Detailed implementation manners

[0024] In the following, in order to make the objectives, features and advantages of the present utility model more obvious and understandable, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0025] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0026] Embodiment 1

[0027] As Figures 1 to 4 shown, this embodiment provides a flexing structure, including: a first docking member 1; a plurality of first flexing components 3 are arranged on the first docking member 1; a second docking member 2; a plurality of flexing holes 5 for the first flexing components 3 to pass through are arranged on the second docking member 2; a second flexing component 4; the second flexing component 4 is arranged on the first docking member 1, and the second flexing component 4 is respectively connected to the first flexing component 3 and the second docking member 2; a locking component 6; one end of the locking component 6 is connected to the first docking member 1, and the other end of the locking component 6 is connected to the second docking member 2.

[0028] In this embodiment, the first docking member 1 is respectively arranged at the outer positions of both ends of the flexing structure. The first docking member 1 is used to connect external devices. The second docking member 2 is arranged between the two first docking members 1 on both sides. The first docking member 1 and the second docking member 2 are connected through the second flexing assembly 4 and the locking assembly 6. The second docking member 2 can be provided with only one or multiple ones. In the case of providing multiple second docking members 2, the multiple second docking members 2 on the inner side are connected through the second flexing assembly 4. A plurality of first flexing assemblies 3 are arranged on the first docking member 1, and a plurality of flexing holes 5 are arranged on the second docking member 2. The first flexing assemblies 3 are correspondingly adapted to the flexing holes 5. The inner diameter of the flexing holes 5 is slightly larger than the outer diameter of the first flexing assemblies 3, so that when the first flexing assemblies 3 are located in the flexing holes 5, there is a certain gap instead of a completely sealed and fitted state. Thus, when the flexing structure works, a slight flexing can occur between the first docking member 1 and the second docking member 2. The second flexing assembly 4 is an elastic structure, which is respectively connected to the first docking member 1 and the second docking member 2. Under the action of the second flexing assembly 4, when the flexing structure works, a slight flexing can occur between the first docking member 1 and the second docking member 2, so that the external devices connected by the two first docking members 1 on both sides can be changed from a static locking state to a small-range flexing state.

[0029] The first docking members 1 on both sides of the flexing structure are respectively connected to the motor output shaft and the load. When the motor works, the work done by the swinging part of its output shaft can be transmitted to the second docking member 2 through the first flexing assembly 3 and the second flexing assembly 4 on the flexing structure, so that the second docking member 2 can receive the kinetic energy of the work done by the output shaft of the motor in the swinging case in addition to the radial work done by the output shaft of the motor, enabling the axial offset and radial offset states on the flexing structure to run in parallel. Thus, it can simultaneously receive the radial work and swinging work of the motor output shaft, and further can withstand high-speed transmission under a large torque state, and can also reduce vibration to reduce the energy loss of transmission.

[0030] Further, the first flexing assembly 3 includes: a first bolt 31 and a round nut 32. The first bolt 31 is arranged on the first docking member 1. One end of the round nut 32 is arranged on the first bolt 31, and the other end of the round nut 32 is connected to the second flexing assembly 4.

[0031] In this embodiment, the first bolt 31 is installed on the first docking member 1, the round nut 32 is arranged on the first bolt 31 and connected to the second flexing assembly 4. The round nut 32 can press the second flexing assembly 4 against the first docking member 1 to complete the connection between the second flexing assembly 4 and the first docking member 1.

[0032] Further, the inner diameter of the flexing hole 5 is larger than the outer diameter of the round nut 32.

[0033] In this embodiment, the position of the deflection hole 5 corresponds to the installation position of the first deflection component 3. The inner diameter of the deflection hole 5 is slightly larger than the outer diameter of the round nut 32, so that there is a certain gap between the round nut 32 and the deflection hole 5, and thus a slight deflection can occur between the deflection hole 5 and the round nut 32.

[0034] Further, the second deflection component 4 includes: a metal gasket 41, a steel wire 42 and a structural adhesive layer 43; the metal gasket 41 is arranged on the first docking member 1, and the metal gasket 41 is connected to the round nut 32; the steel wire 42 is arranged on the metal gasket 41; the structural adhesive layer 43 is coated on the outer side of the metal gasket 41, and the structural adhesive layer 43 is respectively connected to the steel wire 42, the first docking member 1 and the second docking member 2.

