Description

Technical Field

[0001] The invention relates to a car sun visor, in particular to a sun visor with a cosmetic mirror. Background Art

[0002] The sun visor has a unique function as a vehicle accessory, that is, it not only has a certain sunshade effect, but also has a mirror surface for the driver and passengers to use.

[0003] The sun visor is hinged to the car body roof by an L-shaped axis, and the position and posture of the sun visor can be adjusted to implement sun protection. The back of the sun visor, that is, the back of the sun visor surface, is arranged with a mirror for the driver and passengers to use. In order to improve the lack of brightness in the car, some designers have added fill lighting fixtures to the sun visor.

[0004] The technical solution provided by the patent application "A car sun visor" (application publication number CN 104129258A) is as follows: the control principle of the makeup mirror light switch is as follows: 1. When the makeup mirror slide cover is opened, Figure 4 As shown, when the sliding cover touches the V-shaped bent conductive copper sheet 111, the V-shaped bent conductive copper sheet 111 contacts the circular conductive copper sheet 501, turning the vanity mirror light on. When the vanity mirror sliding cover is closed, the V-shaped bent conductive copper sheet 111 and the circular conductive copper sheet 501 separate due to the elasticity of the copper sheets themselves, turning the vanity mirror light off. Secondly, when the vanity mirror sliding cover is open and the sun visor is flipped, during normal use of the sun visor vanity mirror, the main support shaft tube conductive copper sheet 9 contacts the two S-shaped copper sheets 10 of the vanity mirror light, turning the vanity mirror light on. When the sun visor is flipped, when the sun visor is in a state of contact with the roof or the front windshield, the main support shaft tube conductive copper sheet 9 and the two S-shaped copper sheets 10 of the vanity mirror light are no longer in contact, turning the vanity mirror light off. The two disclosed solutions are: one is to slide the vanity mirror sliding cover, and the other is to flip the sun visor to turn the vanity mirror light on or off. In the first solution, the sliding cover of the makeup mirror seriously occupies the mirror surface area of ​​the makeup mirror; in the second solution, the position and posture of the flip sun visor change, and the user also needs to adjust the position and posture accordingly, which brings inconvenience to use.

[0005] The technical solution provided by the patent application entitled "A car sun visor with a double-lens makeup mirror" (application publication number CN215244277U) is as follows: the lens 8 is coated with a reflective coating on the central part of the back, and the periphery is an annular light-transmitting area without coating; an LED atmosphere backlight 11 is arranged on the back of the makeup mirror, and the light of the LED atmosphere backlight 11 is emitted through the annular light-transmitting area around the lens. The circuit control principle of the makeup light is as follows: when the flip-up mirror cover 4 is closed, the first circuit board and the second circuit board are separated, the LED atmosphere backlight circuit is disconnected, and the LED atmosphere backlight is turned off; when the flip-up mirror cover 4 is opened, the boss 4-1 on the inner side of the upper edge of the mirror cover 4 pushes the first circuit board 13-1 inward through the flipping action of the flip-up mirror cover 4, so that the first circuit board 13-1 and the second circuit board 13-2 are engaged, and the circuit of the LED atmosphere backlight 11 is turned on, and the LED atmosphere backlight 11 lights up. The first circuit board 13-1 and the second circuit board 13-2 in the above scheme are two independent circuit boards, and two double lenses need to be set up accordingly. The light is irradiated along the light-transmitting area around the edge of the lens 8, and the actual use area of ​​the lens 8, that is, the area of ​​the reflective mirror surface, is very small.

[0006] The application is titled "A car sun visor with a double-lens makeup mirror" (application publication number CN110303855A). A contact spring 104 is provided on the skeleton 102 and on one side of the rotating shaft 101. One end of the contact spring 104 is electrically connected to the PCB board 302, and the other end contacts the surface of the rotating shaft 101. A conductive copper sheet 105 with a set central angle is provided on the circumference of the contact portion of the rotating shaft 101. The conductive copper sheet 105 and the rotating shaft 101 are made into one piece using an injection molding process.

[0007] When the sun visor is in the ceiling-mounted position, the contact spring 104 and the conductive copper sheet 105 are not in contact, and the LED light is disconnected. This embodiment proposes setting the angle to 155 degrees, that is, when the sun visor is in the ceiling-mounted position and rotated 25 degrees to 180 degrees, the contact spring 104 and the conductive copper sheet 105 are in contact and conductive.

