Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, specifically a cleaning device for automotive headlight covers. Background Technology

[0002] With the rapid development of the automotive industry, automotive lamp covers, as an important component of the vehicle lighting system, not only undertake the basic functions of protecting the internal light source and reflecting and transmitting light, but also have a key impact on the appearance and driving safety of the vehicle. Traditional automotive lamp covers are mostly made of materials such as polycarbonate (PC), which have a certain degree of light transmittance and impact resistance. However, they are easily corroded by ultraviolet rays, high and low temperature environments and chemical substances during long-term use, resulting in yellowing, cracking and other phenomena, which leads to a decrease in light transmittance and affects the lighting effect.

[0003] An existing cleaning device for car headlight covers typically includes a set of handles, one end of which is equipped with a motor, and the other end of which is equipped with a rotating base. A polishing pad is mounted on one side of the rotating base. When the surface of the car headlight cover becomes yellowed or oxidized, pressing the rotating polishing pad can effectively clean the surface of the headlight cover.

[0004] However, for an existing cleaning device for car headlight covers, since the surface of car headlight covers is usually designed as a curved surface, when the polishing pad is pressed against the headlight cover, the polishing efficiency of the middle part of the polishing pad is higher than that of the edge part, which will make the thickness of the headlight cover thinner and affect the normal use of the headlight cover. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a cleaning device for automotive lamp covers, so as to solve the technical problem mentioned in the background art that the existing cleaning device for automotive lamp covers has poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for automotive headlight covers, comprising a handle, a grinding motor fixedly mounted at one end of the handle, a turntable fixedly mounted at the output end of the grinding motor, a first inner cavity on one side of the turntable, a second inner cavity and a third inner cavity inside the turntable, a rotating block sleeved in the third inner cavity, a rotating rod sleeved in the rotating block, a limiting plate sleeved on the outer wall of the rotating rod, and multiple sets of first springs and second springs fixedly mounted on one side of the limiting plate, a first slider connected to one end of the first spring, a first support rod fixedly mounted on one side of the first slider, a second grinding pad fixedly mounted on one end of the first support rod, a second slider connected to one end of the second spring, a second support rod fixedly mounted on one side of the second slider, and a third grinding pad fixedly mounted on one end of the second support rod.

[0007] By adopting the above technical solution, the problem of poor performance of an existing cleaning device for automotive lamp covers mentioned in the background art is solved. This is achieved by incorporating a second and a third polishing pad, which are fixedly installed at the ends of a first support rod and a second strut. The first and second support rods are fixedly installed on one side of a first and a second slider. A first and a second spring are connected to one side of the first and second sliders and are fixedly installed on one side of a limiting plate. When the turntable moves to the curved surface of the automotive lamp cover, the compressed second and third polishing pads can press down on the first and second springs, causing the first and second sliders to slide to one side. This allows the second and third polishing pads to contract to one side, preventing excessive polishing when in contact with the curved surface of the automotive lamp cover, which would otherwise affect its normal use.

[0008] The present invention is further configured such that a first polishing pad is fixedly installed at the bottom of the turntable, and the height of the first polishing pad is the same as the height of the second polishing pad and the third polishing pad.

[0009] Preferably, a first polishing pad is fixedly installed at the bottom of the turntable, and the height of the first polishing pad is the same as the height of the second and third polishing pads, so that the turntable has the function of polishing and cleaning when it is working.

[0010] The present invention is further configured such that an annular protrusion is fixedly installed on the inner wall of the first inner cavity, and the annular protrusion is sleeved inside the rotating block.

[0011] Preferably, an annular protrusion is fixedly installed on the inner wall of the first inner cavity, and the annular protrusion is sleeved inside the rotating block, so that the rotating block can be slidably installed in the first inner cavity.

[0012] The present invention is further configured such that the rotating block is provided with an internal thread, the outer wall of the rotating rod is provided with an external thread, and the rotating block and the rotating rod are movably connected by the thread.

[0013] Preferably, the rotating block has an internal thread and the outer wall of the rotating rod has an external thread. The rotating block and the rotating rod are connected by the thread, so that the rotating block can slide and adjust the rotating rod when it rotates.

