Description

Technical Field

[0001] The utility model relates to the field of vehicle accessories, in particular to a multifunctional demisting device. Background Art

[0002] There are two conditions for fogging of car windows: one is too high humidity and the other is too low temperature. Both are indispensable. One is that when the air humidity is constant and the window temperature is lower than the dew point temperature, condensation will form on the window surface, which is the fogging phenomenon of the windshield that we often see; the other is that when there is a certain temperature difference on both sides of the window, the saturated vapor pressure of the water on the low temperature surface is lower than the vapor pressure of the surrounding environment, the water vapor will gather on the glass surface and seep out in the form of tiny water droplets to form fog.

[0003] At present, car windows are usually defogged by turning on the air conditioner or opening the window to balance the temperature difference between the inside and outside of the car, or wiping it with a rag. However, for buses, coaches or other public transportation, passengers cannot turn on the air conditioner, and in rainy and snowy weather, they cannot open the window to balance the temperature difference between the inside and outside of the car. At this time, they can only wipe it with hands or paper towels, which is not only inconvenient but also unhygienic.

[0004] The erasing device in the prior art can usually only complete the function of wiping liquid from the surface of an object. For the use environment of a vehicle, not only is the space inside the vehicle limited, but the storage of the erasing device is also a challenge. In addition, the vehicle will face a variety of uncontrollable risks during use. For example, in an emergency, the occupants of the vehicle cannot open the door or window, which may cause a dangerous situation. Therefore, how to take into account the use environment of the vehicle and realize the multifunctional use of the defogger is a problem we need to consider. Utility Model Content

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0037] The following is a further detailed description of the embodiments of the multifunctional demisting device of the present invention in conjunction with the accompanying drawings.

[0038] like Figure 1 As shown, the present application provides a multifunctional defogger, including a wiping plate 1 and a connecting member 2. The connecting member 2 is detachably connected to the wiping plate 1. When the wiping plate 1 is installed on the connecting member 2, functions such as wiping glass can be realized. When the wiping plate 1 is removed, the connecting member 2 can be used as an independent window breaker.

[0039] Specifically, the wiper 1 is used to wipe off liquids; the connecting member 2 includes a cross bar 21 and a longitudinal bar 22 connected to each other, the cross bar 21 is detachably connected to the wiper 1, and a window-breaking nail 4 is provided at the end of the cross bar 21.

[0040] In this example, the axes of the horizontal bar 21 and the vertical bar 22 are perpendicular to each other, and a window-breaking nail 4 is provided at the end of the horizontal bar 21, so that in an emergency, the connecting piece 2 and the wiper plate 1 can be removed, the vertical bar 22 can be held, and the window can be knocked with the window-breaking nail 4.

[0041] Since the window breaking nail 4 is arranged on the connecting member 2, the connecting member 2 is detachably connected to the wiping plate 1, thereby realizing the multifunctional use of wiping and breaking windows. It is not only simple to operate and suitable for the use environment in the vehicle, but also improves the safety of the vehicle in emergency situations compared with a separate device for wiping off fog.

[0042] In some optional embodiments, the wiper plate 1 includes a connecting plate 11 and a water absorbent pad 12 , one side of the connecting plate 11 is detachably connected to the water absorbent pad 12 , and the other side of the connecting plate 11 is detachably connected to the cross bar 21 .

[0043] Optionally, the absorbent pad 12 is made of a sponge and has the same shape as the connecting plate 11 , thereby completely covering one side of the connecting plate 11 to improve wiping efficiency.

[0044] Furthermore, a barb layer is provided on one side of the connecting plate 11, and a fluff layer is provided on one side of the absorbent pad 12. The barb layer of the connecting plate 11 is pasted to the fluff layer on one side of the absorbent pad 12, so that the absorbent pad 12 and the connecting plate 11 can be detachably connected, which is convenient for cleaning and replacement of the absorbent pad 12.

[0045] In some optional embodiments, such as Figure 2 As shown, the above-mentioned connecting plate 11 is detachably connected to the above-mentioned cross bar 21 through a connecting assembly, and the above-mentioned connecting assembly includes a rotating connecting piece 13 and a clamping piece 14. The rotating connecting piece 13 is connected to the above-mentioned connecting plate 11. On the above-mentioned rotating connecting piece 13, a mounting hole is opened in a direction parallel to the above-mentioned connecting plate 11, and the end of the above-mentioned cross bar 21 provided with a window breaking nail 4 is rotatably connected to the above-mentioned mounting hole; the clamping piece 14 is arranged on the above-mentioned connecting plate 11 at intervals from the above-mentioned rotating connecting piece 13, and a U-shaped groove is opened on the above-mentioned clamping piece 14, and the opening direction of the above-mentioned U-shaped groove is away from the above-mentioned connecting plate 11, and the other end of the above-mentioned cross bar 21 away from the above-mentioned window breaking nail 4 is rotatably connected to the above-mentioned U-shaped groove.

