Description

Technical Field

[0001] This invention belongs to the field of automotive testing technology, specifically a circuit testing device for new energy vehicles. Background Technology

[0002] With the increasing popularity of new energy vehicles, the complexity of their circuit systems is constantly increasing, and the difficulty of detecting circuit faults is also increasing. Existing new energy vehicle circuit testing devices mostly adopt an integrated structure with fixed interfaces, which cannot be adapted to the circuit interfaces of different vehicle models, resulting in poor versatility. At the same time, the connection between the interface module and the host of existing testing devices often lacks an effective anti-misinsertion structure and a stable snap-fit ​​structure, which easily leads to problems such as incorrect interface insertion and insecure installation. This not only affects the testing accuracy but may also damage the testing device or vehicle circuit due to misinsertion. Summary of the Invention

[0003] The purpose of this invention is to provide a circuit testing device for new energy vehicles to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a new energy vehicle circuit testing device, comprising a testing host, wherein the testing host serves as the main body of the device and is internally provided with a signal acquisition module, a data processing module and a power supply module, and its front end face is provided with at least one modular mounting slot;

[0005] A pluggable interface module is installed in the modular mounting slot and is used to connect the circuit of the vehicle under test and transmit the detection signal to the detection host.

[0006] The pluggable interface module and the modular mounting slot are provided with an anti-misinsertion positioning structure and a detachable snap-fit ​​structure;

[0007] The anti-misinsertion positioning structure includes a positioning boss disposed at the bottom of the pluggable interface module and a positioning groove formed on the inner wall of the bottom of the modular mounting slot. The positioning boss and the positioning groove are adapted in shape and correspond in position to restrict the insertion direction of the pluggable interface module.

[0008] The detachable snap-fit ​​structure includes an elastic locking component disposed on the inner side wall of the modular mounting slot and a mating groove disposed on the side of the pluggable interface module. When the pluggable interface module is fully inserted into the modular mounting slot, the elastic locking component snaps into the mating groove to achieve fixation.

[0009] As a further preferred embodiment of this technical solution: the elastic locking assembly includes a circular blind hole formed in the inner sidewall of the modular mounting slot, a compression spring disposed in the circular blind hole, and a steel ball; one end of the compression spring abuts against the bottom of the circular blind hole, and the other end abuts against the steel ball.

[0010] As a further preferred embodiment of this technical solution: the mating groove is an arc-shaped groove formed on the left and right sides of the pluggable interface module, and the curvature of the arc-shaped groove is adapted to the surface curvature of the steel ball.

[0011] As a further preferred embodiment of this technical solution: the device further includes a conductive connection component, which includes a plurality of conductive springs disposed at the bottom of the pluggable interface module and a plurality of conductive contacts disposed on the inner wall of the bottom of the modular mounting groove;

[0012] The conductive spring and the conductive contact are positioned one-to-one. When the pluggable interface module is installed in place, the conductive spring and the conductive contact are tightly attached to each other and the circuit is connected.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, a pluggable interface module design is adopted, and different vehicle models are adapted to the corresponding pluggable interface modules. By replacing the interface module, the testing of different new energy vehicle circuits can be realized without replacing the entire testing device, thereby reducing testing costs and improving the versatility of the device.

[0015] 2. In this invention, an anti-misinsertion positioning structure is set up. By cooperating with the positioning boss and the positioning groove, the insertion direction of the pluggable interface module is restricted, so as to avoid equipment damage caused by incorrect insertion direction. At the same time, in conjunction with the pin definition adaptation design of the conductive connection component, mechanical and electrical dual anti-misinsertion is achieved, which further improves the safety of detection.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figure 1 - Figure 3 As shown, the present invention provides a technical solution: a new energy vehicle circuit testing device, including a testing host 1, which serves as the main body of the device. The testing host 1 internally houses a signal acquisition module, a data processing module, and a power supply module. The signal acquisition module receives testing signals transmitted by a pluggable interface module 2. The data processing module analyzes and processes the acquired testing signals and outputs the testing results. The power supply module provides a stable power supply for the entire device. At least one modular mounting slot 101 is provided on its front end. The pluggable interface module 2 is installed in the modular mounting slot 101 and is used to connect to the circuit of the vehicle under test and transmit the testing signals to the testing host 1. The pluggable interface module 2 and the modular mounting slot 101 are provided with an anti-misinsertion positioning structure and a detachable snap-fit ​​structure. The anti-misinsertion positioning structure includes a positioning boss 3 set at the bottom of the pluggable interface module 2 and a positioning groove 4 opened on the inner wall of the bottom of the modular mounting slot 101. The positioning boss 3 and the positioning groove 4 are adapted in shape and correspond in position to limit the insertion direction of the pluggable interface module 2. The detachable snap-fit ​​structure includes an elastic locking component set on the inner side wall of the modular mounting slot 101 and a mating groove 201 set on the side of the pluggable interface module 2. When the pluggable interface module 2 is fully inserted into the modular mounting slot 101, the elastic locking component snaps into the mating groove 201 to achieve fixation.

