As shown in fig. 1 and fig. 2, the present embodiment provides a method for connecting members, which at least includes two connecting members. The two connecting members are a first member 1 and a second member 2 respectively, and a first connecting channel 8 is arranged on the first member 1. The first connecting channel 8 is used for connecting fluid circulation, so that the connecting fluid enters the first connecting channel 8 and is solidified to form the first connecting body 3 connected with the second component 2. When the first member 1 is separated from the second member 2, the relative movement direction between the first member 1 and the second member 2 is a separation direction, and at least a part of the first member 1 blocks the first connecting body 3 at least in one separation direction.
Since the first connecting body 3 can block the first member 1, the first connecting body 3 can hinder the separation of the first member 1 from the second member 2 in the separation direction, increasing the connection strength between the first member 1 and the second member 2 in the separation direction. The connecting fluid is fluid, has flowing capacity, can enter various gaps, is slightly influenced by the shape of the space, can realize the connection between structural members in a complicated and narrow space, and is flexible and convenient to use. Meanwhile, the connecting channel removes partial materials of the first member 1, the structural weight is reduced, and the connecting channel is suitable for products with strict weight control, such as aircrafts.
The connecting fluid may be a bonding gel, such as an epoxy glue. The first member 1 and the second member 2 are bonded to each other by a connecting fluid. Specifically, the adhesive body enters the first connecting channel 8 to form the first connecting body 3, and the first connecting body 3 is bonded to the first member 1 and the second member 2 respectively. Meanwhile, the first connecting body 3 is also mechanically connected with the first member 1, so that the connection strength between the first connecting body 3 and the first member 1 is increased. The connecting fluid can also be a hot-melt plastic, such as a hot-melt adhesive, which can be bonded to the second component 2. Under the general condition, the intensity after the hot melt plastic solidification is higher than the intensity after the connection colloid solidification, is suitable for the higher condition of joint strength, but needs extra heating device to make hot melt plastic melt, has increased equipment cost, and along with the time lapse, hot melt plastic can cool off the solidification gradually moreover, requires to the production rhythm higher. The adhesive colloid is in a semi-fluid state under normal conditions, can be naturally cured, can be manually adjusted in curing time, and is simpler and more convenient in the bonding process.
In this embodiment, when the first member 1 and the second member 2 are connected, the connection fluid is disposed between the first member 1 and the second member 2, and the first member 1 and the second member 2 approach each other and press the connection fluid into the first connection passage 8. The connecting fluid is semi-fluid and has certain fluidity and viscosity. The fluidity or viscosity of the connection fluid may be selected according to the actual conditions, and if the fluidity is too high, the connection fluid easily flows out from the first connection passage 8, and it is difficult to maintain a certain shape and to be cured. If the fluidity is too low, it is difficult to enter the first connecting passage 8.
Depending on the type of the connecting fluid, the connecting fluid may become a rigid body or an elastic body after curing. When the connecting fluid is a rigid body after being solidified, the first member 1 and the second member 2 are rigidly connected, the deformation of the connecting part is small, and the rigidity is high. When the connection fluid is an elastomer after being cured, the first member 1 and the second member 2 are elastically connected through the first connecting body 3, and the first connecting body 3 can absorb vibration between the first member 1 and the second member 2, so that the vibration damping effect is achieved.
As shown in fig. 3 and 4, the second member 2 may be provided with a second connecting passage 11. When the first member 1 is connected to the second member 2, the connection fluid also enters the second connection channel 11 and solidifies to form the second connection body 4 connected to the first connection body 3, and when the first member 1 is separated from the second member 2 in the direction, at least part of the second member 2 also blocks the second connection body 4. In this embodiment, when the first member 1 is connected to the second member 2, the connection fluid enters the first connection channel 8 of the first member 1 and the second connection channel 11 of the second member 2, respectively, and the first connection body 3 and the second connection body 4, which are formed after the connection fluid is solidified, are integrated and connected to each other, the first connection body 3 is connected to the second member 2 through the second connection body 4, and the second connection body 4 is also connected to the first member 1 through the first connection body 3.
When the second connecting channel 11 is disposed on the second member 2, the connecting fluid may be an adhesive glue such as epoxy glue, or a hot-melt plastic such as hot-melt adhesive that can be adhered to the second member 2, or a common hot-melt plastic such as polypropylene. The first connecting body 3 and the second connecting body 4 are mechanically connected to the first member 1 and the second member 2, respectively, and the first member 1 and the second member 2 are mechanically connected to each other through the first connecting body 3 and the second connecting body 4. The common hot melt plastic has wider selection range and can be selected in a subdivided manner according to the requirements of strength, weight and the like.