[0046] It can be understood that when installing the cross bar 21 and the connecting plate 11, first insert one end of the cross bar 21 provided with the window breaking nail 4 into the installation hole, and then clamp the other end of the cross bar 21 away from the window breaking nail 4 into the U-shaped groove from the opening of the U-shaped groove.

[0047] The advantage of such a configuration is that the rotating connector 13 and the clamping member 14 are respectively rotatably connected to the two ends of the cross bar 21, and the axial displacement of the cross bar 21 is also limited. While ensuring the connection stability between the cross bar 21 and the connecting plate 11, the installation and disassembly of the cross bar 21 and the connecting plate 11 are also facilitated.

[0048] In other embodiments, a clamping member 14 may be provided separately to be clamped with the middle portion of the cross bar 21 .

[0049] In some optional embodiments, such as Figure 3As shown, the above-mentioned cross bar 21 includes a main body 212, a rotating part 213 and a clamping part 214. The middle part of the main body 212 is connected to the above-mentioned longitudinal bar 22; the rotating part 213 is connected to one end of the above-mentioned main body 212, and its diameter is smaller than the diameter of the main body 212. The above-mentioned window-breaking nail 4 is connected to the end of the above-mentioned rotating part 213 away from the main body 212, and the above-mentioned rotating part 213 is adapted to the size of the above-mentioned mounting hole; the clamping part 214 is connected to the other end of the above-mentioned main body 212, and its diameter is smaller than the diameter of the above-mentioned main body 212, and the above-mentioned clamping part 214 is adapted to the size of the above-mentioned U-shaped groove.

[0050] It can be understood that the main body 212 is a cylinder, and the rotating part 213 and the clamping part 214 are also cylinders, but their diameters are smaller than the diameter of the main body 212, so that when the cross bar 21 is connected with the rotating connector 13 and the clamping part 14, the rotating part 213 and the clamping part 214 are respectively located in the mounting hole and the U-shaped groove, while the main body 212 is against the rotating connector 13 and the clamping part 14. In this way, during installation, the installation accuracy and the stability of the cross bar 21 after installation are improved.

[0051] In this example, when the rotating portion 213 is installed in the installation hole, the window breaking nail 4 is also located in the installation hole, which also plays a protective role for the window breaking nail 4.

[0052] In some optional embodiments, such as Figure 4 As shown, the multifunctional defogger device further comprises a telescopic member 3, the telescopic member 3 comprises an inner rod 31, an outer rod 32 and a locking member 33, one end of the inner rod 31 is connected to one end of the longitudinal rod 22 away from the transverse rod 21; the outer rod 32 is sleeved outside the inner rod 31 and can slide along the axial direction of the inner rod 31; the locking member 33 is connected to the outer rod 32, when the locking member 33 is in a first state, the inner rod 31 and the outer rod 32 can slide relative to each other, and when the locking member 33 is in a second state, the relative positions of the inner rod 31 and the outer rod 32 are fixed.

[0053] It can be understood that the function of the telescopic member 3 is to adjust the wiping range of the wiping plate 1, and of course, it can also adjust the window breaking range of the window breaking nail 4. By adjusting the state of the locking member 33, the outer rod 32 and the inner rod 31 can be slid and locked.

[0054] For example, when the locking member 33 is a latch, the latch is inserted into the through holes of the inner rod 31 and the outer rod 32 at the same time, which is the second state, and the inner rod 31 and the outer rod 32 are locked. The latch is pulled out from the through holes of the inner rod 31 and / or the outer rod 32, which is the first state, and the inner rod 31 and the outer rod 32 can slide relative to each other to adjust the overlapping length of the two.

[0055] In this example, the locking member 33 is a rotating sleeve, and its inner wall is provided with an inclined surface inclined toward the axial direction, and an internal thread is provided on the inclined surface. The outer rod 32 is sleeved on the end of the inner rod 31, and a plurality of support plates extending along the axial direction are circumferentially spaced, and an external thread is provided on the support plate. When the internal thread cooperates with the external thread and bites tightly, the locking member 33 is in the second state, and the inclined surface pushes the support plate to hold the inner rod 31 inward.

[0056] It can be understood that the above-mentioned inclined surface gradually shrinks inward from the end of the support piece away from the outer rod 32 to the end close to the outer rod 32. When the rotating sleeve moves toward the support piece, due to the bite fit of the internal thread and the external thread, the inclined surface pushes all the support pieces to shrink toward the axis to hold the inner rod 31 tightly, thereby achieving the fixation of the inner rod 31 and the outer rod 32. At this time, the rotating sleeve approaches the support piece, which is the second state of the locking member 33; when the rotating sleeve moves away from the support piece, the inclined surface loosens the support piece, so that the outer rod 32 no longer holds the inner rod 31 tightly, and the inner rod 31 and the outer rod 32 can slide against each other. At this time, the rotating sleeve is away from the support piece, which is the first state of the locking member 33.

