Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to a pull-out sun visor. Background Art

[0002] The sun visors on cars are usually installed on the main driver's seat and the co-pilot's seat behind the windshield. By flipping the sun visors, they form a shield in the upper front and upper sides of the driver's line of sight, effectively blocking interfering light from the front and sides, improving driving comfort and safety.

[0003] At present, the automobile sun visor on the market usually includes a main support, a rotating shaft, a sun visor body and a makeup mirror. The main support is fixedly mounted on the frame sheet metal, one end of the rotating shaft is rotatably mounted on the main support, and the other end of the rotating shaft extends into the sun visor body and is rotatably connected. At the same time, the makeup mirror is mounted on the sun visor body, that is, when the sun visor body is flipped, the makeup mirror can be opened and closed. In addition, the makeup mirror of the existing sun visor is usually equipped with a fill light, and the structure in which the fill light is directly mounted on the sun visor or integrated on the makeup mirror is becoming more and more common. Therefore, a conductive structure needs to be arranged in the sun visor to realize the transmission of electrical energy. For example, patent CN104129258B discloses a car sun visor, which has two S-shaped copper sheets arranged opposite to each other and spaced apart, inside the sun visor body and at one end where the rotating shaft extends, the two S-shaped copper sheets are electrically connected to the circuit board of the fill light, and the two S-shaped copper sheets are respectively in contact with two opposite surfaces of the end of the rotating shaft, and at the same time, two long copper sheets are arranged on the end of the rotating shaft extending into the sun visor body and are respectively wrapped around two opposite side surfaces and end surfaces of the end of the rotating shaft, the rotating shaft is a hollow shaft, and two wires are extended from one end of the rotating shaft located at the main support into its hollow interior and then extend to one end extending into the sun visor body and are respectively connected to the two long copper sheets. When the sun visor is flipped to open the makeup mirror, the long copper sheet on the rotating shaft contacts the two S-shaped copper sheets, and the fill light is turned on. When the sun visor is flipped back to close the makeup mirror, the long copper sheet on the rotating shaft separates from the two S-shaped copper sheets, so that the fill light is turned off. This can not only meet the use requirements of the sun visor flipping, but also power the fill light of the makeup mirror on the sun visor. Although the above structure can meet the use requirements of the traditional shielding plate, due to the limited length of the vehicle sun visor and the fixed installation position of the main support, it can only block the front half of the vehicle side window when it is flipped to the side state, and the back half cannot be blocked. At this time, the driver is usually in the back half of the side window, and the shielding effect of the sun visor is limited, which still affects the comfort and safety of use.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 8 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0019] Figure 1 A structural diagram of a pull-out sun visor according to an embodiment of the present invention from one perspective; Figure 2 FIG. 2 is a structural diagram of another embodiment of a pull-out sun visor of the present invention from another perspective. Figure 1 and Figure 2 As shown, the pull-out sun visor provided in this embodiment includes: a main support seat 1, a rotating shaft 2, a sunshade body, a makeup mirror 3, a fill light, a telescopic tube 4, a sliding seat 5, a first conductive structure and a second conductive structure, and one end of the rotating shaft 2 is rotatably mounted on the main support seat 1, and the main support seat 1 is mounted on the frame sheet metal. At the same time, the other end of the rotating shaft 2 is extended into the sunshade body, and the main support seat 1 and the rotating shaft 2 are used as carriers for stably mounting the sunshade body on the vehicle, and the arrangement direction of the sunshade body is adjusted by rotating the rotating shaft 2 on the main support seat 1. In addition, the makeup mirror 3 and the fill light are both mounted on the sunshade body, and the circuit board of the fill light is embedded in the sunshade body, so that the makeup mirror 3 and the fill light are integrated and installed on the sunshade body, and modularization is achieved, which is conducive to repair and replacement after damage.

