[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] The following is for reference. Figure 1 and Figure 2 This invention describes a folding limiting structure for a car rearview mirror according to an embodiment of the present invention.

[0024] like Figure 1 and Figure 2 As shown, the folding limiting structure for a car rearview mirror according to an embodiment of the present invention includes a mirror body 100, a base 200, a limiting base plate 300, and a limiting sleeve 400.

[0025] The mirror body 100 can rotate horizontally around a vertical axis; the limiting plate 300 is connected to the upper side of the bottom wall of the mirror body 100, and a movable limiting ring 310 is provided on the lower side of the limiting plate 300. The movable limiting ring 310 has a through hole, and a movable limiting protrusion 320 is provided on the hole wall of the movable limiting ring 310; a connecting post 211 is provided on the upper side of the base 200; the limiting sleeve 400 includes an inner mounting ring 410, which is fitted onto the outer wall of the connecting post 211. The connecting post 211 and the inner mounting ring 410 extend into the movable limiting ring 310. A fixed limiting protrusion 420 is provided on the outer wall of the inner mounting ring 410, and the fixed limiting protrusion 420 can abut against the movable limiting protrusion 320 to limit the horizontal rotation range of the mirror body 100.

[0026] For example, such as Figure 1 and Figure 2 As shown, the mirror body 100 can rotate horizontally around a vertical axis, which is equivalent to the mirror body 100 being foldable and retractable. A limiting plate 300 is connected to the upper side of the bottom wall of the mirror body 100, meaning the limiting plate 300 rotates with the mirror body 100. A movable limiting ring 310 is provided on the lower side of the limiting plate 300, and the movable limiting ring 310 has a through hole. A movable limiting protrusion 320 is provided on the hole wall of the movable limiting ring 310, meaning the movable limiting protrusion 320 rotates with the mirror body 100.

[0027] The base 200 is relatively fixed. A connecting post 211 is provided on the upper side of the base 200. The limiting sleeve 400 includes an inner mounting ring 410. The inner mounting ring 410 is fitted onto the outer wall of the connecting post 211, and the connecting post 211 and the inner mounting ring 410 extend into the movable limiting ring 310. The inner mounting ring 410 is also relatively fixed within the movable limiting ring 310. A fixed limiting protrusion 420 is provided on the outer wall of the inner mounting ring 410. The fixed limiting protrusion 420 can abut against the movable limiting protrusion 320 to limit the horizontal rotation range of the mirror body 100.

[0028] In actual operation, the rotational folding movement of the mirror body 100 on the base 200 is limited by the cooperation of the limiting plate 300 and the limiting sleeve 400. (Refer to...) Figure 3 , Figure 4 When the mirror body 100 rotates, the movable limiting protrusion 320 on the lower side of the mirror body 100 also rotates. Meanwhile, the fixed limiting protrusion 420 on the base 200 remains stationary, limiting the rotation range of the mirror body 100. When the mirror body 100 rotates to a preset angle, the movable limiting protrusion 320 will abut against the fixed limiting protrusion 420, restricting further rotation of the mirror body 100.

[0029] Reference Figure 3 The design of the movable limiting protrusion 320 located on the hole wall of the movable limiting ring 310 reduces the space occupied by the movable limiting protrusion 320 within the through hole of the movable limiting ring 310 and around the movable limiting ring 310. Furthermore, the inner mounting ring 410 of the limiting sleeve 400 is fitted onto the outer wall of the connecting post 211, simplifying the installation of the limiting sleeve 400. Thus, when the mirror body 100 is installed on the base 200, the obstruction to the connecting post 211 on the base 200 and the inner mounting ring 410 of the limiting sleeve 400 extending into the movable limiting ring 310 on the lower side of the mirror body 100 is reduced, making the installation of the mirror body 100 easier.

[0030] In some embodiments of this utility model, the movable limiting protrusion 320 includes a first movable limiting portion 321 and a second movable limiting portion 322, which are arranged on the front and rear sides of the hole wall of the movable limiting ring 310, respectively. The fixed limiting protrusion 420 includes a first fixed limiting portion 421 and a second fixed limiting portion 422, which are arranged on the left and right sides of the outer side wall of the inner mounting ring 410, respectively. The front ends of the first fixed limiting portion 421 and the second fixed limiting portion 422 can abut against the first movable limiting portion 321, and the rear ends of the first fixed limiting portion 421 and the second fixed limiting portion 422 can abut against the second movable limiting portion 322.

[0031] The movable limiting protrusion 320 includes at least a first movable limiting part 321 and a second movable limiting part 322 distributed on the front and rear sides. That is, the first movable limiting part 321 is located on the front side of the hole wall, while the second movable limiting part 322 is located on the rear side. The two work together to form a limiting combination structure corresponding to the mirror body 100.

