Description

Technical Field

[0001] The present invention relates to the technical field of battery detection experiments, and in particular to a new energy vehicle battery operation environment simulation experiment structure. Background Art

[0002] As we all know, in the production and processing of new energy vehicle batteries, it is necessary to simulate the impact of continuous operation on the battery in each link, evaluate the performance of the battery under various extreme and complex environmental conditions, including but not limited to key performance indicators such as capacity retention rate, charge and discharge efficiency, and internal resistance change, and determine the degree and regularity of the impact of environmental factors on battery performance.

[0003] When processing and producing new energy batteries, they need to be subjected to environmental simulation testing. The problems with existing technologies are: most of them simulate the effects of alternating hot and cold environments on batteries by directly heating and cooling them, but usually when the batteries are put into use, there will be a big difference from the test environment. For example, the hot and cold distribution in the simulated environment may be uneven, causing the battery to be locally heated or cooled, while the ambient temperature during normal use is usually evenly distributed in the battery environment, and the content of the test is relatively single, and it is difficult to deal with it in time when the battery is damaged by leakage or fire.

[0004] Based on the above-mentioned situation, we found that it is difficult for the existing new energy vehicle battery operation environment simulation test to avoid the above problems at the same time. Therefore, we proposed a new energy vehicle battery operation environment simulation experiment structure that can effectively simulate various environments, improve the uniformity of temperature distribution when adjusting the temperature, and at the same time, extinguish the fire in time after the battery is damaged or remove impurities such as leakage during post-processing. Summary of the invention

A first air duct is fixedly connected to the top of the transparent cover, and a second air duct is fixedly connected to the rear side of the transparent cover. A fan is arranged on the top of the first air duct, and an output pipe is fixedly connected to the output end of the fan, and a three-way valve is fixedly connected to the side of the output pipe away from the fan. The first air duct and the second air duct are fixedly connected to the three-way valve on one side thereof. A heating pipe is fixedly connected to the rear side of the inner side of the transparent cover, and the heating pipe is arranged on the front side of the second air duct. Door panels are arranged on the inner sides of both sides of the transparent cover;

[0009] The bottom frame includes a short shaft, the short shaft is rotatably connected to the inner side of the limiting frame, the outer side of the short shaft is rotatably connected to a balance frame, a transverse groove is provided on the inner side of the balance frame, a vertical rod is fixedly connected to the inner side of the limiting frame, the top and bottom of the balance frame are fixedly connected to a return spring, the return spring is arranged on the outer side of the vertical rod, and the return spring is fixedly connected to the limiting frame on a side away from the balance frame;

[0010] The placing frame includes a connecting frame, which is fixedly connected to the inner side of the balancing frame, and a bent frame is fixedly connected to the inner side of the connecting frame. The right side of the top of the bent frame is rotatably connected to a fixed frame via a hinge, and the bottom of the left side of the fixed frame is fixedly connected to a hook, and the top of the bent frame is fixedly connected to a buckle, and the buckle and the hook are clamped together. The top of the fixed frame is fixedly connected to a sleeve, and a sliding column is provided on the inner side of the sleeve, and the bottom of the sliding column is rotatably connected to a pressing frame via a rotating shaft.

[0011] The above technical scheme is adopted to form a simulated experimental space by setting a tray rack and a transparent cover. When in use, the battery is fixed in the placement rack on the inner side of the bottom frame. The cooling rack inside the transparent cover is installed with an evaporator. The compressor of the external cooling cycle system compresses the refrigerant into a high-temperature and high-pressure gas, and then dissipates heat through the condenser to become a high-pressure liquid. After the high-pressure liquid is throttled and reduced in pressure by a throttling device, it becomes a low-temperature and low-pressure liquid, which evaporates and absorbs heat in the evaporator, thereby reducing the ambient temperature. The set heating pipe is used to generate heat through a resistance wire to increase the temperature in the environment. The fan at the top of the transparent cover blows it into the output pipe and switches the connection of the three-way valve as needed. When connected with the first air duct, the airflow takes away the low temperature of the evaporator and evenly distributes it inside the transparent cover and contacts the battery. Similarly, when connected with the second air duct, the surface heat of the heating pipe will be taken away and evenly distributed. The set spray pipe is used to extract external water and spray it onto the battery surface through a nozzle. The battery is in a simulated water immersion state. When the battery burns due to unstable operation or damage, the door panel can be lowered to isolate the outside air, and water can be sprayed through the sprinkler pipe and nozzle to extinguish the fire. The residue and water will fall into the inside of the tray rack for later discharge. When the battery and the placement rack are installed, the battery is directly placed on the bent rack, and then the fixed rack is rotated along the hinge to make the battery stuck on the inside of the fixed rack. In this process, according to the different heights of batteries of different specifications, the sliding column and the bottom pressure rack will press against the top of the battery, and then the sliding column will slide along the sleeve to adapt to the size of the battery for fixing. Then, the fixed rack can be quickly fixed to the top of the bent rack through the buckle and hook to avoid loosening. When performing a shaking test, one side of the balance frame can be pressed down and pulled up vertically. At this time, the entire balance frame will repeatedly shake along the limit frame through the short axis to simulate the working condition of the battery under shaking conditions. The reset spring will deform due to compression and tension during shaking, so it will also assist the balance frame to reset during rebound.