[0020] Specifically, the telescopic tube 4 is installed on the sunshade body along the length direction of the sunshade body, so that the telescopic tube 4 and the sunshade body are an integral structure, which improves the connection stability. At the same time, the slide 5 is slidably set in the telescopic tube 4 and rotatably sleeved on one end of the rotating shaft 2 extending into the sunshade body, so that the slide 5 can move in the telescopic tube 4, changing the position of the slide 5 in the telescopic tube 4, thereby providing conditions for the subsequent adjustment of the position stroke of the sunshade body. In addition, since the slide 5 is rotatably installed on the rotating shaft 2 and the slide 5 is axially limited on the rotating shaft 2, there is only circumferential rotation between the rotating shaft 2 and the slide 5 and no axial movement. The rotation between the slide 5 and the rotating shaft 2 can be used to satisfy the flip adjustment of the sunshade body, while the axial movement limitation between the slide 5 and the rotating shaft 2 can satisfy the sliding of the slide 5 in the telescopic tube 4 to achieve the telescopic purpose of the sunshade body relative to the rotating shaft 2. It can not only meet the use requirements of traditional sun visors, but also achieve an increase in the maximum adjustment stroke. The structure is more flexible, the adaptability is better, and the side shielding effect is better, thereby improving driving comfort and safety.

[0021] Figure 3 FIG. 1 is a schematic diagram of a first conductive structure of a preferred embodiment of the present invention. Figures 1 to 3 As shown, the telescopic tube 4 and the rotating shaft 2 are both made of conductive materials, such as aluminum alloy. At this time, the sliding seat 5 and the telescopic tube 4 are connected by sliding contact, that is, the sliding seat 5 and the telescopic tube 4 can slide relative to each other, and the sliding seat 5 and the telescopic tube 4 can always maintain an electrical connection state, meeting the use requirements of maintaining electrical conduction during the extension and retraction of the sun visor. In addition, the sliding seat 5 and the rotating shaft 2 are insulated from each other to avoid a short circuit between the rotating shaft 2 and the telescopic tube 4. Moreover, the sliding seat 5 and the telescopic tube 4 at this time constitute a first conductive structure to achieve conduction of one of the positive and negative electrodes. In addition, a telescopic contact 6 is provided in the sunshade body, and the telescopic contact 6 abuts against the outer wall of the rotating shaft 2. At this time, the rotating shaft 2 and the telescopic contact 6 constitute a second conductive structure to realize the conduction of the other pole of the positive and negative poles, that is, the telescopic contact 6 always maintains the use requirement of abutting against the rotating shaft 2, which provides conditions for the electrical connection between the telescopic contact 6 and the rotating shaft 2, and also enables the contact state to be maintained when the rotating shaft 2 rotates, meeting the use requirement of maintaining electrical conduction during the expansion and contraction and flipping of the sun visor. In addition, the rotating shaft 2 is a hollow shaft. At this time, a wire is passed through the hollow of the rotating shaft 2 and then electrically connected to the slide seat 5, while the other wire is directly electrically connected to the rotating shaft 2, and the telescopic tube 4 and the telescopic contact 6 are both electrically connected to the circuit board of the fill light, that is, the electrical connection between the circuit board of the fill light and the external power supply is realized through the first conductive structure and the second conductive structure formed, and the electrical conduction state can always be maintained during the flipping and expansion of the sun visor, so as to maintain the normal use of the sun visor. It is worth pointing out that an outer protective cover 21 is provided outside the end of the rotating shaft 2 connected to the main support seat 1, which can not only improve the aesthetics, but also achieve external insulation of the rotating shaft 2 and improve safety in use.

[0022] More specifically, the first conductive structure also includes a sliding contact sheet 51. At this time, the sliding contact sheet 51 is also made of a conductive material, and the sliding contact sheet 51 is an arched spring sheet, so that the sliding contact sheet 51 has good elasticity, which provides conditions for the subsequent close contact with the telescopic tube 4 and meets the relative sliding requirements. In addition, the sliding contact sheet 51 is installed on the slide 5 so that the sliding contact sheet 51 can move with the slide 5. At the same time, the sliding contact sheet 51 is arched toward one side of the telescopic tube 4 and abuts against the inner wall of the telescopic tube 4, so that the sliding contact sheet 51 can always be pressed against the inner wall of the telescopic tube 4 through its own elastic force. When the slide 5 slides relative to the telescopic tube 4, the sliding contact sheet 51 can always contact the inner wall of the telescopic tube 4 and maintain an electrically conductive state. It is worth pointing out that the wire connected to the slide 5 and passed through the hollow of the rotating shaft 2 is connected to the sliding contact sheet 51 to meet the use requirements of connecting to an external power source.

