Description

Technical Field

[0001] The present application relates to the field of automobile interior decoration, and in particular to an automobile sun visor with a sliding cover structure. Background Art

[0002] The car sun visor is a board installed above the front passenger seat of the car to prevent the sun from interfering with the vision. It is folded up to fit the car body when not in use and folded down to block the sun when in use. As customers' requirements for sun visors continue to increase, multifunctional sun visors are increasingly favored by consumers. As the functions of sun visors increase, new problems arise.

[0003] The technical solution provided by the present application is aimed at improving the existing sun visor with a sliding cover structure. The basic structure of the existing product is that a makeup mirror is arranged on the sun visor, a dustproof sliding cover is arranged on the makeup mirror, and a mirror front light is arranged around the makeup mirror. The mirror front light adopts a mechanical trigger switch, and the reciprocating movement of the sliding cover triggers the switch state of the mirror front light.

[0004] The inventors found that the existing products have the following deficiencies:

[0005] On the one hand, after using the sun visor, the user may forget to reset the sliding cover and fail to turn off the mirror light in time; and when the sun visor is folded back, it will fit against the car body, and the lighting status of the mirror light cannot be detected, causing the mirror light to remain on, which not only causes energy waste but also poses certain safety hazards.

[0006] Secondly, the mirror headlight uses a mechanical trigger switch, which may cause circuit deformation and failure due to impact and wear after repeated use, and has a short service life. In addition, the mechanical switch will produce a reaction force on the sliding cover, which will make the user feel the change in opening force and affect the overall texture of the product.

[0048] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present application. Specifically, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present invention.

[0049] It should be noted that similar reference numerals and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0050] like Figure 1-5 As shown, Figure 4 , Figure 5The range enclosed by the position B is the eccentric magnetic field range. As mentioned in the background technology, in view of the problems in the prior art, this embodiment provides a car sun visor with a sliding cover structure. The sun visor is provided with a sliding cover 1, and a makeup mirror 2 is provided below the sliding cover 1. The periphery of the makeup mirror 2 is provided with a mirror front light 3 to avoid unclear colors of the mirror image, including a first switch and a second switch, and the two switches jointly control the lighting state of the mirror front light 3. The first switch controls the on-off of the circuit by detecting the use state of the sun visor. When the sun visor is flipped down for use, the first switch is connected; when the sun visor is flipped up and retracted, the first switch is disconnected; to prevent the mirror front light 3 from remaining in the lighting state when the sun visor is retracted. The second switch controls the on-off of the circuit by detecting the relative position relationship of the sliding cover 1 relative to the vanity mirror 2. When the sliding cover 1 blocks the vanity mirror 2, the second switch remains in an off state; when the sliding cover 1 slides away from the vanity mirror 2, the second switch closes and connects the circuit; when the user only needs to use the sun visor to block light, the user can keep the sliding cover 1 covering the vanity mirror 2 to avoid the mirror lamp 3 from lighting up and providing unnecessary lighting. The first switch and the second switch are both connected in series with the mirror lamp 3; only when the two switches are connected at the same time, the circuit of the mirror lamp 3 is connected.

[0051] Compared with the prior art, the automobile sun visor with a sliding cover structure provided by the present invention is equipped with a first switch and a second switch to perform dual monitoring on the lighting state of the front mirror lamp 3, thereby effectively solving the technical problem in the prior art that the front mirror lamp 3 cannot be turned off in time after the sun visor is folded back.

[0052] In a preferred embodiment, the first switch and the second switch adopt magnetic control switches, and magnets are arranged on the slide cover 1 and the sun visor; when in use, the orientation of the magnet is changed by the slide cover 1 and the sun visor, and the strength of the magnetic field generated by the magnet in the area where the magnetic control switch is located changes; then, the magnetic control switch recognizes the use status of the slide cover 1 and the sun visor to adjust the on and off of the circuit. Compared with mechanical switches, the use of magnetic control switches, on the one hand, does not require mechanical impact to switch the open and closed states of the switch, avoids circuit wear and deformation, and increases the service life of the product; secondly, there is no mechanical impact during use, and there is no jamming in the sliding process of the slide cover 1 and the sun visor, which is smoother during use and has a better overall texture of the product.

[0053] Specifically, the first switch includes a first magnet 41 and a first magnetically controlled switch 42;

[0054] A first magnet 41, which is fixedly connected to the body of the vehicle and is used to generate a magnetic field;

[0055] The first magnetically controlled switch 42 is fixedly connected to the sun visor, and changes the on-off state of the circuit by sensing the change in the strength of the magnetic field generated by the first magnet 41.

