Description

Technical Field

[0001] (Cross - reference to related applications) This application claims the benefit of priority based on Korean Patent Application No. 10 - 2023 - 0089139 filed on July 10, 2023, and all the contents disclosed in the literature of the Korean patent application are incorporated herein by reference.

[0002] (Technical Field) The present invention relates to an electronic device, and more particularly, to an electronic device in which a housed secondary battery can be separated without damage.

Background Art

[0003] Secondary batteries are highly applicable to a variety of product groups and have electrical characteristics with a high energy density. Such secondary batteries are applied not only to portable electronic devices but also to electric vehicles or hybrid vehicles driven by an electric drive source, power storage devices, etc. Secondary batteries are attracting attention as a new energy source for environmental friendliness and improvement of energy efficiency not only because of the primary advantage of significantly reducing the use of fossil fuels but also because no by - products are generated during energy use. A secondary battery pack applied to an electric vehicle, etc., has a structure in which a number of secondary battery modules including a plurality of secondary batteries are connected to obtain high output.

[0004] Recently, research has been actively conducted to protect the environment and recycle resources, such as reducing carbon dioxide emissions, by recycling or reusing secondary batteries that have been used in electronic devices and whose life has almost expired. Activation of the secondary battery recycling or reuse industry can reduce the dependence on resource - holding countries of secondary batteries and can have a positive impact on the positive cycle of the secondary battery supply network.

[0005] However, in order to recycle or reuse secondary batteries, a technology is needed to separate them from electronic devices without damaging them. When attempting to separate a secondary battery by inserting a structure into the gap between the electronic device and one side of the secondary battery and applying force, the force concentrates on one or the other side of the secondary battery, causing it to break or bend, thus damaging the battery and making it difficult to recycle or reuse. Therefore, there is a need to develop a technology to solve the aforementioned problems. [Overview of the project] [Problems that the invention aims to solve]

[0006] The present invention aims to solve the aforementioned problems and provides an electronic device that can be separated without damage so that a secondary battery housed inside can be reused. [Means for solving the problem]

The insert unit includes an operation portion; and a deformation portion connected to the operation portion and provided to be deformed by an operation of the operation portion.

[0019] Further, the deformation portion may include a fixed portion fixed to one side of the housing portion; and a non-fixed portion that is deformed by an operation of the operation portion and is provided to push out the secondary battery from the housing portion.

[0020] Further, the non-fixed portion may be provided to be deformed into a convex shape toward the secondary battery by an operation of the operation portion and push out the secondary battery.

[0021] Further, the operation portion may be formed to bend at a predetermined angle with respect to the non-fixed portion from an end portion of the non-fixed portion and extend along the depth direction of the housing portion.

Modes for Carrying Out the Invention

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement it while referring to the accompanying drawings. However, the present invention may be embodied in various different forms and is not limited or restricted by the following embodiments.

[0025] In order to clearly explain the present invention, detailed descriptions of parts not related to the explanation or related known technologies that unnecessarily obscure the gist of the present invention are omitted. When adding reference signs to the components of each figure in this specification, the same or similar reference signs are assigned to the same or similar components throughout the specification.

[0026] Furthermore, the terms and words used in this specification and the claims shall not be interpreted in a manner limited to their ordinary or dictionary meanings, but rather in a manner consistent with the technical idea of ​​the present invention, in accordance with the principle that inventors may define the concepts of terms as appropriate to best describe their invention.

[0027] (First Embodiment) Referring to Figure 1, in a first embodiment of the present invention, the electronic device 10 may include a main body 100, a secondary battery 300, and an insert unit 400.

[0028] The electronic device 10 can mean a device that is electrically driven using a secondary battery 300 as an energy source. The electronic device 10 is not limited to this, but may be, for example, a portable terminal or a notebook computer.

[0029] The main body 100 may contain electronic components necessary for the electronic device to be electrically driven, and the main body 100 may have a recessed housing portion 110 that can accommodate a secondary battery 300, which is an energy source for driving the electronic components.

