Description

Technical Field

[0001] This application relates to the field of battery testing technology, and in particular to a blade battery test fixture. Background Technology

[0002] Currently, many new energy vehicles use blade batteries as their power source. The quality of blade batteries directly affects the vehicle's range, charging speed, and safety. During the production process of blade batteries, it is necessary to use blade battery test racks to test them.

[0003] The blade battery test fixture includes a frame, a first probe fixed to the frame, a second probe slidably arranged relative to the frame, and an elbow clamping mechanism for driving the second probe to slide. The first probe abuts against an electrode at one end of the blade battery, and the second probe abuts against an electrode at the other end of the blade battery. Since the first probe is fixed and the second probe is driven by the elbow clamping mechanism, the length of the blade battery corresponding to the first and second probes in the aforementioned blade battery test fixture is also fixed.

[0004] In view of the aforementioned technologies, the inventors believe there is a need to provide a blade battery test fixture capable of testing blade batteries of different lengths and sizes. Utility Model Content

[0005] This application provides a blade battery test fixture, which can test blade batteries of different lengths and sizes.

[0006] The blade battery test fixture provided in this application adopts the following technical solution:

[0007] A blade battery test fixture includes a frame and a test device; the test device includes a support platform mounted on the frame, a first probe assembly fixed to the support platform and for abutting one end of the blade battery, a second probe assembly slidably mounted on the support platform and for abutting the other end of the blade battery, and an elbow clamp mechanism for driving the second probe assembly to slide; the support platform has a support top plate, the support top plate having an adjustment slot parallel to the sliding direction of the second probe assembly; the elbow clamp mechanism includes an elbow clamp base disposed on the top surface of the support top plate, a locking bottom plate located on the bottom surface of the support top plate, and a locking bolt connecting the elbow clamp base and the locking bottom plate and disposed in the adjustment slot.

[0008] By adopting the above technical solution, the elbow clamp mechanism can drive the second probe assembly to slide, so that the second probe assembly can adjust its position according to the length of the blade battery. When the second probe assembly slides to the appropriate position, the elbow clamp base is locked to the locking base plate by the locking bolt. The elbow clamp mechanism drives the second probe assembly to abut against the blade battery, thereby realizing the testing of blade batteries of different lengths.

[0009] Optionally, the top surface of the supporting top plate has two parallel adjustment slots; the elbow clamp base has locking pieces arranged in a one-to-one correspondence with the adjustment slots; each locking piece is provided with two locking bolts that cooperate with the locking base plate.

[0010] By adopting the above technical solution, when the elbow clamp mechanism slides on the support top plate, the cooperation of two adjusting through slots, locking bolts and locking plates makes the elbow clamp mechanism more stable during the sliding process and less prone to deflection.

[0011] Optionally, the first probe assembly includes a first bracket mounted on the supporting top plate, a first probe slidably mounted on the first bracket, a first spring sleeved on the outside of the first probe, and a first nut mounted on the front end of the first probe; one end of the first spring abuts against the first bracket and the other end abuts against the first nut, so that the first probe always tends to abut against the end of the blade battery.

[0012] By adopting the above technical solution, the specific structure of the first probe assembly is disclosed. The first spring ensures that the end of the first probe always tends to abut against the end of the blade battery, helping to guarantee that the first probe and the blade battery remain in contact during testing.

[0013] Optionally, the second probe assembly includes a second frame connected to the elbow clamp mechanism, a second probe slidably mounted on the second frame, a second spring sleeved on the outside of the second probe, and a second nut mounted on the front end of the second probe; one end of the second spring abuts against the second frame and the other end abuts against the second nut, so that the second probe always tends to abut against the end of the blade battery.

[0014] By adopting the above technical solution, the specific structure of the second probe assembly is disclosed. The second spring ensures that the end of the second probe always tends to abut against the end of the blade battery, helping to guarantee that the second probe and the blade battery remain in contact during testing.

[0015] Optionally, the first probe assembly has two first probes and the tail ends of the two first probes are connected to a first synchronization plate; the second probe assembly has two second probes and the tail ends of the two second probes are connected to a second synchronization plate.

[0016] By adopting the above technical solution, the limitation on the number of first probes in the first probe assembly and the number of second probes in the second probe assembly enables the above testing device to be applied to the testing of blade batteries with two test points at the end. Specifically, the arrangement of the first synchronization plate ensures ideal displacement synchronization of the two first probes, thereby facilitating the synchronous contact of the two first probes with the end face test points of the blade battery; similarly, the arrangement of the second synchronization plate ensures ideal displacement synchronization of the two second probes, thereby facilitating the synchronous contact of the two second probes with the end face test points of the blade battery.

[0017] Optionally, the support platform is provided with a support assembly for supporting the blade battery; the support assembly includes at least three telescopic support members; the telescopic support member includes a fixed column fixed to the support top plate and an adjusting sleeve sleeved on the outside of the fixed column; the inner side of the adjusting sleeve is symmetrically provided with sliding protrusions; the outer side of the fixed column is provided with an adjusting groove for the sliding protrusions to slide; the adjusting groove is provided with a first locking groove, a second locking groove, and a third locking groove from bottom to top for the sliding protrusions to be arranged.

[0018] By adopting the above technical solution, the support assembly can adjust the horizontal height of the blade battery to assist the first and second probe assemblies in cooperating with the blade battery, enabling the testing device to test blade batteries of different thicknesses. The support assembly includes at least three telescopic support members, the height of which can be adjusted by rotating the adjusting sleeve.

[0019] Optionally, the top of the fixing sleeve has a rubber support pad.

[0020] By adopting the above technical solution, the rubber support pad contacts the bottom of the blade battery, which helps to reduce the probability of the telescopic support component scratching the blade battery.

[0021] Optionally, the frame includes a metal frame and multiple horizontally arranged mounting partitions mounted on the metal frame; the testing device is mounted on the top surface of the mounting partitions.

[0022] By adopting the above technical solution, the specific structure of the rack is disclosed. Multiple mounting partitions for placing test devices are set on the rack, which can set up multiple sets of test devices on the rack and test multiple blade batteries in the same batch, thus helping to improve the testing efficiency of blade batteries.

[0023] Optionally, the number of test devices on the mounting partition is two, and the two test devices are arranged side by side.

[0024] Optionally, the bottom of the metal frame is fitted with four casters.

[0025] By adopting the above technical solution, four casters are installed at the bottom of the metal frame to facilitate the movement of the blade battery test rack.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. A blade battery test fixture, wherein by adjusting the elbow clamp mechanism at different positions of the adjustment slot, the second probe assembly is driven to slide to adapt to blade batteries of different lengths; after the elbow clamp mechanism is locked, the second probe assembly is driven to abut against the blade battery, thereby enabling the blade battery test fixture to test blade batteries of different lengths.

[0028] 2. By sleeved a first spring on the outside of the first probe, the end of the first probe always tends to abut against the end of the blade battery. By sleeved a second spring on the outside of the second probe, the end of the second probe always tends to abut against the end of the blade battery. This helps to ensure that the first and second probes remain in contact with both ends of the blade battery during the test.

[0029] 3. By setting a support assembly for supporting the blade battery on the support platform, the support assembly includes at least three telescopic support members, and the height of the telescopic support members can be adjusted by rotating the adjusting sleeve on the telescopic support members, so as to enable the testing of blade batteries of different thicknesses.
