Description

Technical Field

[0001] This utility model relates to the field of automotive cleaning equipment technology, and in particular to a fully automatic automotive sunroof cleaning device. Background Technology

[0002] Sunroofs are becoming increasingly popular as a feature that enhances the driving experience. However, sunroof glass is easily exposed to the elements for extended periods, accumulating dust, rain stains, bird droppings, and other dirt, which not only affects the vehicle's appearance but also reduces the amount of light entering the cabin. Traditional manual cleaning methods are time-consuming and laborious, and ordinary car owners often cannot reach the central area of ​​the sunroof, resulting in incomplete cleaning. Therefore, automated or semi-automated cleaning devices for car sunroofs have emerged on the market.

[0003] Existing car cleaning systems typically consist of a fixed frame and a cleaning head that reciprocates across it. However, different car brands and models have varying sunroof sizes and designs, ranging from standard-sized sunroofs to larger panoramic sunroofs. This results in poor versatility for fixed-size cleaning systems, making them difficult to install and secure effectively on diverse vehicle models, causing significant inconvenience for users.

[0004] More importantly, to meet the requirements of aerodynamic design and structural strength, the glass surface of a car sunroof is not perfectly flat, but generally has a certain curvature. Most existing cleaning devices use rigid or semi-rigid cleaning heads. When these cleaning heads are used to clean the curved surface of a sunroof, the brush strip at the bottom cannot fully conform to the curvature of the glass, resulting in uneven pressure distribution on the glass surface. This easily creates cleaning blind spots in the center or edge areas of the sunroof, seriously affecting the final cleaning quality and effect.

[0005] Therefore, this utility model proposes a fully automatic car sunroof cleaning device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing fully automatic car sunroof cleaning devices with fixed dimensions, which make it difficult to adapt to sunroofs of different sizes and curvatures, resulting in inconvenient installation and poor cleaning effect, this utility model aims to provide a fully automatic car sunroof cleaning device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a fully automatic car sunroof cleaning device, including an arc-shaped bracket, an arc-shaped extension block, a support plate, a cylinder, a cleaning structure, a suction cup; as well as a cylindrical sleeve, a locking post, a connecting plate, a pushing block, a brush strip, a limiting post, a spring one, a spring two, and a spring three.

[0008] Among them, a unique combination method enables the adjustment of the length of the body frame and the curvature adaptive cleaning system.

[0009] Specifically, the arc-shaped extension block and the arc-shaped bracket are combined via a sliding fit. A cylindrical sleeve is mounted on the arc-shaped extension block, and a locking pin can extend and retract through the cylindrical sleeve and selectively insert into multiple circular holes on the arc-shaped bracket. By inserting and removing the locking pin, the position of the arc-shaped extension block relative to the arc-shaped bracket is locked and unlocked, allowing for convenient adjustment of the overall length of the device. Simultaneously, the connecting plate inside the cleaning structure is connected to the limiting post with the brush strip installed via elastically configured springs one, two, and three. When the connecting plate reciprocates along the support plate driven by the cylinder and the push block, the elastic connection structure allows the brush strip to float freely relative to the connecting plate, thus closely conforming to the surface curvature of the sunroof.

[0010] Preferably, in order to ensure the high stability and anti-deflection capability of the cleaning structure during reciprocating motion, U-shaped support bars are fixedly connected to both sides of the support plate, and T-shaped slide bars are fixedly connected to both sides of the connecting plate. The T-shaped slide bars slide within the U-shaped support bars, forming a stable and reliable sliding guide mechanism.

[0011] Preferably, to further improve the guiding accuracy of the adjustment process, the side of the arc-shaped bracket is provided with an arc-shaped groove, and the top of the bracket is provided with an elongated groove. A limit block is correspondingly provided on the arc-shaped extension block, so that the cylindrical sleeve slides in the arc-shaped groove and the limit block slides in the elongated groove, providing double guiding and limiting.

[0012] Preferably, in order to achieve automation and convenience of locking the locking pin, the inside of the cylindrical sleeve is filled with inert gas, and a retaining ring is provided on the locking pin. When the locking pin is pulled, the inert gas is compressed, and the elastic force generated after releasing the hand can push the locking pin to automatically spring back and lock.

[0013] Preferably, in order to easily fix the device to the vehicle body, the bottom of the arc-shaped extension block is provided with a threaded hole and a threaded post. One end of the threaded post is rotatably connected to the suction cup, and the other end is threaded into the threaded hole. The adsorption force can be adjusted by rotating the suction cup.

