Description

Technical Field

[0001] The invention relates to a multi-size compatible battery packaging and transportation device. Background Art

[0002] The existing new energy vehicle battery transport packaging can only be used for a single battery type, which means that each battery size requires a specific packaging size. Due to the rapid annual introduction of new energy vehicle models, the battery life of new energy vehicles is constantly changing. If the battery size changes, the existing packaging will generally have to be scrapped. In addition to the direct cost, the relative opportunity cost is also high.

[0003] Since new energy vehicle batteries come in various sizes, the outer dimensions of the packaging used for production also vary. Therefore, during logistics transportation and storage, batteries of the same type can only be stacked, resulting in a decrease in transportation loading rate and warehouse utilization rate indicators.

[0004] Nowadays, the accuracy and high efficiency of logistics operations, as well as precise cost control, require increasingly higher online data requirements for the quantity, location, and planning control of logistics packaging. Installing high-reliability chips has become a necessary condition. Summary of the Invention

[0005] In order to solve the above problems existing in the prior art, the present invention proposes a multi-size compatible battery packaging and transportation device.

[0006] The present invention can be implemented through the following technical solutions:

[0007] A multi-size compatible battery packaging and transportation device includes a protective shell, a spring, a positioning block, and a polyurethane block. The polyurethane block encloses a magnet block. The positioning block is divided into a support platform and a positioning platform. A casting tube is provided under the positioning platform, which passes through the support platform and the spring. The spring is located in the protective shell and connected to the support platform. The polyurethane block is located above the positioning platform, contacts the parts, and is fixed to the support platform. The protective shell half encloses the support platform and fixes the range of motion of the support platform. A bottom electromagnetic generator is provided under the spring.

[0008] The bottom electromagnetic generating device presets a pressure value, which is determined by the packaging pressure required for different types of batteries. The pressure sensor provided in the bottom electromagnetic generating device is a patch-type flexible film pressure sensor, which collects the pressure signal of the contact surface between the top magnet block and the battery; when the bottom electromagnetic generating device is started, the pressure detected by the pressure sensor is collected in real time and compared with the preset pressure value. When the detected pressure is less than the preset pressure value, the current in the bottom electromagnetic generating device is increased, the magnetic field is enhanced, and the packaging pressure is increased, and vice versa.

[0009] Furthermore, the support platform and the protective shell are fixed by screws and nuts.

[0010] Furthermore, the polyurethane block moves up and down through the spring, and the maximum range of movement is controlled by the tightening position of the screw and the size of the magnetic field generated by the bottom electromagnetic generating device.

[0011] Furthermore, the top and side edges of the polyurethane block are chamfered and fixed on the support platform; the upper half of the support platform and the positioning platform are located inside the polyurethane block and are used to fix the polyurethane block, and the surface of the lower half of the support platform is fitted with the polyurethane block, and the shape of the support platform is concave.

[0012] Furthermore, the long side of the protective shell is symmetrically cut at four points for installing the screws and nuts, the top is open, the interior is hollowed out for placing the support platform and the polyurethane block, and the high sides are rounded; under normal circumstances, the spring is in a relaxed state to support the support platform, at which time the upper part of the screw rod is in contact with the upper part of the hole in the protective shell, and the lower part of the screw rod is in contact with the lower part of the support platform; when subjected to pressure, the spring is tightened, at which time the lower part of the screw rod is in contact with the lower part of the hole in the protective shell, and the upper part of the screw rod is in contact with the upper part of the support platform.

[0013] Furthermore, the battery transport packaging device is in the shape of a rectangular parallelepiped as a whole.

[0014] The present invention has the following beneficial effects:

[0015] 1. Since the product is recycled, it can save a lot of materials and material reprocessing costs;

[0016] 2. Previously, the size changes of new energy vehicle batteries necessitated constant investment in packaging equipment to adapt to them, which not only resulted in high manufacturing costs but also significantly increased logistics and operating costs. With the new equipment, aside from a one-time investment, there is virtually no need for new packaging investment for subsequent battery size changes, resulting in significant economic benefits.

[0017] 3. The present invention is easy to operate and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 This is a flow chart of increasing and decreasing the current of the bottom electromagnetic generating device in the present invention;

[0020] Figure 3 This is a schematic diagram of the present invention in use.