[0030] The housing section 110 can house the secondary battery 300 so as to electrically connect the secondary battery 300 to the electronic components contained in the main body section 100. The secondary battery 300 may be inserted into the housing section 110 so that its flat surface faces the bottom surface inside the housing section 110. By being inserted into the housing section 110, the secondary battery 300 is electrically connected to the electronic components contained in the main body section 100 and can supply electrical energy.

[0031] The depth of the housing section 110, which is recessed in the main body section 100, may be less than the thickness of the secondary battery 300. Since the thickness of the secondary battery 300 housed in the housing section 110 is greater than the depth of the housing section 110, one side of the battery may protrude from the housing section 110.

[0032] The electronic device 10 may further include a cover 200.

[0033] The cover 200 may be attached to the main body 100 by covering one side of the main body 100 so that the secondary battery 300 is not exposed to the outside of the electronic device 10.

[0034] The cover 200 may be formed to be recessed to a predetermined depth to accommodate the thickness of the secondary battery 300 protruding from the housing 110.

[0035] The secondary battery 300 may include a first electrode assembly (not shown), a second electrode assembly (not shown), and a case (not shown).

[0036] The first electrode assembly may be formed in a first area and configured such that at least one of the first positive electrode, the first negative electrode, and the first separator membrane is stacked on top of each other.

[0037] The first electrode assembly is not limited to this, but may be, for example, a stack-type electrode assembly formed by stacking a first positive electrode and a first negative electrode, with a separation membrane stacked between the first positive electrode and the first negative electrode; a stack-and-folding type electrode assembly in which the first positive electrode and the first negative electrode are alternately stacked by winding the electrode units using a rectangular separation membrane that is longer in the horizontal direction than in the vertical direction; or a jelly roll type electrode assembly wound in one direction with a first negative electrode, a first positive electrode, and a separation membrane interposed between the first negative electrode and the first positive electrode.

[0038] The second electrode assembly may be formed in a second area smaller than the first area, and may be formed so that at least one of the second positive electrode, the second negative electrode, and the second separator membrane is stacked on top of each other.

[0039] The second electrode assembly is not limited to this, but may be, for example, a stack-type electrode assembly formed by stacking a second positive electrode and a second negative electrode, with a separation membrane stacked between the second positive electrode and the second negative electrode; a stack-and-folding type electrode assembly in which the second positive electrode and the second negative electrode are alternately stacked by winding the electrode units using a rectangular separation membrane that is longer in the horizontal direction than in the vertical direction; or a jelly roll type electrode assembly wound in one direction with a second negative electrode, a second positive electrode, and a separation membrane interposed between the second negative electrode and the second positive electrode.

[0040] The second electrode assembly is formed on a second area smaller than the first area and is arranged to be stacked on top of the first electrode assembly, so a step may be formed between the first electrode assembly and the second electrode assembly.

[0041] The shape of the second electrode assembly is not limited thereto, but may include, for example, a square shape, a bent shape, or a shape with a groove recessed from one side. Preferably, it may be formed in a square shape, which simplifies the manufacturing process.

[0042] The secondary battery 300 may further include a third electrode assembly.

[0043] The third electrode assembly may be formed in a third area and configured such that at least one of the third positive electrode, the third negative electrode, and the third separator membrane is stacked on top of each other.

[0044] The third electrode assembly is not limited to this, but may be, for example, a stack-type electrode assembly formed by stacking a third positive electrode and a third negative electrode, with a separation membrane stacked between the third positive electrode and the third negative electrode; a stack-and-folding type electrode assembly in which the third positive electrode and the third negative electrode are alternately stacked by winding the electrode units using a rectangular separation membrane that is longer in the horizontal direction than in the vertical direction; or a jelly roll type electrode assembly wound in one direction with a third negative electrode, a third positive electrode, and a separation membrane interposed between the third negative electrode and the third positive electrode.