[0014] Preferably, in order to better adapt to the complex curvature of the car window, the second spring is composed of three independent spring structures. This multi-point independent support method can achieve more precise local adaptive adjustment and ensure that the brush strip fits tightly with the curved surface.

[0015] Preferably, the fully automatic car sunroof cleaning device also includes a support rod, which is mounted on a support plate to enhance the overall structural strength of the support plate.

[0016] Preferably, a guide groove is provided in the middle of the support plate, and the bottom of the connecting plate slides into it, serving as one of the main sliding tracks, which further improves the stability of the movement.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problem of existing cleaning devices having fixed dimensions and being difficult to adapt to sunroofs of different sizes by setting up relatively sliding arc-shaped brackets and arc-shaped extension blocks, and cooperating with the locking post and cylindrical sleeve for length locking. It achieves the technical effect of being able to freely adjust the length of the device, making it convenient to fix and clean on different vehicle models.

[0019] 2. This utility model solves the problem that the brush strip of the existing cleaning device cannot closely fit the curvature of the sunroof and easily creates cleaning dead corners by elastically setting spring 1, spring 2 and spring 3 between the connecting plate and the limiting post on which the brush strip is installed. It achieves the technical effect of making the brush strip always fit the sunroof surface and self-adjusting, thereby making the cleaning effect better.

[0020] 3. This utility model solves the problem of shaking or deflection of the cleaning structure during reciprocating motion by sliding the T-shaped sliding rods set on both sides of the connecting plate with the U-shaped support strips fixed on both sides of the support plate, thus achieving the technical effect of ensuring a stable cleaning process and precise guidance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please refer to Figures 1 to 5 This utility model embodiment provides a fully automatic car sunroof cleaning device, including an arc-shaped bracket 3 with multiple circular holes 4, an arc-shaped extension block 8 slidably fitted to the arc-shaped bracket 3, a support plate 1 fixedly connected to the arc-shaped extension block 8, the support plate 1 serving as the mounting base for the cleaning system, a cylinder 12 mounted on the support plate 1, a cleaning structure 2 slidably mounted on the support plate 1 and connected to the cylinder 12 for transmission, the cleaning structure 2 performing sunroof cleaning action, and a suction cup 10 mounted on the bottom of the arc-shaped extension block 8.

[0031] The fully automatic car sunroof cleaning device also includes a cylindrical sleeve 6 and a locking post 5. The cylindrical sleeve 6 is set on the arc-shaped extension block 8. The locking post 5 can extend and retract through the cylindrical sleeve 6 and can be selectively inserted into the circular hole 4, thereby locking the arc-shaped extension block 8 relative to the arc-shaped bracket 3, realizing the adjustable length function of the device.

[0032] like Figure 2 and Figure 3As shown, the cleaning structure 2 includes a connecting plate 201, which is slidably connected to the support plate 1. A pushing block 205 is fixedly connected to the connecting plate 201 and connected to the piston rod of the cylinder 12. The cylinder 12 drives the pushing block 205, thereby driving the connecting plate 201 to reciprocate. The cleaning structure 2 also includes a brush strip 208 and a limiting post 206. The brush strip 208 is installed on the limiting post 206. In order to achieve arc-adaptive cleaning, the cleaning structure 2 is also equipped with spring 1 202, spring 203 and spring 3 207. Spring 1 202, spring 203 and spring 3 207 are all elastically set between the connecting plate 201 and the limiting post 206. Through the elastic support of these three sets of springs, the brush strip 208 can always conform to the arc of the sunroof surface during the cleaning process, realizing adaptive floating cleaning.

[0033] Please refer to Figure 2 and Figure 3 The support plate 1 has U-shaped support bars 209 fixedly connected to both sides. Each U-shaped support bar 209 has a U-shaped guide groove extending along its length, which guides and limits the sliding of the cleaning structure 2. Simultaneously, the connecting plate 201 has T-shaped slide bars 204 fixedly connected to both sides. Each T-shaped slide bar 204 has a T-shaped profile that matches the shape and size of the U-shaped support bars 209. In the assembled state, the T-shaped slide bars 204 slide within the U-shaped support bars 209, ensuring high stability and anti-deflection capability when the connecting plate 201 reciprocates along the length of the support plate 1 under the push of the cylinder 12.

[0034] A guide groove is provided in the middle of the support plate 1, and the bottom of the connecting plate 201 is slidably fitted in the guide groove. The guide groove, together with the U-shaped support bar 209 and the T-shaped slide bar 204, constitutes the complete sliding guide system of the cleaning structure 2.