Specifically, the connecting fluid forms a base 7 between the first member 1 and the second member 2, and the first member 1 and the second member 2 are bonded to each other through the base 7. Specifically, the connection fluid is filled in the gap between the first member 1 and the second member 2, and cured to form the base 7. The base portion 7 increases the bonding area between the first member 1 and the second member 2, and increases the bonding strength between the first member 1 and the second member 2. In this embodiment, the first connecting body 3, the second connecting body 4, and the base portion 7 are all formed by curing the same connecting fluid, the first connecting body 3 is bonded to the second member 2 via the base portion 7, and the second connecting body 4 is bonded to the first member 1 via the base portion 7.
The first connecting channel 8 of the first connecting member and the second connecting channel 11 of the second connecting member 2 may be offset from each other or may correspond to each other. As shown in fig. 3 and 28, when the first connection passage 8 of the first member 1 and the second connection passage 11 of the second member 2 are disposed to correspond to each other, the first connection body 3 and the second connection body 4 are opposed to each other. At this time, when the first member 1 and the second member 2 are separated along the connecting line direction of the first member 1 and the second member 2, the forces applied to the first connecting body 3 and the second connecting body 4 are on the same straight line, and no moment is generated in the direction perpendicular to the separating direction. As shown in fig. 4 and 29, when the first connection path 8 of the first member 1 and the second connection path 11 of the second member 2 are displaced from each other, the first connection body 3 and the second connection body 4 are displaced from each other. At this time, the positions of the connection points between the first member 1 and the second member 2 are more uniform, and when the first member 1 and the second member 2 are separated along the connection line direction of the first member 1 and the second member 2, the force between the first member 1 and the second member 2 is more uniform.
As shown in fig. 1 to 4, the first connecting channel 8 may be linear, or may be curved, tree-shaped, or arc-shaped as shown in fig. 5 to 8, and the linear first connecting channel 8 may be directly formed by machining, which is simple and convenient. The first linking channel 8 of shape need adopt modes such as casting, mould plastics to process and form, but first linking channel 8 internal surface area is bigger, and the structure is more various, is fit for multiple demand.
As shown in fig. 8, the first connecting passage 8 may be a blind hole, and when the first connecting passage 8 is a blind hole, the connecting fluid enters the first connecting passage 8 by flowing, forming the first connecting body 3 according to the shape of the first connecting passage 8. As shown in fig. 1 to 7, the first connecting channel 8 may also be a through hole, when the first connecting channel 8 is a through hole, the connecting fluid may be solidified into the first connecting body 3 in the first connecting channel 8, the first connecting body 3 is formed according to the shape of the body of the first connecting channel 8, and the connecting fluid may enter from one end of the first connecting channel 8 and be extruded from the other end thereof by an extruding manner. After the connection fluid is extruded out, the connection fluid expands at the outlet to form a limiting part 6 coated on the first component 1.
As shown in fig. 9 and 10, the first connecting passage 8 may be a through groove penetrating the first member 1, and the through groove is opened on the surface of the first member 1. When the first member 1 is connected with the second member 2, the connecting fluid is placed on the second member 2, then the surface of the first member 1 provided with the through groove is close to and extrudes the connecting fluid, the connecting fluid fills the through groove and overflows from two ends of the through groove to form two limiting parts 6 respectively.
As shown in fig. 1 to 4, when the first connecting channel 8 is a through hole or a through groove, the first connecting body 3 includes a reinforcing portion 5 and a limiting portion 6 blocking an outer side of at least one end of the first connecting channel 8, the reinforcing portion 5 is inserted into the first connecting channel 8, one end of the reinforcing portion 5 is connected to the limiting portion 6, and the other end of the reinforcing portion 5 is connected to the second member 2. The first connecting channel 8 is linear, and the size of the limiting part 6 is larger than that of the first connecting channel 8 in the direction intersecting the first connecting channel 8. Therefore, the stopper 6 can be caught by the opening of the first connecting passage 8, and the first member 1 can be stopped.
In some embodiments, at least a portion of the first member 1 blocks the first connection body 3 when the first member 1 is separated from the second member 2 in at least three mutually perpendicular directions. Specifically, as shown in fig. 1 to 2, the second member 2 is provided with a second surface for connecting the first connecting body 3, the reinforcing portion 5 is connected to the second surface, the second surface is a plane, and the first connecting passage 8 is linear and perpendicular to the second plane.

The second face is a plane, and the first connecting passage 8 is linear and parallel to the second face.
