Description

Technical Field

[0001] This utility model relates to the technical field of battery cell testing equipment, specifically a pull-out type partition device with a hub for a high and low temperature test chamber. Background Technology

[0002] During the process of placing a single battery cell on the test cabinet, it is necessary to manually connect the current and voltage lines provided by the test cabinet to the positive and negative terminals of the battery cell. At the same time, temperature sensing wires need to be attached to the positive and negative terminals, the surface and sides of the battery cell, as well as to the shelves of the high and low temperature test chamber, to monitor the temperature of the battery cell during the test process. This is to prevent the current and voltage fluctuations or the temperature exceeding the upper and lower limits during the charging and discharging process from triggering equipment alarms due to poor contact at the connection points, which would affect the accuracy of the test data.

[0003] Currently, single-cell testing cabinets are used in conjunction with high and low temperature test chambers. These chambers have multiple layers with narrow spacing and cannot be easily moved, especially the channels near the interior, making cell loading difficult. Each channel has two current lines, two voltage lines, and four temperature sensing lines. There are no wire harness integrators on the layers. When there are two or more channels in the same layer, the wire harnesses are numerous and messy. Before each cell loading, manual sorting and confirmation of the wire harnesses is required, which is very time-consuming and prone to wire harness damage, incorrect wiring, air leakage at the high and low temperature test chamber's inlet affecting the heating / cooling rate and temperature control, and impacting the aesthetics of the site. Therefore, this paper proposes a pull-out, hub-type layered device for high and low temperature test chambers with integrated wire harnesses. Utility Model Content

[0004] The purpose of this invention is to provide a pull-out type partition device with a hub for a high and low temperature test chamber, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pull-out type partition device with a hub for a high and low temperature test chamber, comprising a cabinet and a plurality of sample shelves disposed within the cabinet, wherein the sample shelves include:

[0006] Two sliding guide rails are installed on the inner wall of the cabinet, and each sliding guide rail has a limit groove.

[0007] The skeleton is set on two sliding guide rails, and the sample insulation plate is placed on the skeleton.

[0008] A limiting pin is provided on the frame. The limiting pin and the limiting groove are slidably connected. When the sample insulation board is pulled out of the cabinet, the frame slides along the length direction of the two sliding guide rails. The movement range of the frame is limited by the cooperation of the limiting groove and the limiting pin.

[0009] By setting sliding guide rails on both sides of the frame that connect to the inner wall of the cabinet, it is easy to push and pull, and it is convenient for operators to connect wires. This effectively shortens the time for loading and unloading battery cells, thereby improving equipment utilization and reducing labor costs. At the same time, the upper limit groove design of the sliding guide rail, combined with the limit pin, can prevent the frame from hitting the inner wall protective plate of the equipment during the pushing and pulling process and effectively avoid the risk of battery cells falling.

[0010] As a further embodiment of this utility model: a wire harness limiting fixture is installed on the surface of the sample insulation plate, and multiple through holes for the wire harness to pass through are provided on the wire harness limiting fixture.

[0011] The wire harness limiting fixture and its multiple through holes allow the current, voltage, and temperature sensing wires of the test cabinet to be neatly integrated or arranged separately according to on-site testing requirements. This facilitates the pulling of the wire harness, reduces the frequency of wire searching when the tester is installing the battery cells, and avoids problems such as wire harness disorder and personnel installing the wrong wire harness on-site. In addition, it can effectively prevent air leakage at the wire inlet during the wire harness arrangement process, which would affect the lifting rate and constant temperature effect of the high and low temperature test chamber.

[0012] As a further embodiment of this utility model, the cabinet body is provided with cabinet doors.

[0013] As a further embodiment of this utility model: the side of the cabinet is provided with several inlet holes for wire harnesses to pass through.

[0014] As a further embodiment of this utility model: the number of sample holders and inlet holes are the same, and the sample holders and inlet holes correspond one-to-one.

[0015] As a further embodiment of this invention, the sample insulation plate is connected to the frame by screws, which facilitates a better connection between the sample insulation plate and the frame.

[0016] As a further embodiment of this utility model: the sliding guide rail has an L-shaped structure, and the two sliding guide rails are symmetrically arranged.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This application provides a sliding path for the frame by setting two sliding guide rails inside the cabinet, which facilitates pushing and pulling, makes it easier for operators to connect wires, and effectively shortens the time for loading and unloading battery cells, thereby improving equipment utilization and reducing labor costs. In addition, the upper limit groove and limit pin of the sliding guide rail can prevent the frame from hitting the inner wall protective plate of the equipment during the pushing and pulling process and effectively avoid the risk of battery cells falling.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 In this embodiment of the present invention, a pull-out type partition device with a hub for a high and low temperature test chamber includes a cabinet 1 and a plurality of sample shelves 2 disposed within the cabinet 1. The sample shelves 2 include:

[0028] Two sliding guide rails 21 are provided on the inner wall of the cabinet 1, and each of the two sliding guide rails 21 has a limit groove 22.

