[0003] [Patent Document 1] JP 2017-039338 A [Patent Document 2] JP 2018-131118 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the vehicle body structure described in Patent Document 1, a vertical plate is used as a reinforcing structure, and the center pillar and the support are The rigidity is improved by adding it to the inside of the idioil. However, the large The vertical plate, which is a non-particulate product, is welded to the center pillar and side sill. It is difficult to dismantle such a structure. In snap-fit ​​connections, it is not easy to remove the tabs to release the fastening. Repeated fastening and unfastening may damage the claws, making fastening impossible.

[0005] The present invention has been made to solve at least part of the above problems, and A joint structure that is easily removable and reusable, and that changes the material properties of the parts to be joined. The object of the present invention is to provide a bonded structure that does not [Means for solving the problem]

[0006] The present invention has been made to solve at least part of the above problems, and provides the following: It can be realized in the form.

[0007] (1) According to one aspect of the present invention, there is provided a joint structure for joining a first member and a second member. The joint structure includes a first fixing portion fixed to the first member and a second fixing portion fixed to the second member. a second fixed portion fixed to the first fixed portion and a second fixed portion connected to the first fixed portion and the second fixed portion, respectively, a first direction connecting the first fixing portion and the second fixing portion, the first direction connecting the first fixing portion and the second fixing portion being formed of a connecting elastic body. The distance between the first fixing portion and the second fixing portion is changed by expanding and contracting due to elastic deformation along the direction. a connecting elastic body that can be stretched in a second direction that intersects with the first direction; By doing so, the reinforcement restricts the expansion and contraction caused by the elastic deformation of the connecting elastic body along the first direction. A structure.

[0008] According to this configuration, the first fixing member is fixed to the first fixing member while the connecting elastic body is elastically deformable along the first direction. The first fixing portion is fixed to the first member, and the second fixing portion is fixed to the second member, and then the reinforcing structure is The reinforcing structure is attached to the connecting elastic body, and restricts elastic deformation of the connecting elastic body in the first direction. The tension in response to the expansion and contraction of the connecting elastic body acts as a force to fix the first member and the second member. When releasing the first and second members from each other, the same procedure is carried out in the opposite direction to that used for fastening. In other words, after the reinforcing structure is removed from the connecting elastic body, the connecting elastic body is moved in a first direction. By stretching the fixing portion along the fixing portion, the fixing of the first fixing portion and the second fixing portion can be released. It is easy to remove the reinforcing structure from the connecting elastic body and release the first fixing part and the second fixing part. The first member and the second member can be repeatedly fixed and released by the operation. By using this configuration, the first member and the second member can be connected in a removable and reusable manner. In addition, the first member and the second member can be fixed and released by the first method. The material properties of the components being joined, such as damage or heating of the first component and the second component, are not changed. It is possible to connect multiple members. Furthermore, this configuration allows the joining structure to be added from the outside of the members to be joined. This allows easy repairs and upgrades by replacing parts. By making it easier to replace parts, it is possible to plan and collaborate on small-lot, multi-product production. It becomes possible to set the common module area.

[0009] (2) In the connection structure of the above aspect, the connection elastic body has a ring shape, The first fixing portion and the second fixing portion are disposed at positions facing each other via the connecting elastic body. In this case, the first direction and the second direction may be perpendicular to each other. According to this configuration, the first fixing portion and the second fixing portion are disposed at opposing positions in the ring shape. Therefore, the connecting elastic body expands and contracts along the first direction connecting the first fixing portion and the second fixing portion. In this manner, the first member and the second member are fixed to and released from each other. Compared to a case where the fixed portion and the second fixed portion are arranged at positions not facing each other in the ring shape, When the deformation occurs along the direction of 1, the elongation is maximized, and when the first member and the second member are fixed, Therefore, the tension of the connecting structure between the first member and the second member is maximized. In addition, since the amount of elongation of the connecting elastic body in the first direction is maximized, the first This makes it easy to fasten and release the member to the second member.

