The driving part 13 is transmission-connected to the inner ring of the cylindrical barrel 7, and the inner ring of the cylindrical barrel 7 simultaneously supports the driving part 13 as a first supporting end 14. The side of the cylindrical shell 10 away from the output shaft 12 extends toward the outer side of the cylindrical barrel 7 and is connected to the first bracket 4 or the second bracket 5. The side of the cylindrical shell 10 away from the output shaft 12 serves as a second supporting end 15, which is supported by the first bracket 4 or the second bracket 5. The cylindrical shell 10 and the electric motor 3 are suspended and supported in the cylindrical barrel 7 by the first supporting end 14 and the second supporting end 15.

[0036] The electric motor 3 is provided with a reduction box 33 on one side of the output shaft 12. The power of the electric motor 3 is decelerated by the reduction box 33 and then outputted from the output shaft 12. The reduction box 33 is, for example, a gear reduction box, preferably a planetary gear reduction box. Fig.11 The planetary gears and other structures of the reduction box 33 are not drawn, but this does not hinder the understanding of the technical solution.

[0037] In some embodiments, Fig.11 As shown, the first bracket 4 is provided with a plug-in column 28, and the first end portion 8 is provided with a sleeve 29. The plug-in column 28 is axially plugged with the sleeve 29. The inner hole of the sleeve 29 is a polygonal plug-in hole 27, and the plug-in column 28 is a corresponding polygonal column. The plug-in column 28 realizes a rotatable connection between the first end portion 8 and the first bracket 4 through the sleeve 29. Of course, the sleeve 29 can be replaced with other types of bearings.

[0038] In some embodiments, Fig.11As shown, the second bracket 5 is provided with a limit seat 30, the second end 9 is provided with a sleeve 29, the limit seat 30 is also provided with a polygonal plug hole 27, the second support end 15 is axially plugged with the plug hole 27 to support and fix the second support end 15, and the sleeve 29 of the second end 9 is sleeved on the second support end 15, the second bracket 5 indirectly realizes the rotatable connection between the second end 9 and the second bracket 5 through the limit seat 30, the second support end 15, and the sleeve 29. Of course, the sleeve 29 can be replaced with other types of bearings. After such a design, the support problem of the second support end 15 is solved, and the technical problem of the rotatable connection between the second end 9 and the second bracket 5 is also solved. The structure is compact. In addition, it also solves the problem of how to conveniently install the drive assembly formed by connecting the columnar cover 10, the electric motor 3 and the drive unit 13 in the columnar barrel 7.

[0039] Further, such as Figure 4 , 5 As shown in FIG. 6 , a connecting structure 23 is provided in the inner circle of the cylindrical barrel 7, and the cylindrical housing 10, the electric motor 3 and the driving part 13 are connected to form a driving assembly, and the driving assembly is inserted and sleeved into the cylindrical barrel 7 from the second end 9 of the cylindrical barrel 7, and the connecting structure 23 and the driving part 13 are connected in transmission through the insertion sleeve, and the connecting structure 23 serves as the first supporting end 14. In this way, it is more convenient to produce.

[0040] The second end portion 9 can be installed after the drive assembly is inserted and sleeved in the cylindrical barrel 7. In this way, the diameter of the inner hole of the second end portion 9 can be made smaller, and there is no need to enlarge the inner hole of the second end portion 9 for the drive assembly to be inserted and sleeved, which is beneficial for blocking noise in the axial direction.

[0041] like Figure 5 As shown, the connection structure 23 can be set as a circumferentially arranged transmission tooth, and correspondingly, the driving part 13 is provided with a matching circumferential protrusion. Of course, the connection structure 23 can also be other structures, such as a spline transmission structure, a polygonal transmission structure, a sleeve tight-fitting transmission structure, etc.

[0042] In some embodiments, Figure 6 , 7 As shown, the cylindrical housing 10 includes a first sleeve portion 16 and a second sleeve portion 17. The first sleeve portion 16 is sleeved from the side where the output shaft 12 of the electric motor 3 is located, and the second sleeve portion 17 is sleeved from the side of the electric motor 3 away from the output shaft 12. The first sleeve portion 16 and the second sleeve portion 17 are sleeved and connected relative to each other. This facilitates assembly. In this example, a buckle structure is further adopted, so that the first sleeve portion 16 and the second sleeve portion 17 are sleeved and connected relative to each other more efficiently and conveniently.