[0012] The present invention is further configured as follows: a tension spring is fixedly connected to the inner side of the pressing frame, a drawing frame is slidably connected to the inner side of the pressing frame, and a side of the drawing frame close to the tension spring is fixedly connected to the tension spring.

[0013] By adopting the above technical solution, a tension spring is arranged to cooperate with the drawer, and when fixing a battery of larger size, the drawer can be pulled out from the inner side of the pressing frame. At this time, the tension spring is stretched, and after being stuck outside the battery, the tension spring pulls the drawer back to the inner side of the pressing frame to match the size of the battery for fixing.

[0014] The present invention is further configured as follows: a spacer is fixedly connected to the inner side of the sleeve, a sleeve is slidably connected to the inner side of the spacer, the inner side of the sleeve is filled with viscous oil, flow holes are provided at the top and bottom of the inner side of the spacer, and the bottom of the sleeve is fixedly connected to the sliding column.

[0015] By adopting the above technical solution, by setting the spacer and the sleeve, when the fixing frame fixes the battery, the sliding column is subjected to force, and the sleeve connected thereto will be displaced along the spacer and push the internal viscous oil to flow along the flow hole.

[0016] The present invention is further configured as follows: a pressure spring is fixedly connected to the top of the inner side of the sleeve, the bottom of the pressure spring is fixedly connected to the sleeve, and the bottom of the sliding column penetrates the sleeve and the fixing frame and is slidably connected to the sleeve.

[0017] By adopting the above technical solution, a pressure spring is set, which always presses the sleeve, so that the sliding column connected to it is always close to the battery. When simulating a vibration or shaking environment, if the battery is subjected to a force that may cause itself to move, the pressure frame, sliding column and sleeve in contact with it will be affected by hydraulic damping, and therefore will not be directly displaced, thereby reducing the possibility of the battery coming loose. When the fixing frame fixes the battery, it is a continuous and slow process, so the sleeve will promote the circulation of viscous oil and press the reset spring, so that it can fit batteries of different sizes normally.

[0018] The present invention is further configured as follows: the top of the transparent cover is fixedly connected to a limit frame, the inner side of the limit frame is slidably connected to a transmission block, both sides of the transmission block are fixedly connected to winding frames, and the sides of the two winding frames away from the transmission block are fixedly connected to the two door panels respectively.

[0019] By adopting the above technical solution, a limit frame is provided to cooperate with the transmission block, and the transmission block is moved vertically inside the limit frame to drive the two door panels fixed thereto to be lifted vertically by the winding frame.

[0020] The present invention is further configured as follows: a control motor is fixedly connected to the top of the limit frame, an output end of the control motor passes through the limit frame and is fixedly connected to a screw rod, an outer side of the screw rod is rotationally connected to the limit frame, and an outer side of the screw rod is threadedly connected to a transmission block.

[0021] By adopting the above technical solution, a control motor is set to drive the screw rod to rotate. When the screw rod rotates, the transmission block connected to it will move vertically along the limit frame to drive the door panel to rise or fall.

[0022] The present invention is further configured as follows: a hollow frame is fixedly connected to the outer side of the first air duct, the top of the hollow frame is fixedly connected to the fan, a hanging bracket is fixedly connected to the outer side of the second air duct, the hanging bracket is fixedly connected to the rear side of the transparent cover, the evaporator is externally connected to a cooling circulation system, a pump is fixedly connected to the top of the hollow frame, and the output end of the pump is fixedly connected to the spray pipe.

[0023] By adopting the above technical solution, a hollow frame is set up to facilitate providing installation space for the structure. The setting of the bracket is used to stabilize the connection of the second air duct. The external cooling circulation system is used to cool the heat exchange medium inside the evaporator. The pump is used to extract water from the simulated environment and supply it to the spray pipe.

[0024] The present invention is further configured as follows: a support leg is provided at the bottom of the outer side of the transparent cover, a secondary beam is fixedly connected to the outer side of the support leg, an electric cylinder is fixedly connected to the bottom of the secondary beam, and a blocking piece is provided at the bottom of the tray rack.