[0010] (3) In the joint structure of the above aspect, the reinforcing structure is detachably attached to the connecting elastic body. The connecting elastic body is a rigid body, and is attached to the inside of the ring shape of the connecting elastic body. The expansion and contraction due to elastic deformation along the first direction may be restricted. According to this configuration, the reinforcing structure is attached to the inside of the ring-shaped connecting elastic body and is elastically deformable. Since the reinforcing structure is a rigid body, all of the parts that are in contact with the connecting elastic body are connected. The elastic deformation of the connecting elastic body is restricted. For this reason, for example, a part of the reinforcing structure is fixed. The method applies a restricting force to the entire connecting elastic body rather than to a part of the fixed connecting elastic body. As a result, damage to the connecting elastic body can be suppressed, and the connecting structure It can extend the lifespan of the body and increase the number of times it can be reused.

[0011] (4) In the combined structure of the above aspect, the reinforcing structure is a first reinforcing part removably fixed to one of the members; and a first reinforcing part removably fixed to the first member and the second member. and a second reinforcing part removably fixed to one of the first and second members. The reinforcing portions are connected to the connecting elastic bodies and face each other via the connecting elastic bodies, Furthermore, a line connecting the first reinforcing portion and the second reinforcing portion is disposed in a position along the second direction. The first reinforcing portion and the second reinforcing portion are disposed between the first member and the second member. By being fixed to one side, the elastic deformation of the connecting elastic body along the first direction causes the elastic body to expand and contract. may be regulated. According to this configuration, the ring-shaped elastic connection body is stretched in a second direction different from the first direction, By fixing the first reinforcing portion and the second reinforcing portion, the elongation of the connecting elastic body in the first direction is restricted. As a result, the tension, which is the ring-shaped contraction force of the connecting elastic body, is applied to the first member and the second member. It acts as a fixing force between the material.

[0012] (5) In the bonded structure of the above aspect, the reinforcement structure includes a plurality of annular elastic bodies. The electrodes may be arranged side by side on a plane including the first direction and the second direction. According to this configuration, instead of one large ring-shaped connecting elastic body, multiple ring-shaped elastic bodies are used. Therefore, a single elastic connection body is formed. A plurality of annular elastic bodies having the same shape are combined according to the purpose without manufacturing the body and the reinforcing structure. This allows the production of a connecting elastic body and a reinforcing structure with a reduced manufacturing cost. This allows for easy fabrication of bonded structures.

[0013] (6) According to another aspect of the present invention, there is provided a joint structure for joining a first member and a second member. A design system is provided, the design system including a first fixed member fixed to the first member. a second fixing portion fixed to the second member; and a second fixing portion fixed to the first fixing portion and the second fixing portion. a connecting elastic body formed of an elastic member and connected to the first fixing portion and the second fixing portion, The first fixing portion and the second fixing portion are elastically deformed in a first direction along which the fixing portions are joined, and the elastic deformation causes the first fixing portion and the second fixing portion to expand and contract. A connecting elastic body capable of changing the distance between the connecting elastic body and the fixing part, an input part for inputting the shape of each of the connecting elastic body and the fixing part, and By using the input value input to the input unit, a pre-setting is performed when the first member and the second member are joined. A tension to be applied along the first direction is applied to the connecting member in a second direction intersecting the first direction. A force for stretching the elastic body in the second direction is calculated using the force for stretching the elastic body in the second direction. and a design section that designs the shape of the reinforcement structure optimized for the purpose. According to this configuration, the user can easily install a reinforcing structure for connecting the first member and the second member. The shape can be easily designed.

[0014] The present invention can be realized in various aspects, for example, a coupling structure, a fixing structure, Member, joint structure design device, structure joint method, fixing method, joint structure design method, and and systems that include these devices or that implement these methods, and and a server device for distributing the computer program.

The elastic deformation along the Z-axis direction (first direction) connecting the fixed portion 16 and the second fixed portion 17 causes the Therefore, the distance between the first fixing portion 16 and the second fixing portion 17 can be changed, and therefore, as shown in FIG. As shown, the connecting elastic body 14 extends in the negative Z-axis direction.

[0030] In FIG. 8, in addition to the first fixing portion 16 of the connecting member 10, a second fixing portion 17 is fixed to the second member 30.