[0023] Figure 4 FIG. 1 is a structural diagram of a telescopic tube according to a preferred embodiment of the present invention. Figures 1 to 4 As shown, the telescopic tube 4 includes an outer tube 41 and an inner sleeve 42. At this time, the outer tube 41 is made of a conductive material, such as aluminum alloy, and the inner sleeve 42 is made of an insulating material, such as plastic. At the same time, the outer tube 41 is sleeved outside the inner sleeve 42, that is, an insulating layer is formed on the inner side of the telescopic tube 4 through the inner sleeve 42. In addition, a avoidance opening is provided on the inner sleeve 42 along its length. At the same time, the slide seat 5 is slidably arranged in the inner sleeve 42, that is, the inner sleeve 42 is used as a sliding guide for the slide seat 5, and the insulation isolation between the outer tube 41 and the rotating shaft 2 is also achieved through the inner sleeve 42 to prevent short circuit problems. In addition, the sliding contact piece 51 on the slide seat 5 is extended into the avoidance opening and abuts against the inner wall of the outer tube 41, that is, while the insulation is met through the inner sleeve 42, the avoidance opening can still provide conditions for the sliding contact piece 51 to contact the inner wall of the outer tube 41.

[0024] Figure 5 FIG. 1 is a structural diagram of a slide seat in a preferred embodiment of the present invention. Figure 3 and Figure 5As shown, the slide 5 itself is also made of insulating material, such as plastic material. In addition, guide feet 52 are provided at both ends of the slide 5, and the two guide feet 52 extend in opposite directions, that is, the two ends of the slide 5 are extended by the two guide feet 52, so that the contact length of the slide 5 in the telescopic tube 4 is longer, thereby improving the stability of the slide 5 when sliding. In addition, each guide foot 52 includes two legs 521, and the two legs 521 of the same guide foot 52 are respectively located on both sides of the slide 5 and the ends are arranged obliquely toward the opposite side, that is, the two legs 521 of the same guide foot 52 are arranged in a trumpet shape, and the guide foot 52 has a certain deformation ability, so that when the slide 5 is installed in the telescopic tube 4, the ends of the two legs 521 arranged obliquely can be pressed against the inner wall of the telescopic tube 4, so that the slide 5 can be reliably installed in the telescopic tube 4, and the deformation of the legs 521 can meet the use requirements of the slide 5 sliding in the telescopic tube 4, and the structural design is more reasonable.

[0025] Figure 6 FIG. 1 is a schematic diagram of the installation of a telescopic contact on a secondary support according to a preferred embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 6 As shown, two sub-supports 7 are also provided on the sunshade body. Preferably, the two sub-supports 7 are embedded in the sunshade body. In addition, the two ends of the telescopic tube 4 are respectively sleeved on the two sub-supports 7, that is, the two ends of the telescopic tube 4 are supported by the two sub-supports 7, ensuring that the telescopic tube 4 can be stably installed on the sunshade body. In addition, the rotating shaft 2 passes through one of the two sub-supports 7 and then extends into the telescopic tube 4, ensuring that the rotating shaft 2 can be smoothly connected to the sliding seat 5 in the telescopic tube 4. In addition, the telescopic contact 6 is provided on the sub-support 7 through which the rotating shaft 2 passes, so that when the rotating shaft 2 is extended and retracted relative to the sunshade body, the rotating shaft 2 is always in a state of passing through the sub-support 7, which provides conditions for maintaining the state of electrical conduction of the second conductive structure in the subsequent process. In addition, the telescopic contact 6 includes a telescopic spring 61 and a conductive contact 62. At this time, a telescopic hole 71 is opened along the radial direction of the rotating shaft 2 on the auxiliary support 7 on which the telescopic contact 6 is installed. During installation, the conductive contact 62 is slidably set at the hole mouth of the telescopic hole 71. At the same time, the telescopic spring 61 is set in the telescopic hole 71 and one end is abutted against the end of the conductive contact 62 located in the telescopic hole 71, and the other end of the conductive contact 62 is abutted against the outer wall of the rotating shaft 2. That is, the auxiliary support 7 provides a carrier for the installation of the telescopic contact 6, and the telescopic contact 6 is pushed by the telescopic spring 61, so that the telescopic contact 6 can always be pressed against the rotating shaft 2, and the contact state can be maintained regardless of the circumferential rotation or axial expansion of the rotating shaft 2, thereby meeting the electrical conduction requirements.