[0025] By adopting the above technical solution, the support legs are provided to stably place the structure, and the auxiliary beam is provided in conjunction with the electric cylinder to support and control the blocking piece.

[0026] The present invention is further configured as follows: the front side of the blocking piece is rotatably connected to the front side of the bottom of the tray frame through a hinge, the bottom of the blocking piece is fixedly connected to a guide rail, the telescopic end of the electric cylinder is rotatably connected to a slider, and the outer side of the slider is slidably connected to the guide rail.

[0027] By adopting the above technical solution, by setting a hinge and a tray rack connection, the sealing piece can be easily rotated along the front side of the bottom of the tray rack to expose the bottom or form a relatively sealed space. The provided slider cooperates with the guide rail to prevent the sealing piece from getting stuck when the electric cylinder pushes and pulls the sealing piece.

[0028] The present invention is further configured as follows: a control motor is fixedly connected to the rear side of the transparent cover, an output end of the control motor passes through the transparent cover and is fixedly connected to a crankshaft, and a bottom of the crankshaft is rotatably connected to a balance frame.

[0029] By adopting the above technical solution and setting a control motor, it is possible to drive the right side of the balance frame to push and pull reciprocatingly in the vertical direction through the crankshaft, so as to drive the balance frame to shake.

By setting the tension spring 18 to cooperate with the drawer 19, when fixing a battery of a larger size, the drawer 19 can be pulled out from the inner side of the pressing frame 508. At this time, the tension spring 18 is stretched, and after being stuck outside the battery, the tension spring 18 pulls the drawer 19 back to the inner side of the pressing frame 508 to match the size of the battery for fixing. The inner side of the sleeve 506 is fixedly connected with a spacer 20, and the spacer 20 The inner side is slidably connected with a sleeve 21, and the inner side of the sleeve 506 is filled with viscous oil. The top and bottom of the inner side of the spacer 20 are provided with flow holes. The bottom of the sleeve 21 is fixedly connected to the slide post 507. By setting the spacer 20 to cooperate with the sleeve 21, when the fixing frame 503 fixes the battery, the slide post 507 is stressed, and the sleeve 21 connected thereto will move along the spacer 20, and push the internal viscous oil to flow along the flow hole. The top of the inner side of the sleeve 506 is fixedly connected with a pressure spring 37, and the bottom of the pressure spring 37 is fixed to the sleeve 21. The bottom of the slide post 507 penetrates the sleeve 506 and the fixing frame 503 and is slidably connected to the sleeve 506. By setting the pressing spring 37, the pressing spring 37 always presses the sleeve 21, so that the slide post 507 connected thereto is always close to the battery. When simulating a vibration or shaking environment, if the battery is subjected to a force that may cause it to move, the pressing frame 508, the slide post 507 and the sleeve 21 in contact therewith will be affected by the hydraulic damping, so they will not be directly displaced, thereby reducing the possibility of the battery being loosened. Fixing the battery is a continuous and slow process, so the sleeve 21 will promote the circulation of viscous oil and press the reset spring 405, so that it can be normally fitted with batteries of different sizes. The rear side of the transparent cover 2 is fixedly connected with a control motor 34, and the output end of the control motor 34 passes through the transparent cover 2 and is fixedly connected with a crankshaft 35, and the bottom of the crankshaft 35 is rotatably connected to the balance frame 402. By setting up the control motor 34, it is convenient to drive the right side of the balance frame 402 to perform reciprocating push and pull in the vertical direction through the crankshaft 35, so as to drive the balance frame 402 to shake.

[0053] Working principle of this embodiment: When installing the battery, place the battery on the bent frame 502, and then rotate the fixing frame 503 along the hinge to make the battery stuck on the inner side of the fixing frame 503. According to the different specifications of the battery, the slide column 507 and the pressure frame 508 at the bottom will press against the top of the battery, and then the slide column 507 will slide along the sleeve 506 to adapt to the size of the battery for fixing. By setting the spacer 20 to cooperate with the sleeve 21, when the fixing frame 503 fixes the battery, the slide column 507 is stressed, and the sleeve 21 connected to it will move along the spacer 20 and push the internal viscous oil along the flow hole Flow, when conducting vibration or shaking tests, the battery and the balance frame 402 will shake, but the pressure frame 508, the sliding column 507 and the sleeve 21 will be affected by the hydraulic damping and will not be directly displaced, thereby reducing the possibility of the battery loosening. When conducting the shaking test, the control motor 34 drives the right side of the balance frame 402 to push and pull reciprocatingly in the vertical direction through the crankshaft 35 to drive the balance frame 402 to shake. One side of the balance frame 402 can be vertically pressed down and pulled up. At this time, the entire balance frame 402 will repeatedly shake along the limit frame 3 through the short axis 401 to simulate the working condition of the battery under shaking conditions.