Thereafter, the reinforcing member 11 is attached to the connecting elastic body 14, The elastic deformation of the connecting elastic body 14 in the Z-axis direction is restricted by the reinforcing member 11. The tension according to the expansion and contraction of the first member 20 and the second member 30 functions as a force for fixing the first member 20 and the second member 30 together. When the first member 20 and the second member 30 are to be released from the fixed state, the procedure is reversed, that is, After removing the reinforcing member 11 from the connecting elastic body 14, the connecting elastic body 14 is By stretching the wire, the first fixing portion 16 and the second fixing portion 17 are released. In this embodiment, the reinforcing member 11 is removed from the connecting elastic body 14, and the first fixing portion 16 and the second fixing portion 17 are The first member 20 and the second member 30 can be fixed and released by the simple operation of releasing the fixing portion 17.

In addition, the first member 20 and the second member 30 can be fixed and In the release, the first member 20 and the second member 30 may be damaged or the materials of the members to be joined may be damaged due to heating or the like. It is possible to bond a plurality of members without changing their characteristics. Since the connecting member 10 can be added from the outside of the material, repairs and upgrades can be easily performed by replacing parts of the material. By making it easier to replace parts, it is possible to produce a wide variety of products in small quantities. This will enable collective planning and the establishment of common module areas across industries.

The connecting elastic body 14 expands and contracts along the Z-axis direction connecting the first fixing portion 16 and the second fixing portion 17. In this manner, the first member 20 and the second member 30 are fixed to and released from each other. When the first fixing portion 16 and the second fixing portion 17 are arranged in positions not facing each other in the ring shape, In comparison, the elongation margin during deformation along the Z-axis direction is maximized, and the first member 20 and the second member Therefore, the tension when the connecting member 10 is fixed to the first member 20 and the second member 30 is maximum. 30. Also, the amount of elongation of the connecting elastic body 14 in the Z-axis direction can be maximized. Since the distance between the first member 20 and the second member 30 is maximized, the first member 20 and the second member 30 can be easily fixed and released.

[0035] In addition, by attaching the elastic member 14 to the inside of the ring-shaped elastic member 14, the elastic deformation of the elastic member 14 can be prevented. The reinforcing member 11 of the present embodiment is a rigid body, so the connecting elastic body 1 The elastic deformation of the connection elastic body 14 is restricted at all parts in contact with the connecting elastic body 14. A part of the reinforcing member 11 is fixed to a part of the fixed connecting elastic body 14 by a method such as fixing. Rather than applying a restricting force, a regulating force is applied to the entire connecting elastic body 14 in a well-balanced manner. As a result, damage to the elastic connection body 14 can be suppressed, the life of the structure 100 can be extended, and the number of times of reuse can be increased. can be improved.

The front surface 31a of the member 30a includes a flat portion 31F and a claw portion 31G. , a groove portion 31G1 extending from a flat portion 31F parallel to the ZX plane toward the Y-axis positive direction, and a groove portion 31G 1 and extending in the positive direction of the X-axis. As shown in FIG. 12, the groove portion 31G1 is aligned along the X axis by the return portion 31G1 and the return portion 31G2. A groove shape recessed in the negative direction is formed.

[0039] The first reinforcing portion 11A is formed in a part of the connecting elastic body 14a, and as shown in FIG. The first reinforcing portion 1 forms an elastically deformable portion that is thicker than the elastic body 14a and has a circular cross section. The diameter of the cross section of the connecting elastic body 14a on which the elastic member 1A is arranged is equal to the diameter of the flat portion 31F of the second member 30a. The distance is slightly smaller than the distance to the bottom portion 31G2.

[0040] As shown in FIG. 10, the second member 30a of the second embodiment has a claw on the front surface 31a. At a position opposite to the portion 31G, a claw portion 31GG having the same shape is formed. The position of the second engagement portion 36H1 formed on the engagement surface 36 is the same as that of the second engagement portion 36H1 formed on the engagement surface 36. The position is symmetrical to the claw portion 31G with respect to the YZ plane passing through the center of gravity. In the elastic connection body 14a, the first reinforcing portion 11A is disposed at a position opposite the position of the elastic connection body 14a. The second reinforcing portion 11B is formed at a position where the second reinforcing portion 11B is formed. This is a position that is axisymmetric with respect to the first reinforcing portion 11A across the YZ plane that passes through the center of gravity of the elastic body 14a.