[0032] The fixed limiting protrusion 420 includes at least a first fixed limiting part 421 and a second fixed limiting part 422 distributed on the left and right sides, forming a limiting combination structure corresponding to the base 200. The front ends of the first fixed limiting part 421 and the second fixed limiting part 422 cooperate to effectively abut against the first movable limiting part 321, thereby ensuring the front end of the mirror body 100 is limited during movement. Similarly, the rear ends of the first fixed limiting part 421 and the second fixed limiting part 422 can also cooperate to abut against the second movable limiting part 322, ensuring the rear end of the mirror body 100 is limited during movement, thereby ensuring stability and accuracy when limiting the mirror body 100 throughout its entire movement.

[0033] In some embodiments of this utility model, reference is made to Figure 5 The vertical cross-section of the movable limiting protrusion 320 is a right-angled triangle. The upper side of the movable limiting protrusion 320 has a movable limiting protrusion plane 323, and the movable limiting protrusion 320 has a movable limiting protrusion inclined surface 324 near the vertical axis. The inclined surface 324 is inclined from the lower side away from the vertical axis to the upper side near the vertical axis. This structure of the movable limiting protrusion 320 not only ensures the structural strength of the movable limiting protrusion 320, but also prevents the inclined surface 324 from excessively colliding with the connecting post 211 and the limiting sleeve 400 during the installation of the mirror body 100, thus avoiding any impact on the assembly efficiency of the mirror body 100.

[0034] In some embodiments of this utility model, reference is made to Figure 6 The vertical cross-section of the fixed limiting protrusion 420 is a right-angled triangle. The upper side of the fixed limiting protrusion 420 has a fixed limiting protrusion plane 423, and the fixed limiting protrusion 420 has a fixed limiting protrusion inclined surface 424 near the vertical axis. The fixed limiting protrusion inclined surface 424 is inclined from the lower side away from the vertical axis to the upper side near the vertical axis. This structure of the fixed limiting protrusion 420 ensures its structural strength and makes it easier for the upper position of the fixed limiting protrusion 420 to cooperate with the upper position of the movable limiting protrusion 320, achieving the limiting effect.

[0035] A car rearview mirror according to other embodiments of the present invention includes a folding and limiting structure for a car rearview mirror according to the first aspect embodiment of the present invention described above, with reference to... Figure 2The mirror body 100 contains an integrated movement 500, which includes a fixed end 510 and a movable end 520. The fixed end 510 is connected to the upper end of the connecting post 211, and the movable end 520 is connected to the upper side of the limiting base plate 300. The fixed end 510 of the integrated movement 500 is relatively fixed, while the movable end 520 can rotate at least horizontally.

[0036] According to the embodiments of the present invention, the rearview mirror of the car uses the above-mentioned folding limiting structure applied to the rearview mirror, which reduces the number of related components of the rearview mirror, facilitates the simplified assembly design of the rearview mirror, and improves the stability of the rearview mirror during folding, thereby enhancing the user experience.

[0037] In some embodiments of this utility model, reference is made to Figure 1 The base 200 has a base fixing end 213 on its left or right side, and the base 200 is fixedly installed on the car through the base fixing end 213.

[0038] In some embodiments of this utility model, reference is made to Figure 8 The lower end of the connecting post 211 has a bottom opening 214, and the upper end of the connecting post 211 has a end plate 215. (Refer to...) Figure 2 The screw extends from the bottom opening 214 of the connecting post into the connecting post 211 and connects the connecting post end plate 215 to the movement fixing end 510 of the integrated movement 500. This achieves a fixed connection between the movement fixing end 510 of the integrated movement 500 and the connecting post 211 on the base 200.

[0039] In some embodiments of this utility model, the outer side of the movable end 520 of the movement is fixedly connected to the limiting base plate 300 by screws, thus realizing the fixed connection between the movable end 520 of the integrated movement 500 and the limiting base plate 300 inside the mirror body 100.

[0040] In some embodiments of this utility model, reference is made to Figure 7 The mirror body 100 has a bottom through hole 110 on its lower side. A limiting plate 300 covers the upper side of the bottom through hole 110. The upper side of the limiting plate 300 has a mechanism receiving cavity 330, and the integrated mechanism 500 is located inside the mechanism receiving cavity 330. In this way, the limiting plate 300 provides better protection for the integrated mechanism 500 and makes the connection between the integrated mechanism 500 and the mechanism receiving cavity 330 more stable and reliable.

[0041] In some embodiments of this utility model, the mirror body 100 has a lens 120 on the front side, the inner sidewall of the mirror body 100 has a front buckle 130 on the front side, the limiting base plate 300 has a base plate front support surface 340 on the front side, the base plate front support surface 340 has a locking hole 341, the front buckle 130 is inserted into the locking hole 341, thereby improving the stability of the limiting base plate 300 in the direction of the front lens 120 of the mirror body 100, making the car rearview mirror more stable and reliable.

[0042] In some embodiments of this utility model, reference is made to Figure 8 The base 200 includes a base cover 220 and a base support frame 210. The base cover 220 is located on the upper side of the base support frame 210 and has a base cover through hole 221. A connecting post 211 is located on the base support frame 210 and extends upward through the base cover through hole 221. The limiting sleeve 400 includes an outer support ring 430, which is located outside the inner mounting ring 410. A limiting sleeve annular groove 440 is formed between the inner sidewall of the outer support ring 430 and the outer sidewall of the inner mounting ring 410. The outer sidewall of the outer support ring 430 abuts against the hole wall of the base cover through hole 221.

