Description

A battery vibration test transmission device Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically a battery vibration test transmission device. Background Technology

[0002] In the current booming development of the electric vehicle industry, the battery, as the core power source of electric vehicles, directly affects the performance of the entire vehicle and the safety of users' lives and property. According to the standard GB38031-2020 "Safety Requirements for Power Batteries for Electric Vehicles," vibration durability testing is an essential and crucial step before battery pack samples are assembled into electric vehicles. During the test, the battery pack sample is placed on an electromagnetic vibration table and subjected to rigorous vibration testing through inertial force loading. This simulates the complex vibration environment that the battery experiences during vehicle operation, ensuring the reliability of the battery in actual use.

[0003] However, when the battery pack malfunctions and catches fire due to internal short circuits caused by vibration, the lack of a fire isolation design for the burning battery pack fails to effectively prevent the spread of flames and high temperatures to the surrounding area. This not only poses a direct threat to the safety of test personnel but also causes the high heat generated by the combustion to continuously act on the electromagnetic vibration table itself. Furthermore, the existing device lacks a rapid removal mechanism for the burning battery pack, making it impossible to detach the burning battery pack from the electromagnetic vibration table immediately. This results in prolonged corrosion of the vibration table structure by high temperatures and flames, causing irreversible damage such as aging of the table surface materials and damage to the circuit system, severely affecting the equipment's lifespan and the accuracy of subsequent tests.

[0004] Therefore, a battery vibration test transmission device is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a battery vibration test transmission device, which has the advantages of isolating the fire of a burning battery pack and removing it quickly, thus solving the problems of existing devices being unable to effectively block the spread of fire from burning battery packs and lacking a rapid removal mechanism.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery vibration test transmission device, comprising a base, a placement platform mounted on the base, a protective cover mounted on the base, the protective cover having an open structure at both the front and rear ends, and an opening on the protective cover with a discharge mechanism for discharging a burning battery pack;

[0007] A feeding mechanism is installed on the placement platform, and the feeding mechanism is used to transport the battery pack;

[0010] In the design, the base includes a base plate, which is connected to the placement platform through a buffer device to achieve the buffering and absorption of vibration energy. The transmission component installed on the base plate has the function of driving the feeding mechanism to transport the battery pack. The base plate adopts a structural design that integrates the buffer device and the transmission component.

[0011] Preferably, the transmission assembly includes a mounting bracket, which is fixedly mounted on a base plate. A stepper motor and a gear are mounted on the mounting bracket, and the stepper motor and gear are connected in a transmission configuration.

[0012] In the design, the transmission assembly includes a mounting bracket that is fixedly mounted on the base plate to achieve structural stability support. The stepper motor and gear mounted on the mounting bracket are connected by transmission to enable precise control of the gear speed. The gear adopts a module tooth profile design that cooperates with the transmission components of the feeding mechanism.

[0013] Preferably, the discharge mechanism includes a cover, which is installed at an opening on the protective cover. A flipping frame is rotatably mounted inside the cover. The flipping frame is used to push the battery pack on the feeding mechanism. One end of the flipping frame passes through the cover and is equipped with a drive device.

[0014] In the design, the discharge mechanism includes a cover that is installed at the opening on the protective cover to achieve a protective sealing function. The flipping frame that is rotatably installed inside the cover has the ability to push the burning battery pack on the feeding mechanism. The drive device installed at one end of the flipping frame through the cover is driven by electric or pneumatic means to achieve automatic flipping operation.

[0015] Preferably, the placement platform includes a first placement plate and a second placement plate, which are fixedly connected by a limiting strip. Both the first and second placement plates are provided with sliding grooves, and a reserved groove is reserved on the opposite side of the first and second placement plates. A vibration generating device is fixedly installed at the bottom of the opposite side of the first and second placement plates.

[0016] In the design, the placement platform includes a first placement plate and a second placement plate, which are fixedly connected by a limiting strip to achieve the positioning constraint of the double plate structure. The slide grooves opened on the first and second placement plates adopt a rectangular cross-section design that matches the slide rod of the feeding mechanism and has a guiding function. The reserved grooves on the opposite side of the first and second placement plates adopt a groove structure design that matches the shape of the slide rod. The vibration generating device fixedly installed at the bottom of the opposite side of the first and second placement plates uses electromagnetic excitation to realize the load loading of the vibration test.