[0035] In this embodiment, the length of the steel wire 42 is in a proportional relationship with the overall length of the deflection structure; the metal gasket 41 is pressed by the round nut 32 on the first docking member 1, the steel wire 42 is penetrated through the metal gasket 41, and both ends of the steel wire 42 are respectively located in the cavities of the first docking member 1 and the second docking member 2. The structural adhesive layer 43 is an elastic gel-like structure, and the structural adhesive layer 43 is respectively filled in the cavities of the first docking member 1 and the second docking member 2, and is coated on the outer sides of the steel wire 42 and the metal gasket 41 (see Figure 4 ), an integrated structure is formed among the metal gasket 41, the steel wire 42 and the structural adhesive layer 43, and the above integrated structure is respectively connected to the first docking member 1 and the second docking member 2, so that a slight deflection can occur between the first docking member 1 and the second docking member 2 through this structure.

[0036] Further, a first annular boss 7 for raising the metal gasket 41 is arranged on the first docking member 1; the position of the first annular boss 7 corresponds to the position of the first bolt 31.

[0037] In this embodiment, the first annular boss 7 is arranged on the first docking member 1, its position corresponds to the position of the first bolt 31, the first annular boss 7 can raise the metal gasket 41 to a certain height, so that there is a certain gap space at the docking part between the metal gasket 41 and the surface of the first docking member 1, the structural adhesive layer 43 is filled in the above gap space, so that the structural adhesive layer 43 is coated on the outer side of the metal gasket 41 and is respectively connected to the first docking member 1 and the second docking member 2. The structural adhesive layer 43 is an elastic material, so that a slight swing can occur between the first docking member 1 and the second docking member 2 through elasticity.

[0038] Further, a central hole 81 through which the steel wire 42 can pass and a plurality of first positioning holes 82 through which the first bolts 31 can pass are arranged on the metal gasket 41.

[0039] In this embodiment, the central hole 81 is provided at the central position of the metal gasket 41, and the steel wire 42 passes through the central hole 81 and is disposed at the central position of the metal gasket 41, so that the steel wire 42 can always be kept at the central axis position of the flexing structure; there are two first positioning holes 82, and the two first positioning holes 82 are symmetrically disposed on the opposite two right-angled sides of the metal gasket 41 respectively, and the first bolts 31 at both ends can pass through the above-mentioned first positioning holes 82, thereby positioning the metal gasket 41.

[0040] Further, the metal gasket 41 is a rectangular gasket and / or a circular gasket.

[0041] In this embodiment, the metal gasket 41 can be a rectangular gasket or a circular gasket, and the shape of the metal gasket 41 can be selected according to the actual use requirements of the flexing structure.

[0042] Further, the locking assembly 6 includes: a connecting bolt; the connecting bolt connects the first docking member 1 and the second docking member 2 respectively; a second positioning hole 91 through which the connecting bolt can pass is provided on the metal gasket 41.

[0043] In this embodiment, the locking assembly 6 can adopt a connecting bolt or other connecting structures; a second positioning hole 91 is provided on the metal gasket 41. After the connecting bolt passes through the second positioning hole 91, the two ends are connected to the first docking member 1 and the second docking member 2 respectively, which can simultaneously play the role of connecting the first docking member 1 and the second docking member 2 and positioning the metal gasket 41.

[0044] Further, a second annular boss 92 for lifting the metal gasket 41 is provided on the second docking member 2; the position of the second annular boss 92 corresponds to the position of the second positioning hole 91.

[0045] In this embodiment, the second annular boss 92 is provided on the second docking member 2, which has the same structure as the first annular boss 7 and corresponds to the position of the second positioning hole 91. The second annular boss 92 can lift the metal gasket 41 to a certain height, so that there is a certain gap space at the docking part between the metal gasket 41 and the surface of the second docking member 2, and the structural adhesive layer 43 is filled in the above-mentioned gap space, so that the structural adhesive layer 43 is coated on the outside of the metal gasket 41 and connects the first docking member 1 and the second docking member 2 respectively.
