The basic arc ridge 31 is located in the basic arc groove 112, and the transitional spherical shell 3 rotates relative to the fixed seat 11 along the extension direction of the basic arc ridge 31. A matching arc ridge 32 is fixedly provided on the concave surface of the transitional spherical shell 3, and a matching arc groove 24 is provided on the convex surface of the matching spherical shell 21.

That is, when the driving gear 41 outputs torque to one of the first racks 441, the damping gear 42 outputs resistance torque to the other first output rack, thereby improving the balance of the mirror mounting plate 2 on the plane where the extension trajectory of the first rack 441 is located, and the same is true for the second rack 442.

[0033] like Figure 1 and 3As shown, the control assembly 43 is used to rotate the driving gear 41, which includes a driving motor 431, a driving worm 432, a driving worm wheel 433, a relay worm 434 and a relay worm wheel 435.

The driving motor 431 transmits torque to the driving gear 41 through two sets of worm wheels.

[0034] like Figure 4 As shown, the first rack 441 is detachably mounted on the mirror mounting plate 2, a mounting shaft 4411 is fixedly connected to the first rack 441, a side wall of the mounting shaft 4411 at one end away from the first rack 441 is fixedly connected to a limiting protrusion 4412, a mounting hole 22 is provided on the mirror mounting plate 2 for the mounting shaft 4411 to pass through, and a limiting matching groove 221 is provided on the hole wall of the mounting hole 22 for the limiting protrusion 4412 to pass through.

[0035] like Figure 4 As shown, a mounting groove 4421 is provided on the second rack 442, and the length direction of the mounting groove 4421 is perpendicular to the plane where the trajectory of the second rack 442 is located. A limiting clamping edge 4422 is fixedly connected to the groove wall at the groove mouth of the mounting groove 4421, and a mounting protrusion 23 is fixedly connected to the mirror mounting plate 2, and a matching edge 231 is fixedly connected to the edge of the mounting protrusion 23. After the mounting protrusion 23 is embedded in the mounting groove 4421, the matching edge 231 is located on the side of the limiting clamping edge 4422 facing the bottom of the mounting groove 4421, and the mounting protrusion 23 cannot fall out of the mounting groove 4421 along a direction perpendicular to the length of the mounting groove 4421. The protruding distance of the middle part of the mating edge 231 relative to the mounting protrusion 23 is greater than the protruding distance of the two sides relative to the mounting protrusion 23. In this embodiment, the mating edge 231 has a pointed shape, the middle part of which contacts the groove wall of the mounting groove 4421, while the two sides do not contact the groove wall of the mounting groove 4421, so that the second rack 442 can rotate relative to the mounting protrusion 23 in the installed state.

[0036] like Figure 1 and 2As shown, the edge of the buckle mount 12 is fixedly connected with a plurality of cantilever arc surface pieces 121, and the plurality of cantilever arc surface pieces 121 are arranged in a circumferential array along the buckle mount 12, and gaps are formed between adjacent cantilever arc surface pieces 121, and the cantilever arc surface pieces 121 are in close contact with the concave surface of the mating spherical shell 21. The cantilever arc surface piece 121 is a cantilever structure provided at the edge of the buckle mount 12, and both have the characteristics of elastic deformation. During the rotation of the buckle mount 12 relative to the mating spherical shell 21, the cantilever arc surface piece 121 can be adaptively abutted against various places of the concave surface of the mating spherical shell 21, thereby improving the degree of fit between the edge of the buckle mount 12 and the mating spherical shell 21, thereby improving the stability of the mating spherical shell 21 relative to the base 1 when the motion is in progress.

[0037] Embodiment 2: like Figure 5 As shown, on the basis of the first embodiment, in this embodiment, an oil-increasing bin 5 is fixedly provided at the edge of the concave surface of the mating ball shell 21, an oil storage cavity 54 is provided in the oil-increasing bin 5, an oil-injection gap 56 is formed on the side of the oil-increasing bin 5 facing the buckle mount 12, and the oil-injection gap 56 is communicated with the oil storage cavity 54; an oil-seeping body 55 is placed in the oil storage cavity 54, and the oil-seeping body 55 can be a sponge. The oil-increasing bin 5 is composed of a fixed portion 51, an elastic deformation portion 52 and an abutment portion 53 in the direction gradually approaching the buckle mount 12, the fixed portion 51 and the mating ball shell 21 are integrally formed, the elastic deformation portion 52 is integrally formed between the fixed portion 51 and the abutment portion 53, and the oil-injection gap 56 is located between the abutment portion 53 and the concave surface of the mating ball shell 21. When the driving mechanism 4 controls the mirror mounting plate 2 to rotate until the oil increasing tank 5 contacts the edge of the cantilever arc piece 121, the cantilever arc piece 121 and the abutting part 53 abut each other. After the abutting part 53 is subjected to force, the elastic deformation part 52 is deformed, the space in the oil storage cavity 54 is reduced, and the oil seeping body 55 is squeezed. The oil attached to it seeps out and flows out through the oil filling gap 56 and contacts the cantilever arc piece 121. Then, as the cantilever arc piece 121 contacts and rubs against the concave surface of the mating spherical shell 21, the oil spreads on the concave surface of the mating spherical shell 21, thereby improving the lubrication effect during the relative friction between the two.

[0038] like Figure 5 As shown, a plurality of oil-passing capillary holes 211 are formed through the mating spherical shell 21, and the oil on the concave side of the mating spherical shell 21 can penetrate into the convex side of the mating spherical shell 21 through the oil-passing capillary holes 211 and contact the transition spherical shell 3, thereby improving the lubrication effect when the transition spherical shell 3 and the mating spherical shell 21 are in relative friction.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