[0026] Figure 7 FIG. 1 is a schematic diagram of a limiting structure of a preferred embodiment of the present invention. Figure 5 and Figure 7As shown, a limiting structure 8 is also provided on the slide 5. At this time, a concave cavity 53 is opened in the middle of the slide 5, and one end of the rotating shaft 2 rotatably connected to the slide 5 is passed through the cavity opening of the concave cavity 53, that is, the rotating shaft 2 is located at the cavity opening of the concave cavity 53. In addition, the limiting structure 8 is arranged in the concave cavity 53, and the concave cavity 53 provides an installation space for the limiting structure 8 to be installed on the slide 5. At the same time, the cooperation between the limiting structure 8 and the rotating shaft 2 realizes the stability of the state of the sunshade body in the closed and opened states, avoiding the problem of accidental movement affecting the use. In addition, the limiting structure 8 includes an elastic pressing member 81, which is pressed against the outer wall of a section of the rotating shaft 2 at the cavity opening of the concave cavity 53, and a limiting plane 22 is arranged along the tangent direction of the outer wall of the portion where the rotating shaft 2 and the elastic pressing member 81 are pressed, that is, when the rotating shaft 2 rotates relative to the slide 5, the elastic pressing member 81 presses against the outer wall of the rotating shaft 2, increasing the friction force of the rotating shaft 2 during relative rotation, and avoiding the problem of accidental rotation after the sun visor is flipped open. When the sun visor is reversely flipped and closed, the limiting plane 22 on the rotating shaft 2 gradually aligns with the elastic pressing member 81 as the rotating shaft 2 rotates. At this time, the elastic pressing member 81 pushes the limiting plane 22 to align the limiting plane 22 with the elastic pressing member 81, and the automatic closing in the closed end state can be realized. At the same time, the cooperation of the limiting plane 22 and the elastic pressing member 81 limits the continued relative rotation of the rotating shaft 2, which plays a role in limiting the sun visor in the closed state, and preventing the sun visor from accidentally opening.

[0027] More specifically, the elastic pressing member 81 includes a pressing plate 811 and a plurality of pressing springs 812. At this time, the pressing plate 811 and the plurality of pressing springs 812 are both arranged in the concave cavity 53, and one side of the pressing plate 811 is pressed against the outer wall of a section of the rotating shaft 2 located at the cavity opening of the concave cavity 53, and the rotating shaft 2 is pressed by the pressing plate 811. At the same time, a plurality of pressing springs 812 are arranged between the other side of the pressing plate 811 and the cavity bottom of the concave cavity 53, that is, the pressing springs 812 are used to apply a force to the pressing plate 811 against the rotating shaft 2, thereby increasing the resistance of the rotating shaft 2 when rotating, thereby maintaining the state of the sunshade body relative to the rotating shaft 2 stable, and at the same time, the pressing plate 811 can cooperate with the limiting plane 22 on the rotating shaft 2 to realize the automatic closing operation in the last closed state and the state restriction after closing.

