Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to a shell assembly, a method for disassembling a shell assembly, a battery pack, and an electrical device. Background Art

[0002] With the development of the new energy industry, batteries are widely used. When the new energy battery pack is repaired or recycled, the outer shell is difficult to disassemble due to the high bonding strength of the structural adhesive. In the related art, the disassembly methods of the outer shell usually include high-temperature disassembly, low-temperature disassembly, chemical disassembly and mechanical disassembly. On the one hand, the melting temperature of the colloid in high-temperature disassembly far exceeds the safe use temperature of the battery cell, which poses a safety risk. On the other hand, the plastic shell will also melt and soften. Low-temperature disassembly takes a lot of time and has poor energy efficiency. Chemical methods of degumming require the use of a large amount of toxic and highly corrosive organic solvents. Mechanical disassembly can easily cause damage to the structural parts and cannot be reused, resulting in material loss. All of the above disassembly methods have the problem of inconvenient disassembly. Summary of the invention

[0078] The following specific embodiments are exemplary and non-limiting, and are intended to provide a basic understanding of the present application, and are not intended to identify the key or decisive elements of the present application or to limit the scope of protection. As long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.

[0079] When a component is considered to be “provided on” another component, it can be directly provided on the other component or there may be a component in between. When a component is considered to be “connected to” another component, it can be directly connected to the other component or there may be a component in between.

[0080] It can be understood that the terms "perpendicular, equal" are used to describe an ideal state between two components. In actual production or use, there may be a state between two components that is approximately perpendicular or equal. For example, in combination with numerical descriptions, perpendicularity can refer to the angle between two straight lines being in the range of 90°±10°, perpendicularity can also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicularity can also refer to the angle between a straight line and a plane being in the range of 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0081] The terms “vertical”, “horizontal”, “left”, “right”, “top”, “bottom”, “front”, “back” and similar expressions used in this document are for illustrative purposes only and are not intended to limit this application.

[0082] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components may be approximately parallel. For example, combined with numerical descriptions, parallel can refer to the angle between two straight lines being between 180°±10°, parallel can also refer to the dihedral angle between two planes being between 180°±10°, and parallel can also refer to the angle between a straight line and a plane being between 180°±10°. The two components described as "parallel" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0083] Unless otherwise defined, when the term "plurality" is used to describe the number of components, it specifically means that the components are two or more.

[0084] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and examples can be combined with each other.

[0085] See also Figure 1 and Figure 2 One embodiment of the present application provides a housing assembly 100, including a first housing 101, a second housing 102, an adhesive component 103, and a disassembly component 104.

[0087] The operator pulls the disassembly component 104 out of the first shell 101 and the second shell 102, thereby taking out the adhesive component 103, which is conducive to the rapid disassembly of the shell assembly 100.

At the same time, the damage of the shell assembly 100 is reduced, and the shell assembly 100 can be reused, reducing material loss.

[0088] Optionally, the adhesive member 103 includes glue, such as polyurethane glue.

[0089] In some embodiments, the adhesive member 103 is a two-component adhesive composition consisting of a resin component and a curing agent component.

[0090] In some embodiments, the first housing 101 and the second housing 102 are connected to form a receiving space for receiving the protected object. The adhesive 103 bonds the first end surface 101 b and the second end surface 102 b to enhance the sealing performance of the housing assembly 100 .

[0091] See also Figure 2 , Figure 3 as well as Figure 4 In some embodiments, the first shell 101 includes a first front wall 1011, a first rear wall 1012, a first top wall 1013, a first bottom wall 1014 and a first side wall 1015.

The second front wall 1021, the second rear wall 1022, the second top wall 1023, and the second bottom wall 1024 are connected to the end face of the second shell 102 to form a second end face 102b.

[0093] In some embodiments, the first receiving space 101a and the receiving space 102a form a receiving space.

[0094] See also Figure 2 , Figure 3 as well as Figure 4 In some embodiments, the first end surface 101b and the second end surface 102b are both flat surfaces. All positions of the first end surface 101b are located in the same plane, and all positions of the second end surface 102b are located in the same plane, which is conducive to the adhesive 103 bonding the first end surface 101b and the second end surface 102b.

[0095] In some embodiments, the first shell 101 and the second shell 102 are arranged along the first direction X, and the first end surface 101 b and the second end surface 102 b are perpendicular to the first direction X.

[0096] In some embodiments, the first end surface 101b is provided with a first positioning groove (not shown), which is recessed into the first shell 101, and the disassembly component 104 can be partially inserted into the first positioning groove, which is conducive to positioning and installing the disassembly component 104 on the first end surface 101b.

[0097] In other embodiments, the second end surface 102b is provided with a second positioning groove (not shown), which is recessed into the second shell body 102, and the disassembly component 104 can be partially inserted into the second positioning groove, which is conducive to positioning and installing the disassembly component 104 on the first end surface 101b.

[0098] See also Figure 2 and Figure 5In some embodiments, the disassembly component 104 includes a first part 1041 and a second part 1042, and the first part 1041 is connected to the second part 1042. The first part 1041 is embedded in the adhesive component 103, and the second part 1042 is located outside the first shell 101 and the second shell 102. The second part 1042 is configured to be operated by an operator. The operator pulls the second part 1042 to drive the first part 1041 to separate from the first shell 101 and the second shell 102, thereby achieving the purpose of quickly and easily disassembling the shell assembly 100.

[0099] In some embodiments, the second portion 1042 is a pull ring.

[0100] In some embodiments, the first portion 1041 is a steel wire.

[0101] In some embodiments, the second shell 102 is provided with a receiving groove 105, and the second part 1042 is disposed in the receiving groove 105, thereby reducing the space occupied by the second part 1042 and improving space utilization.

