[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] A testing tool for a high-voltage interlock device of an automotive power battery includes a battery box body 1 and a testing port 2, as well as an outer ring fixing frame 4 and an auxiliary testing plug 3 for assisting testing personnel in testing the testing port 2;

[0027] The auxiliary detection plug 3 is slidably disposed inside the outer ring fixing frame 4. The auxiliary detection plug 3 is inserted into the detection port 2. The upper and lower sides of the auxiliary detection plug 3 are respectively provided with fixing mechanisms 5 for fixing the auxiliary detection plug 3.

[0028] The auxiliary detection plug 3 is also provided with a connecting mechanism on the side wall away from the detection port 2 for connecting and supporting the auxiliary detection plug 3.

[0029] The fixing mechanism 5 includes a rotating groove 9 and a fixing plate 11. The outer ring fixing frame 4 is bolted to the side wall of the battery box body 1 located outside the detection port 2. The rotating groove 9 is symmetrically opened inside the outer ring fixing frame 4. The fixing plate 11 is set inside the rotating groove 9. The fixing plate 11 and the auxiliary detection plug 3 are pressed against each other.

[0030] The side wall of the fixed plate 11 away from the battery box body 1 is also provided with a fastening component for rotating the fixed plate 11 to tighten the auxiliary detection plug 3.

[0031] By providing rotating grooves 9 inside the outer ring fixing frame 4, and fixing plates 11 inside the rotating grooves 9, the fixing plates 11 are driven by the fastening components to fasten and fix the auxiliary detection plug 3 inserted into the detection port 2, ensuring the stability of the auxiliary detection plug 3 inserted into the detection port 2. The detection heads 16 on the outer side wall of the auxiliary detection plug 3 are electrically connected to the positive and negative poles inside the detection port 2, so that the testing personnel can further test the detection port 2 by testing the detection heads 16 on the outer side of the auxiliary detection plug 3.

[0032] The fastening assembly includes a toothed rod 12 and a handle 13. One end of the toothed rod 12 is fixedly installed to the fixed plate 11, and the other end of the toothed rod 12 is fixedly installed to the handle 13. The toothed rod 12 passes through the outer ring fixing bracket 4 and has a threaded groove 10 corresponding to the thread on the outer arc surface of the toothed rod 12. The toothed rod 12 is threadedly connected to the threaded groove 10.

[0033] Furthermore, one end of the toothed rod 12 is fixedly installed to the fixed plate 11, and the other end of the toothed rod 12 is fixedly installed to the handle 13. The toothed rod 12 passes through the outer ring fixed frame 4 and has a threaded groove 10 corresponding to the thread on the outer arc surface of the toothed rod 12. The toothed rod 12 is threadedly connected to the threaded groove 10, and the internal thickness of the rotating groove 9 is greater than the thickness of the fixed plate 11. When the inspector rotates the handle 13, the fixed plate 11 is driven to rotate inside the rotating groove 9. Because the toothed rod 12 is threadedly connected to the threaded groove 10, the fixed plate 11 slides inside the rotating groove 9, causing the side wall of the fixed plate 11 to press against the side wall of the auxiliary detection plug 3, thereby achieving the requirement of pressing and fastening the auxiliary detection plug 3 through the fixed plate 11, ensuring the stability of the auxiliary detection plug 3 when inserted into the detection port 2.

[0034] The connecting mechanism includes connecting springs 14 and mounting plates 17. Connecting springs 14 are respectively located at the four corners of the outer side wall of the auxiliary detection plug 3. The other end of the connecting springs 14 is fixedly installed to the side wall of the mounting plate 17. The mounting plate 17 is fixedly installed to the outer ring fixing bracket 4.

[0035] The auxiliary test plug 3 has handles 15 symmetrically arranged on both sides of its outer sidewall. Two test heads 16 are arranged between the two sets of handles 15. The test heads 16 are electrically connected to the positive and negative poles inside the test port 2, respectively. The outer sidewalls of the outer ring fixing bracket 4 are respectively provided with storage frames 6 for placing the multimeter.

[0036] Connecting springs 14 are fixedly installed at the four corners of the outer side wall of the auxiliary detection plug 3. The other end of the connecting springs 14 is fixedly installed at the mounting plate 17. The mounting plate 17 is fixedly installed at the outer ring fixing frame 4. The auxiliary detection plug 3 is then connected by the connecting springs 14. Slide grooves 8 are provided between the inner walls of the two sides of the outer ring fixing frame 4. Slide blocks 7 are provided on both sides of the auxiliary detection plug 3. The slide blocks 7 are slidably installed inside the slide grooves 8. The auxiliary detection plug 3 is supported by the slide blocks 7 sliding inside the slide grooves 8. Under the elastic force of the connecting springs 14, the auxiliary detection plug 3 is originally away from the detection port 2.

[0037] When testing port 2 needs to be tested, the tester presses the auxiliary test plug 3 into the test port 2. The slider 7 of the auxiliary test plug 3 slides along the inner wall of the slide groove 8, and then the auxiliary test plug 3 is inserted into the inside of the test port 2. Then, the handle 13 is manually turned so that the fixing plate 11 presses against the side wall of the auxiliary test plug 3, thereby achieving the requirement of tightening the auxiliary test plug 3. At this time, the tester connects the connector of the multimeter to the test head 16 set on the side wall of the auxiliary test plug 3 to achieve the requirement of testing the battery box body 1.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
