[0002] With growing global attention to environmental protection and the intensifying energy crisis, the new energy vehicle industry has experienced rapid growth. Electric vehicles, as the leading example of new energy vehicles, continue to expand their market share. As a core component of electric vehicles, the performance and quality of automotive power batteries are directly related to their safety, range, and service life. The quality of the power battery casing, a crucial structure protecting the battery's internal components, is crucial. During vehicle operation, the battery casing must withstand a variety of complex mechanical environments, including vibration, impact, and compression.

[0003] The existing patent publication number is: CN218271695U. The patent discloses an efficient battery shell quality detection device, which is intended to solve the technical problems that traditional battery shell quality detection devices only have a separate appearance detection platform or strength detection platform and traditional battery shell detection devices cannot clamp the battery shell when testing the battery shell strength.

[0004] This prior art has the following disadvantages:

[0005] (1) The prior art patent can only fix square automotive power battery housings. When a round housing needs to be fixed, the clamping head needs to be replaced, which is very inconvenient and time-consuming and labor-intensive.

[0006] (2) Patents in the prior art may damage internal parts of the device when inspecting the outer shell of a vehicle power battery, making it impossible to provide shock absorption. Utility Model Content

[0007] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a battery shell quality identification and detection device with a shock absorption function and capable of fixing round and square shells.

[0008] In order to solve the above problems, the technical solution of the present invention is: a quality identification and testing device for the casing of an automobile power battery, comprising a base plate, shock-absorbing springs are fixedly connected on all four sides of the upper side of the base plate, dampers are connected to the inner sides of the four shock-absorbing springs, and a testing frame is fixedly connected to the upper ends of the four shock-absorbing springs, a testing mechanism is provided on the upper side of the testing frame, and a fixing mechanism is provided on the inner side of the testing frame; the testing mechanism comprises a cylinder, which is fixedly connected to the upper side of the testing frame, a pressure plate is fixedly connected to the end of the cylinder, and a pressure sensor is connected to one side of the pressure plate.

[0009] Furthermore, the fixing mechanism includes two cylinders, a clamping plate and a slide groove. There are four slide grooves, and the four slide grooves are evenly distributed on the clamping plate. Both ends of the two cylinders are fixedly connected with connecting parts.

[0010] Furthermore, one side of the two connecting members is respectively connected with a sliding block, one side of the two sliding blocks is respectively rotatably connected with a connecting rod, and the other end of the two connecting rods is respectively rotatably connected with a rotating block.

[0011] Furthermore, a support rod is fixedly connected to the lower side of the clamping plate, the support rod is fixedly connected to the inner side of the detection frame, one side of the rotating block is connected to one end of four connecting rods, and the rotating block is rotatably connected to one side of the clamping plate.

[0012] Furthermore, an adjustment mechanism is provided on the upper side of each of the four sliding blocks.

[0013] Furthermore, the adjustment mechanism includes a connecting plate, which is fixedly connected to the upper side of the sliding block. Two springs are connected to one side of the connecting plate, and the ends of the two springs are respectively fixedly connected to clamping plates.

[0014] The advantages of this utility model compared with the existing technology are:

[0015] (1) The utility model is provided with a fixing mechanism and an adjusting mechanism. The battery shell is placed in the center of the clamping plate, and the two cylinders are started to drive the four connecting rods to rotate. The transmission rotating block rotates on the lower side of the clamping plate, and then drives the four sliders to slide in the four slide grooves respectively. The four sliders rotate inward synchronously to cooperate with the springs and the clamping plate to fix the battery shell. Since the two clamping plates are connected by a hinge chain, when it is necessary to fix the square battery shell, the two clamping plates cooperate with the springs to push one side of the square shell and cooperate with the four adjusting mechanisms to achieve the fixing effect. When it is necessary to fix the circular battery shell, the two springs cooperate with the hinge chain to support the circular battery shell at eight points, so that the shell can be fixed without replacing the clamping head.

[0016] (2) The utility model is provided with shock-absorbing springs and dampers. When the detection mechanism performs pressure detection on the battery shell, the four shock-absorbing springs and four dampers realize shock absorption of the device, thereby preventing the generated force from damaging the internal parts of the device.