[0032] Example 1

[0033] As shown in Figures 1 to 6, one embodiment of the present invention is provided: a battery vibration test transmission device, including a base 1, a placement platform 3 installed on the base 1, a protective cover 2 installed on the base 1, the front and rear ends of the protective cover 2 are both designed with an open structure, the protective cover 2 has an opening and a discharge mechanism 4 is installed, the discharge mechanism 4 is used to discharge the burning battery pack.

[0036] Specifically, by setting up a protective cover 2, the open structure at both ends of the cover provides a passage for the battery pack to enter and exit.

[0038] By setting up the feeding mechanism 5, the sliding structure composed of its slide rod 51 and connecting plate 53 can quickly transport the battery pack. With the baffle 54 installed on the slide rod 51 through the inclined support plate 55, the baffle 54 can close the open position of the protective cover 2 during the battery pack transportation process, forming a second barrier to isolate the fire.

[0039] The above-mentioned structures work together to effectively block the spread of fire from the burning battery pack and achieve rapid removal of the burning battery pack through the cooperation of the discharge mechanism 4 and the feeding mechanism 5.

[0040] Example 2

[0041] In order to enable the feeding mechanism to transport the battery pack and cooperate in completing the vibration test, as shown in Figures 2, 3 and 5, in this embodiment, the base 1 includes a base plate 11, which is connected to the placement platform 3 through a buffer device 12. A transmission component 13 is installed on the base plate 11, which is used to drive the feeding mechanism 5 to transport the battery pack.

[0042] Specifically, the base 1 includes a base plate 11, which is connected to the placement platform 3 through a buffer device 12 to achieve the buffering and absorption of vibration energy. The transmission component 13 installed on the base plate 11 has the function of driving the feeding mechanism 5 to transport the battery pack.

[0043] Furthermore, the transmission assembly 13 includes a mounting bracket 132, which is fixedly mounted on the base plate 11. A stepper motor 131 and a gear 133 are mounted on the mounting bracket 132, and the stepper motor 131 and the gear 133 are driven together.

[0044] Specifically, the transmission assembly 13 includes a mounting bracket 132 that is fixedly mounted on the base plate 11 to achieve structural stability support. The stepper motor 131 and gear 133 mounted on the mounting bracket 132 are equipped with a transmission mounting system that enables precise control of the speed of the gear 133. The gear 133 adopts a module tooth profile design that cooperates with the transmission components of the feeding mechanism 5.

[0045] Furthermore, the placement platform 3 includes a first placement plate 31 and a second placement plate 32. The first placement plate 31 and the second placement plate 32 are fixedly connected by a limiting strip 33. The first placement plate 31 and the second placement plate 32 are both provided with sliding grooves 34. The first placement plate 31 and the second placement plate 32 are provided with reserved grooves 35 on opposite sides. The vibration generating device 36 is fixedly installed at the bottom of the opposite side of the first placement plate 31 and the second placement plate 32.

[0046] Specifically, the placement platform 3 includes a first placement plate 31 and a second placement plate 32, which are fixedly connected by a limiting strip 33 to achieve the positioning constraint of the double plate structure. The sliding groove 34 opened on the first placement plate 31 and the second placement plate 32 adopts a rectangular cross-section design that matches the sliding rod 51 of the feeding mechanism 5 and has a guiding function. The reserved groove 35 reserved on the opposite side of the first placement plate 31 and the second placement plate 32 adopts a groove structure design that matches the shape of the sliding rod 51. The vibration generating device 36 fixedly installed at the bottom on the opposite side of the first placement plate 31 and the second placement plate 32 uses electromagnetic excitation to realize the load loading of the vibration test.

[0047] Furthermore, there are five slide rods 51. Four slide rods 51 are slidably installed in the slide groove 34, and one slide rod 51 is slidably installed in the reserved groove 35 and has a rack 52 installed at its bottom. The rack 52 is meshed with the gear 133.

