Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile window defogging, in particular to an outer side defogging device for a front side window glass of an automobile. Background Art
[0002] The clarity of the front side windows of a car is of vital importance for the driver to observe the driving environment. The driver often needs to observe the image in the rearview mirror through the front side windows during driving to ensure safe driving. When there is a large temperature difference between the inside and outside of the car or on rainy days, water mist or water droplets often form on the outside of the window glass, making it impossible for the driver to see the images on both sides of the car and in the rearview mirror through the front side windows, and thus unable to perceive the conditions on both sides and behind the vehicle, which has a great impact on driving safety and is extremely harmful. Therefore, in this case, it is necessary to defog the outside of the front side windows of the car.
[0003] At present, most cars are not equipped with corresponding side window defoggers during design and manufacturing. There are three main defogger methods: one is to stop and wipe, but this method will generate new water mist during low-speed driving, and the water mist can never be removed. Frequent stopping and wiping also poses a great safety hazard; the second is to lower the window glass and then raise it, and use the rubber strips of the window to scrape off the water mist, but due to the certain gap between the rubber strips and the window, this method hardly works; the third is to buy a wiper rubber strip and embed it into the original window rubber strip, but this method makes the wiper rubber strip and the window glass always in contact, which will increase the resistance of the elevator during the glass lifting process, increase power consumption, damage the elevator, and have poor durability, need to be replaced frequently, and have poor practicality. In the prior art, some engineers have designed wipers installed on the outside of the front side windows, but this method not only increases the wind resistance of the car, but also seriously affects the beauty of the car, and also has the disadvantage of poor practicality, and was gradually eliminated later.

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Example
[0026] like Figure 1-4 As shown, a defogger device for the outside of the front side window glass of an automobile comprises two wiper devices and a control system. The two wiper devices are respectively installed in the two front doors of the automobile and are respectively located at the lower outside of the two front side windows. The size of the wiper device can be limited according to actual needs. For example, by limiting the size, the defogger area of the wiper device is limited to the front half of the front side window glass of the automobile. The driver can observe the complete picture of the exterior rearview mirrors on both sides through this area without the need to defog the entire glass.
[0027] The wiper device includes a mounting seat 1 and a wiper strip 2. The mounting seat 1 is arranged in the front door and connected to the wiper strip 2 through a driving device. The wiper strip 2 faces the glass of the front side window. The driving device is used to drive the wiper strip 2 to be close to or away from the glass of the front side window. Preferably, when the wiper strip 2 leaves the glass of the front side window, the distance from the glass is 2-4 mm. In this embodiment, the distance is 3 mm.
[0028] When defogger is needed, the driving device is activated to push the wiper strip 2 to contact the front side window glass and closely adhere to the surface of the front side window glass. Then, combined with the lifting operation of the front side window glass, the water mist on the surface of the front side window glass can be removed to ensure that the front side window glass has a high clarity. When the defogger operation is completed, the driving device is activated to make the wiper strip 2 leave the front side window glass and not contact the front side window glass, so that the resistance of the front window glass lifter is not increased, avoiding the problem that the front window glass lifter is easily damaged due to the wiper strip 2 always contacting the side window glass.
[0029] Among them, the specific structure of the wiper device is as follows:
[0030] The mounting seat 1 is a long strip-shaped plate-like structure, both ends of which are vertically connected to sliding guide rods 6, and the ends of the sliding guide rods 6 away from the mounting seat 1 are provided with limit blocks, and the two ends of the wiper strip 2 are respectively movably sleeved on the two sliding guide rods 6, and the two sliding guide rods 6 are sleeved with return springs 7, and the return springs 7 are located between the limit blocks and the wiper strip 2. Two connecting ears 8 are arranged at intervals in the middle of the mounting seat 1, and the connecting ears 8 are provided with bolt mounting holes 9. The mounting seat 1 is installed in the front door through the two connecting ears 8 and the fixing bolts.
[0031] The wiper strip 2 includes a support plate 10 and a wiper rubber strip 13. A connection seat 11 is provided at both ends of the support plate 10. The connection seat 11 is provided with a guide hole 12 and is slidably connected to the sliding guide rod 6 through the guide hole 12. The thickness of both ends of the support plate 10 is not less than 4 mm. The wiper rubber strip 13 is arranged on a side of the support plate 10 away from the mounting seat 1. In this embodiment, the wiper rubber strip 13 is detachably connected to the support plate 10, and the wiper rubber strip 13 can be removed from the support plate 10 to facilitate the replacement of the wiper rubber strip 13.
