[0034] Reference Figures 1 to 3 According to a first aspect of the present invention, the anti-deformation mounting shell includes a bottom shell 100, which is a stamped part. The bottom shell 100 has a bottom plate 110 and at least two side edges 120. The side edges 120 are arranged along the edge of the bottom plate 110. All the side edges 120 and the bottom plate 110 enclose a mounting cavity 100a with an opening. The ends of two adjacent side edges 120 that are close to each other are respectively provided with a slot 121 and a snap-fit ​​part 122. The snap-fit ​​part 122 is snapped into the corresponding slot 121.

[0035] The anti-deformation mounting shell provided by this utility model has a bottom shell 100 that is a stamped part. The two adjacent sides 120 of the bottom shell 100 can be engaged with each other through the engagement part 122 and the slot 121, so that the two adjacent sides 120 can support each other to resist deformation, thereby improving the deformation resistance of the sides 120. When this anti-deformation mounting shell is applied to clutch devices and locks, it can effectively reduce the degree of deformation of the sides 120 of the bottom shell 100 when encountering strong door opening and closing, and avoid the situation where the side 120 is severely deformed, causing the clutch device to malfunction.

[0036] Reference Figure 1 and Figure 5 According to some embodiments of the present invention, four sides 120 are provided and arranged in a rectangular shape, so that each side 120 is engaged with the other two adjacent sides 120 through the engaging part 122 and the engaging slot 121, so that each side 120 is supported by the other two adjacent sides 120.

[0037] It should be noted that the bottom shell 100 can be configured in other shapes besides a rectangle. For example, the bottom plate 110 can be shaped like a shave, in which case all four sides 120 of the bottom plate 110 can be provided with side edges 120. Of course, three of the four sides 120 of the bottom plate 110 can be provided with side edges 120, and the other side can be left unprovided. In some other embodiments, the bottom plate 110 can also be configured as a triangle, thereby at least two of the three sides 120 of the bottom plate 110 can be provided with side edges 120.

[0038] Reference Figures 2 to 4 According to some embodiments of this utility model, the snap-fit ​​portion 122 has a first surface 1221, a second surface 1222, and a third surface 1223. The first surface 1221 is used to abut against the bottom wall of the slot 121, the second surface 1222 is used to abut against the inner wall of the slot 121 near the bottom shell 100, and the third surface 1223 is used to abut against the inner wall of the slot 121 away from the bottom shell 100. Thus, the snap-fit ​​portion 122 and the side wall or bottom wall of the slot 121 abut against each other through surface mating, which can form a better supporting effect and a better resistance to deformation.

[0039] Reference Figures 2 to 4 According to some embodiments of the present invention, the portion of the third surface 1223 near the top of the snap-fit ​​part 122 is a slope or an arc surface, which serves as a transition and avoidance function. This can reduce the interference between the snap-fit ​​part 122 and the side wall of the slot 121 during the stamping process of the bottom shell 100, so that the snap-fit ​​part 122 can be smoothly snapped into the slot 121.

[0040] Reference Figure 1 and Figure 5 According to some embodiments of the present invention, the anti-deformation mounting shell further includes a cover plate 200, which covers the opening of the mounting cavity 100a and abuts against at least a portion of the side 120. Thus, the cover plate 200 closes the opening of the mounting cavity 100a, and the side 120 of the bottom shell 100 can support the cover plate 200.

[0041] Reference Figure 1 and Figure 5 According to some embodiments of the present invention, a positioning structure is provided between the cover plate 200 and the side 120 to position the cover plate 200.

[0042] Reference Figure 1 and Figure 5 In the specific implementation process, the positioning structure includes a positioning protrusion 123 and a positioning groove 210. The positioning protrusion 123 can be set on the side 120, the positioning groove 210 is set on the cover plate 200, and the positioning protrusion 123 is engaged with the cover plate 200.

[0043] In other embodiments, the positioning structure may also adopt other configuration methods. For example, the positioning structure includes a folded edge disposed on the cover plate 200, which is inserted into the mounting cavity 100a and abuts against the corresponding side 120, thereby achieving the positioning of the cover plate 200.