[0045] The third electrode assembly is formed in a third area smaller than the first area and is arranged to be stacked on top of the first electrode assembly, so a step may be formed between the first electrode assembly and the third electrode assembly.

[0046] The shape of the third electrode assembly is not limited thereto, but may include, for example, a square shape, a bent shape, or a shape with a groove recessed from one side, and preferably, it may be formed in a square shape that is easy to manufacture.

[0047] The third electrode assembly may be positioned on the first electrode assembly such that it is separated from the second electrode assembly by a predetermined distance. Between the third electrode assembly and the second electrode assembly, a groove may be formed along the opposing surfaces of the third electrode assembly and the second electrode assembly, with a depth approximately equal to the thickness of the second and third electrode assemblies, due to a step formed by stacking the third and second electrode assemblies on the first electrode assembly. When the first, second, and third electrode assemblies are housed in a case, the case may be formed to correspond to the shape of the groove, and an insert groove 310 can be formed on the outer surface of the case.

[0048] The case forms the outer surface of the secondary battery and can house the first electrode assembly and the second electrode assembly inside. Furthermore, the case can house the first electrode assembly, the second electrode assembly, and the third electrode assembly.

[0049] The case may be formed from a flexible pouch sheet material that includes a metal layer and an insulating layer.

[0050] The case may be formed in a shape that corresponds to or is similar to the stacked shape of the electrode assemblies housed inside.

[0051] Referring to Figure 2, an insert groove 310 may be formed on the outer surface of the secondary battery 300, extending in one direction from one end corner to a predetermined depth.

[0052] The insert groove 310 may be formed along the width direction or along the length direction of the secondary battery 300.

[0053] The insert groove 310 may be formed on the outer surface of the case by forming the case to enclose the step formed by the first electrode assembly and the second and third electrode assemblies stacked on the first electrode assembly, so as to correspond to the step.

[0054] Since the secondary battery 300 is housed with the insert groove 310 facing the bottom surface of the housing 110, the bottom surface of the insert groove 310 may be separated from the bottom surface of the housing 110 by the depth of the insert groove 310. An insert unit 400 may be inserted into the insert groove 310.

[0055] Referring to Figure 2, the insert unit 400 is configured to separate the secondary battery 300 inserted into the housing 110 of the main body 100 from the housing 110, and may be configured to prevent damage when the secondary battery 300 is separated from the housing 110.

[0056] The insert unit 400 may include an operating section 410 and a deformation section 420.

[0057] Referring to Figures 2 to 4, the insert unit 400 may include a folded shape. The operating portion 410 may be formed to bend at a predetermined angle relative to the deformable portion 420 at the end of the deformable portion 420. Since the operating portion 410 is formed to bend at a predetermined angle relative to the deformable portion 420, by operating one end of the operating portion 410 away from the secondary battery 300, the other end of the operating portion 410 connected to the deformable portion 420 can apply a force in the direction of compressing the deformable portion 420, and the deformable portion 420, subjected to the force, can be deformed by the operating portion 410.

[0058] The operating section 410 may be formed on one side of the secondary battery 300, extending from the deformable section 420 along the thickness direction of the secondary battery 300. Since the length of the operating section 410 is formed to be longer than the depth of the housing section 110, the operating section 410 may be formed to protrude from the housing section 110. The operating section 410 protruding from the housing section 110 can be grasped and operated by the user.

[0059] The operating part 410 may be made of a rigid material so as not to deform even when gripped and operated by the user. When the user operates the operating part 410 so that one end moves away from the secondary battery 300, it may come into contact with the corner of the inner wall of the housing part 110. Since the length of the operating part 410 is longer than the depth of the housing part 110, it is supported by the corner of the inner wall of the housing part 110 that comes into contact with the operating part 410, and a force can be applied in the direction of compressing the deformable part 420 by the principle of leverage.