[0023] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0025] like Figures 1 to 4 The figure shows a device for testing the quality of automotive power battery casings, comprising a base plate 1, with shock-absorbing springs 2 fixedly attached to the four sides of the upper side of the base plate 1. Dampers 3 are attached to the inner sides of the four shock-absorbing springs 2. A testing frame 4 is fixedly attached to the upper ends of the four shock-absorbing springs 2. A testing mechanism 5 is provided on the upper side of the testing frame 4, and a fixing mechanism 6 is provided on the inner side of the testing frame 4. When the testing mechanism 5 performs pressure testing on the battery casing, the four shock-absorbing springs 2 and four dampers 3 reduce the vibration of the device, preventing the generated force from damaging the internal components of the device.

[0026] The detection mechanism 5 includes a hydraulic cylinder 501, which is fixedly connected to the upper side of the detection frame 4. A pressure plate 502 is fixedly connected to the end of the hydraulic cylinder 501, and a pressure sensor 503 is connected to one side of the pressure plate 502. When the hydraulic cylinder 501 is activated, its end drives the pressure plate 502 downward. The pressure sensor 503 detects the pressure and transmits it to the operator. The pressure sensor 503 is conventional technology and will not be explained in detail here.

[0027] The fixing mechanism 6 includes two cylinders 601, a clamping plate 602, and a slide 603. There are four slides 603, each evenly distributed on the clamping plate 602. Connectors 604 are fixedly connected to the ends of the two cylinders 601. Sliding blocks 605 are connected to one side of the two connecting blocks 604. Connecting rods 606 are rotatably connected to one side of the two sliding blocks 605. Rotating blocks 607 are rotatably connected to the other ends of the two connecting rods 606. A support rod 608 is fixedly connected to the lower side of the clamping plate 602. The supporting rod 608 is fixedly connected to the inner side of the detection frame 4. The rotating blocks 607 are connected to one end of the four connecting rods 606. The rotating blocks 607 are rotatably connected to one side of the clamping plate 602. An adjustment mechanism 7 is provided on the upper side of each of the four sliding blocks 605. Place the battery casing in the center of the clamping plate 602, start the two cylinders 601 to drive the four connecting rods 606 to rotate, and the transmission rotating block 607 rotates on the lower side of the clamping plate 602, thereby driving the four sliding blocks 605 to slide in the four slide grooves 603 respectively. The four sliders 603 move synchronously and cooperate with the four adjustment mechanisms 7 to fix the battery casing.

[0028] The adjustment mechanism 7 includes a connecting plate 701, which is fixedly connected to the upper side of the sliding block 605. Two springs 702 are connected to one side of the connecting plate 701, and the ends of the two springs 702 are respectively fixedly connected to a clamping plate 703. The four sliding blocks 605 rotate inward synchronously to cooperate with the springs 702 and the clamping plates 703 to fix the battery shell. Since the two clamping plates 602 are connected by a hinge chain, when it is necessary to fix the square battery shell, the two clamping plates cooperate with the springs 702 to push against one side of the square shell, and cooperate with the four adjustment mechanisms 7 to achieve the fixing effect. When it is necessary to fix the circular battery shell, the two springs 702 cooperate with the hinge chain to support the circular battery shell at eight points, so that the shell can be fixed without replacing the clamping head.

[0029] Working Principle: Place the battery housing in the center of the clamping plate 602. Activate the two pneumatic cylinders 601 to rotate the four connecting rods 606. The transmission rotating block 607 rotates on the underside of the clamping plate 602, which in turn drives the four sliding blocks 605 to slide within the four slide slots 603. The four sliders 603 move synchronously, cooperating with the four adjustment mechanisms 7 to secure the battery housing. Activate the hydraulic cylinder 501 so that its end drives the pressure plate 502 downward. The pressure sensor 503 detects the pressure data and transmits it to the operator. At this time, the four shock-absorbing springs 2 and four dampers 3 achieve shock absorption for the device, preventing the generated force from damaging the internal parts of the device.

[0030] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