[0028] More specifically, the position-limiting structure 8 also includes an outer cover. In this case, a cross-section of the outer cover is arranged in a "U" shape. The outer cover is arranged outside the position-limiting structure 8 and a section where the rotating shaft 2 cooperates with the position-limiting structure 8. The outer cover realizes external protection of the position-limiting structure 8 and a part of the rotating shaft 2, which has higher safety and more stable structure. In addition, a guide avoidance groove is provided on the outer cover, and a guide block extending into the guide avoidance groove is provided on the side of the pressing plate 811, which improves the stability of the pressing plate 811 during movement.

[0029] Figure 8FIG. 2 is a cross-sectional view of a buffer assembly according to a preferred embodiment of the present invention. Figure 5 and Figure 8As shown, a buffer assembly 9 is also provided on the slide 5. At this time, the buffer assembly 9 is arranged between the pressure plate 811 and the slide 5, providing conditions for subsequent action on the pressure plate 811. In addition, the buffer assembly 9 includes a first piston 91, a second piston 92 and a return spring 93. During installation, a side groove 54 connected to the concave cavity 53 is provided on the slide 5 and located on one side of the concave cavity 53 along the arrangement direction of the pressing spring 812, so that the length direction of the side groove 54 can be consistent with the expansion and contraction direction of the pressing spring 812, that is, the side groove 54 can adapt to the movement of the pressure plate 811. At this time, a first pressure chamber 55 extending in the same direction is provided on the groove wall of the side groove 54 close to the rotating shaft 2. At the same time, an extension portion is provided on the outer side wall of one end of the slide 5 where the side groove 54 is provided and along the axial direction of the rotating shaft 2, and the installation space of the slide 5 is expanded by the extension portion. In addition, a second pressure chamber 56 is provided in the extension portion, and a throttle hole 57 is provided between the second pressure chamber 56 and the first pressure chamber 55, that is, the first pressure chamber 55 and the second pressure chamber 56 are connected through the throttle hole 57. In addition, the cross-sectional area of ​​the throttle hole 57 is set to be smaller than the cross-sectional area of ​​the first pressure chamber 55 and the second pressure chamber 56, so that the fluid between the first pressure chamber 55 and the second pressure chamber 56 needs to pass through the throttle hole 57 with a smaller cross-section when moving relative to each other, thereby limiting the flow rate and achieving buffering. In addition, an end cover 58 is provided at one end of the second pressure chamber 56 away from the throttle hole 57, and a vent hole 581 connected to the outside is provided on the end cover 58, so that the second pressure chamber 56 can be connected to the outside through the vent hole 581 on the end cover 58, which provides conditions for the subsequent free movement of the second piston 92 in the second pressure chamber 56. During installation, the first piston 91 and the second piston 92 are slidably disposed in the first pressure chamber 55 and the second pressure chamber 56 respectively, the second piston 92 is located on the side of the end cover 58 close to the throttle hole 57, the two ends of the return spring 93 are respectively abutted between the second piston 92 and the end cover 58, and the first pressure chamber 55 and the second pressure chamber 56 and between the first piston 91 and the second piston 92 are filled with pressure oil, so that the pressure oil serves as a medium for pressure transmission. In addition, one end of the first piston 91 is extended from the cavity mouth of the first pressure chamber 55 to the side groove 54, and one end of the pressure plate 811 is extended to the side groove 54. When the pressure plate 811 moves toward the side of the rotating shaft 2, the end of the pressure plate 811 contacts the end of the first piston 91 extending into the side groove 54, so that the first piston 91 can cooperate with the pressure plate 811, thereby limiting the problem of the rotating shaft 2 rotating rapidly due to the rapid pushing of the limiting plane 22 when the pressure plate 811 is aligned with the limiting plane 22, thereby avoiding the problem of the sunshade body quickly hitting the roof due to the rapid rotation of the rotating shaft 2, and achieving buffering when the sunshade is automatically closed in the final closed state, and the protection effect is better.In addition, a retaining ring is provided at the cavity opening of the first pressure chamber 55 near one end connected to the side groove 54, the end of the first piston 91 extending into the side groove 54 is a variable cross-section end, and the cross-section of the end of the first piston 91 located in the first pressure chamber 55 is larger than the cross-section of the end extending into the side groove 54. By sleeve-arranging the retaining ring on the end of the first piston 91 extending into the side groove 54 and clamping it at the cavity opening of the first pressure chamber 55, the first piston 91 can be prevented from escaping from the first pressure chamber 55, thereby improving the structural stability. It is worth pointing out that when the pressure plate 811 just moves to the area where the limiting plane 22 of the rotating shaft 2 is located, the pressure plate 811 just contacts the first piston 91 and pushes the first piston 91. At this time, the first piston 91 pushes the pressure oil in the first pressure chamber 55 to flow to the second pressure chamber 56 through the throttle hole 57, and squeezes the second piston 92 to compress the return spring 93. In addition, since the cross-sectional area of ​​the throttle hole 57 is smaller than that of the first pressure chamber 55 and the second pressure chamber 56, the flow rate of the pressure oil through the throttle hole 57 is limited, so as to meet the use requirement of limiting the slow movement of the first piston 91, so that the pressure plate 811 can slowly push the limiting plane 2 2, thereby avoiding the problem of the sunshade body hitting the roof too quickly when it is flipped into place, and meeting the use requirement of closing buffer. In addition, when the sunshade body is flipped back and opened, the pressure plate 811 is offset from the limit plane 22 to other areas of the shaft 2, so that the pressure plate 811 is pushed in the opposite direction, thereby separating the pressure plate 811 from the first piston 91, so that the return spring 93 can squeeze the pressure oil into the first pressure chamber 55 through the second piston 92, thereby pushing the first piston 91 in the opposite direction into the side groove 54, realizing the reset of the first piston 91, and providing buffer when waiting for the sunshade body to be flipped back and closed into place again, meeting the requirement of repeated use.