[0032] The driving device includes a push block 14, a sliding guide rail 3, a slider 4 and an electrically controlled telescopic member. The push block 14 is arranged in the middle of the support plate 10 on the side facing the mounting seat 1 and has a first beveled surface. The thickness of the push block Ⅰ is not less than 4 mm. The sliding guide rail 3 is fixedly mounted on the bottom surface of the mounting seat 1, and its length direction is arranged parallel to the mounting seat 1. The slider 4 is slidably mounted on the sliding guide rail 3, and is provided with a push block 2 15 for driving the push block 14 to move relative to the mounting seat 1. The push block 2 15 has a second beveled surface, and the first beveled surface matches the second beveled surface. The electrically controlled telescopic member is fixedly mounted on the mounting seat 1 and connected to the slider 4. The telescopic direction of the electrically controlled telescopic member is parallel to the sliding direction of the slider 4. Among them, the electrically controlled telescopic member is an electromagnetic push-pull switch 5.
[0033] The working principle of the driving device is as follows: in the non-defog state, the electromagnetic push-pull switch 5 is powered off, and the slider 4 is in the initial position. At this time, the chamfered surfaces of the push block 14 and the push block 2 15 are in contact or opposite to each other, and the two form a rectangular parallelepiped, and the distance between the wiper strip 2 and the front side window glass is 3mm. When defog is required, the electromagnetic push-pull switch 5 is powered on, and the slider 4 is pulled, so that the push block 2 15 pushes the push block 1 14, so that the wiper strip 2 moves 4mm toward the front side window glass, close to the front side window glass, and the wiper rubber strip 13 is compressed, resulting in a 1mm deformation. At the same time, the return springs 7 at both ends are compressed. After the defog state is released, the electromagnetic push-pull switch 5 is powered off, and the return spring of the electromagnetic push-pull switch 5 works to push the slider 4 back to its original position, so that the push block 2 15 is separated from the push block 1 14. At the same time, the wiper strip 2 is separated from the glass and returns to its original position under the action of the return spring 7. The electromagnetic push-pull switch 5 should have the following properties: the electromagnetic force when powered on can overcome the force of the return spring to move the slider 4 a set distance, and the elastic force of the return spring can slide the slider 4 to the initial position after power is off.
[0034] The control system is located on the inner side of the door of the car and is electrically connected to the driving devices of the two wiper devices. The control system drives the wiper strip 2 to be close to or away from the glass of the front side window by controlling the driving device to perform a telescopic action. Among them, the control system includes a defogger button and a timing switch. The defogger button is electrically connected to the timing switch, and the timing switch is electrically connected to the driving devices of the two wiper devices. Specifically, the timing switch is electrically connected to the electromagnetic push-pull switch 5 of the two wiper devices, thereby controlling the electromagnetic push-pull switch 5 to be powered on or off, and has a timing function. The control system also includes a window glass lift controller arranged in the front door of the car. The defogger button is electrically connected to the window glass lift controller, and the window glass lift controller is electrically connected to the two front window glass lifts.
[0035] The control system of the utility model combines the wiper device drive control and the front window lifting control to realize a one-button operation function, optimize the defog operation process, and help improve the user experience. When defog is required, the driver presses the defog button, triggering the timing switch and the window glass lifting controller at the same time. The timing switch controls the wiper device to enter the wiping position and maintain it for a period of time. During this period of time, the window glass lifting controller controls the front window glass lifting machine to complete a descending-ascending action, thereby completing the wiping and defog work. Then the timing switch stops working, and the wiper device returns to the non-wiping state under the action of its own return spring 7.
[0036] The utility model can effectively solve the problem that the driver's observation of the exterior rearview mirror is affected by fogging and water on the outer side of the front side window glass, thereby improving driving safety, not affecting the appearance of the car, not increasing the wind resistance of the car, and not increasing the working resistance of the front window glass lifter during defogger, thereby ensuring the service life of the front window glass lifter. Installing the wiper device in the car door can avoid the influence of rain and sunlight, thereby extending the service life and replacement cycle of the wiper rubber strip 13.
[0037] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
