[0072] At present, from the development of market situation, the application of battery is more and more extensive. The battery is not only applied to the energy storage power supply system of water power, fire power, wind power and solar power station, but also widely applied to electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of the battery, the demand of its market is also increasing.

[0073] In the battery production process, in order to make the product meet the production requirements, the battery needs to be tested, such as: the battery is tested, the voltage collection test, the temperature collection test, the pressure collection test and so on. In order to improve the test efficiency, the traditional battery test device generally includes a battery test module and a battery tray matched with the battery test module. The battery tray is used to carry the battery to be tested, and the battery is transported to the battery test module for various tests. The test connection row is constructed on the battery tray, the tray terminal is arranged on the test connection row, and the battery test module is provided with the test terminal. In the test process, the battery is placed on the battery tray, and the test terminal of the battery is electrically connected with the tray terminal. In this way, when the battery is electrically connected with the battery test module, only the tray terminal on the test connection row is matched with the test terminal on the battery test module, and the electrical connection between the battery and the test module can be realized.

[0074] When the tray terminal is matched with the test terminal, the battery tray gradually approaches the battery test module until the tray terminal is matched with the test terminal. The moving distance of the battery tray to the battery test module is set according to the design size of the tray terminal and the test terminal. Limited by the machining precision, when the battery tray moves to the preset position, the tray terminal and the test terminal may not be fully contacted, thereby causing the problem of poor contact, resulting in unreliable connection of the battery and the battery test module; the tray terminal may also be excessively contacted with the test terminal, resulting in mutual extrusion with the test terminal, causing damage to the tray terminal and the test terminal.

[0075] To solve this problem, the application provides a battery tray, which comprises a tray body, a test connection row and a tray terminal. The tray body is used to carry the battery to be tested. The test connection row is arranged on the tray body, and the test connection row is used to be electrically connected with the battery and matched with the battery test module. The tray terminal is arranged on the test connection row. When the test connection row is matched with the battery test module, the tray terminal can adaptively adjust the distance between the battery test module and the battery test module, and abut against the battery test module. The tray terminal is fully contacted with the battery test module, thereby ensuring the reliable connection of the battery on the tray body and the battery test module, thereby ensuring the stability and accuracy of the battery test module for testing the battery. At the same time, the tray terminal and the battery test module can be prevented from being excessively extruded, thereby preventing the tray terminal and the test terminal from being damaged.

[0076] Referring to Figure 1 and Figure 2 , Figure 1 Fig. 1 shows a perspective structural schematic view of the battery tray provided in some embodiments of the application; Figure 2A top view structural schematic diagram of a battery tray provided in some embodiments of the present application is shown. The battery tray comprises a tray body 1 for carrying batteries to be tested, a test connection row 2 arranged on the tray body 1 for electrically connecting with the batteries and mating with a battery test module, and a tray terminal 3 arranged on the test connection row 2. The tray terminal 3 can adaptively adjust the spacing between the tray terminal 3 and the battery test module to abut against the battery test module.

[0077] The battery tray provided in the embodiments of the present application can adaptively adjust the spacing between the tray terminal 3 and the battery test module when the tray terminal 3 mates with the battery test module, so as to ensure that the tray terminal 3 fully contacts the battery test module, thereby ensuring that the batteries on the tray body 1 are reliably connected with the battery test module, and thus ensuring the stability and accuracy of the battery test performed by the battery test module. At the same time, the tray terminal 3 and the battery test module can be prevented from being rigidly pressed, so as to prevent the tray terminal 3 and the test terminal from being damaged.

[0078] In an embodiment, the test connection row 2 is arranged at one end of the tray body 1, and the tray terminal 3 is provided with two tray terminals 3 arranged at intervals on the test connection row 2. Two test terminals are correspondingly arranged on the battery test module. When the battery tray carrying the batteries to be tested moves towards the battery test module, the tray terminal 3 mates with the test terminal one by one.

[0079] In order to enable the tray terminal 3 to adaptively adjust the spacing between the tray terminal 3 and the battery test module, the tray terminal 3 is configured to have a freedom of movement in the mating direction of the tray terminal 3 and the battery test module.

[0080] In an embodiment, the tray terminal 3 is configured to be deformable. By configuring the tray terminal 3 to be deformable, the tray terminal 3 can have the freedom of movement when the tray terminal 3 mates with the battery test module, so as to flexibly adjust the spacing with the battery test module.

[0081] In another embodiment, the tray terminal 3 is configured to be movable in the mating direction of the tray terminal 3 and the battery test module, so as to have the freedom of movement in the mating direction of the tray terminal 3 and the battery test module.

