Description

Technical Field

[0001] The utility model relates to the technical field of vibration test devices, in particular to a battery box vibration test device. Background Art

[0002] The battery box vibration test device refers to a device for performing vibration tests on battery boxes. The vibration test device can simulate the vibration environment that the battery box may encounter during daily use, and then test the performance of the battery box in the vibration environment to obtain effective results.

[0003] In actual work, the battery box vibration test device of the prior art can basically meet the basic vibration test requirements of the battery box, but there are still the following two problems:

[0004] 1. In actual tests, most test devices can only simulate horizontal vibration tests such as left-right vibration or front-back vibration. In actual use, the carrier of the battery box will encounter bumps and then flip over. The test device cannot simulate the performance of the battery box when it flips and vibrates at the same time under bumps;

[0005] 2. If a flip structure is used, multiple devices need to be assembled, and the devices need to be disassembled and assembled, which will increase the disassembly and assembly costs. At the same time, too many disassembly and assembly steps will reduce the overall efficiency when measuring at multiple locations.

[0006] Therefore, the utility model provides a battery box vibration test device. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and provide a battery box vibration test device.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a battery box vibration test device, comprising an outer frame and a test bench, wherein a cyclic flipping structure is arranged between the outer frame and the test bench; a mounting plate is fixedly connected to the top of the test bench, a first motor is fixedly installed on one side of the mounting plate, and a gear with missing teeth is fixedly connected to the output end of the first motor; a test groove is provided on the top of the test bench, a rectangular slide groove is provided on the inner wall of one side of the test groove, a fixed rod is fixedly connected to the inner wall of the rectangular slide groove, a sliding block is slidably connected to the outer surface of the fixed rod, a placement plate is fixedly connected to one side of the outer surface of the sliding block, and a rack plate is fixedly connected to the top of the outer surface of the placement plate near one side edge; a clamping auxiliary structure is arranged on the top of the outer surface of the placement plate; the cyclic flipping structure comprises a second motor, the second motor is fixedly connected to one side of the outer frame, a transmission rod is fixedly connected to the output end of the second motor, one end of the transmission rod is fixedly connected to a circular connecting block, the arc surface of the circular connecting block is fixedly connected to a fixed round rod, one end of the fixed round rod is slidably connected to a sliding cylinder, and one end of the sliding cylinder is fixedly connected to a sphere.

[0009] As a preferred embodiment, the outer surface of the fixed round rod is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the sliding cylinder and the circular connecting block; a rotating rod is rotatably provided on one side of the inner surface of the outer frame, one end of the rotating rod is fixedly connected to one side of the test bench, and a circular block is fixedly connected at the connection between the rotating rod and the test bench; the outer surface of the rotating rod is sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the circular block and the test bench; an auxiliary circular block is fixedly connected to the side of the test bench away from the circular block, and a stopper is fixedly connected to the top arc surface of the auxiliary circular block.

[0010] The technical effect of adopting the above further scheme is: the coordinated use of the rotating rod and the torsion spring allows the test bench to rotate along with the rotating rod, and then under the action of the fixed round rod and the sliding cylinder, in conjunction with the first spring, the test bench can rotate cyclically, thereby simulating the situation where the battery box flips over during actual testing.

[0012] The technical effect of adopting the above-mentioned further scheme is: the threaded rod can drive the screw hole block to move, and then drive the L-shaped rod and the L-shaped pressure plate to move, so that the L-shaped pressure plate can limit the top and both sides of the battery box, thereby preventing the battery box from separating from the placement plate during the test, thereby affecting the test results.

[0013] As a preferred embodiment, the inner wall of the L-shaped pressure plate is threadedly connected to a threaded auxiliary rod, the bottom end of the threaded auxiliary rod is fixedly connected to a circular pressure block, and the top of the outer surface of the L-shaped pressure plate is fixedly connected to a winding column.

During the test, they cooperate with each other, and there is no need to splice multiple equipment to cause waste of time and increase cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] 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 in 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.

[0027] like Figure 1-Figure 4 As shown, this embodiment provides a technical solution: a battery box vibration test device, comprising an outer frame 1 and a test bench 2, a cyclic flip structure 4 is arranged between the outer frame 1 and the test bench 2; a mounting plate 6 is fixedly connected to the top of the test bench 2, a first motor 7 is fixedly installed on one side of the mounting plate 6, a gear 8 with missing teeth is fixedly connected to the output end of the first motor 7, a test groove 9 is provided on the top of the test bench 2, a rectangular slide groove 10 is provided on the inner wall of one side of the test groove 9, a fixed rod 11 is fixedly connected to the inner wall of the rectangular slide groove 10, a sliding block 12 is slidably connected to the outer surface of the fixed rod 11, and the outer surface of the sliding block 12 A placement plate 3 is fixedly connected to one side of the surface, and a rack plate 13 is fixedly connected to the top of the outer surface of the placement plate 3 near one side edge; a clamping auxiliary structure 5 is arranged on the top of the outer surface of the placement plate 3; the circulating flipping structure 4 includes a second motor 41, and the second motor 41 is fixedly connected to one side of the outer frame 1, and a transmission rod 42 is fixedly connected to the output end of the second motor 41, and a circular block 43 is fixedly connected to one end of the transmission rod 42, and a fixed circular rod 45 is fixedly connected to the arc surface of the circular block 43, and one end of the fixed circular rod 45 is slidably connected to a sliding cylinder 46, and one end of the sliding cylinder 46 is fixedly connected to a sphere 47.