[0043] The base 200 consists of at least two parts: a base cover 220 and a base support frame 210. The base cover 220 is installed on the upper side of the base support frame 210 as an upper cover structure. The base cover through hole 221 of the base cover 220 facilitates the insertion and connection of the connecting column 211 or other components. The base support frame 210 serves as the main support structure, and the connecting column 211 is located above the base support frame 210. Its function is to extend upward through the base cover through hole 221, thereby achieving effective connection with other structures such as the mirror body 100 and the limiting base plate 300.

[0044] An annular groove 440 is formed between the outer support ring 430 and the outer side wall of the inner mounting ring 410 of the limiting sleeve 400. The presence of this annular groove provides a certain degree of elasticity and buffer space between the outer support ring 430 and the inner mounting ring 410. In this way, the outer support ring 430 is in close contact with the through hole 221 of the base cover and forms a supporting force, ensuring the stability and accuracy of the limiting sleeve 400, and preventing displacement or loosening of the limiting sleeve 400 during the limiting process.

[0045] In some embodiments of this utility model, reference is made to Figure 7 , Figure 8 The outer support ring 430 has an outer support ring mounting hole 431, and the base cover through hole 221 has an outer support ring first insertion part 222. The outer support ring first insertion part 222 is inserted into the outer support ring mounting hole 431 to ensure that the outer support ring 430 of the limit sleeve 400 is firmly connected to the base 200.

[0046] In some embodiments of this utility model, a bottom buckle 450 is provided on the lower side of the limiting sleeve 400, and a bottom buckle groove 451 is provided on the lower side of the bottom buckle 450. A second insertion part 212 of the outer support ring is provided on the upper side of the base support frame 210. The second insertion part 212 of the outer support ring is located on the outer wall of the connecting column 211. The upper end of the second insertion part 212 of the outer support ring is inserted into the bottom buckle groove 451 to ensure that the limiting sleeve 400 and the base 200 are stably connected.

[0047] Other components and operations of the car rearview mirror according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.

[0048] The following is for reference. Figure 1 and Figure 2 A folding limiting structure for an automobile rearview mirror according to an embodiment of the present invention is described in detail below. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0049] like Figure 1 and Figure 2 As shown, the rearview mirror of the car according to this utility model embodiment includes a mirror body 100, a base 200, a limiting base plate 300, a limiting sleeve 400 and an integrated mechanism 500.

[0050] The mirror body 100 is provided with a bottom through hole 110, a lens 120, and a front latch 130. A limiting base plate 300 is located within the mirror body 100. The limiting base plate 300 is provided with a movable limiting ring 310, a movable limiting protrusion 320, a first movable limiting part 321, a second movable limiting part 322, a movable limiting protrusion plane 323, a movable limiting protrusion inclined surface 324, a movement receiving cavity 330, a base plate front support surface 340, and a latching hole 341. An integrated movement 500 is located within the limiting base plate 300. The integrated movement 500 includes a movement fixing end 510 and a movement movable end 520.

[0051] The base 200 includes a base support frame 210, a connecting column 211, a second insertion part 212 of the outer support ring, a base fixing end 213, a bottom opening 214 of the connecting column, a connecting column end plate 215, a base cover 220, a through hole 221 of the base cover, and a first insertion part 222 of the outer support ring. A limiting sleeve 400 is located on the base 200. The limiting sleeve 400 includes an inner mounting ring 410, a fixing limiting protrusion 420, a first fixing limiting part 421, a second fixing limiting part 422, a fixing limiting protrusion plane 423, a fixing limiting protrusion inclined surface 424, an outer support ring 430, an outer support ring mounting hole 431, a limiting sleeve annular groove 440, a limiting sleeve bottom buckle 450, and a bottom buckle groove 451.

[0052] According to the folding limiting structure applied to a car rearview mirror according to the embodiment of this utility model, the following effects can be achieved by the following configuration: the mirror body 100 is limited by the cooperation of the limiting base plate 300 and the limiting sleeve 400; when the mirror body 100 rotates to a preset angle, the movable limiting protrusion 320 will abut against the fixed limiting protrusion 420, restricting the mirror body 100 from continuing to rotate; the design of the movable limiting protrusion 320 being located on the hole wall of the movable limiting ring 310 means that the movable limiting protrusion 320 does not need to occupy too much space in the through hole of the movable limiting ring 310 and around the movable limiting ring 310. Furthermore, the inner mounting ring 410 of the limiting sleeve 400 is fitted onto the outer wall of the connecting post 211, which also simplifies the installation of the limiting sleeve 400. When the mirror body 100 is installed on the base 200, the obstruction is reduced when the connecting post 211 on the base 200 and the inner mounting ring 410 of the limiting sleeve 400 extend into the movable limiting ring 310 on the lower side of the mirror body 100, making the installation of the mirror body 100 easier.
