Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted relay detection, in particular to a vehicle-mounted relay detection tool. Background Art

[0002] The electric vehicle battery pack is a key component for storing electrical energy in electric vehicles. It directly provides driving power for the entire vehicle. The battery pack is generally composed of multiple battery modules, each of which consists of several to more than a dozen battery cells. In addition to the battery module, the battery pack also includes outer packaging, battery management system, high and low voltage wiring harnesses, thermal management components, etc.

[0003] As the core component of new energy vehicles, the quality of the battery pack directly determines the performance of the entire vehicle. Technically, the battery pack can be divided into power battery technology, group technology and BMS technology. After the battery pack is discarded, it can be recycled and reused by disassembling the battery pack and removing the usable parts inside, including the relay.

[0004] The relays in the recycled battery pack can be recycled again after the battery is disassembled. Before recycling, the on-off performance of the relay needs to be tested. However, when testing the existing on-board battery pack relays, they can only be tested one by one using testing tools. During the test, the voltmeter needs to be in contact with the contacts of the on-board battery pack relay, and the power supply needs to be connected to the on-board battery pack relay to test whether the on-board battery pack relay is connected. Finally, it can be determined whether the on-board battery pack relay is intact. However, this detection method is inefficient and the detection effect is not intuitive enough. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 As shown, the utility model is a vehicle-mounted relay detection tool, comprising: a connecting component 1, a test component 2 and a vehicle-mounted relay 3, the connecting component 1 is evenly rotated and installed on the upper part of the test component 2, and the vehicle-mounted relay 3 is clamped on the upper surface of the test component 2;

[0027] The connecting component 1 includes an electric shock conductive block 12, a wire 13, a limiting shaft hole 14 and a connecting frame 15. The limiting shaft hole 14 is opened on the outer surface of the other end of the connecting frame 15. The electric shock conductive block 12 is symmetrically arranged at the bottom of one end of the connecting frame 15. The wire 13 is fixedly connected to the top center of the electric shock conductive block 12.

[0028] The test component 2 includes a support base 24 and a side frame 27. The side frame 27 is fixedly mounted on one side of the top of the support base 24. The upper surface of the support base 24 is evenly provided with clamping columns 22. The upper surface of the support base 24 and the edge of the clamping columns 22 are provided with an electrical connection port 212.

[0029] A conductive socket 25 is provided on one end face of the support seat 24, a light bulb 28 is evenly installed on the top surface of the side panel frame 27, a limiting rod 29 is provided on the upper side of the side panel frame 27, a limiting baffle 211 is evenly fixedly connected to the upper side of the side panel frame 27, and a tensioning spring 26 is fixedly connected to the bottom surface of the limiting baffle 211.

[0030] The connecting frame 15 in the utility model is rotatably installed on the outer surface of the limiting rod 29 through the limiting shaft hole 14, so that the connecting frame 15 can drive the electric shock conductive block 12 to flip up and down, which is convenient for installing the vehicle-mounted relay 3 that needs to be tested. The wire 13 is electrically connected to the light bulb 28 and the conductive socket 25. The connecting frame 15 is clamped with the top of the vehicle-mounted relay 3 through the electric shock conductive block 12 at one end, so that the circuit of the vehicle-mounted relay 3 can be quickly connected. The bottom end of the tensioning spring 26 is fixedly connected to the upper surface of the connecting frame 15, and can squeeze the electric shock conductive block 12 at one end of the connecting frame 15 to be tensioned and contacted with the top of the vehicle-mounted relay 3.

[0031] The utility model fixes a connecting rod 11 in the middle of one end of the connecting frame 15, which can facilitate the staff to lift the electric shock conductive block 12. The upper parts of the two ends of the side plate frame 27 are rotatably connected to the supporting rod 210, which can simultaneously lift multiple groups of electric shock conductive blocks 12. The two ends of the top of the side plate frame 27 are slidably engaged with the limit card block 21, which can limit the supporting rod 210, making it convenient for the staff to install multiple groups of vehicle-mounted relays 3 at the top detection position of the support seat 24.

[0032] The limit block 21 in the utility model is clamped with the bottom of one end of the support rod 210, the support rod 210 is movably abutted with the bottom surface of one end of the connecting rod 11, and batteries 23 are evenly arranged on the side of the support seat 24, so that when there is no direct power supply, the backup battery 23 can be used for power supply.

[0033] The working principle of the utility model is as follows: when the vehicle-mounted relay 3 is tested, it is divided into two groups of situations for testing. In the first situation, when the number to be tested is small, the connecting rods 11 can be pulled one by one to drive the connecting frame 15 to flip up and down on the outer surface of the limit rod 29, and then the vehicle-mounted relay 3 is aligned and connected with the clamping column 22 on the upper surface of the support seat 24, and then the wires of the vehicle-mounted relay 3 are symmetrically plugged into the power connection port 212, and then the external force of the connecting rod 11 is removed, so that the connecting frame 15 is flipped downward and reset under the elastic force of the tensioning spring 26, until the electric contact conductive block 12 at one end of the connecting frame 15 is aligned and connected with the contact point at the top of the vehicle-mounted relay 3, and at the same time, the power supply transmits the current to the inside of the support seat 24 through the wire, so that the light bulb 28 and the vehicle-mounted relay 3 are connected to the power supply. When the light bulb 28 lights up, it means that the vehicle-mounted relay 3 being tested can be used normally. When the corresponding light bulb 28 does not light up, it means that the vehicle-mounted relay 3 being tested cannot be used normally. In the second situation, when the number of vehicle-mounted relays 3 to be tested is large, the support rod 2 is pulled. 10 is flipped upward, so that the support rod 210 squeezes the multiple groups of connecting rods 11 to flip upward synchronously, and then the limit blocks 21 at both ends of the side plate frame 27 are pushed to slide and engage with the bottom of both ends of the support rod 210, which can limit the support rod 210, and then multiple groups of vehicle-mounted relays 3 can be installed on the upper part of the corresponding clamping column 22 at the same time, and the guide is correspondingly plugged into the inside of the power connection port 212, and then the limit block 21 is pushed in the reverse direction to separate from the two ends of the support rod 210, and the multiple groups of connecting rods 11 will be squeezed by the bulb 28 and reset and flipped downward until the multiple groups of electric contact conductive blocks 12 are synchronously engaged with the top of the vehicle-mounted relay 3, and then observe whether the corresponding bulb 28 is lit, and then the corresponding vehicle-mounted relay 3 that cannot be lit is removed, and other vehicle-mounted relays 3 are continued to be tested. Therefore, by the coordinated use of the connecting component 1 and the test component 2, the vehicle-mounted relay 3 can be quickly detected. Therefore, by using this tooling to detect the vehicle-mounted relay 3, the detection efficiency and accuracy can be improved, and the recovery efficiency of the vehicle-mounted relay 3 can be improved.

[0034] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