[0044] Reference Figure 1 , Figure 5 , Figure 6 According to some embodiments of this utility model, at least a portion of the side 120 protrudes into the mounting cavity 100a and is provided with a mounting part 124. The mounting part 124 has bolt mounting holes 1241, and the base plate 110 has positioning post clearance holes 111. All positioning post clearance holes 111 correspond one-to-one with all bolt mounting holes 1241. In specific implementation, the lock body or the lock panel of the lock is provided with positioning posts. The positioning posts pass through the positioning post clearance holes 111 and are opposite to the corresponding bolt mounting holes 1241. Thus, locking bolts can be installed in the bolt mounting holes 1241. The locking bolts are screwed to the positioning posts, thereby fixing the base shell 100 to the lock body or the panel.

[0045] It is conceivable that in other embodiments, the anti-deformation mounting shell can also be fixed to the lock body or panel in other ways. For example, the bolt mounting hole 1241 mentioned above is provided on the cover plate 200. In this case, the side 120 does not need to be provided with the mounting part 124 mentioned above. The locking bolt can connect and fix the cover plate 200 to the positioning post, thereby realizing the fixing of the mounting shell.

[0046] Typically, a return torsion spring 500 is provided between the clutch assembly 300 and the base housing 100 of the clutch device. In the prior art, a torsion spring positioning part 125 is usually stamped out from the base plate 110 into the mounting cavity 100a from a portion of the base plate 110 and a portion of the side 120. However, in this existing arrangement, notches are formed on both sides of the torsion spring positioning part 125 in the base plate 110, a large portion of the base plate 110 is cut off, and the torsion spring positioning part 125 is completely separated from the side 120. The side 120 has a notch at the stamping position of the torsion spring positioning part 125, resulting in insufficient strength of the base plate 110 at the torsion spring positioning part 125.

[0047] Reference Figures 5 to 7According to some embodiments of the present invention, two opposite sides 120 are stamped with torsion spring positioning parts 125 into the mounting cavity 100a, and the torsion spring positioning parts 125 abut against the base plate 110. The foot of the clutch assembly's reset torsion spring 500 can abut against the torsion spring positioning part 125. After the door handle drives the clutch assembly 300 to rotate, the reset torsion spring 500 can drive the clutch assembly 300 to rotate and reset. Since the torsion spring positioning part 125 abuts against the base plate 110, the frictional resistance between the torsion spring positioning part 125 and the base plate 110 can be used to improve the ability of the torsion spring positioning part 125 to withstand the pressure of the torsion spring 500. At the same time, since the torsion spring positioning part 125 is punched out from the side 120 and abuts against the base plate 110, the amount of the base plate 110 that is cut off can be reduced, and the side 120 can support the base plate 110 through the torsion spring positioning part 125, thereby enhancing the deformation resistance of the base plate 110 at the torsion spring positioning part 125.

[0048] Reference Figures 5 to 7 According to some embodiments of the present invention, the end of the torsion spring positioning part 125 near the base plate 110 and the end away from the base plate 110 are separated from the corresponding side 120. At this time, since the torsion spring positioning part 125 is stamped out from the side 120, at least one end of the other two ends of the torsion spring positioning part 125 is connected to the side 120. Therefore, the torsion spring positioning part 125 can be obtained by simply stamping the side 120 along the base plate 110 into the mounting cavity 100a. The processing is simple and convenient.

[0049] Reference Figure 1 and Figure 5 According to a second aspect embodiment of the present invention, a clutch device includes the aforementioned anti-deformation mounting shell. Applying the aforementioned anti-deformation mounting shell to the clutch device improves the deformation resistance of the side 120 of the base shell 100, thereby effectively reducing the degree of deformation of the side 120 of the base shell 100 when encountering a forceful door opening or closing. The clutch assembly 300 and the electric actuator 400 of the clutch device are disposed within the mounting cavity 100a. The specific arrangement of the clutch assembly 300 and the electric actuator 400 is mature technology in the art and will not be described in detail here.

[0050] A lock according to a third aspect of the present invention includes the aforementioned clutch device. Applying the clutch device to the lock can effectively reduce the deformation of the side 120 of the bottom shell 100 when encountering a forceful door opening or closing.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