[0057] Preferably, the surface of the rotating sleeve is provided with axial grooves to increase the friction force during rotation.

[0058] In some optional embodiments, the outer rod 32 is provided with a gripping sleeve 321 made of soft material.

[0059] For example, materials such as sponge or rubber are used and an integral molding method is adopted during production. An annular groove can be provided on the surface to increase the friction when holding.

[0060] In some optional embodiments, a hanging member 322 is provided at the end of the outer rod 32 away from the inner rod 31 , which is rotatably connected to the outer rod 32 and has a through hole for hanging.

[0061] It can be understood that by using the hanging member 322, the device can be conveniently hung on a hook for easy access at any time.

[0062] In some optional embodiments, the longitudinal rod 22 includes a connecting portion 221 and a transition portion 222 which are connected in sequence, and the transition portion 222 has a curved line for avoiding the wiping board 1 when the wiping board 1 rotates relative to the connecting member 2 .

[0063] In this example, the wiping board 1 and the telescopic member 3 are located in different planes through the transition portion 222, which is not only more conducive to applying force when wiping off water mist, but also provides a larger rotation range angle for the wiping board 1 when the wiping board 1 rotates.

[0064] In some optional embodiments, the transition portion 222 is provided with a plug hole 223 along the axial direction, the side wall of the transition portion 222 is provided with a snap-in hole 224 connected to the plug hole 223, and a ball spring 34 is provided on the telescopic member 3, and the ball spring 34 is snap-connected with the snap-in hole 224 so that the telescopic member 3 and the longitudinal rod 22 can be detachably connected.

[0065] It can be understood that the detachable connection between the telescopic member 3 and the longitudinal rod 22 is achieved through the extension and retraction of the ball spring 34. Preferably, on the inner wall of the transition portion 222, a sliding groove connected to the snap-in hole 224 is axially opened from the opening of the plug-in hole 223, and the sliding groove is slidably matched with the ball of the ball spring 34, thereby providing a guiding effect when the ball spring 34 is snapped into or separated from the snap-in hole 224.

[0066] In this example, two clamping holes 224 are symmetrically arranged along the radial direction, and two ball springs 34 are also arranged correspondingly, and the purpose of such arrangement is to improve the connection stability between the telescopic member 3 and the longitudinal rod 22. Based on this, the ball spring 34 can also be a V-shaped clamping member, and the two ends of the opening are respectively clamped with the two clamping holes 224, and the clamping holes 224 are separated by pressing the two ends of the V-shaped clamping member.

[0067] The working principle of the embodiment of the present application is: rotate the locking member 33 to the first state, adjust the inner rod 31 and the outer rod 32 to reach the required length, then rotate the locking member to the second state, fix the required length, and use the wiper 1 to wipe the water mist on the car window, rearview mirror or car body surface. When encountering an emergency, press the spring ball and separate the telescopic member 3 from the connecting member 2, and then separate the connecting member 2 from the wiper 1, then hold the longitudinal rod 22, and use the window-breaking nail 4 at the end of the crossbar 21 to smash the window.

[0068] The multifunctional defogger of the present application is characterized in that the wiper plate 1 is detachably connected to the connector 2, and a window-breaking nail 4 is arranged at the end of the cross bar 21 of the connector 2, so that in an emergency, the connector 2 and the wiper plate 1 can be removed, the longitudinal bar 22 can be held, and the window-breaking nail 4 can be used to knock on the vehicle window, thereby realizing the multifunctional purpose of wiping and breaking the window. The operation is not only simple, but also suitable for the use environment in the vehicle. Compared with a separate demisting device, the safety of the vehicle in an emergency is also improved. The rotating connector 13 and the clamping member 14 are respectively connected to the cross bar 2 The two ends of 1 are rotatably connected, and the axial displacement of the cross bar 21 is also limited. While ensuring the connection stability between the cross bar 21 and the connecting plate 11, it is also convenient for the installation and disassembly of the cross bar 21 and the connecting plate 11; by setting the telescopic member 3, the wiping range of the wiping plate 1 and the window breaking range of the window breaking nail 4 can be adjusted; by making the transition portion 222 have a curved line, the wiping plate 1 and the telescopic member 3 are located in different planes, which is not only more conducive to applying force when wiping water mist, but also provides a larger rotation range angle for the wiping plate 1 when the wiping plate 1 rotates.