[0008] The above-mentioned contact spring 104 is equivalent to the static contact of the switch, and the conductive copper sheet 105 is equivalent to the moving contact of the switch. The coordinated state of the static contact and the moving contact constitutes the on or off state of the switch. Since the conductive copper sheet 105 and the rotating shaft 101 are made into one piece by the injection molding process, the conductive copper sheet 105 may be scratched by passing through the rotating shaft 101. Since the suspended edge of the contact spring 104 extends to one side of the rotating shaft 101 and the folded edge direction of the contact spring 104 is arranged perpendicular to the axis core of the rotating shaft 101, the contact between the contact spring 104 and the rotating shaft 101 is point contact, so the conductive performance cannot be guaranteed. Summary of the Invention

[0009] The purpose of the present invention is to provide a sun visor with a cosmetic mirror, which not only has the basic functions of sun shading and mirror, but also ensures that the mirror area is of appropriate size and can provide a fill light effect.

[0010] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a sun visor with a makeup mirror, comprising a sun visor body assembly, the upper end of the vertical rod of the L-shaped shaft is connected to the vehicle body, the horizontal rod of the L-shaped shaft is inserted into the upper part of the sun visor body assembly at the plate corner part at one end of the upper side of the sun visor body assembly and is parallel to the upper side of the sun visor body assembly, a power harness is passed through the hollow tube cavity of the L-shaped shaft, the outer terminal of the power harness is connected to the vehicle power supply, a makeup mirror is provided in the middle of the front of the sun visor body assembly, and the characteristic is that a fill light assembly is arranged in the clamping cavity between the makeup mirror and the sun visor body assembly, and the fill light assembly includes a PCB control board, and the PCB control board has a light emitting A lamp provides light to the location of the makeup mirror. The inner end of the power harness is connected to the power input end of the PCB control board. The PCB control board is electrically connected to the first and second contact springs of the switch. A mirror cover is provided on the mirror side of the makeup mirror. Ear shafts are provided at both ends of the upper edge of the mirror cover and are hingedly connected to the ear shaft holes on the sun visor body assembly. A conductive rod is provided at the edge of the mirror cover. When the mirror cover is closed on the mirror surface of the makeup mirror, the conductive rod on the mirror cover and the first and second contact springs of the switch are in a separated and matched position. When the mirror cover is flipped over to reveal the mirror surface of the makeup mirror, the conductive rod on the mirror cover and the first and second contact springs of the switch are in line or surface contact electrical connection.

[0011] The above scheme continues to use the prior art of setting a flip-up mirror cover on the mirror surface of the makeup mirror, so that a mirror area of ​​the makeup mirror with an appropriate reflection area can be obtained. The first and second contact springs of the switch at the power output end of the PCB control board are separated or contacted with the conductive rod set at the upper edge of the mirror cover to connect or disconnect the power circuit of the light-emitting lamp. Compared with the related switch settings in the prior art, it has the significant advantages of simple structure and easy assembly. At the same time, it ensures that the conductive rod and the first and second contact springs of the switch are in line or surface contact electrical connection, thereby improving the reliability of conduction.

[0014] Figure 3 、 6 They are Figure 2 、 5 AA and BB cross-sectional views;

[0015] Figure 4 、 7 They are Figure 3 、 6 A partial enlarged view of the . DETAILED DESCRIPTION

[0016] For the sake of convenience, the upper and lower parts of each part of the sun visor are first defined as follows: when the sun visor is arranged vertically and the edge of the sun visor body assembly 10 connected to the L-shaped shaft 40 is at the top, the mirror side facing the user is the front side, such as Figure 2 、 5 The status shown in the figure.

[0017] The sun visor with a makeup mirror provided by the present invention includes a sun visor body assembly 10, the upper end of the vertical rod 41 of the L-shaped shaft 40 is connected to the vehicle body, the horizontal rod 42 of the L-shaped shaft 40 is inserted into the upper part of the sun visor body assembly 10 at the plate corner part of one end of the upper side of the sun visor body assembly 10 and is parallel to the upper side of the sun visor body assembly 10, a power harness 50 is passed through the hollow tube cavity of the L-shaped shaft 40, and the outer terminal 51 of the power harness 50 is connected to the vehicle power supply, a makeup mirror 20 is provided in the middle of the front of the sun visor body assembly 10, and a fill light assembly 30 is arranged in the clamping cavity between the makeup mirror 20 and the sun visor body assembly 10, and the fill light assembly 30 includes a PCB control board 31, and a light-emitting lamp 32 is provided on the PCB control board 31, and the light-emitting lamp 32 provides illumination to the location of the makeup mirror 20. Light, the inner end of the power harness 50 is connected to the power input terminal of the PCB control board 31, and the PCB control board 31 is electrically connected to the first and second contact springs 33a and 33b of the switch. A mirror cover 60 is provided on the mirror side of the makeup mirror 20, and ear shafts 61 are provided at both ends of the upper edge of the mirror cover 60, which are hingedly connected to the ear shaft holes 11 on the sun visor body assembly 10. A conductive rod 62 is provided at the upper edge of the mirror cover 60. When the mirror cover 60 covers the mirror surface of the makeup mirror 20, the conductive rod 62 on the mirror cover 60 and the first and second contact springs 33a and 33b of the switch are in a separated and matched position. When the mirror cover 60 is flipped over to reveal the mirror surface of the makeup mirror 20, the conductive rod 62 on the mirror cover 60 and the first and second contact springs 33a and 33b of the switch are in line or surface contact electrical connection.

