The common method is to pour liquid glue into the entire motor cavity, but this method requires a large amount of silicone rubber, and during the installation process, other components need to be protected, resulting in low installation efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, one of the purposes of the present application is to provide a material-saving tooling, which has the advantages of reducing the amount of organic silica gel used and improving installation efficiency.

[0006] By adopting the above technical solution, the accommodating cavity formed by the body and the stator accommodates the medium, so that the medium does not need to be poured into the entire motor chamber, saving the medium usage and eliminating the need to protect other components during the installation process, thereby improving the installation efficiency.

[0007] In a preferred example, the present application can be further configured as follows: a seal is provided between the base plate and the bottom of the stator, and the seal is used to prevent leakage of the medium.

[0009] In a preferred example, the present application can be further configured as follows: a plurality of protrusions are provided on the inner core.

[0010] By adopting the above technical solution, the presence of the protrusions results in a gap after the medium is formed. The formed medium is easily deformed due to thermal expansion and contraction, and the gap reserves space for the deformation of the medium.

[0011] In a preferred example, the present application can be further configured as follows: the protrusions are evenly and symmetrically distributed along the inner core.

[0012] By adopting the above technical solution, the volume of the medium after thermal expansion can be evenly distributed to the notch.

[0013] In a preferred example, the present application can be further configured as follows: a supporting portion is also provided on the inner core, and the supporting portion is used to support the inner core.

[0014] By adopting the above technical solution, the impact force exerted by the medium on the inner core can be prevented from causing deformation of the inner core.

[0015] In a preferred example, the present application can be further configured as follows: the support portion includes a support column and a support plate, the support plate is used to transfer the force applied by the inner core to the support column, and the support column is used to support the support plate.

[0016] By adopting the above technical solution, the support plate transmits the force applied by the inner core to the pillars, and the pillars support the support plate, which saves more materials when processing the main body while meeting the support requirements.

[0017] In a preferred example, the present application can be further configured as follows: the body includes a limiting groove, the limiting groove is used to limit the position of the stator on the body, and the limiting groove is also used to accommodate a seal.

[0018] By adopting the above technical solution, the position of the stator on the body is stabilized and not easily offset, and the sealing member is not easily dropped.

[0019] In a preferred example, the present application can be further configured as follows: the support plate is provided with an inclined surface, and the inclined surface is used to increase the contact area between the support plate and the inner core.

[0020] By adopting the above technical solution, the inclined surface increases the contact area between the support plate and the inner core, so that the supporting force of the support pillar on the support plate is evenly distributed to the inner core.

[0021] In a preferred example, the present application may be further configured as follows: the sealing member includes a groove, and the groove is used to define the relative position of the sealing member and the stator.

[0022] By adopting the above technical solution, the groove defines the relative position of the seal and the stator, so that the stator is not easily deviated on the seal. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present application is further described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figure 1 and Figure 3 , is a material-saving tool disclosed in the present application, including a body 1, a stator 2 including an outer shell, the body 1 and the outer shell cooperate to form a accommodating chamber 3, the accommodating chamber 3 is used to accommodate a medium, the body 1 includes an inner core 4, a bottom plate 5 and a limiting groove 9, the bottom plate 5 is used to contact the bottom of the stator 2, a seal 6 is arranged between the bottom plate 5 and the bottom of the stator 2, the seal 6 is used to prevent leakage of the medium, the seal 6 includes a groove 61, the groove 61 is used to limit the relative position of the seal 6 and the stator 2, the limiting groove 9 is used to limit the position of the stator 2 on the body 1, and the limiting groove 9 is also used to accommodate the seal 6. In this embodiment, the medium can be organic silicone, and the seal 6 is annular and made of rubber.

[0029] The inner core 4 is located on the bottom plate 5. The inner core 4 is used to support the medium. A support portion 8 and a plurality of protrusions 7 are provided on the inner core 4. The protrusions 7 are evenly and symmetrically distributed along the inner core 4. The support portion 8 is used to support the inner core 4. The support portion 8 includes a support column and a support plate 82. The support column 81 is used to support the support plate 82. The support plate 82 is used to transfer the force applied by the inner core 4 to the support column 81. The support plate 82 is provided with an inclined surface 83. The inclined surface 83 is used to increase the contact area between the support plate 82 and the inner core 4. In the present embodiment, the number of protrusions 7 is set to eight groups, and the number of support plates 82 is set to six groups. In other embodiments, the number of protrusions 7 and support plates 82 can be set as needed.

[0030] When the main body 1 and the stator 2 are connected, the seal 6 is first placed in the limiting groove 9, and then the stator 2 is extended into the limiting groove 9, so that the connection between the bottom of the stator 2 and the bottom plate 5 is not prone to leakage. After the connection is completed, the medium is poured into the accommodating cavity 3, and the support part 8 provides support for the inner core 4, so that the inner core 4 is not easily deformed under the impact of the medium, thereby making the solid medium not easily deformed. After the medium forms a solid state, the main body 1 and the seal 6 are removed, and a gap is formed at the position of the protrusion 7 after the main body 1 leaves.

[0031] The implementation principle of this embodiment is as follows: the accommodating cavity 3 formed by the body 1 and the stator 2 is used to accommodate the medium, so that the medium does not need to be poured into the entire motor chamber, saving the amount of medium. The inner core 4 isolates the medium and other components, so that other components do not need to be protected during the installation process, thereby improving the installation efficiency. A protrusion 7 is provided on the inner core 4. The existence of the protrusion 7 causes a gap to exist in the medium after molding. The molded medium is easily deformed due to thermal expansion and contraction. The gap reserves space for the deformation of the medium, thereby making the internal stress in the cavity due to the thermal expansion of the medium smaller.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