[0060] The operating part 410 may be formed from a rigid material so as not to deform even when force is applied, allowing force to be applied to the deformable part 420, but is not limited to this; for example, it may be made of plastic, metal, etc. The operating part 410 may be formed to be even more rigid than the deformable part 420.

[0061] The deformable portion 420 may be configured such that its shape is changed by the operation of the operating portion 410 in the insert groove 310, thereby separating the secondary battery 300 from the housing portion 110.

[0062] The deformation portion 420 is formed as an extension of the operating portion 410 and may be arranged along the length or width of the secondary battery 300.

[0063] The deformable portion 420 may be positioned so as to be inserted into the insert groove 310. Since the insert groove 310 is formed in the secondary battery 300, even if the secondary battery 300 is placed in the housing portion 110 after the deformable portion 420 has been inserted into the insert groove 310, the problem of the secondary battery 300 being damaged by the thickness of the deformable portion 420 can be prevented.

[0064] The deformable portion 420 receives a compressive force along its length when operated by the operating portion 410. When subjected to this force, at least a portion of the deformable portion 420 deforms into a convex shape toward the secondary battery 300, pushing the secondary battery 300 outward from the housing portion 110 and separating the secondary battery 300 from the housing portion 110.

[0065] The deformable portion 420 may include an elastically deformable material so that it can be elastically deformed by the operation of the operating portion 410. However, it may be made of, for example, plastic or metal.

[0066] The operating section 410 may be formed to be even more rigid than the deformable section 420 so that it can fully apply force to the deformable section 420 without deforming its shape when operated by the user.

[0067] The deformed portion 420 may include a joint portion 421 and a non-joint portion 422.

[0068] The joint portion 421 may be formed at the end of the deformable portion 420 and joined to one surface of the secondary battery 300. Since the position of the joint portion 421 on one surface of the secondary battery 300 is fixed, when the shape of the deformable portion 420 is deformed by the operation of the operation portion 410, the deformable portion 420 can be guided to deform in a convex shape toward the secondary battery 300. More specifically, the joint portion 421 may be joined to one surface of the insert groove 310 of the secondary battery 300.

[0069] The position of the joint 421 is not limited to this, but may be formed, for example, at the end of the insert groove 310.

[0070] The non-jointed portion 422 is a region that is not joined to the secondary battery 300 by the deformed portion 420, and may be formed extending from the jointed portion 421 along the insert groove 310.

[0071] The non-connecting portion 422 is positioned between the connecting portion 421 and the operating portion 410. When the operating portion 410 is operated, the deformable portion 420 is subjected to a compressive force. As a result, the end of the non-connecting portion 422 is fixed to the secondary battery 300 by the connecting portion 421, and the non-connecting portion 422 can be bent into a convex shape toward the secondary battery 300, thus deforming its shape. The deformed non-connecting portion 422 can push the secondary battery 300 out of the housing portion 110, separating the secondary battery 300 from the housing portion 110.

[0072] Furthermore, since the non-joint portion 422 is formed of an elastically deformable material, it can push out the secondary battery 300 while cushioning any impact the secondary battery 300 may receive when the non-joint portion 422 pushes it out, thereby minimizing damage to the secondary battery 300.

[0073] The non-connecting portion 422 is positioned between the secondary battery 300 and the bottom surface of the housing 110, and pushes the lower surface of the secondary battery 300 that is in contact with the non-connecting portion 422 toward the outside of the housing 110. This prevents the electrode assembly housed inside from being damaged by bending or breaking when the secondary battery 300 is separated from the housing 110.

[0074] (Second Embodiment) Referring to Figures 5 and 6, in a second embodiment of the present invention, the electronic device may include a main body 100, a cover, a secondary battery 300, and an insert unit 500.

[0075] The descriptions of the main body 100, the cover, and the secondary battery 300 are the same as those described above, and can therefore be replaced by those descriptions.

[0076] The insert unit 500 may include an operating section 510 and a deformation section 520.

