[0048] Embodiment 1

[0049] First reference Figure 1 , Figure 2 and Figure 3 , describing the structural schematic diagram of the turnover rack of the new energy vehicle battery according to the embodiment of the present application.

[0050] like Figure 1 As shown, the turnover rack of the present invention is used in the turnover, storage and other processes of new energy vehicle batteries. The turnover rack of the present invention includes a chassis, a plurality of limiters and a plurality of positioning assemblies. The upper surface of the chassis is used to place the new energy vehicle battery; a plurality of limiters are distributed and connected to the upper surface of the chassis, and a plurality of limiters are used to stop the outer side walls of the new energy vehicle battery, and a plurality of limiters cooperate to limit the sliding of the new energy vehicle battery on the upper surface of the chassis; a plurality of positioning assemblies are distributed and connected to the upper surface of the chassis, and the positioning assemblies have a locked state and an unlocked state that can be switched with each other. Among them, in the locked state, the positioning assembly contacts and stops the upper surface of the new energy vehicle battery, and a plurality of positioning assemblies cooperate to limit the movement of the new energy vehicle battery in the vertical direction. In the unlocked state, the positioning assembly is detached from the upper surface of the new energy vehicle battery.

[0051] The position limiter of the present invention effectively limits the sliding of the battery on the upper surface of the chassis by stopping the outer side wall of the new energy vehicle battery, thereby ensuring the stability of the battery during transportation. The coordinated use of multiple position limiters simplifies the placement and fixing process of the battery, making the operation more convenient and quick.

[0052] The positioning assembly of the present invention has a locked state and an unlocked state that can be switched to each other. This design makes the loading and unloading of the battery more flexible. In the locked state, the positioning assembly contacts and stops the upper surface of the new energy vehicle battery. Multiple positioning assemblies cooperate to limit the movement of the new energy vehicle battery in the vertical direction, thereby enhancing the fixation of the battery. The positioning reduces the movement of the battery on the turnover rack, thereby reducing the potential safety risks caused by the displacement of the battery.

[0053] In the optimized design of the turnover rack of the present invention, the limiter and the positioning assembly are two key components, and the combination of the two improves the safety of the battery during turnover, storage, etc.

[0054] (I) About the chassis of this application:

[0055] The chassis of the present invention is the supporting core of the entire turnover rack, and its structural design focuses on providing sufficient load-bearing capacity and structural stability. The chassis adopts a sturdy frame structure to ensure that its rigidity and durability are maintained during dynamic turnover and storage. The structural design of the chassis is intended to achieve multiple key functions: bearing the weight of the battery, providing a stable placement platform, and allowing multiple turnover racks to be stacked on each other. Specifically, the size and shape of the chassis will be designed according to the specifications of the battery to match and be compatible with the specifications of the battery.

[0056] like Figure 1 As shown, in a specific implementation, the chassis of the present invention is a rectangular hollow frame structure formed by welding a plurality of square tubes. The chassis of the present invention adopts a rectangular hollow frame structure formed by welding rectangular tubes. This frame design provides higher stability and load-bearing capacity. At the same time, the hollow structure helps to reduce the overall weight and achieve lightweight. The use of square tubes increases the rigidity and impact resistance of the chassis.

[0057] Specifically, the square tube is made of Q235 steel, and the wall thickness of the square tube is 2 mm. Specifically, the bottom frame includes an upper frame and a lower frame, and the upper frame and the lower frame are welded by a plurality of short square tubes to obtain a hollow rectangular frame structure.

[0058] In a preferred embodiment, the upper frame is a grid structure formed by welding multiple square tubes. The upper frame of the chassis is connected to a plurality of placement racks, which are used to contact the lower surface of the new energy vehicle battery. The placement rack is a structure that independently supports the new energy battery in the chassis. On the other hand, it can also raise the height of the new energy vehicle battery from the ground. Such a design can relatively reduce the thickness of the frame structure, thereby reducing the use of square steel materials; on the other hand, the placement rack can ensure that the battery maintains a certain distance from the ground, reducing the impact of moisture on the battery pack.

[0059] Specifically, the rack includes 1 main support beam and 2 auxiliary support beams, and the 1 main support beam and the 2 auxiliary support beams are welded through a plurality of connecting square tubes. The ends of the 1 main support beam and the 2 auxiliary support beams are welded to the upper frame, and the overall shape of the rack is like a π shape.

[0060] In a preferred embodiment, the upper surface of the chassis is connected with a plurality of steel plates, and the outer surface of the steel plates is provided with a rubber layer, and the rubber layer is used to contact the lower surface of the new energy vehicle battery. Specifically, the steel plates are welded on the placement frame.