[0021] In the figure, 1 is a polyurethane block; 2 is a positioning platform; 3 is a casting tube; 4 is a support platform; 5 is a spring; 6 is a protective shell; 7-2 is a nut; 8-2 is a screw; and 9 is a magnet block. DETAILED DESCRIPTION

[0022] The following describes the embodiments of the present invention through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0023] like Figure 1 3, a multi-size compatible battery packaging and transportation device of the present invention is a rectangular parallelepiped as a whole, including a protective shell 6, a spring 5, a positioning block, and a polyurethane block 1. The polyurethane block 1 contains a magnet block 9. The positioning block is divided into a support platform 4 and a positioning platform 2. A casting pipe 3 is provided under the positioning platform 2. The casting pipe 3 passes through the support platform 4 and the spring 5. The spring 5 is located in the protective shell 6 and is connected to the support platform 4. The polyurethane block 1 is located above the positioning platform 2 and contacts the parts and is fixed on the support platform 4. The protective shell 6 half wraps the support platform 4, fixes the range of movement of the support platform 4, and a bottom electromagnetic generating device 10 is provided under the spring.

[0024] The support platform 4 and the protective shell 6 are fixed by screws 8 - 2 and nuts 7 - 2 .

[0025] The polyurethane block 1 moves up and down through the spring, and the maximum range of movement is controlled by the screw tightening position and the magnetic field size generated by the bottom electromagnetic generating device.

[0026] like Figure 2 As shown, the bottom electromagnetic generating device 10 presets a pressure value, which is determined by the packaging pressure required by different types of batteries. The pressure sensor provided in the bottom electromagnetic generating device 10 uses a patch-type flexible film pressure sensor, which collects the pressure signal of the contact surface between the top magnet block 9 and the battery. When the bottom electromagnetic generating device 10 is started, the pressure detected by the pressure sensor is collected in real time and compared with the preset pressure value. When the detected pressure is less than the preset pressure value, the current in the bottom electromagnetic generating device is increased, the magnetic field is enhanced, and the packaging pressure is increased, and vice versa. The pressure between the polyurethane-coated magnet block and the battery can be expressed as , where G is the gravity of the polyurethane-coated magnet, K is the spring constant, is the vacuum permeability, which is 4π×10 -7 Henry / meter. A is the cross-sectional area of ​​the core, is the magnetic flux leakage coefficient, set to 1.5, δ is the air system length, N is the number of coil turns, and I is the current. The formula shows that simply adjusting the current can adjust the pressure between the polyurethane-coated magnet and the battery.

[0027] The protective shell 6 is fixed on the fixed main body plane position on the parts rack.

[0028] The present invention selectively adds a spring component to make the fixed positioning block mobile, divides the positioning block into two parts, fixes them with screws and nuts, and adds a spring inside to make the polyurethane block part have the elasticity of moving up and down on a stable basis; the polyurethane block is square, with chamfered top and side edges, and is fixed on the support platform; the positioning platform part of the upper part of the support platform is located inside the polyurethane block to fix the polyurethane block, and the upper surface of the lower part of the base fits with the polyurethane block, and the base shape is concave, so that the support platform is better fixed during casting and more materials are saved; the long side of the protective shell is symmetrically cut into four parts for installing screws and nuts, the top is opened, and the interior is hollowed out for placing the support platform and the polyurethane block, and the high side is rounded. Under normal circumstances, the spring is in a relaxed state to hold up the support platform, at which time the upper part of the screw rod is in contact with the protective shell The top of the opening fits in with the bottom of the screw rod, and the bottom of the screw rod fits in with the bottom of the support platform; when under pressure, the spring is compressed, and at this time the bottom of the screw rod fits in with the bottom of the hole in the protective shell, and the top of the screw rod fits in with the top of the support platform; the polyurethane block is in direct contact with the part, supporting and protecting the part from deformation, reducing the wear of the part caused by the friction between the positioning block and the part, so that the part does not move during transportation, and plays a positioning role when the part is installed; the spring component allows the polyurethane and the support platform to move up and down to a certain extent, which can better protect the parts when facing bumps and other situations during transportation; the protective shell is fixed on the shelf to ensure that the protective shell will not move, and the screws and nuts connect the shell to the support platform to ensure that the support platform will not separate from the protective shell.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