[0077] The insert unit 500 may include a folded shape. The operating portion 510 may be formed at both ends of the deformable portion 520 and bend at a predetermined angle relative to the deformable portion 520. Since the operating portion 510 is formed to bend at a predetermined angle relative to the deformable portion 520, by operating the terminal end of the operating portion 510 away from the secondary battery 300, the other end of the operating portion 510 connected to the deformable portion 520 can apply force in a direction that compresses the deformable portion 520, and the deformable portion 520, subjected to the force, can be deformed by the operating portion 510.

[0078] The operating section 510 may be formed symmetrically at both ends of the deformation section 520.

[0079] The operating section 510 may be formed on both sides of the secondary battery 300, extending from the deformable section 520 along the thickness direction of the secondary battery 300. Since the length of the operating section 510 is formed to be longer than the depth of the housing section 110, the operating section 510 may be formed to protrude from the housing section 110. The operating section 510 protruding from the housing section 110 can be grasped and operated by the user.

[0080] The operating part 510 may be made of a rigid material so as not to deform even when gripped and operated by the user. When the user operates the operating part 510 so that one end moves away from the secondary battery 300, it may come into contact with the corner of the end of the inner wall of the housing part 110. Since the length of the operating part 510 is longer than the depth of the housing part 110, it is supported by the corner of the inner wall of the housing part 110 that comes into contact with the operating part 510, and a force can be applied in the direction of compressing the deformable part 520 by the lever principle.

[0081] The operating part 510 may be made of a rigid material so as not to deform even when force is applied, and so as to allow force to be applied to the deformable part 520. However, it may be made of plastic, metal, or the like. The operating part 510 may be made to be even more rigid than the deformable part 520.

[0082] The deformation section 520 may be configured such that its shape is changed by the operation of the operating section 510, thereby separating the secondary battery 300 from the housing section 110.

[0083] The deformation portion 520 is formed as an extension of the operating portion 510 and may be arranged along the length or width of the secondary battery 300.

[0084] The deformable portion 520 may be positioned so as to be inserted into the insert groove 310. Since the insert groove 310 is formed in the secondary battery 300, even if the secondary battery 300 is placed in the housing portion 110 after the deformable portion 520 has been inserted into the insert groove 310, the problem of the secondary battery 300 being damaged by the thickness of the deformable portion 520 can be prevented.

[0085] The deformable portion 520 is subjected to a compressive force along its length by operating the operating portions 510 formed on both sides of the deformable portion 520. When subjected to this force, at least a portion of the deformable portion 520 is deformed into a convex shape toward the secondary battery 300, pushing the secondary battery 300 outward from the housing portion 110 and separating the secondary battery 300 from the housing portion 110.

[0086] The deformable portion 520 may include an elastically deformable material so that it can be elastically deformed by the operation of the operating portion 510. However, it may be made of, for example, plastic or metal.

[0087] The operating section 510 may be formed to be even more rigid than the deformable section 520 so that it can fully apply force to the deformable section 520 without deforming its shape when operated by the user.

[0088] The deformed portion 520 may include a jointed portion 521 and a non-jointed portion 522.

[0089] The joint portion 521 may be formed near the longitudinal center of the deformable portion 520 and joined to one surface of the secondary battery 300. Since the position of the joint portion 521 on one surface of the secondary battery 300 is fixed, when the shape of the deformable portion 520 is deformed by the operation of the operation portion 510, the deformable portion 520 can be guided to deform in a convex shape toward the secondary battery 300. More specifically, the joint portion 521 may be joined to the longitudinal center of the insert groove 310 of the secondary battery 300.

[0090] The position of the joint 521 is not limited to this, but may be formed, for example, in the center of the insert groove 310.

[0091] When the shape of the deformable portion 520 is deformed, the joint portion 521, together with the non-joint portion 522, can push the secondary battery 300 out of the housing.

[0092] The non-jointed portion 522 is a region that is not joined to the secondary battery 300 by the deformed portion 520, and may be formed extending from the jointed portion 521 located near the center of the deformed portion 520 along the insert groove 310 in both directions.