[0014] The present invention is further configured such that the first support rod and the second strut are both polygonal, and the first slider, the second slider, the second inner cavity, and the third inner cavity are in close contact with each other.

[0015] Preferably, by setting both the first support rod and the second strut as polygonal shapes, the first slider and the second slider are prevented from rotating during operation, thereby affecting the normal use of the device. The first slider and the second slider, as well as the walls of the second inner cavity and the third inner cavity, are tightly fitted, so that the first slider and the second slider can be stably installed in the second inner cavity and the third inner cavity.

[0016] The present invention is further configured such that one end of both the second and third polishing pads is provided with an arc-shaped surface, and the second and third polishing pads do not contact each other.

[0017] Preferably, by providing an arc-shaped surface at one end of both the second and third polishing pads, the second and third polishing pads do not contact each other, which facilitates the second and third polishing pads to fit into the arc-shaped surface of the car headlight cover.

[0018] The present invention is further configured such that a circular groove is formed inside the rotating rod, and the limiting plate is sleeved inside the circular groove.

[0019] Preferably, a circular groove is provided inside the rotating rod, and a limiting plate is sleeved inside the circular groove, so that the limiting plate can be locked on the rotating rod and can be slidably set.

[0020] The present invention is further configured such that the height of the first spring is less than the height of the second inner cavity, and the height of the second spring is less than the height of the third inner cavity.

[0021] Preferably, by setting the height of the first spring to be less than the height of the second inner cavity, and the height of the second spring to be less than the height of the third inner cavity, the strength of the first spring and the second spring is avoided from being too great, which would affect the normal use of the device.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by providing a handle, a grinding motor, a turntable, a first inner cavity, a second inner cavity, a third inner cavity, a first grinding pad, a rotating block, a rotating rod, a limiting plate, a first spring, a second spring, a first slider, a first support rod, a second grinding pad, a second slider, a second support rod, and a third grinding pad, solves the problem of poor performance of an existing cleaning device for automotive lamp covers mentioned in the background art. By providing a second grinding pad and a third grinding pad, when the turntable moves to the curved surface of the automotive lamp cover, the second and third grinding pads, under pressure, can slide the first and second sliders to one side by pressing the first and second springs, allowing the second and third grinding pads to contract to one side. This prevents the second and third grinding pads from excessively grinding when in contact with the curved surface of the automotive lamp cover, thus affecting the normal use of the automotive lamp cover.