[0018] Combine Figure 1An example of the connection between the first and second contact springs 33a, 33b, the power harness 50, and the positive and negative electrodes on the PCB control board 31 is described as follows: the positive wire of the power harness 50 is connected to the positive terminal, i.e., the + pole, on the control board 31, and after passing through a load, such as a light-emitting lamp 32, is connected to the negative terminal, i.e., the - pole, on the control board 31 and electrically connected to the first contact spring 33a; the negative wire of the power harness 50 is connected to the control board 31 and electrically connected to the second contact spring 33b; the conductive rod 62 is rotated to connect the first and second contact springs 33a, 33b. At this time, the operating voltage is applied to the load, the light-emitting lamp 32, between the + and - poles on the control board 31, and the light-emitting lamp 32 emits light; the conductive rod 62 is rotated to disconnect the first and second contact springs 33a, 33b. At this time, there is no operating voltage on the load, and the light-emitting lamp 32 does not emit light.

[0019] For vehicle drivers and passengers, when they need to use the makeup mirror 20, they only need to flip over the mirror cover 60. The mirror surface of the makeup mirror 20 is naturally in an exposed state and the light-emitting lamp 32 is illuminated, providing a fill light effect. Even under extremely dim external light conditions, it can still be used normally. The conductive rod 62 on the mirror cover 60 cooperates with the first and second contact springs 33a and 33b of the switch connected to the PCB control board 31 to form a switch. The conductive rod 62 that rotates synchronously with the mirror cover 60 flipping upward can be regarded as the moving contact terminal of the switch, and the first and second contact springs 33a and 33b of the switch connected to the PCB control board 31 fixed on the sun visor body assembly 10 can be regarded as the static contact terminals. The separation and contact of the two constitute the switching action, and because the conductive rod 62 and the first and second contact springs 33a and 33b of the switch are in line or surface contact electrical connection, even if there is severe bumping during the vehicle driving process, the reliable connection state of the circuit can still be ensured.

[0020] The conductive rod 62 is a rod with a U-shaped or L-shaped cross section. The mirror cover 60 has a concave slot 63 on its upper edge. One side of the conductive rod 62 is inserted into the slot 63, while the other side is suspended outside the slot 63. The conductive rod 62 is a rod of a certain length with a U-shaped or L-shaped cross section. The conductive rod 62 is connected to the mirror cover 60 by using a portion of its edge in the cross section. Figure 4 、 7 As shown, the fixation is convenient and reliable; the other part of the plate is in a suspended state so as to maintain an appropriate distance with the first and second contact springs 33a, 33b of the switch, and to ensure that when the conductive rod 62 rotates, it forms a reliable contact-type electrical connection with the first and second contact springs 33a, 33b of the switch.

[0021] As a preferred solution, the cross section of the conductive rod 62 is L-shaped with an arc-shaped transition, such as Figure 3 、 4 , 6, and 7.

[0022] The length of the slot 63 on the mirror cover 60 is parallel to the upper edge of the mirror cover 60, and the slot 63 is oriented in a direction generally perpendicular to the mirror cover 60. For the purpose of this description, the direction generally perpendicular to the mirror cover 60 does not need to be absolutely perpendicular; a certain angle deviation is acceptable. The above-mentioned scheme is used to set the slot 63, and the length direction of the conductive rod 62 can be regarded as being arranged in parallel with the ear shafts 61 set at both ends of the upper edge of the mirror cover 60. Therefore, when the mirror cover 60 rotates around the axis of the ear shaft 61, the swinging path of the suspended upper plate body 622 of the conductive rod 62 located outside the slot 63 on the conductive rod 62 is determined. As long as the first and second contact springs 33a and 33b of the switch are set on the swinging path of the suspended upper plate body 622 of the conductive rod 62, the suspended upper plate body 622 of the conductive rod 62 outside the slot 63 will form a reliable interference fit with the first and second contact springs 33a and 33b of the switch to achieve electrical connection.