[0056] The first magnetic control switch 42 is a normally open switch; when the sun visor is in the folded state, the first magnetic control switch 42 deviates from the magnetic field generated by the first magnet 41, and the first magnetic control switch 42 is in the disconnected state. In the process of unfolding the sun visor, the relative position of the first magnetic control switch 42 and the first magnet 41 changes. When the first magnetic control switch 42 enters the magnetic field range of the first magnet 41, the first magnetic control switch 42 remains in the closed state; on the contrary, when the sun visor is retracted, the first magnetic control switch 42 is out of the magnetic field range of the first magnet 41, and the first magnetic control switch 42 remains in the disconnected state.

[0057] Specifically, the second switch includes a second magnet 61 and a second magnetically controlled switch 62;

[0058] A second magnet 61, which is fixedly connected to the sliding cover 1 and is used to generate a magnetic field;

[0059] The second magnetic control switch 62 is fixedly connected to the sun visor, and changes the on-off state of the circuit by sensing the change in the strength of the magnetic field generated by the second magnet 61. The second magnetic control switch 62 is a normally closed switch; when the slide cover 1 is closed, the magnetic field generated by the second magnet 61 covers the second magnetic control switch 62, and the second magnetic control switch 62 is in an off state.

[0060] The slide cover 1 is opened and pushed to slide. After the second magnet 61 moves away from the second magnetic control switch 62, the magnetic field generated by the second magnet 61 moves away from the second magnetic control switch 62, and the second magnetic control switch 62 switches to a closed state.

[0061] In a preferred embodiment, a connecting member is provided between the sun visor and the vehicle body, and the connecting member includes: a connecting seat 51, the connecting seat 51 adopts a screw cover plate to improve the appearance quality, and the connecting seat 51 is detachably connected to the vehicle body; a rotating shaft 53, one end of which is rotatably connected to the connecting seat 51; an axle tube 52, which is sleeved with the rotating shaft 53, one end of the axle tube 52 away from the connection 51 protrudes from the rotating shaft 53, and one end of the axle tube 52 protruding from the rotating shaft 53 is rotatably connected to the sun visor;

[0062] In the initial state, the rotating shaft 53 is located at one side of the sun visor, and the extension direction of the rotating shaft 53 is the same as the extension direction of the sun visor.

[0063] The first magnet 41 is fixedly arranged on the rotating shaft 53, and the magnetic field generated by the first magnet 41 is an eccentric magnetic field; the first magnetic control switch 42 is fixedly arranged on the side of the sun visor close to the rotating shaft 53, and the positions of the first magnetic control switch 42 and the first magnet 41 correspond to each other; when the sun visor is folded, the first magnetic control switch 42 deviates from the eccentric magnetic field generated by the first magnet 41, and the first magnetic control switch 42 is in an off state; when the sun visor is unfolded, the sun visor and the rotating shaft 53 rotate relative to each other, and the first magnetic control switch 42 moves to the coverage range of the eccentric magnetic field generated by the first magnet 41, and the first magnetic control switch 42 is closed. In addition, the first magnetic control switch 42 may be fixedly installed on the shaft tube 52.

[0064] In the use state 1, the sun visor only rotates circumferentially relative to the rotating shaft 53, and the sun visor is deployed to block the sunlight at the front window of the cockpit. During the deployment of the sun visor, the first magnetic control switch 42 on the first sun visor is moved to the coverage range of the eccentric magnetic field of the first magnet 41, and the first magnetic control switch 42 is switched to the closed state.

[0065] In the use state 2, the rotating shaft 53 is now folded open relative to the cab body, and the sun visor moves circumferentially relative to the rotating shaft 53. The unfolded sun visor is used to block the sunlight at the side window of the cockpit. In the process of unfolding the sun visor, the first magnetic control switch 42 on the first sun visor is moved to the coverage range of the eccentric magnetic field of the first magnet 41, and the first magnetic control switch 42 is switched to the closed state. At this time, the first magnet 41 is set at the end away from the connecting seat 51, and the magnetic field generated by the first magnet 41 can cover the first magnetic control switch 42 on the unfolded sun visor.

[0066] When there is no need to shade the side windows of the cab, the installation can be carried out in a manner that the rotating shaft 53 is fixedly connected to the connecting seat 51, and the shaft tube 52 is fixedly connected to the sun visor.