[0061] The steel plate has a larger surface area and can provide better support. And a rubber layer is provided on the outer surface of each steel plate. The rubber layer serves as a buffer medium between the steel plate and the new energy vehicle battery. It is designed to provide additional protection when the battery pack is placed to prevent the bottom of the battery pack from directly contacting the hard steel plate and causing scratches or damage. The use of the rubber layer not only increases the protection of the battery pack, but also helps to reduce vibration and noise, especially when the battery pack is being handled or transported. In addition, the rubber layer also provides a good anti-slip function, ensuring that the battery pack is stably placed on the steel plate and is not easy to slide. Through this design, the chassis can provide a safer and more stable support platform for new energy vehicle batteries, and better protection for new energy batteries.

[0062] In a preferred embodiment, the upper surface of the base frame has a plurality of support columns, and the support columns are used for stacking a plurality of turnover racks. The lower surface of the base frame has a plurality of recessed portions adapted to the support columns; wherein, when any two turnover racks are stacked up and down, the top end of the support column of the turnover rack located at the bottom is inserted into the recessed portion of the turnover rack located at the top.

[0063] In a specific implementation, the base frame has four support columns and four recessed parts, and the four support columns are respectively located at four corners of the base frame. The four recessed parts of the base frame are correspondingly arranged below the four support columns.

[0064] The upper surface of the chassis is designed with multiple support columns, which allow multiple turnover racks to be stacked on top of each other, improving the space utilization and transportation efficiency in the turnover rack application scenario. The lower surface of the chassis is designed with multiple recessed parts that match the support columns. This design allows the top of the support column of the turnover rack located below to be inserted into the recessed part of the turnover rack located above, forming an interlocking stacking structure, which enhances the stability of the stacked turnover racks.

[0065] In a specific embodiment, the chassis has four support columns, which are located at the four corners of the chassis. This layout provides balanced support points and reduces the torsion or deviation of the chassis when stacking. Accordingly, the four corners of the chassis or under the support columns are also designed with recessed parts to ensure accurate alignment and stability when stacking.

[0066] In a preferred embodiment, the chassis further comprises a plurality of reinforcing plates, one of the reinforcing plates being bolted to the outer side wall of one of the support columns; wherein the plurality of support columns are arranged around the periphery of the plurality of limiters and the plurality of positioning components. Specifically, the reinforcing plate comprises a first plate body and a second plate body formed by bending, and the outer contours of the first plate body and the second plate body are both triangular structures.

[0067] The reinforcing plate is preferably made of steel, and the same Q235 steel can be used. In the optimized design of the structure, the reinforcing plate is connected to the outer wall of the support column by bolts, which enhances the connection strength between the support column and the chassis frame. The reinforcing plate can effectively disperse the load borne by the support column and improve the load-bearing capacity and stability of the entire chassis. In the shape design of the reinforcing plate, the reinforcing plate adopts a first plate body and a second plate body formed by a bending process, and the outer contours of both are triangular structures. The triangular structure has extremely high stability due to its geometric characteristics. This design enables the reinforcing plate to provide better support when bearing loads.

[0068] (II) Regarding the limiter of this application:

[0069] In a specific implementation, the limiter is an angle iron, a connecting flange is provided at the bottom of the limiter, and the limiter is bolted to the base frame. The outer side wall of the limiter is connected to an ABS plastic part, and the ABS plastic part is used to contact the outer side wall of the new energy vehicle battery.

[0070] In the present invention, the limiter adopts an angle iron design, and a connecting flange is provided at the bottom, which is connected to the base frame by bolts. This design makes the installation and adjustment of the limiter simple and quick, and the installation position of the limiter can be adapted and adjusted according to the size of the new energy vehicle battery. In the optimized design of the limiter, the outer wall of the limiter is connected with an ABS plastic part. When this plastic part contacts the outer wall of the new energy vehicle battery, it can provide a certain protection to prevent the battery from being damaged during transportation or storage, and also avoid the outer wall of the battery from directly contacting the angle iron.

[0071] In this field, the overall shape of new energy vehicle batteries is roughly rectangular. For this reason, the turnover frame of the present application adopts 4 limiters, which are connected to the outer square tube of the upper frame of the chassis. The 4 limiters are set corresponding to the four corners of the new energy vehicle battery to limit the corners of the new energy vehicle battery. With the angle iron design, a limiter can effectively form a limit stop for the two outer side walls of the new energy vehicle battery, saving the use of parts.

[0072] In a preferred embodiment, the outer wall of the position-limiting member has a plug-in slot, the ABS plastic member is embedded in the plug-in slot, and the ABS plastic member is bolted to the position-limiting member. The ABS plastic member also adopts an angle iron structure.

[0073] Through this design, the outer wall plug-in groove of the limiter and the embedded and bolted connection design of the ABS plastic part provide a stable, reliable and easy-to-maintain connection method, which helps to protect the battery from damage while ensuring the stability and safety of the turnover rack during use.