[0023] In order to achieve a reliable fixation of the conductive rod 62, a clamping block 631 is provided in the clamping slot 63. The clamping blocks 631 are arranged at intervals within the slot length of the clamping slot 63. The spacing area 632 between the lower edge of the clamping block 631 and the inner wall surface of the lower slot wall of the clamping slot 63 is used to clamp the L-shaped lower plate 621 of the conductive rod 62, which has an arc-shaped transition cross section. The above solution is to clamp the conductive rod 62 on the lower plate 621 of the conductive rod 62 by clamping a plurality of clamping blocks 631 arranged at intervals, so that the conductive rod 62 is reliably fixed. Figure 4 、 7 .

[0024] In order to ensure that the contact between the conductive rod 62 and the first and second contact springs 33a and 33b of the switch is at least line contact, and more preferably surface contact, when the conductive rod 62 is electrically connected, the cross-section of the first and second contact springs 33a and 33b of the switch is U-shaped or L-shaped. The line connecting the first and second contact springs 33a and 33b of the switch is parallel to the length direction of the conductive rod 62, and the surface of the first and second contact springs 33a and 33b of the switch is parallel to the length direction of the conductive rod 62. Therefore, it is ensured that the surface of the first and second contact springs 33a and 33b of the switch and the suspended upper plate 622 of the conductive rod 62 form a matching state in which the outer arc surfaces of each other are flush and in contact with each other. Figure 4 、 7 In the example given, the cross-sections of the first and second contact springs 33a and 33b of the switch are L-shaped with a relatively gentle curvature to achieve at least linear or, with a high probability, surface contact.

[0025] like Figure 4 、 7As shown, the suspended upper plate 622 on the conductive rod 62 is located on the upper part of the suspended upper sheet 331a, 331b of the first and second contact springs 33a, 33b of the switch, and the back parts of the two are adjacent sides. When the conductive rod 62 rotates, the upper plate 622 gradually swings downward and its back is pressed against the back of the upper sheet 331a, 331b, so that the upper plate 622 and the back of the upper sheet 331a, 331b are pressed against each other.

[0026] In order to conveniently and reliably fix the first and second contact springs 33a and 33b of the switch, the present invention adopts the following technical solution, that is, one side of the spring body of the first and second contact springs 33a and 33b of the switch is inserted into the clamping groove 12 at the upper side of the sun visor body assembly 10, and the other side of the spring body is cantilevered toward the rotation path of the conductive rod 62, that is, the lower sheet 332a and 332b are inserted into the clamping groove 12, and the upper sheet 331a and 331b are located outside the clamping groove 12 and extend toward the area where the rotation path of the conductive rod 62 is located.

[0027] The upper plates 331a, 331b of the first and second contact springs 33a, 33b located outside the engaging slot 12 extend toward and abut against the outer wall 633 of the lower slot wall of the engaging slot 63 that secures the conductive rod 62. This arrangement of the first and second contact springs 33a, 33b prevents the first and second contact springs 33a, 33b from vibrating up and down and colliding with other components when the vehicle is jolted, thereby generating unusual noise. Furthermore, the abutting position of the upper plates 331a, 331b of the first and second contact springs 33a, 33b also contributes to the rotational torque of the mirror cover 60 relative to the ear shaft 61, and this rotational torque forces the mirror cover 60 to maintain a stable closed position. Furthermore, the abutting force provided by the upper plates 331a, 331b generates a resistance to the swinging tendency of the mirror cover 60 in the open position, thereby supporting the mirror cover 60 in the flipped-open state, freeing the user's hands. In other words, the cooperation between the first and second contact springs 33a, 33b of the switch and the mirror cover 60 and the conductive rod 62, on the one hand, has the basic function of a switch; on the other hand, when the mirror cover 60 is closed, the stability of the cover is ensured, and when the mirror cover 60 is opened, it can maintain the opened state.

[0028] In this application, the PCB control board 31 is arranged at the upper edge of the makeup mirror 20 and adjacent to the back of the makeup mirror 20. A light guide strip 70 is arranged on the upper edge of the makeup mirror 20. Light emitted by the light fixtures 32 passes through the light guide strip 70 and is then scanned onto the mirror surface of the makeup mirror 20. The lighting provided by the arrangement of the light fixtures 32 in this manner can prevent light from directly hitting the user's eyes, achieving comfortable fill light while also achieving appropriate lighting efficiency.

[0029] To ensure the reliability and longevity of the sun visor, an L-shaped core tube 80 is inserted into the L-shaped shaft 40, through which the power harness 50 passes. The addition of the L-shaped core tube 80 significantly improves the reliability of the sun visor connection while ensuring the secure insertion of the power harness 50.

[0030] In order to facilitate the assembly of the L-shaped shaft rod 40 and the L-shaped core tube 80, the vertical rod 41 and the horizontal rod 42 of the L-shaped shaft rod 40 are connected as a whole by splitting or welding.
