New energy vehicles are mainly driven by batteries and motors to drive the vehicle to travel. Compared with traditional engine drives, battery motor drives have the advantage of saving energy. When testing new energy vehicles, the detection of battery packs is an important detection item. When testing battery packs, it is necessary to perform an extruder puncture test on the battery pack to observe the data and observe whether the battery pack is burning or exploding. The purpose is to simulate the situation when the battery pack is damaged in a car accident. The existing battery pack detection device is a horizontal detector. When in use, the battery pack is placed on the detection table, and the extrusion component and the puncture component are pushed hydraulically for testing. However, the following defects will occur in actual use: Since the extrusion realization and puncture test require the use of an extrusion head and a puncture needle respectively, after the extrusion test, the operator is required to manually replace the extrusion head with the puncture needle to continue the experiment. The operation is cumbersome and time-consuming and labor-intensive. At the same time, safety accidents are prone to occur when the operator replaces it. Utility Model Content

[0017] In order to enable the two clamping plates 4 to slide relative to or away from each other, sliding grooves are respectively provided on the placement plate 3 and the bottom shell 1, and a slider 16 that can slide in the sliding groove is provided at the lower end of the clamping plate 4. A stud 17 is rotatably connected to the front and rear axial directions in the bottom shell 1 and is threadedly connected to the two sliders 16, and the threads on the front and rear sides of the stud 17 have opposite rotation directions.

[0018] In order to rotate the stud 17 , a motor is provided at the front end of the bottom shell 1 , and the output shaft of the motor is coaxially and fixedly connected with the stud 17 .

[0019] In order to enable the push plate 6 to move left and right, the push plate 6 is slidably connected to the bottom shell 1, a hydraulic press 18 is provided in the power shell 2, and a plurality of hydraulic sleeves 19 distributed in a rectangular shape are provided at the output end of the hydraulic press 18. A hydraulic push column 20 fixed to the push plate 6 is coaxially slidably connected in the hydraulic sleeve 19.

[0020] In order to facilitate the placement of the detection instrument, a data box is provided at the left end of the bottom shell 1.

[0021] In order to facilitate the movement of the plug post 15, a stopper rod 21 is hingedly connected to the right side of the connection between the transverse groove 11 and the spiral groove 12 via a hinge shaft, and a torsion spring is arranged on the hinge shaft.

[0022] In order to facilitate support, the data box and the lower end of the power shell 2 are respectively provided with a plurality of cushion blocks.

[0023] When the utility model is in use, the motor is first started, and the motor drives the stud 17 to rotate. Since the threads on the front and rear sides of the stud 17 are in opposite directions, the two sliders 16 are driven to slide relative to each other, and the two sliders 16 drive the clamping plates 4 thereon to slide relative to each other. After the two clamping plates 4 slide relative to each other for a distance, they contact the front and rear ends of the battery pack 5 and are clamped and fixed, thereby fixing the battery pack 5 to prevent movement during the test. After the fixation is completed, the hydraulic press 18 is started at this time, and the hydraulic press 18 drives the multiple hydraulic push columns 20 to move left through the hydraulic oil, thereby driving the push plate 6 to move left, and the push plate 6 drives the rotating shaft 7 to move left in the sleeve 14. At this time, the plug column 15 is fixed, so it slides to the right in the upper side of the give way groove 13 relative to the sleeve 14. After the push plate 6 drives the fixed plate 8 and the extrusion head 9 thereon to move to the left for a distance, the extrusion head 9 contacts the battery pack 5 and squeezes the battery pack 5. At this time, it can be observed whether the battery pack 5 has combustion and explosion.

[0024] After the extrusion test is completed, the hydraulic press 18 is adjusted to make the hydraulic column slide to the right, thereby driving the push plate 6 to move to the right. After the push plate 6 moves to the right for a distance, it drives the extrusion head 9 to break contact with the battery pack 5 and continues to move to the right. At this time, the plug post 15 moves to the left in the upper clearance groove 13. When the push plate 6 moves to the right for a distance and returns to the initial position, the push plate 6 continues to move to the right. The plug post 15 slides in the upper clearance groove 13 to the upper transverse groove 11 and continues to slide to the left. The shaft 7 continues to move to the right. At this time, the plug post 15 contacts the upper stop rod 21. At this time, due to the obstruction of the stop rod 21, the plug post 15 cannot continue to slide in the upper transverse groove 11, and then slides into the upper spiral groove 12 and drives the shaft 7 to rotate 180 degrees.

[0025] The rotating shaft 7 drives the fixed plate 8 thereon to rotate 180 degrees, so that the extrusion head 9 and the puncture needle 10 are exchanged. At this time, the hydraulic press 18 is adjusted again to drive the push plate 6 to move to the left again, and the push plate 6 drives the puncture needle 10 to move to the left. After moving to the left for a distance, the puncture needle 10 contacts the battery pack 5 and punctures the battery pack 5. At the same time, the plug post 15 rotates to the lower horizontal groove 11 after rotating 180 degrees and moves to the right in the lower horizontal groove 11, moves a distance and contacts the lower baffle 21, pushes the baffle 21 away and returns to the make way groove 13. When the push plate 6 moves to the right again, the plug post 15 is inserted into the spiral groove 12 again and the puncture needle 10 is exchanged with the extrusion block again, and the battery can be squeezed again. Test.

[0026] Compared with the prior art, the utility model has the following beneficial effects: the extrusion head, puncture needle, rotating shaft, push plate, etc. are provided, which can realize the automatic conversion of the extrusion head into the puncture needle to continue the puncture test of the battery pack after the extrusion test is completed. The whole conversion process is carried out automatically, and the operator does not need to stop the machine and manually replace the puncture needle. The operation is simple and time-saving and labor-saving, which speeds up the test efficiency and ensures the personal safety of the operator. The structure is simple, the concept is novel, the use is convenient, and the practicability is strong.

[0027] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