[0074] like Figure 1As shown, the positioning assembly includes a mounting seat and a positioning member. The mounting seat is connected to the upper surface of the chassis. The positioning member is hinged to the mounting seat, and the positioning member is used to contact and stop the upper surface of the new energy vehicle battery in a locked state. Wherein, the mounting seat has a locking member, and in the locked state, the locking member can be matched and connected with the positioning member, and the locking member is used to lock the rotation of the positioning member.

[0075] It is understandable that the positioning member is hinged to the mounting seat, and the positioning member can rotate around the hinge. When the new energy battery needs to be locked, the positioning member can be swung to the locking position. When the new energy battery needs to be contact-locked, the positioning member only needs to be rotated from the locking position to the unlocking position. The design of the positioning assembly provides a stable and flexible way to fix the new energy vehicle battery, ensuring the safety and stability of the battery on the turnover rack, while allowing quick loading and unloading, improving operational efficiency.

[0076] Specifically, the positioning member has a connecting portion and a positioning portion that are vertically distributed to each other, and the connecting portion is hinged to the mounting seat. The outer wall of the positioning portion is sleeved with a plastic member, and the positioning portion is used to contact and stop the upper surface of the new energy vehicle battery in a locked state.

[0077] By sleeve-mounting a plastic part on the outer wall of the positioning part, this design can provide protection when the positioning part contacts the battery, avoiding scratches or damage to the battery surface. Locking and unlocking of the positioning part: In the locked state, the plastic part of the positioning part contacts the upper surface of the battery, and the positioning part is fixed by the locking part on the mounting seat to prevent it from rotating. In the unlocked state, the locking part releases the positioning part, allowing the positioning part to rotate around the hinge point of the connecting part to the unlocked position, which is convenient for loading and unloading the battery.

[0078] The design of the positioning assembly helps stabilize the battery on the turnover rack, especially in the vertical direction, to prevent the battery from shaking up and down due to vibration. The plastic parts of the positioning part provide protection for the battery surface to prevent damage during the fixing and positioning process. The design of the positioning assembly provides a stable and flexible way to fix the new energy vehicle battery, ensuring the safety and stability of the battery on the turnover rack, while allowing quick loading and unloading and improving operational efficiency. The application of plastic parts also increases the protection of the battery and prevents potential damage.

[0079] In a specific implementation, the locking member is a latch, and the mounting seat and the lock have respective insertion holes adapted to the latch. When the locking member is connected with the positioning member, the locking member is sequentially inserted into the mounting seat insertion hole and the first through hole of the mounting seat to lock the rotation of the mounting seat through the first limiting member.

[0080] In the present invention, the bolt is used as a locking member to fix the positioning member in a locked state to prevent it from rotating around the hinge point. The mounting seat and the positioning member are both designed with a plug hole adapted for the bolt, and the bolt can be inserted into the plug hole to achieve locking of the positioning member.

[0081] Locking process of the locating piece: When the connection is matched to lock the locating piece, the pin will pass through the socket of the mounting seat and the socket of the locating piece in turn, thereby locking the locating piece. It is understandable that at this time the locating piece cannot rotate around the hinge and the position is locked. The stability of the locating piece in the locked state is ensured by the pin, providing a solid stop for the new energy vehicle battery. The locking mechanism prevents the locating piece from rotating unnecessarily, improving the safety of the battery on the turnover rack. The design of using the pin as a locking piece is simple and reliable, easy to operate and maintain. The design of the pin allows for quick locking and unlocking of the locating piece, improving the efficiency of battery loading and unloading. Unlock: Pull out the pin so that the locating piece can rotate freely to unlock.

[0082] In summary, the design of this locking mechanism provides a simple, fast and reliable method to fix and unlock the positioning parts of new energy vehicle batteries, ensuring the stability and safety of the batteries on the turnover rack.

[0083] Embodiment 2

Specifically, the product structure and technical principle of the second embodiment are exactly the same as those of the first embodiment.

[0096] The rubber mix was left for more than 16 hours, and the vulcanization curve of the rubber mix at 160°C was measured on the RPA to obtain the process positive vulcanization time (t90). The vulcanization time was determined based on t90 and the thickness of the vulcanized sample. The rubber was vulcanized on a flat plate vulcanizer with a vulcanization pressure of 10 MPa.

[0097] Wherein, ANFs is aramid nanofiber, the content of ANFs in the ANFs pre-dispersion is 30%, and the AFS pre-dispersion is made of ANFs and nitrile latex.

[0098] Specifically, the ANFs pre-dispersion is prepared by the following method: ANFs and nitrile latex are weighed in a certain ratio, the nitrile latex is gradually added to the ANFs-water dispersion, and after stirring and mixing evenly, an 8% (mass fraction) calcium chloride aqueous solution is added dropwise for flocculation and sedimentation, and the obtained pre-mix is ​​squeezed out of part of the water in an open mill, and finally dried in an oven at 60° C. to constant weight.