[0048] Specifically, the configuration of five slide rods 51 achieves stable support for the battery pack. Four slide rods 51 are slidably installed in the slide groove 34 with a clearance fit to provide sliding guidance. One slide rod 51 is slidably installed in the reserved groove 35 and the rack 52 installed at the bottom has a tooth profile design that matches the module of the gear 133 to provide transmission function. The meshing connection between the rack 52 and the gear 133 adopts a transmission fit structure with adjustable side clearance to achieve power transmission.

[0049] Example 3

[0050] In order to achieve the function of quickly discharging the burning battery pack, as shown in Figures 1 and 4, in this embodiment, the discharge mechanism 4 includes a cover 42, which is installed at the opening on the protective cover 2. A flipping frame 41 is rotatably installed inside the cover 42. The flipping frame 41 is used to push the battery pack on the feeding mechanism 5. One end of the flipping frame 41 passes through the cover 42 and is equipped with a driving device.

[0051] Specifically, the discharge mechanism 4 includes a cover 42 installed at the opening on the protective cover 2 to achieve a protective sealing function. The flipping frame 41, which is rotatably installed inside the cover 42, has the ability to push the burning battery pack on the feeding mechanism 5. The drive device installed at one end of the flipping frame 41 through the cover 42 is driven by electric or pneumatic means to achieve automatic flipping operation. At the same time, after the battery pack enters the protective cover 2, its position is such that it can be discharged from the protective cover 2 after the flipping frame 41 flips it. After the battery pack is flipped and pushed out, the burning battery pack can fall directly from the placement platform 3 and into the preset safety pool.

[0052] When using this invention, ensure that the base plate 11 of the base 1 is firmly fixed to the ground, and that the buffer device 12 is free from deformation damage. This ensures that the base plate 11 can effectively absorb the vibration energy transmitted from the placement platform 3 during vibration testing, preventing equipment resonance. The slide bar 51 of the feeding mechanism 5 is reset to its initial position, ensuring that the rack 52 and the gear 133 of the transmission assembly 13 maintain their initial meshing. The battery pack to be tested is placed on the slide bar 51 of the feeding mechanism 5, ensuring stability during vibration.

[0053] When the power supply of the stepper motor 131 of the transmission assembly 13 is turned on, the motor drives the gear 133 to rotate clockwise, the meshing rack 52 drives the slide rod 51 with the rack installed to slide, and through the connecting plate 53, it synchronously pulls the other four slide rods 51 to move smoothly in the slide groove 34.

[0054] When the battery pack moves to the right along the slide bar 51 into the protective cover 2, the front end of the battery pack contacts the flipping frame 41 of the discharge mechanism 4. Under the action of thrust, the flipping frame 41 rotates upward around the cover 42, forming a channel to allow the battery pack to enter the interior of the protective cover 2.

[0055] After the battery pack is fully inserted, the transmission assembly 13 stops working. At this time, the baffle 54 is tightly fitted with the front and rear openings of the protective cover 2 through the inclined support plate 55, forming a physical seal and blocking the external connection with the feeding direction of the protective cover 2.

[0056] The activated vibration generator 36 transmits a vibration load of preset frequency and amplitude to the battery pack through the first placement plate 31 and the second placement plate 32, simulating the complex vibration environment during vehicle operation. The protective cover 2 serves as a primary fire barrier, initially isolating the flames and high temperatures that may be generated by the combustion of the battery pack; the baffle 54 closes the front and rear openings, forming a secondary isolation to prevent the fire from spreading to the outside of the protective cover 2.

[0057] When a flame signal appears inside the protective cover 2, the drive device of the discharge mechanism 4 is activated, which drives the flipping frame 41 to rotate 180° on the cover 42. After the flipping frame 41 flips, one end of its push plate contacts the side of the battery pack. Under the thrust of the drive device, the burning battery pack is quickly pushed along the slide bar 51 to the opening of the protective cover 2. After the burning battery pack is separated from the slide bar 51, it falls directly into the safety pool containing the fire extinguishing medium below.

[0058] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