[0093] The non-connecting portion 522 is positioned between the connecting portion 521 and the operating portion 510. When the operating portion 510 is operated, the deformable portion 520 is subjected to a compressive force. As a result, the end of the non-connecting portion 522 is fixed to the secondary battery 300 by the connecting portion 521, and the non-connecting portion 522 can be bent into a convex shape toward the secondary battery 300, thus deforming its shape. The deformed non-connecting portion 522, together with the connecting portion 521, can push the secondary battery 300 out of the housing portion 110, separating the secondary battery 300 from the housing portion 110.

[0094] Since the non-connecting portion 522 is positioned between the secondary battery 300 and the bottom surface of the housing 110, when its shape is deformed, it pushes the secondary battery 300 outward from the bottom of the secondary battery 300, thus reducing damage to the secondary battery 300 compared to when a structure is installed in the gap between the end of the secondary battery 300 and the housing 110 to separate the secondary battery 300 from the housing 110. Furthermore, the operating portions 510, which are symmetrically positioned at both ends of the deformable portion 520, can guide the deformable portion 520 to deform symmetrically with respect to the connecting portion 521, so that the secondary battery 300 can be separated from the housing 110 by a uniform force.

[0095] The deformation portion 520 is positioned between the secondary battery 300 and the bottom surface of the housing portion 110, and pushes the area near the center of the bottom surface of the secondary battery 300 outward from the housing portion 110. This prevents the electrode assembly housed inside from being damaged by bending or breaking when the secondary battery 300 is separated from the housing portion 110.

[0096] (Third embodiment) Referring to Figure 7, in a third embodiment of the present invention, the electronic device 11 may include a main body 100, a secondary battery 300, and an insert unit 600.

[0097] The explanation regarding the cover and the secondary battery 300 is the same as the explanation given above, and can therefore be substituted using that explanation.

[0098] The main body 100 may include electronic components necessary for the electronic device 11 to be electrically driven.

[0099] The main body 100 may have a recessed housing section 110 that can accommodate a secondary battery 300, which is an energy source for driving electronic components.

[0100] The insert unit 600 is configured to separate the secondary battery 300 inserted into the housing portion 110 of the main body portion 100 from the housing portion 110, and may be configured to prevent damage to the secondary battery 300 when it is separated from the housing portion 110.

[0101] The insert unit 600 may be mounted in the housing section 110 and, as it deforms, may be configured to separate the secondary battery 300 from the housing section 110.

[0102] The insert unit 600 may include an operating section 610 and a deformation section 620.

[0103] Referring to Figures 8 and 9, the insert unit 600 may include a folded shape. The operating portion 610 may be formed to bend at a predetermined angle relative to the deformable portion 620 at the end of the deformable portion 620. Since the operating portion 610 is formed to bend at a predetermined angle relative to the deformable portion 620, by operating one end of the operating portion 610 away from the secondary battery 300, the other end of the operating portion 610 connected to the deformable portion 620 can apply a force in the direction of compressing the deformable portion 620, and the deformable portion 620, subjected to the force, can be deformed by the operating portion 610.

[0104] The operating section 610 may be formed on one side of the secondary battery 300, extending from the deformable section 620 along the thickness direction of the secondary battery 300. Since the length of the operating section 610 is formed to be longer than the depth of the housing section 110, the operating section 610 may be formed to protrude from the housing section 110. The operating section 610 protruding from the housing section 110 can be grasped and operated by the user.

[0105] The operating part 610 may be made of a rigid material so as not to deform even when gripped and operated by the user. When the user operates the operating part 610 so that one end moves away from the secondary battery 300, it may come into contact with the corner of the inner wall of the housing 110. Since the length of the operating part 610 is longer than the depth of the housing 110, it is supported by the corner of the inner wall of the housing 110 that comes into contact with the operating part 610, and a force can be applied in the direction of compressing the deformable part 620 by the lever principle.