[0082] In combination with Figure 3 and Figure 4 shown, Figure 3 A front view structural schematic diagram of a battery tray provided in some embodiments of the present application is shown; Figure 4 shown, Figure 3The sectional view at B-B. The test connection row 2 has a first side facing the battery and a second side facing away from the battery, and mounting holes 21 are formed through the first side and the second side of the test connection row 2, the tray terminals 3 are elastically mounted in the mounting holes 21, and both ends of the tray terminals 3 protrude from the first side and the second side, respectively. Specifically, one end of the tray terminal 3 protruding from the first side is electrically connected to the battery, and the other end of the tray terminal 3 protruding from the second side is used to mate with the test terminal on the battery test module. By elastically mounting the tray terminal 3 in the mounting hole 21, the tray terminal 3 has a certain degree of freedom in the mounting hole 21 along the direction of the interface of the tray terminal 3 with the battery test module, that is, the tray terminal 3 can adaptively adjust the protruding length of the end thereof mating with the test terminal, thereby realizing the self-adaptive interface of the tray terminal 3 with the test terminal.

[0083] Specifically, as shown in Figure 3 and Figure 4 , the tray terminal 3 includes a terminal body 31, a first limiting portion 32, and a second limiting portion 33, the terminal body 31 is movably arranged in the mounting hole 21; the first limiting portion 32 is arranged at one end of the terminal body 31 close to the battery; the second limiting portion 33 is arranged at the other end of the terminal body 31 away from the battery; wherein the outer diameter of at least one of the first limiting portion 32 and the second limiting portion 33 is greater than the hole diameter of the mounting hole 21. By arranging the first limiting portion 32 and the second limiting portion 33 at both ends of the terminal body 31, respectively, and arranging the outer diameter of at least one of the first limiting portion 32 and the second limiting portion 33 to be greater than the hole diameter of the mounting hole 21, when the terminal body 31 moves in the mounting hole 21, the terminal body 31 is limited by the first limiting portion 32 and / or the second limiting portion 33, preventing the terminal body 31 from disengaging from the mounting hole 21.

[0084] In an embodiment, the outer diameter of the first limiting portion 32 is greater than the hole diameter of the mounting hole 21, and the outer diameter of the second limiting portion 33 is less than or equal to the hole diameter of the mounting hole 21. When the tray terminal 3 moves away from the battery, the first limiting portion 32 will abut against the test connection row 2 to prevent the tray terminal 3 from moving excessively and disengaging from the mounting hole 21. At this time, the second limiting portion 33 protrudes out of the mounting hole 21. When the tray terminal 3 interfaces with the battery test module, the second limiting portion 33 gradually contacts the battery test module and retracts into the mounting hole 21 under the extrusion of the battery test module until the second limiting portion 33 fully contacts the battery test module.

[0085] To facilitate the installation of the tray terminal 3 in the mounting hole 21, the first limiting part 32 and / or the second limiting part 33 can be detachably connected to the terminal body 31. For example, the first limiting part 32 and / or the second limiting part 33 are connected to the terminal body 31 by bolts. During assembly, the first limiting part 32 or the second limiting part 33 is first detached, the terminal body 31 is inserted into the mounting hole 21, and then the first limiting part 32 or the second limiting part 33 is assembled on the terminal body 31.

[0086] In an embodiment, please refer to Figure 4 The battery tray further comprises a reset member 4 arranged between the test connection row 2 and the tray terminal 3 and configured to drive the tray terminal 3 to move away from the battery. When the tray terminal 3 is not matched with the battery test module, the tray terminal 3 is driven by the reset member 4 to move away from the battery, so as to reset the tray terminal 3 and prepare for the next matching with the battery test module.

[0087] Specifically, the reset member 4 is sleeved outside the terminal body 31, a boss 211 is arranged in the mounting hole 21, and the two ends of the reset member 4 abut against the first limiting part 32 and the boss 211 respectively, or the two ends of the reset member 4 abut against the second limiting part 33 and the boss 211 respectively. The reset member 4 can be a spring or other elastic member. By arranging the boss 211 in the mounting hole, the reset member 4 is provided with an abutting force, so that the reset member 4 can apply a force to the first limiting part 32 or the second limiting part 33, thereby driving the tray terminal 3 to move away from the battery.

[0088] In an embodiment, the boss 211 is arranged at one end of the mounting hole 21 close to the battery, the first limiting part 32 can abut against the boss 211, the two ends of the reset member 4 abut against the second limiting part 33 and the boss 211 respectively, and the reset member 4 can be a compression spring. In a natural state, the reset member 4 applies a repulsive force to the second limiting part 33, so as to reset the tray terminal 3 to move away from the battery.

[0089] In another embodiment, the boss 211 is arranged at one end of the mounting hole 21 away from the battery, the two ends of the reset member 4 are connected to the first limiting part 32 and the boss 211 respectively, and the reset member 4 can be a tensile spring. The reset member 4 applies a pulling force to the first limiting part 32, so as to reset the tray terminal 3 to move away from the battery.

[0090] In an embodiment, a preset gap is arranged between the terminal body 31 and the inner wall of the mounting hole 21, and / or a preset gap is arranged between the reset member 4 and the inner wall of the mounting hole 21. By arranging the gap between the terminal body 31 and the inner wall of the mounting hole 21, and / or between the reset member 4 and the inner wall of the mounting hole 21, the terminal body 31 has a certain radial freedom in the mounting hole 21, which cooperates with the axial freedom of the terminal body 31 in the mounting hole 21, so that the tray terminal 3 can swing to a certain extent, and the mating end face of the tray terminal 3 and the mating end face of the test terminal can reach a parallel state, thereby ensuring that the tray terminal 3 and the test terminal are in full contact.

