Detailed Implementation
[0035] Example 1
[0036] The following is combined Figures 1-7 This utility model will be described in detail.
[0037] A hinge device 10 includes two connecting members 20 that are hinged together at their middle parts. The first end of each connecting member 20 is provided with a first guide portion, and the two ends of each connecting member 20 are respectively provided with a base. The base is provided with a second guide portion. The first guide portion is slidably connected to the second guide portion on the corresponding side. One of the first guide portion and the second guide portion is a guide groove 90 and the other is a guide protrusion 80. The second ends of the two connecting members 20 are hinged to the base on the corresponding side.
[0038] It also includes an initial limiting surface and a final limiting surface, which are provided in at least one guide groove 90; or, each is provided in two guide grooves 90 respectively.
[0039] In use, the two bases can rotate back and forth relative to each other, having an initial position and a final position during rotation. In the initial position, the guide protrusion 80 abuts against the initial limiting surface; in the final position, the guide protrusion 80 abuts against the final limiting surface, thereby limiting the angle of movement between the two bases. This reduces interference between the mirror surfaces and exposure of hardware during the opening and closing of the lamp mirror using this hinge device 10, improving the user experience. In this embodiment, both guide grooves 90 are provided with initial and final limiting surfaces to enhance the limiting effect.
[0040] In this embodiment, the base is provided with a receiving groove 502, which forms an active space for the sliding of the connector 20. At least one wall surface of the receiving groove 502 is provided with a guide groove 90, which forms a second guide portion. The first end of the connector 20 is provided with a guide protrusion 80. Specifically, the movable shaft 40 passes through the first end of the connector 20, and the portions of the movable shaft 40 protruding from the connector 20 at both ends form the guide protrusion 80, which forms a first guide portion. In other embodiments, the guide protrusion 80 may also be integrally formed on the connector 20.
[0041] When the base is in its initial position, such as Figure 2 As shown, the guide protrusion 80 abuts against the initial limiting surface. When the base is in the termination position, as... Figure 6 As shown, the guide protrusion 80 abuts against the termination limiting surface. In other embodiments, the positions of the guide groove 90 and the guide protrusion 80 can be interchanged, that is, at least one wall surface in the receiving groove 502 is provided with the guide protrusion 80, and the first end of the connector 20 is provided with the guide groove 90, and its limiting principle is the same as described above.
[0042] In this embodiment, as Figure 7 As shown, the two opposing walls of the receiving groove 502 are provided with guide grooves 90, and the two sides of the first end of the connector 20 are provided with guide protrusions 80, so that the two sides of the first end of the connector 20 and the base form a guide structure that is adapted to the concave and convex shape. On the one hand, it stabilizes the movement state of the connector 20, and on the other hand, it provides more limiting contact surfaces to ensure the limiting effect.
[0043] In this embodiment, as Figure 7As shown, the base includes a body 50 and a base 60 connected to the body 50. The body 50 has a receiving groove 502 and a guide groove 90. The second end of the connector 20 is hinged to the base 60 on the corresponding side. A plug 70 is provided at the end of the guide groove 90 away from the base 60. The plug 70 can be installed in the guide groove 90 by means of threaded connection, welding, bonding, or snap-fit. When the two bases are in the initial position, the guide protrusion 80 abuts against the plug 70, and the surface of the plug 70 abuts against the guide protrusion 80 to form an initial limiting surface. When the two bases are in the final position, the guide protrusion 80 abuts against the base 60, and the surface of the base 60 abuts against the guide protrusion 80 to form a final limiting surface. The base 60 is used to connect the cabinet 110. Therefore, the base 60 serves both a limiting function and a connecting function to the cabinet 110, thereby reducing the number of parts and lowering production costs.
[0044] In this embodiment, as Figure 7 As shown, the body 50 has a connecting hole 501, and the base 60 has a locking hole 601. Fasteners are inserted through the connecting hole 501 and threaded into the locking hole 601, thereby connecting the base 60 to the base. In other embodiments, the base 60 can also be connected by welding, bonding, or snap-fitting.