[0106] The operating part 610 may be made of a rigid material so as not to deform even when force is applied, and so as to allow force to be applied to the deformable part 620. However, it is not limited to this, and may be made of plastic, metal, etc. The operating part 610 may be made to be even more rigid than the deformable part 620.

[0107] The deformable portion 620 may be configured such that its shape is changed by the operation of the operating portion 610 in the insert groove 310, thereby separating the secondary battery 300 from the housing portion 110.

[0108] The deformation portion 620 is formed as an extension of the operating portion 610 and may be arranged along the length or width of the secondary battery 300.

[0109] The deformable portion 620 may be positioned so as to be inserted into the insert groove 310. Since the insert groove 310 is formed in the secondary battery 300, even if the secondary battery 300 is placed in the housing portion 110 after the deformable portion 620 has been inserted into the insert groove 310, the problem of the secondary battery 300 being damaged by the thickness of the deformable portion 620 can be prevented.

[0110] The deformable portion 620 receives a compressive force along its length when operated by the operating portion 610. When subjected to this force, at least a portion of the deformable portion 620 deforms into a convex shape toward the secondary battery 300, pushing the secondary battery 300 outward from the housing portion 110 and separating the secondary battery 300 from the housing portion 110.

[0111] The deformable portion 620 may include an elastically deformable material so that it can be elastically deformed by the operation of the operating portion 610. However, it may be made of, for example, plastic or metal.

[0112] The operating section 610 may be formed to be even more rigid than the deformable section 620 so that it can fully apply force to the deformable section 620 without its shape deforming due to user operation.

[0113] The deformable portion 620 may include a fixed portion 621 and an unfixed portion 622.

[0114] The fixed portion 621 may be located at the end of the non-fixed portion 622 and fixed to one side of the housing portion 110. Since the fixed portion 621 is fixed in position on one surface of the secondary battery 300, when the deformation portion 620 is deformed by the operation of the operation portion 610, the deformation portion 620 can be guided to deform into a convex shape toward the secondary battery 300. More specifically, the fixed portion 621 may be bonded to one surface of the insert groove 310 of the secondary battery 300.

[0115] The position of the fixing portion 621 is not limited to this, but for example, it may be formed at one end of the housing portion 110.

[0116] The non-fixed portion 622 is an area that is not fixed to the housing portion 110 and may be formed as an extension in one direction from the fixed portion 621.

[0117] The non-fixed portion 622 is positioned between the fixed portion 621 and the operating portion 610. When the operating portion 610 is operated, the deformable portion 620 receives a compressive force, and the end of the deformable portion 620 is fixed to the housing portion 110 by the fixed portion 621. As a result, the non-fixed portion 622 can be bent into a convex shape toward the secondary battery 300 and its shape can be deformed. The deformed non-fixed portion 622 can push the secondary battery 300 out of the housing portion 110, separating the secondary battery 300 from the housing portion 110.

[0118] Since the non-fixed part 622 is positioned between the secondary battery 300 and the bottom surface of the housing 110, when its shape is deformed, it pushes the secondary battery 300 outward from the bottom of the secondary battery 300 towards the housing 110. This reduces damage to the secondary battery 300 compared to when a structure is installed in the gap between the end of the secondary battery 300 and the housing 110 to separate the secondary battery 300 from the housing 110. Furthermore, the deformable part 620 is positioned between the secondary battery 300 and the bottom surface of the housing 110 and pushes the area near the center of the bottom surface of the secondary battery 300 outward from the housing 110. This prevents the electrode assembly housed inside from being damaged when the secondary battery 300 is separated from the housing 110, as the secondary battery 300 may bend or break.

[0119] Although the present invention has been described above by limited embodiments and drawings, the present invention is not limited thereto, and various implementations are possible by persons with ordinary skill in the art to which the present invention pertains, within the equivalent scope of the technical concept of the present invention and the claims described below.