[0102] In some other embodiments, the first housing 101 is provided with a receiving groove 105 , and the second portion 1042 is disposed in the receiving groove 105 .

[0103] In some embodiments, the housing assembly 100 includes a protective member 106 , which covers the receiving groove 105 , thereby limiting the second portion 1042 from being disengaged from the receiving groove 105 , reducing the risk of the second portion 1042 being accidentally pulled, and improving the safety of the housing assembly 100 .

[0104] Optionally, the protection member 106 may be an insulating member, such as an insulating film. By using the insulating film to cover the receiving groove 105, the space occupied by the protection member 106 can be reduced while playing an insulating role.

[0105] Optionally, the protective member 106 may be a cover plate, which detachably covers the receiving groove 105, so as to facilitate quick and easy removal of the cover plate and improve the disassembly convenience of the housing assembly 100.

[0106] In some embodiments, the housing assembly 100 includes a handle 107, the handle 107 includes a first connection portion 1071, a second connection portion 1072, and a grip portion 1073 located between the first connection portion 1071 and the second connection portion 1072, the first connection portion 1071 is fixed to the first housing 101, the second connection portion 1072 is fixed to the second housing 102, and the grip portion 1073 is located above the receiving groove 105 to hide the position of the receiving groove 105. When the housing assembly 100 is subjected to external forces such as a drop impact, the influence of the external force on the position of the receiving groove 105 is reduced, and the structural stability of the housing assembly 100 is improved.

[0107] See also Figure 2 , Figure 6 and Figure 7 In some embodiments, the first portion 1041 includes a main body portion 1041 a and a protruding portion 1041 b , and both the protruding portion 1041 b and the main body portion 1041 a are bonded to the adhesive member 103 .

[0108] In some embodiments, the protrusion 1041b is integrally formed on a side of the main body 1041a.

[0109] In other embodiments, the protrusion 1041b is fixedly connected to the side of the main body 1041a by welding, bonding, or winding fixation.

[0110] In some embodiments, the protrusion 1041b faces the inside of the housing assembly 100, which helps to reduce the impact of the protrusion 1041b on the first end surface 101b and the second end surface 102b, and improves the problem of the disassembly component 104 damaging the first end surface 101b and the second end surface 102b.

[0111] In some embodiments, the protrusion 1041b faces the outside of the shell assembly 100. When the operator pulls the disassembly component 104, the protrusion 1041b set toward the outside of the shell assembly 100 can pierce the adhesive component 103 outward, thereby destroying the bonding strength of the adhesive component 103 more effortlessly.

[0112] In some embodiments, there is an angle between the protrusion 1041 b and the main body 1041 a , and the force of the operator pulling the disassembly component 104 is parallel to the extension direction of the protrusion 1041 b .

[0113] In some embodiments, two groups of protrusions 1041b are provided, one group of protrusions 1041b is provided on the side of the main body 1041a facing the inside of the shell assembly 100, and the other group of protrusions 1041b is provided on the side of the main body 1041a facing the outside of the shell assembly 100.

[0114] In some embodiments, the first portion 1041 has a central axis along its length direction, and the first portion 1041 is twisted into a spiral shape around its central axis to form a spiral protrusion on the side of the main body 1041a, thereby increasing the contact area between the first portion 1041 and the adhesive 103. At the same time, the twisted spiral protrusion can increase the squeezing force of the first portion 1041 on the adhesive 103 when the operator pulls the disassembly component 104, so that the disassembly component 104 can be pulled out from the adhesive 103 more effortlessly.

[0115] An embodiment of the present application provides a method for disassembling a housing assembly 100, which is applied to the housing assembly 100 in the above embodiment. The disassembly method includes:

[0116] Pull out the disassembly component 104: The operator pulls the disassembly component 104, and the disassembly component 104 is separated from the first shell 101 and the second shell 102. The bonding strength of the adhesive component 103 is reduced by mechanical destruction, so that at least part of the adhesive component 103 is separated from the first shell 101 and the second shell 102 by the disassembly component 104.

[0117] In some embodiments, the operator pulls the disassembly component 104 out of the first shell 101 and the second shell 102 , and takes out the adhesive component 103 .

[0118] In other embodiments, when the operator pulls the disassembling member 104 , part of the adhesive member 103 remains between the first shell 101 and the second shell 102 , and the disassembling member 104 is pulled out from the adhesive member 103 and takes part of the adhesive member 103 away.

[0119] In some embodiments, the disassembly component 104 is conductive. The disassembly method includes, before pulling out the disassembly component 104, passing current through the disassembly component 104, so that the disassembly component 104 generates heat and softens the adhesive component 103 from the inside, which is conducive to improving the accuracy of heating and reducing the impact on the first shell 101 and the second shell 102. Softening means that after the adhesive component 103 is heated by the disassembly component 104, it changes from the original solid state to a semi-fluid state that is easily deformed by the disassembly component 104.

[0120] In some embodiments, to enhance operator protection, a voltage that is safe for the operator may be used, such as a voltage not higher than 36V.

[0121] In another embodiment of the present application, a battery pack 1001 including the above-mentioned shell assembly 100 is provided. The battery pack 1001 includes a battery cell assembly (not shown) and a circuit board (not shown). The battery cell assembly and the circuit board are located in the receiving space.

[0122] Part of the battery cell assembly (not shown) is located in the first receiving space 101 a , and the remaining part of the battery cell assembly (not shown) is located in the first receiving space 101 a , which is convenient for disassembling and repairing the battery pack 1001 .

[0123] Part of the circuit board (not shown) is located in the first receiving space 101a, and the remaining part of the circuit board (not shown) is located in the second receiving space 102a, which is convenient for disassembling and maintaining the battery pack 1001.

[0124] See also Figure 8 The present application also provides an electric device 1000 using the above battery pack 1001.