[0022] In this embodiment, specifically: the elastic locking assembly includes a circular blind hole 501 opened in the inner sidewall of the modular mounting groove 101, a compression spring 502 disposed in the circular blind hole 501, and a steel ball 503; one end of the compression spring 502 abuts against the bottom of the circular blind hole 501, and the other end abuts against the steel ball 503.

[0023] In this embodiment, specifically: the mating groove 201 is an arc-shaped groove formed on the left and right sides of the pluggable interface module 2, and the curvature of the arc-shaped groove is adapted to the surface curvature of the steel ball 503.

[0024] In this embodiment, the specific working process of the elastic locking component is as follows: In its natural state, since the compression spring 502 is in a pre-compressed state, its elastic force acts on the steel ball 503, causing part of the spherical part of the steel ball 503 to protrude from the opening end of the circular blind hole 501. The height of the protruding part is such that it does not affect the insertion of the pluggable interface module 2 and can achieve the squeeze trigger. When the operator inserts the pluggable interface module 2 into the modular mounting slot 101, the side of the pluggable interface module 2 will first contact and squeeze the protruding steel ball 503. As the insertion force increases, the steel ball 503 is subjected to lateral pressure and squeezes the compression spring 502, causing the compression spring 502 to be further compressed. The steel ball 503 gradually retracts into the circular blind hole 501. The pluggable interface module 2 can continue to be smoothly inserted. When the pluggable interface module 2 is fully inserted into the modular mounting slot 101 and the mating groove 201 moves to the position aligned with the circular blind hole 501, the lateral pressure on the steel ball 503 disappears. The compression spring 502 pushes the steel ball 503 out under its own restoring force. The protruding part of the steel ball 503 is stuck in the mating groove 201, thereby locking the pluggable interface module 2 with the modular mounting slot 101 and ensuring that it will not fall off accidentally after installation. When disassembling, simply pull the pluggable interface module 2 outward and squeeze the steel ball 503 with the inner wall of the mating groove 201 to make the steel ball 503 retract into the circular blind hole 501, and the pluggable interface module 2 can be easily removed.

[0025] In this embodiment, specifically: the device further includes a conductive connection component, which includes a plurality of conductive springs 6 disposed at the bottom of the pluggable interface module 2 and a plurality of conductive contacts 7 disposed on the inner wall of the bottom of the modular mounting groove 101; the positions of the conductive springs 6 and the conductive contacts 7 correspond one-to-one, and when the pluggable interface module 2 is installed in place, the conductive springs 6 and the conductive contacts 7 are tightly attached to each other and the circuit is connected.

[0026] In this embodiment, specifically: the conductive connection component of this device can not only realize the transmission and power supply of detection signals, but also realize the adaptation function of different vehicle models. Specifically, the pluggable interface module 2 adapted to different vehicle models corresponds to different pin definitions, which are realized by different arrangements or functional assignments of conductive springs 6. When the pluggable interface module 2 of a non-matching vehicle model is inserted into the modular mounting slot 101, even if its mechanical structure (positioning boss 3, mating groove 201) can be adapted to the modular mounting slot 101, effective circuit conduction cannot be formed because the arrangement or functional assignment of conductive springs 6 does not match the conductive contacts 7 of the detection host 1. This further realizes the anti-misinsertion function, avoids damage to the detection host 1 or incorrect detection results due to misinsertion of the interface, and improves the practicality and safety of the device.

[0027] Example 2

[0028] Please see Figure 1 - Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the front end of the detection host 1 is provided with two modular mounting slots 101, which can simultaneously install two different pluggable interface modules 2, suitable for scenarios that require simultaneous detection of multiple electrical systems of a vehicle. The rest of the structure is exactly the same as that of embodiment 1, and will not be described again here.

[0029] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical essence of the present invention without departing from the scope of the technical solution of the present invention shall fall within the protection scope of the technical solution of the present invention.