[0043] In some embodiments, Figure 6 ,7 As shown in FIG. 8 , a circumferential limit protrusion 18 is provided on one side of the output shaft 12 of the electric motor 3, and a matching hole 19 is provided on the first sleeve portion 16 to be axially sleeved with the circumferential limit protrusion 18, and the matching hole 19 limits the circumferential rotation of the electric motor 3 relative to the cylindrical housing 10. In this way, the circumferential limit setting is convenient.

[0044] In this example, if Fig.11 As shown, the circumferential limit protrusion 18 is arranged on the end cover 31, and the end cover 31 is fixed to the end where the output shaft 12 of the electric motor 3 is located by screws 32. When the end cover 31 is axially installed, the circumferential ring portion of the first shock absorber seat 20 is axially pressed and fitted on the end face of the first sleeve portion 16 at the same time.

[0045] In some embodiments, Figure 8 , 11 As shown, a first shock absorbing seat 20 is sleeved on the side where the output shaft 12 of the electric motor 3 is located, and a second shock absorbing seat 21 is sleeved on the side of the electric motor 3 away from the output shaft 12. The electric motor 3 is suspended and supported in the columnar housing 10 through the first shock absorbing seat 20 and the second shock absorbing seat 21. In this way, the structure is simple and compact, and the production and manufacturing are convenient. In addition, it is beneficial for most of the main body of the electric motor 3 to be suspended in the columnar housing 10.

[0046] In some embodiments, Figure 5 , 11 As shown, the inner ring of the cylindrical body 7 is provided with a partition 22, which divides the cylindrical body 7 into two chambers, one of which is equipped with the cylindrical housing 10, and the inner ring of the cylindrical body 7 near the partition 22 is provided with a connecting structure 23, which is connected to the driving part 13; the second shock-absorbing seat 21 is set as a bowl-shaped structure, the opening side of which is used to be sleeved with the electric motor 3, and the bottom of the bowl-shaped structure, the partition 22 and the first shock-absorbing seat 20 located on one side of the partition 22 together form a multi-layer isolation structure along the axial direction. In this way, on the one hand, it is beneficial to reduce vibration and noise, and on the other hand, the partition 22 is beneficial to increase strength and ensure the transmission stability of the cylindrical body 7.

[0047] In some embodiments, Figure 5 , 11 As shown, the connecting structure 23 is arranged in the middle or near the middle. In this way, the transmission effect is better.

[0048] In some embodiments, Figure 1 , 2As shown in Figures 11, 13, 14, and 15, the first end 8 and the second end 9 of the columnar barrel 7 are respectively provided with a first gear 24 and a second gear 25 in the circumference thereof, and the cover plate 2 is correspondingly provided with a first rack 26 and a second rack. The first gear 24 is meshed with the first rack 26 for transmission, and the second gear 25 is meshed with the second rack for transmission. In this way, not only is the transmission reliable and the transmission force is large enough, but it is also conducive to the opening and closing of the cover plate 2 with good position accuracy. In addition, it is conducive to simplifying the manufacturing, that is, there is no need to form a corresponding structure on the columnar barrel 7, and the first gear 24 and the second gear 25 can be formed separately on the first end 8 and the second end 9. When the first end 8 and the second end 9 are connected to the columnar barrel 7, the first gear 24 and the second gear 25 can be installed in place at the same time.

[0049] In some embodiments, Figure 1 , 2 , 11, 13, 14, 15, in this example, the first rack 26 and the second rack are respectively arranged at the two side edges of the cover plate 2. In this way, it is conducive to the smooth and reliable opening and closing of the cover plate 2.

[0050] In some embodiments, Fig.12 , 13 As shown in 14 and 15, the cover plate 2 adopts a bendable integrated curling cover plate 2. In this way, due to the integrated structure, the curling deformation noise is small when opening and closing.

[0051] The cover plate 2 is a rollable one-piece structure manufactured by, for example, plastic one-piece molding, silicone one-piece molding, rubber one-piece molding or other processes.

[0052] When understanding the present disclosure, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0053] The above description is only an illustrative embodiment of the present invention, so any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
