[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0028] Please refer to Figures 3 to 7 As shown, the positioning member of the rearview mirror folder of the present invention includes a blocking portion 12 and an elastic portion 11 connected to each other; the elastic portion 11 is an "h" shape;

[0029] The elastic portion 11 includes a first elastic piece 111 and a second elastic piece 112. One end of the second elastic piece 112 is connected to the middle of the first elastic piece 111. There is a gap between the first elastic piece 111 and the second elastic piece 112. Preferably, the elastic portion 11 is integrally formed.

[0030] As can be seen from the above description, the beneficial effects of the present invention are as follows: the blocking portion 12 prevents reverse rotation of the gear, the H-shaped elastic portion 11 provides the required displacement space during rotation, and the compact structure of the positioning member 1 helps reduce the overall size of the rearview mirror folder or provide more space for other installation components. Furthermore, the elastic portion 11 is not a traditional spring or torsion spring structure, but rather an H-shaped structural member with a certain degree of toughness and rigidity. The elastic portion 11 can be integrally molded by injection molding. One end of the second elastic member 112 smoothly transitions with the first elastic member 111, creating a gap between the two elastic members to provide a certain amount of displacement space during gear rotation. Compared to traditional positioning structures with similar functions, this is more compact and space-saving. The center of the first elastic member 111 does not necessarily need to be the center, center of gravity, or center of mass; it can be located between the two ends of the first elastic member 111, ensuring that sufficient space is left above the first elastic member 111 for connection to the housing 3.

[0031] Furthermore, the other end of the second elastic piece 112 is connected to the blocking portion 12 .

[0032] Furthermore, the other end of the second elastic piece 112 has a buckle 113 , and the blocking portion 12 has a slot 121 adapted to the buckle 113 .

[0033] From the above description, it can be seen that the other end of the second elastic piece 112, that is, the end not connected to the first elastic piece 111, is connected to the blocking portion 12, preferably by snapping. Through the design of the buckle 113 and the slot 121, the two are detachably connected. This type of snap-on structure is convenient for installation and can provide a stable connection structure during movement.

[0034] Furthermore, the elastic portion 11 is made of an organic polymer material, while the barrier portion 12 is made of a metal material. By making the elastic portion of an organic polymer material, such as PP, PE, PVC, PS, PA, or various modified plastics, the elasticity of the elastic portion can be effectively improved to prevent breakage, while the barrier portion is made of a metal material, such as stainless steel or aluminum alloy, to effectively improve wear resistance.

[0035] Reference Figures 1 to 7 As shown, the rearview mirror folder of the present invention includes the positioning member 1 mentioned above.

[0036] The rearview mirror folding device further includes a gear assembly 2 and a housing 3. A blocking portion 12 abuts against the gear assembly 2, and an elastic portion 11 is connected to the housing 3. A positioning member 1 is used to block the gear assembly 2, allowing it to rotate in only one direction, such as clockwise or counterclockwise. Both the positioning member 1 and the gear 2 are disposed within the housing 3.

[0037] From the above description, it can be seen that the beneficial effect of the present invention is that: when the gear assembly 2 rotates in the reverse direction, the blocking portion 12 of the positioning member 1 will press against the gear assembly 2, so that the gear assembly 2 cannot rotate in the reverse direction. At the same time, the elastic member can provide a displacement space required to move due to the extrusion of the gear assembly 2, so that the positioning member 1 remains connected to the housing 3 without being damaged due to movement.

[0038] Furthermore, the gear assembly 2 includes an annular positioning boss 21, the outer circumferential surface of which is provided with at least one positioning block 22, and the positioning block 22 has a stop surface 23. One side of the positioning block 22 is connected to the positioning boss 21, and the opposite side has an arcuate surface that can rotate relative to the stop block. One end of the arcuate surface smoothly transitions with the positioning boss 21 (smooth transition), and the other end is connected to the stop surface 23. When the blocking portion 12 contacts the stop surface 23, the gear assembly 2 cannot rotate in the opposite direction. In one or more embodiments, the volume and cross-sectional area of the positioning block 22 gradually increase from the end that smoothly transitions with the positioning boss 21 to the end having the stop surface 23.

[0039] Furthermore, the gear assembly 2 further includes an annular connecting body 24, the outer circumference of which is provided with a gear ring 25; the positioning boss 21 is connected to the connecting body 24. The connecting body 24 and the positioning boss 21 are coaxially arranged.

[0040] Furthermore, the horizontal projections (orthographic projections in the horizontal plane direction) of the positioning boss 21 and the positioning block 22 are both located within the horizontal projections of the connecting body 24 and the gear ring 25 .