[0067] By detecting the relative angle between the shaft tube 52 in the connection between the sun visor and the vehicle body and the sun visor, the flipping and using state of the sun visor can be determined, and the detection target is more specific and clear. Before and after the sun visor is flipped, its position relative to the rotating shaft 53 changes significantly. The first magnetic control switch 42 and the first magnet 41 are respectively arranged on the sun visor and the rotating shaft 53, so as to facilitate driving the first magnetic control switch 42 to enter / move away from the eccentric magnetic field range of the first magnet 41; providing accurate switching instructions for the first magnetic control switch 42 can effectively ensure that the first magnetic control switch 42 has a stable working state.

[0068] Specifically, when manufacturing the rotating shaft 53 , the first magnet 41 needs to be pre-embedded in the injection mold in advance, and the first magnet 41 and the rotating shaft 53 are injection molded together to ensure that the first magnet 41 is tightly embedded in the designed position on the rotating shaft 53 .

[0069] Specifically, the first magnet 41 is a C-shaped magnet with a C-shaped cross section, and the central axis of the C-shaped magnet is coaxial with the central axis of the rotating shaft 53. The C-shaped magnet is a sheet magnet with a C-shaped cross section, which generates a stable eccentric magnetic field; in addition, the shape of the C-shaped magnet itself is more consistent with the cylindrical rotating shaft 53, and the overall structure of the embedded connection between the two is more compact and neat.

[0070] Specifically, the second magnet 61 is a cylindrical circular magnet, and the magnetic field generated by the circular magnet is regular and uniform, which is used to affect the opening and closing state of the second magnetic control switch 62, and its operation effect is more stable. When the sliding cover 1 is completely closed, the second magnetic control switch 62 is located on the extension line of the cylindrical axis of the circular magnet, and the second magnetic control switch 62 is located at the center of the magnetic field generated by the second magnet 61.

[0071] Specifically, when the slide cover 1 is produced, the circular magnet is embedded in the injection mold in advance to ensure that the circular magnet can be tightly embedded in the designed position on the slide cover 1 .

[0072] In a preferred embodiment, the first switch may optionally but is not limited to a distance measuring sensor, a processor and an electric control switch. The distance measuring sensor is arranged on the sun visor to detect the distance between the sun visor and the vehicle body and transmit the detected data to the processor. When the detected data is less than a predetermined value, the processor controls the electric switch to remain in an off state to prevent the mirror headlight 3 from maintaining an illuminated state when the sun visor is folded.

[0073] In a preferred embodiment, the first switch includes a third magnetic induction switch, the second switch includes a fourth magnetic induction switch, and a third magnet is fixedly disposed on the sun visor.

[0074] The third magnetic switch is a normally closed switch, and the corresponding third magnet is set on the vehicle body frame. When the sun visor is folded, the third magnetic switch and the third magnet are opposite to each other, and the magnetic field generated by the third magnet covers the third magnetic switch, and the third magnetic switch remains in an open state; when the sun visor is opened, the third magnet is away from the third magnetic switch, and the magnetic field of the third magnet no longer covers the third magnetic switch, and the third magnetic switch switches to a closed state. On the contrary, when the sun visor is folded and retracted, the third magnet approaches the third magnetic switch, and the third magnetic switch switches to an open state.

[0075] The fourth magnetic induction switch is a normally closed switch, and the corresponding three magnets are set on the sliding cover 1. When the sliding cover 1 covers the makeup mirror 2, the fourth magnetic induction switch is opposite to the third magnet, and the magnetic field generated by the third magnet covers the fourth magnetic induction switch, and the fourth magnetic induction switch remains in an open state; when the sliding cover 1 is slid away to reveal the makeup mirror 2, the fourth magnetic induction switch is away from the third magnet, the fourth magnetic induction switch is separated from the magnetic field of the fourth magnet, and the fourth switch is switched to a closed state. On the contrary, when the sliding cover 1 is slid to cover the exposed makeup mirror 2, the fourth magnetic induction cover is close to the third magnet, and the fourth magnetic induction switch is switched to an open state.

[0076] By adopting the method that the third magnetic induction switch and the fourth magnetic induction switch share the third magnet, the overall structure is simpler and the production cost is lower.

[0077] This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only used to help understand the method and its core ideas of this application. The above is only the preferred implementation method of this application. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of this application.