[0024] 2. This utility model utilizes a rotating block. When the device is polishing and cleaning the surface of car headlight covers with different curvatures, rotating the rotating block allows the rotating rod fitted inside the rotating block to slide to one side, thereby moving the limiting plate to one side. This allows adjustment of the installation position of the limiting plate. The limiting plate, which moves to one side, can pull the first and second sliders into the second and third inner cavities through the fixedly installed first and second springs. This causes the second and third polishing pads to retract inward, allowing the first, second, and third polishing pads to be arranged in a gradient, which can better fit the car headlight cover and improve the practicality of the device.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Please see Figures 1-5The device includes a handle 1 for easy use. A grinding motor 2 is fixedly mounted on one end of the handle 1, and a turntable 3 is fixedly mounted on the output end of the grinding motor 2. A first inner cavity 31 is formed on one side of the turntable 3, and a second inner cavity 32 and a third inner cavity 33 are formed inside the turntable 3. A rotating block 4 is fitted inside the third inner cavity 33, and a rotating rod 5 is fitted inside the rotating block 4. A limiting plate 6 is fitted on the outer wall of the rotating rod 5. Multiple sets of first springs 7 and second springs 71 are fixedly mounted on one side of the limiting plate 6. The limiting plate 6 can control the first springs 71. The position of the second spring 71 serves an adjustment function. One end of the first spring 7 is connected to the first slider 8. A first support rod 81 is fixedly installed on one side of the first slider 8. A second polishing pad 82 is fixedly installed on one end of the first support rod 81. One end of the second spring 71 is connected to the second slider 9. A second support rod 91 is fixedly installed on one side of the second slider 9. A third polishing pad 92 is fixedly installed on one end of the second support rod 91. Through the setting of the second polishing pad 82 and the third polishing pad 92, the device can play a cleaning role when it is working.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A first polishing pad 34 is fixedly installed at the bottom of the turntable 3. The height of the first polishing pad 34 is the same as the height of the second polishing pad 82 and the third polishing pad 92. By fixing the first polishing pad 34 at the bottom of the turntable 3, the turntable 3 has the function of polishing and cleaning when it is working.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 4 An annular protrusion is fixedly installed on the inner wall of the first inner cavity 31. The annular protrusion is sleeved inside the rotating block 4. By fixing the annular protrusion on the inner wall of the first inner cavity 31 and sleeved inside the rotating block 4, the rotating block 4 can be slidably installed in the first inner cavity 31.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The rotating block 4 has an internal thread, and the outer wall of the rotating rod 5 has an external thread. The rotating block 4 and the rotating rod 5 are connected by a thread. By having an internal thread in the rotating block 4 and an external thread on the outer wall of the rotating rod 5, the rotating block 4 and the rotating rod 5 are connected by a thread. When the rotating block 4 rotates, it can play a sliding adjustment role for the rotating rod 5.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 5Both the first support rod 81 and the second support rod 91 are polygonal. The first slider 8, the second slider 9, the second inner cavity 32, and the third inner cavity 33 are tightly fitted together. By making both the first support rod 81 and the second support rod 91 polygonal, the first slider 8 and the second slider 9 are prevented from rotating during operation, thus affecting the normal use of the device. The tight fit between the first slider 8, the second slider 9, the second inner cavity 32, and the third inner cavity 33 allows the first slider 8 and the second slider 9 to be stably installed in the second inner cavity 32 and the third inner cavity 33.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 4 Both the second polishing pad 82 and the third polishing pad 92 have an arc-shaped surface at one end, and the second polishing pad 82 and the third polishing pad 92 do not contact each other. By having an arc-shaped surface at one end of both the second polishing pad 82 and the third polishing pad 92, and by not contacting each other, it is easy for the second polishing pad 82 and the third polishing pad 92 to fit into the arc-shaped surface of the car headlight cover.

[0040] For details regarding the above embodiments, please refer to [link / reference].

By having an annular groove in the rotating rod 5 and the limiting plate 6 fitted inside the annular groove, the limiting plate 6 can be locked onto the rotating rod 5, and the limiting plate 6 can be slidably set.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The height of the first spring 7 is less than the height of the second inner cavity 32, and the height of the second spring 71 is less than the height of the third inner cavity 33. By setting the height of the first spring 7 to be less than the height of the second inner cavity 32 and the height of the second spring 71 to be less than the height of the third inner cavity 33, the strength of the first spring 7 and the second spring 71 is avoided from being too great, which would affect the normal use of the device.

[0042] In practical operation, this invention works as follows: The rotating block 4 rotates according to the curvature of the car headlight cover surface. The installation position of the limiting plate 6 is adjusted via the rotating rod 5, allowing the second polishing pad 82 and the third polishing pad 92 to slide inwards to a certain extent by compressing the first spring 7 and the second spring 71. This allows the device to better fit the curved surface of the car headlight cover during use, resulting in a better polishing and cleaning effect. When in use, the operator holds the handle 1, allowing the first polishing pad 34, the second polishing pad 82, and the third polishing pad 92 to contact the car headlight cover surface and applying a certain amount of pressure to them. The first polishing pad 34, the second polishing pad 82, and the third polishing pad 92 can clean and polish the surface of the car headlight cover, preventing yellowing and affecting its normal use. When the handle 1 is held to clean and polish the curved surface of the car headlight cover, the operator squeezes the second polishing pad 82 and the third polishing pad 92, causing them to press inward against the first spring 7 and the second spring 71. This allows the second polishing pad 82 and the third polishing pad 92 to retract inward, preventing them from over-polishing the curved surface of the car headlight cover when they come into contact with it, thus affecting the performance of the headlight cover.