[0045] In this embodiment, as Figure 7 As shown, the base 60 is provided with a relief groove 100 for the adapter connector 20. Further, the relief groove 100 includes a first relief groove 1001 and a second relief groove 1002, and the connector 20 includes a first connecting position 201 and a second connecting position 202 connected to each other. The first connecting position 201 is hinged to the first relief groove 1001, and the second connecting position 202 is slidably connected to the second relief groove 1002 of the other base 60. When the base is in its initial position, as... Figure 1 As shown, the first connecting position 201 is completely housed within the first clearance groove 1001, reducing the distance between the two bases and thus reducing the gap between the two mirror surfaces connected to the bases, thereby improving aesthetics; when the base is in the termination position, as... Figure 6 As shown, the second clearance groove 1002 provides more space for the second connection position 202, increasing the angle of relative rotation between the two bases.
[0046] In this embodiment, there is an angle between the first connecting position 201 and the second connecting position 202, and a mounting groove 203 is provided between the first connecting position 201 and the second connecting position 202. The two connecting members 20 are mutually fitted through the mounting groove 203, that is, the connection points of the first connecting positions 201 and the second connecting positions 202 of the two connecting members 20 are respectively located in the mounting groove 203 of the other, thereby reducing the size of the two connecting members 20 after they are hinged together. The connection points of the first connecting position 201 and the second connecting position 202 are provided with mutually fitted pivot holes, and the two ends of the pivot shaft 30 are respectively connected to the corresponding pivot holes, so that the two connecting members 20 can rotate relative to each other.
[0047] In this embodiment, the angle range corresponding to the rotation of the two bases from the initial position to the final position is 0 degrees to 95 degrees. In other embodiments, the rotation angle range of the bases can be changed by modifying the length of the guide groove 90 or the size of the guide protrusion 80 to limit the stroke of the guide protrusion 80.

Two bases are respectively connected to the main mirror assembly 120 and the side mirror assembly 130, so that the side mirror assembly 130 can rotate relative to the main mirror assembly 120 to an initial position and an end position, thereby avoiding the problem of mirror interference.
[0051] In this embodiment, side mirror assemblies 130 are provided on both sides of the main mirror assembly 120. Both side mirror assemblies 130 and the main mirror assembly 120 are provided with the hinge device 10 described above, and the number of hinge devices 10 between the side mirror assembly 130 and the main mirror assembly 120 is at least two to ensure the connection strength between the side mirror assembly 130 and the main mirror assembly 120. Light-emitting elements are provided around the main mirror assembly 120 and the side mirror assembly 130. The light-emitting elements are generally LED light strips. The main mirror assembly 120 is provided with an operating element 140 for controlling the opening and closing of the light-emitting elements. The operating element 140 is a touch button, a sensor button, or a mechanical button.
[0052] In this embodiment, Figure 8 The diagram shows the positional states of the side mirror assembly 130 and the main mirror assembly 120 when the hinge device 10 is in its initial position, at which point the included angle between the side mirror assembly 130 and the main mirror assembly 120 is 180 degrees. Figure 10 The positional states of the side mirror assembly 130 and the main mirror assembly 120 are shown when the hinge device 10 is in the terminated position, at which time the angle between the side mirror assembly 130 and the main mirror assembly 120 is 95 degrees. Figure 9 The positional states of the side mirror assembly 130 and the main mirror assembly 120 are shown when the hinge device 10 is in a transitional position between the initial position and the final position.
[0053] In this embodiment, the inner frame of the side mirror assembly 130 and the main mirror assembly 120 has sufficient space for placing LED light strips. The power supply for the light strips is located inside the main mirror assembly 120. The frame has a wire hole. The LED light strip in the side mirror assembly 130 is connected to the power supply located in the main mirror assembly 120 through the wire hole, so as to complete the function of the operating member 140 to activate the LED light strips of the side mirror assembly 130 and the main mirror assembly 120 in a coordinated manner.
