Detailed Implementation

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0024] Reference Figures 1 to 3This utility model provides a battery capacity testing device, including a frame 100, a tray support frame 200, a probe assembly 300, a power module 500, and a lifting assembly 400. The probe assembly 300 is located directly above the tray support frame 200, which is used to support the battery pack. The power module 500 is integrated on the probe assembly 300 and is used to supply power to the probe assembly 300. The lifting assembly 400 is mounted on the frame 100 and is used to drive the probe assembly 300 or the tray support frame 200 to rise and fall. The probe assembly 300 is used to test the capacity of the battery pack.

[0025] Understandably, by integrating the power module 500 onto the probe assembly 300, the length of the wires can be greatly shortened, thereby reducing resistance loss and signal interference caused by long-distance transmission in traditional wiring, and improving the response speed of the test circuit, as well as the efficiency and accuracy of the test.

[0026] After the battery pack is placed on the tray support frame 200, the lifting component 400 drives the probe component 300 to descend or drives the tray support frame 200 to rise, so that the probe component 300 contacts the battery pack on the tray support frame 200. The probe component 300 can test the capacity of the battery pack, thereby realizing automatic testing of the battery pack capacity, reducing labor costs and improving work efficiency.

[0027] In some preferred embodiments, the lifting assembly 400 drives the probe assembly 300 to rise and fall.

[0028] Understandably, since the overall weight of the battery pack on the tray support frame 200 is much greater than the overall weight of the probe assembly 300 and the power module 500, the driving force required for the lifting assembly 400 to lift the tray support frame 200 and the battery pack as a whole would be very large. Therefore, by using the lifting assembly 400 to drive the probe assembly 300 and the power module 500 to lift as a whole, the driving force required by the lifting assembly 400 is smaller, thereby reducing the manufacturing cost of the equipment. At the same time, it allows for a smaller size of the lifting assembly 400, making the overall equipment more compact.

[0029] Furthermore, the probe assembly 300 includes a mounting frame 310, a positive probe module 320 and a negative probe module 330 disposed at the bottom of the mounting frame 310, a lifting assembly 400 connected to the mounting frame 310, a power module 500 disposed on the mounting frame 310, and the positive probe module 320 and the negative probe module 330 respectively connected to the positive and negative terminals of the power module 500.

[0030] It should be noted that the power module 500 has an internal voltage regulator circuit to ensure the safety and accuracy of the test.

[0031] Specifically, the positive electrode probe module 320 includes a first fixing plate 321 and a plurality of positive electrode probes 322 disposed on the first fixing plate 321. The first fixing plate 321 has a long strip structure, and the two ends of the first fixing plate 321 are connected to the mounting bracket 310. The plurality of positive electrode probes 322 are arranged sequentially at intervals along the length direction of the first fixing plate 321.

[0032] The negative electrode probe module 330 includes a second fixing plate 331 and a plurality of negative electrode probes 332 disposed on the second fixing plate 331. The second fixing plate 331 is a long strip structure, and the two ends of the second fixing plate 331 are connected to the mounting bracket 310. The plurality of negative electrode probes 332 are arranged sequentially at intervals along the length direction of the second fixing plate 331, and the plurality of negative electrode probes 332 correspond one-to-one with the plurality of positive electrode probes 322.

[0033] Understandably, by setting up several positive electrode probes 322 and negative electrode probes 332, capacity tests can be performed on multiple batteries simultaneously, thereby further improving testing efficiency.

[0034] In some preferred embodiments, the top of the tray support frame 200 is provided with several limiting plates 210. The limiting plates 210 are used to limit the battery pack around its perimeter, thereby enabling precise positioning of the battery pack and ensuring that each positive electrode probe 322 and negative electrode probe 332 can accurately contact the positive and negative electrodes of the battery pack. At the same time, it prevents the battery pack from shifting due to vibration or external force during the test.

[0035] Furthermore, the top of the limiting plate 210 is provided with an outwardly inclined guide portion 220. When the battery pack is inserted, the inclined guide portion 220 can guide the battery pack and guide it to slide into the center of the limiting area, reducing manual adjustment time and realizing rapid positioning of the battery pack.

[0036] In some preferred embodiments, the frame 100 is provided with a plurality of slide rods 450, and the mounting frame 310 is provided with a plurality of sliding sleeves 460. The slide rods 450 are vertically arranged, and the sliding sleeves 460 are sleeved on the outer periphery of the slide rods 450. When the lifting assembly 400 drives the probe assembly 300 to lift or lower, the mounting frame 310 in the probe assembly 300 drives the plurality of sliding sleeves 460 to slide along the length direction of the plurality of slide rods 450 respectively, thereby preventing the probe assembly 300 from tilting and ensuring the stability of the probe assembly 300 during lifting or lowering.

[0037] Furthermore, the lifting assembly 400 includes a motor 410, a lead screw 420, and a nut 430. The motor 410 is fixed on the frame 100, and the lead screw 420 is rotatably connected to the frame 100. The lead screw 420 is vertically arranged, and the motor 410 is used to drive the lead screw 420 to rotate. The lead screw 420 is threadedly connected to the nut 430, and the nut 430 is connected to the mounting bracket 310.

[0038] Understandably, the motor 410 drives the vertically mounted lead screw 420 to rotate, which in turn drives the nut 430, which is threaded into the lead screw 420, to move up and down. The nut 430 drives the probe assembly 300 to rise and fall as a whole. The lead screw 420 has high transmission precision, which makes it easy to adjust the pressure of the probe assembly 300 in contact with the battery pack, ensuring that the positive probe 322 and the negative probe 332 make accurate contact with the positive and negative terminals of the battery pack, thereby improving the testing accuracy.

[0039] Furthermore, the motor 410 and the lead screw 420 are connected by a worm gear module 440. The worm and the vertical axis of the worm gear module 440 are interleaved, which can realize the conversion from high-speed rotation of the motor 410 to low-speed, high-torque output of the lead screw 420. This enables precise control of the lifting and lowering displacement of the probe assembly 300 and improves transmission stability.

[0040] In some preferred embodiments, there are two lifting components 400, which are respectively arranged on both sides of the frame 100. The two lifting components 400 are symmetrically arranged along the center of the mounting frame 310. The two lifting components 400 can drive the probe component 300 to rise and fall at the same time, ensuring that the probe component 300 is subjected to uniform force on both sides and preventing the probe component 300 from tilting during the rise and fall.

[0041] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