[0029] The skeleton 23 is set on two sliding guide rails 21, and the sample insulation plate 24 is placed on the skeleton 23.

[0030] A limiting pin 25 is provided on the frame 23. The limiting pin 25 and the limiting groove 22 are slidably connected. When the sample insulation board 24 is pulled out from the cabinet 1, the frame 23 slides along the length direction of the two sliding guide rails 21. The movement range of the frame 23 is limited by the cooperation of the limiting groove 22 and the limiting pin 25.

[0031] Specifically, several sample shelves 2 are evenly spaced on the inner wall of the cabinet 1. The sliding guide rails 21 are L-shaped, and two sliding guide rails 21 are symmetrically arranged. Both sliding guide rails 21 are fixedly connected to the inner wall of the cabinet 1, and the two sliding guide rails 21 are horizontally arranged to prevent the battery cells from sliding to one side when placed. The distance between the two sliding guide rails 21 is adapted to the width of the frame 23, which can support the frame 23 and limit its movement on both sides. The sample insulation plate 24 has multiple circular holes. The outer surface of the sample insulation board 24 is provided with an epoxy layer. In addition, the frame 23 is equipped with limit pins 25, the number of which is the same as the number of limit grooves 22. The ends of the limit pins 25 extend into the interior of the limit grooves 22, and the length of the limit grooves 22 is set to match the range of motion of the frame 23. When the frame 23 needs to be moved, the limit pins 25 inserted into the limit grooves 22 can cooperate with the limit grooves 22 to limit the frame 23, thereby achieving the purpose of fixing the frame 23 or adjusting the frame 23 to a suitable position.

[0032] Through the above solution, sliding guide rails 21 connected to the inner wall of cabinet 1 are set on both sides of the frame 23, which facilitates pushing and pulling, makes it easy for operators to connect wires, effectively shortens the time for battery cells to be put on and taken off the cabinet, thereby improving equipment utilization and reducing labor costs. At the same time, the design of the upper limit groove 22 of the sliding guide rail 21, combined with the limit pin 25, avoids the frame 23 from hitting the inner wall protective plate of the equipment during the pushing and pulling process and prevents the battery cells from falling off.

[0033] Please see Figure 2-6 In one embodiment, preferably, a wire harness limiting fixture 3 is installed on the surface of the sample insulation board 24. Multiple through holes 31 for the wire harness to pass through are provided on the wire harness limiting fixture 3. Further, the number of through holes 31 is multiple and not limited. In this embodiment, preferably, the number of through holes 31 is five. This allows the current wires, voltage wires, and temperature sensing wires from the test cabinet to be neatly integrated, or to be neatly arranged separately according to on-site testing requirements. This facilitates the pulling of the wire harness, reduces the frequency of wire searching when the tester installs the battery cell, and avoids problems such as wire harness misalignment and personnel installing the wrong wire harness. Furthermore, it effectively avoids air leakage at the wire inlet hole 5 during wire harness arrangement, which could affect the lifting rate and constant temperature effect of the high and low temperature test chamber.

[0034] Please see Figure 1 In one embodiment, preferably, the cabinet 1 is provided with a cabinet door 4. Furthermore, the cabinet door 4 is connected to the cabinet 1 by multiple hinges, making it convenient for staff to open the cabinet door 4 to retrieve the battery cells.

[0035] Please see Figure 1In one embodiment, preferably, the side of the cabinet 1 is provided with a plurality of inlet holes 5 for wire harnesses to pass through, so that external wire harnesses can enter the interior of the cabinet 1 through the inlet holes 5.

[0036] Please see Figure 1 In one embodiment, preferably, the number of sample holders 2 and inlet holes 5 are the same, and the sample holders 2 and inlet holes 5 correspond one-to-one.

[0037] Please see Figure 3-4 In one embodiment, preferably, the sample insulation plate 24 and the frame 23 are connected by screws. Further, the number of screws is multiple and not limited. In this embodiment, preferably, there are four screws, which are respectively located at the four corners of the sample insulation plate 24. After passing through the sample insulation plate 24, the four screws are threadedly connected to the frame 23 to facilitate the assembly and disassembly of the sample insulation plate 24 and the frame 23. The screws are made of nylon material, which can play an insulating role.