[0035] In this embodiment, a cylinder 12 is used as the power source to drive the connecting plate 201 to move. The cylinder 12 is fixedly installed on the support plate 1, and its piston rod is fixedly connected to the push block 205. The push block 205 is fixedly connected to the connecting plate 201. The cylinder 12 drives the connecting plate 201 to reciprocate by pushing and pulling the piston rod, thereby realizing the automated scraping of the cleaning structure 2. Its specific internal structure is a well-known technology in the field and will not be described in detail here.

[0036] In addition, the fully automatic car sunroof cleaning device also includes a support rod 11, which is mounted on the support plate 1 to enhance the overall structural strength of the support plate 1.

[0037] As a preferred embodiment, please refer to Figure 4To ensure that the arc-shaped extension block 8 has a precise and stable trajectory when sliding along the arc-shaped bracket 3, the side of the arc-shaped bracket 3 is provided with an arc-shaped groove, and the top of the arc-shaped bracket 3 is provided with a long groove. The arc-shaped extension block 8 is provided with a limiting block 7, the cylindrical sleeve 6 is slidably fitted in the arc-shaped groove, and the limiting block 7 is slidably fitted in the long groove.

[0038] As another preferred embodiment, please refer to Figure 5 In order to achieve automatic reset and locking of the locking post 5, the inside of the cylindrical sleeve 6 is filled with inert gas, and a retaining ring is provided on the locking post 5. When the locking post 5 is pulled, the retaining ring will compress the inert gas. After the locking post 5 is released, the inert gas expands and pushes the retaining ring, causing the locking post 5 to spring back and insert into the circular hole 4.

[0039] As another preferred embodiment, please refer to Figure 1 In order to adjust the height of the suction cup 10 and provide a firm adsorption force, the bottom of the arc-shaped extension block 8 is provided with a threaded hole and a threaded post 9. One end of the threaded post 9 is rotatably connected to the suction cup 10, and the other end of the threaded post 9 is threaded into the threaded hole. By rotating the suction cup 10, the threaded post 9 is rotated, thereby changing the height of the suction cup 10 relative to the arc-shaped extension block 8.

[0040] As another preferred embodiment, please refer to Figure 2 In order to enable the brush strip 208 to better adapt to the different curvatures of the sunroof surface, the spring 203 is composed of three independent spring structures. This multi-point independent support method allows different areas of the brush strip 208 to rise and fall independently according to local curvature changes, ensuring a tighter fit.

[0041] Working principle: During installation and adjustment, first pull the locking post 5. Under the pulling force, the locking post 5 will retract and disengage from the circular hole 4 opened on the arc bracket 3. At this time, the arc extension block 8 can slide on the arc bracket 3. The limiting block 7 on the arc extension block 8 will slide along the long groove on the top of the arc bracket 3. At the same time, the cylindrical sleeve 6 will slide along the arc groove on the side of the arc bracket 3, thus ensuring the stability and accuracy of the sliding of the arc extension block 8. After adjusting to the length suitable for the sunroof, release the locking post 5. The locking post 5 will automatically reset under the elastic force of the inert gas inside the cylindrical sleeve 6 and lock into the new circular hole 4 to complete the length locking. Then, rotate the suction cup 10 located at the bottom of the arc extension block 8. The suction cup 10 will drive the threaded post 9 to rotate in the threaded hole at the bottom of the arc extension block 8, changing the height of the suction cup 10 to generate suction force, and firmly fix the entire device next to the sunroof.

[0042] During cleaning, cylinder 12 is activated. The piston rod of cylinder 12 drives the push block 205, which in turn drives the fixedly connected connecting plate 201 to begin reciprocating motion. The T-shaped slide bar 204 on the connecting plate 201 slides within the U-shaped support bars 209 on both sides of the support plate 1. At the same time, the bottom of the connecting plate 201 slides within the guide groove in the middle of the support plate 1. This coordinated structure provides precise guidance for the reciprocating motion of the cleaning structure 2, ensuring the smoothness and linearity of the scraping action. During the process of the connecting plate 201 driving the brush bar 208 to scrape the sunroof, due to the spring... Spring 1 202, Spring 2 203 and Spring 3 207 are elastically disposed between the connecting plate 201 and the limiting post 206 that carries the brush strip 208. When the brush strip 208 encounters the curved surface of the sunroof, these springs will provide adaptive elastic force, so that the limiting post 206 can drive the brush strip 208 to float and rise relative to the connecting plate 201, always closely adhering to the surface of the sunroof. In particular, the three independent spring structures adopted by Spring 2 203 can more precisely adapt to different curvature changes, thereby solving the problem of incomplete cleaning caused by the inability to adhere to the curved surface in the prior art.