[0041] It can be seen from the above description that the above structure ensures that the blocking portion 12 can be stably placed on the gear assembly 2 .

[0042] Furthermore, the connecting body 24 and the gear ring 25 both have an upper end surface and a lower end surface, and the positioning boss 21 is connected to the upper end surface of the connecting body 24;

[0043] In one or more embodiments, a side surface (b-surface 123) of the blocking portion 12 interferes with the outer circumferential surface of the positioning boss 21 and, at certain moments during rotation, interferes with the arcuate surface of the positioning block 22. A bottom surface (a-surface 122) interferes with the upper end surfaces of the connecting body 24 and the gear ring 25. Preferably, the bottom surface (a-surface 122) and the side surface (b-surface 123) are perpendicular and adjacent to each other.

[0044] The positioning member 1 provided by the utility model is used in a rearview mirror folder to ensure that the gear assembly 2 can only rotate forward and cannot be reversed. It can also be used in other devices that need to prevent the gear assembly 2 from reversing.

[0045] Please refer to Figures 3 to 7 As shown, the first embodiment of the present utility model is:

[0046] The positioning member of the rearview mirror folder includes a blocking portion 12 and an elastic portion 11 connected to each other; the elastic portion 11 is an "H" shape;

[0047] The elastic part 11 includes a first elastic piece 111 and a second elastic piece 112, one end of the second elastic piece 112 is connected to the middle part of the first elastic piece 111, and the other end has a buckle 113; there is a gap between the first elastic piece 111 and the second elastic piece 112; the blocking part 12 has a slot 121 adapted to the buckle 113, and the other end of the second elastic piece 112 is snap-connected to the blocking part 12.

[0048] Please refer to Figures 1 to 7 As shown, the second embodiment of the present utility model is:

[0049] A rearview mirror folder, comprising a positioning member 1, a gear assembly 2 and a housing 3;

[0050] The positioning member 1 includes a blocking portion 12 and an elastic portion 11 that are interconnected. The elastic portion 11 is shaped like an "H." The elastic portion 11 includes a first elastic piece 111 and a second elastic piece 112. One end of the second elastic piece 112 is connected to the middle of the first elastic piece 111, and the other end has a buckle 113. A gap is formed between the first and second elastic pieces 111, 112. The blocking portion 12 has a slot 121 that matches the buckle 113. The other end of the second elastic piece 112 (the end with the buckle 113) is engaged with the blocking portion 12.

[0051] The gear assembly 2 includes an annular positioning boss 21 and an annular connecting body 24; the outer circumferential surface of the connecting body 24 is provided with a gear ring 25; the outer circumferential surface of the positioning boss 21 is provided with a positioning block 22, the positioning block 22 having a stop surface 23 and an arcuate surface, one end of the arcuate surface smoothly transitions with the positioning boss 21, and the other end is connected to the stop surface 23; the horizontal projections of the positioning boss 21 and the positioning block 22 are both located within the horizontal projections of the connecting body 24 and the gear ring 25; the connecting body 24 and the gear ring 25 each have an upper end surface and a lower end surface, and the positioning boss 21 is connected to the upper end surface of the connecting body 24;

[0052] The blocking portion 12 is in conflict with the gear assembly 2 , and the first elastic piece 111 is connected to the housing 3 ; the positioning member 1 is used to block the gear assembly 2 so that it can only rotate in one direction.

[0053] The working principle / working process of the present invention is as follows: the driving device of the rearview mirror folder drives the gear assembly 2 to rotate. During the forward rotation process, a bottom surface (such as surface a) of the blocking portion 12 always slides against the upper end surface of the connecting body 24 and the gear ring 25, while a side surface (such as surface b) of the blocking portion 12 sometimes slides against the outer peripheral surface of the positioning boss 21 and sometimes slides against the arcuate surface of the positioning block 22. Since the positioning block 22 has a protruding stop surface 23, when the gear assembly 2 rotates in the reverse direction, the blocking portion 12 will abut against the stop surface 23, so that the gear assembly 2 cannot achieve reverse rotation.

[0054] During the forward rotation process, one side surface of the blocking portion 12 (such as surface b) is in relative conflict with the outer peripheral surface of the positioning boss 21. At this time, the first spring piece 111 and the second spring piece 112 are in an uncompressed state. When the gear assembly 2 rotates to the positioning block 22, it slides relative to the arc surface of the positioning block 22, so that the blocking portion 12 gradually approaches the first spring piece 111. At this time, the second spring piece 112 is in a gradually squeezed state, and the space between the second spring piece 112 and the first spring piece 111 is used to provide the displacement space required at this time.

[0055] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