[0091] In an embodiment, referring back to Figure 1 , the battery tray includes at least two spaced-apart tray terminals 3, and a foolproof member is arranged between adjacent tray terminals 3. The foolproof member is arranged on the test connection row 2, and the height of the foolproof member protruding from the test connection row 2 is greater than the height of the tray terminal 3 protruding from the test connection row 2. By arranging the foolproof member protruding from the test connection row 2, a partition is formed between the two tray terminals 3, preventing the conductors in the external environment from being mistakenly connected to the two tray terminals 3 and causing a short circuit.

[0092] In an embodiment, the battery tray further includes a terminal circuit board 5, which is used to electrically connect the battery and the battery test module. The terminal circuit board 5 is arranged on the second side of the test connection row 2 and located between adjacent two tray terminals 3. The height of the terminal circuit board 5 protruding from the test connection row 2 is greater than the height of the tray terminal 3 protruding from the test connection row 2. By arranging the height of the terminal circuit board 5 protruding from the test connection row 2 to be greater than the height of the tray terminal 3 protruding from the test connection row 2, the terminal circuit board 5 plays the role of a foolproof member between the two tray terminals 3.

[0093] In an embodiment, the foolproof member includes two foolproof blocks 6, which are arranged on the two ends of the terminal circuit board 5 adjacent to the corresponding tray terminals 3. By arranging the two foolproof blocks 6, a better isolation effect can be achieved, and the foolproof blocks 6 are arranged on the two ends of the terminal circuit board 5, occupying a relatively small space, thereby allowing the terminal circuit board 5 to have a larger installation space.

[0094] In an embodiment, a plurality of collection terminals 51 are arranged on the terminal circuit board 5, and the collection terminals 51 are used to electrically connect the battery and the battery test module. An avoiding groove 61 is arranged on the side of the foolproof block 6 facing the collection terminals 51, and part of the structure of the collection terminal 51 or part of the collection terminals 51 is arranged in the avoiding groove 61. By arranging the avoiding groove 61 on the foolproof block 6, a larger setting space is provided for the collection terminals 51 without losing the partition effect.

[0095] The battery tray provided by the embodiment of the application comprises a tray body 1, a test connecting row 2, a tray terminal 3, a reset piece 4 and a foolproof piece. The tray body 1 is used for carrying a battery to be tested. The test connecting row 2 is arranged on the tray body 1 and is used for electrically connecting with the battery and being matched with a battery test module. The tray terminal 3 is elastically arranged on the test connecting row 2 through the reset piece 4. When the test connecting row 2 is matched with the battery test module, the tray terminal 3 elastically abuts against the battery test module. By elastically arranging the tray terminal 3 on the test connecting row 2, the tray terminal 3 has a certain degree of freedom. When the tray terminal 3 is matched with the battery test module, the tray terminal 3 elastically abuts against the battery test module. The tray terminal 3 can adaptively adjust the compression amount according to the spacing between the test connecting row 2 and the battery test module, so as to ensure that the tray terminal 3 is in contact with the battery test module, thereby ensuring that the battery on the tray body 1 is reliably connected with the battery test module, and thereby ensuring the stability and accuracy of the battery test performed by the battery test module. At the same time, the tray terminal 3 can be prevented from being rigidly extruded with the battery test module, thereby preventing the tray terminal 3 and the test terminal from being damaged.

[0096] At the same time, the battery tray comprises at least two tray terminals 3 arranged at intervals. The adjacent tray terminals 3 are provided with the foolproof piece. The foolproof piece is arranged on the test connecting row 2 and protrudes from the test connecting row 2 by a height greater than that by which the tray terminal 3 protrudes from the test connecting row 2. By arranging the foolproof piece protruding from the test connecting row 2 higher than the tray terminal 3, a partition is formed between the two tray terminals 3, so as to prevent a conductor in an external environment from being mistakenly connected to the two tray terminals 3 and causing a short circuit.

[0097] The embodiment of the application also provides a battery test device comprising the battery test module and the battery tray in the above embodiment. The battery tray is used for conveying a battery to be tested to the battery test module. The battery test module is configured to test the battery. By using the battery tray in the above embodiment, the tray terminal 3 can be ensured to be in full contact with the battery test module, thereby ensuring that the battery on the tray body 1 is reliably connected with the battery test module, and thereby ensuring the stability and accuracy of the battery test performed by the battery test module.

[0098] In an embodiment, the battery test module comprises a test host and a test terminal. The test terminal is elastically arranged on the test host. When the battery tray is matched with the battery test module, the test terminal elastically abuts against the tray terminal 3. By elastically arranging the test terminal on the test host, the test terminal can adaptively adjust the position when being extruded by the tray terminal 3, so as to ensure that the test terminal is in full contact with the tray terminal 3.

[0099] The embodiment of the application also provides a battery production system comprising the battery test device in the above embodiment.