[0030] More specifically, the buffer assembly 9 also includes a quick reset channel 59, which is also arranged in the slide seat 5, and is arranged in parallel beside the throttle hole 57. At the same time, the two ends of the quick reset channel 59 are also connected to the first pressure chamber 55 and the second pressure chamber 56, that is, the quick reset channel 59 and the throttle hole 57 are in parallel with each other. In addition, an expansion activity chamber 591 is arranged in the middle of the quick reset channel 59, and the space in the middle of the quick reset channel 59 is increased by expanding the activity chamber 591, which provides conditions for the subsequent installation and movement of the pressure ball 5911 and the tightening spring 812. During installation, a pressure ball 5911 and a push spring 5912 are arranged in the expanded activity chamber 591, and the push spring 5912 is arranged on the side of the pressure ball 5911 close to the first pressure chamber 55, and the two ends of the push spring 5912 are respectively abutted against the pressure ball 5911 and the cavity wall of the expanded activity chamber 591, so that the push spring 812 and the pressure ball 5911 can form a one-way valve structure, that is, the pressure oil can flow from the second pressure chamber 56 to the first pressure chamber 55 through the quick reset channel 59, while the pressure oil in the first pressure chamber 55 cannot flow to the second pressure chamber 56 through the quick reset channel 59, that is, during buffering, only the throttle hole 57 is used to supply the pressure oil flow, and during resetting, the pressure oil is supplied through the throttle hole 57 and the quick reset channel 59 together, so that rapid resetting can be achieved while ensuring the buffering effect, meeting the requirement that the sun visor can be used quickly again.

[0031] More specifically, the expanded activity cavity 591 in the middle of the quick reset channel 59 also has a cavity opening connected to the outside. At this time, a sealing plug 5913 is also provided in the cavity opening of the expanded activity cavity 591. The sealing plug 5913 opens or closes the cavity opening of the expanded activity cavity 591, which facilitates the installation and replacement of the pressure ball 5911 and the push spring 5912, and the structural design is more reasonable.

In addition, the slide seat 5 and the telescopic tube 4 constitute a first conductive structure, a telescopic contact 6 is arranged on the sun visor body and abuts against the outer wall of the rotating shaft 2 to constitute a second conductive structure, which can always maintain an electrically conductive state when the sun visor is flipped and pulled out, ensuring that the sun visor can ensure the normal use of its functions in any state.