[0041] As described above, the first reinforcing portion 11A and the second reinforcing portion 11B are respectively connected to the connecting elastic body 14a. The first reinforcing portion 11A and the second reinforcing portion 11B are connected to each other and face each other via the connecting elastic body 14a. The line connecting the second reinforcing portion 11B is disposed in a position along the X-axis direction (second direction).

By fixing the connecting elastic body 14a to the portion 31GG, the extension of the connecting elastic body 14a in the Z-axis direction is restricted. As a result, the tension, which is the force that causes the ring-shaped connecting elastic body 14a to contract, is applied to the first member 20 and the second member 3. It acts as a force that fixes 0a.

[0042] <Third embodiment> 13 and 14 are schematic front views of a connection elastic body 14b according to the third embodiment. FIG. 14 shows a third embodiment of the connecting member, excluding the reinforcing member, a connecting elastic body 14b, a first The third embodiment has a fixing portion 16 and a second fixing portion 17. In comparison, the connecting elastic body 14b is an annular member (annular elastic body) 14R which is made up of two annular elastic bodies. The shape of the reinforcing member is adapted to the annular members 14R and 14R2. Therefore, the third embodiment differs from the first embodiment in the following points: The description will be given below, and the description of the same shapes and the like as in the first embodiment will be omitted.

[0043] FIG. 13 shows a state in which the elastic deformation of the connecting elastic body 14b is not restricted. As shown in FIG. 13, the connecting elastic body 14b is disposed on the lower end side of the first fixing portion 16 in the negative Z-axis direction. The annular member 14R1 is connected to the Z-axis positive side, and the other end of the annular member 14R1 is connected to the Z-axis positive side. The other end, which is the negative Z-axis direction side, is connected to the upper end side of the second fixed portion 17, which is the positive Z-axis direction side. and a connecting annular member 14R2.

[0044] The annular members 14R1 and 14R2 have the same shape and are made of a stretchable material such as resin. The annular members 14R1 and 14R2 are shaped such that their elastic deformation is restricted by the reinforcing members. When the first fixing portion 16 and the second fixing portion 17 are not fixed to each other, the Z-axis direction intersects with the Z-axis direction. The annular members 14R1 and 14R2 are ellipses with their major axis in the X-axis direction. In other words, they are arranged side by side on the ZX plane including the X-axis direction and the Z-axis direction. The reinforcing member of the third embodiment, which is not elastically deformable, is similar to the reinforcing member 11 of the first embodiment.

[0045] FIG. 14 shows the state in which the fixing portion 16 is extended along the Z-axis direction connecting the first fixing portion 16 and the second fixing portion 17. As shown in FIG. 14, the reinforcing member prevents elastic deformation. The unrestricted annular members 14R1 and 14R2 extend in a predetermined direction, such as the Z-axis direction. When the shape of the annular members 14R1 and 14R2 changes and they extend along the Z-axis direction, The distance between the first fixing portion 16 and the second fixing portion 17 in the Z-axis direction becomes large. As in the first embodiment of the joining member 10, the connecting elastic body 14b connects the first member 20 and the second member 30. After the annular members 14R1 and 14R2 are fixed, the elastic deformation of each of the annular members 14R1 and 14R2 is restricted by the reinforcing member. As a result, the first member 20 and the second member 30 are pulled apart by the tension of the annular members 14R1 and 14R2. It is fixed.

[0046] As described above, in the third embodiment, the annular members 14R1 and 14R2 are In other words, in the third embodiment, the first embodiment is similar to the first embodiment.

Therefore, a specific shape can be formed according to the application. Without manufacturing the connecting elastic body and the reinforcing member having the same shape, a plurality of annular members 14R1, 14R2 and a reinforcing member to be attached to the annular members 14R1 and 14R2 are assembled according to the purpose. This allows the manufacturing cost of the connecting member to be reduced, The connecting member can be easily manufactured.