[0028] Further, such as Figure 2-Figure 3As shown: the outer surface of the fixed round rod 45 is sleeved with a first spring 48, and the two ends of the first spring 48 are fixedly connected to the sliding cylinder 46 and the circular block 43 respectively; a rotating rod 44 is rotatably arranged on one side of the inner surface of the outer frame 1, and one end of the rotating rod 44 is fixedly connected to one side of the test bench 2; a circular block 411 is fixedly connected to the connection between the rotating rod 44 and the test bench 2; a torsion spring 412 is sleeved on the outer surface of the rotating rod 44, and the two ends of the torsion spring 412 are fixedly connected to the circular block 411 and the test bench 2 respectively; an auxiliary circular block 49 is fixedly connected to the side of the test bench 2 away from the circular block 411, and a stopper 410 is fixedly connected to the top arc surface of the auxiliary circular block 49; the rotating rod 44 and the torsion spring 412 are used in combination, so that the test bench 2 can rotate along with the rotating rod 44, and then under the action of the fixed round rod 45 and the sliding cylinder 46, the test bench 2 can rotate cyclically in cooperation with the first spring 48, so as to simulate the situation where the battery box flips during actual testing.

[0029] The above solution also has the problem that the battery box on the placement plate 3 is generally only clamped on the left and right sides, and is easy to detach from the top when flipped. Figure 4 As shown: In the present scheme, the clamping auxiliary structure 5 includes a rectangular frame 51, the bottom of the outer surface of the rectangular frame 51 is fixedly connected to the top of the placement plate 3, and a threaded rod 52 is rotatably connected between the two sides of the inner wall of the rectangular frame 51, and the thread shapes at both ends of the threaded rod 52 are arranged symmetrically in opposite directions. The outer surface of the threaded rod 52 is symmetrically threadedly connected with two screw hole blocks 53, and the top of the outer surface of the screw hole block 53 is fixedly connected with an L-shaped rod 54, and one end of the L-shaped rod 54 is fixedly connected with an L-shaped pressure plate 55, and the threaded rod 52 can drive the screw hole block 53 to move, and then drive the L-shaped rod 54 and the L-shaped pressure plate 55 to move, so that the L-shaped pressure plate 55 can limit the top and both sides of the battery box, thereby preventing the battery box from separating from the placement plate 3 during the test, thereby affecting the test results.

[0030] The above schemes also have the problem that the cables on the battery box are relatively long and arranged in a messy way, which is easy to get tangled during the vibration test, further aggravating the mess and making it difficult to sort out. Figure 4 As shown, the inner wall of the L-shaped pressure plate 55 is threadedly connected with a threaded auxiliary rod 56, the bottom end of the threaded auxiliary rod 56 is fixedly connected with a circular pressure block 57, and the top of the outer surface of the L-shaped pressure plate 55 is fixedly connected with a winding post 58. Under the action of the circular pressure block 57 and the winding post 58, the battery box located inside the L-shaped pressure plate 55 can be further fixed, and the winding post 58 can assist in fixing components such as cables and connecting wires on the battery box.

[0031] Working principle:

[0032] like Figure 1-4 As shown:

[0033] When in use: the battery box is placed on the placement plate 3, and the threaded rod 52 is rotated so that the threaded rod 52 can drive the screw hole block 53 to move, thereby driving the L-shaped pressing plate 55 to assist in limiting the top of the battery box. At this time, the threaded auxiliary rod 56 is rotated so that the circular pressing block 57 can fix the battery box;

[0034] At this time, the first motor 7 is started so that the first motor 7 can drive the missing tooth gear 8 to rotate. When the meshing surface of the missing tooth gear 8 rotates to the rack plate 13, the placement plate 3 can be driven to move left and right, thereby generating a vibration test.

[0035] At the same time, the second motor 41 is started, so that the second motor 41 can drive the transmission rod 42 to rotate, and then drive the ball 47 to rotate, and then drive the stopper 410 and the auxiliary round block 49 to rotate, so that the test bench 2 rotates with the rotating rod 44, and then drives the torsion spring 412 to deform;

[0036] When one side of the test bench 2 contacts the bottom of the inner wall of the outer frame 1, the ball 47 squeezes the stopper 410, causing the sliding cylinder 46 to slide on the outer surface of the fixed round rod 45, thereby causing the first spring 48 to deform, thereby separating the ball 47 from the stopper 410. At this time, under the action of the torsion spring 412, the test bench 2 is reset and enters the next cycle.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
