the sub-bracket 1214, tighten the first threaded member 1244, and fix the jig 124 to the sub-bracket 1214.

[0092] Place the battery in the area between a pair of clamping plates 1247, and tighten the second threaded member 1245. The end of the second threaded member 1245 abuts against the battery, thereby reliably clamping the battery.

[0093] The driving mechanism 131 drives the movable bracket 122 to move along the first direction X from the first position to the second position. When the movable bracket 122 moves to the second position, the battery bracket 121 and the battery are located inside the aging area. The second side plate 1222 closes the opening 111. The in-place sensor 1231 detects that the detection member 1232 has moved in place, and the motor 1311 stops running. At the same time, the second positioning portion 1225 of the guide plate 1223 cooperates with the first positioning portion 112 on the box body 110.

[0094] The locking driving member 1131 of the locking mechanism 113 drives the locking member 1132 to extend along the second direction Y, and the locking member 1132 snaps into the third positioning portion 1226 of the guide plate 1223.

[0095] The aging device inside the box body 110 is started to age the battery in the aging area. The rotation driving member 1213 drives the rotating frame 1212 to rotate around the rotating shaft 1211, and the battery on the jig 124 rotates synchronously around the rotating shaft 1211 and naturally drops under its own gravity, being fully heated.

[0096] After reaching the preset time, the timer 132 finishes timing. The rotation driving member 1213 stops running, and the motor 1311 responds to the timing end signal and runs, moving the movable bracket 122 from the second position to the first position, taking the battery out of the aging area.

[0097] Since the timer 132 can control the driving mechanism 131 to start after reaching the preset duration to move the battery to the outside of the aging area, thereby precisely controlling the aging treatment time of the battery, not only improving the work efficiency, but also having higher accuracy of the test data and better practicability.

[0098] It should be noted that, without conflict, the features in the embodiments of the present application may be combined with each other.

[0099] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
