Technical Field
[0001] This utility model relates to the field of automotive cleaning tools, specifically to a car de-icing scraper for removing ice and snow from car windows or car body surfaces in winter. Background Technology
[0002] In winter, car windows and car body surfaces often develop frost, ice, or snow. To ensure driving safety, car owners or drivers usually use ice scrapers to clear these deposits.
[0003] Most existing ice scrapers feature a double-bladed design with a row of ice-breaking teeth on the back. These scrapers are typically made of high-quality ABS material, making them less likely to scratch car paint. However, most existing scrapers have a plate-like structure, resulting in lower overall strength and a tendency to deform during use, thus affecting their ice-removing effectiveness. Utility Model Content
[0004] To address the aforementioned shortcomings, the technical problem to be solved by this utility model is to provide a vehicle de-icing scraper that solves the problems of low strength, easy deformation, and poor de-icing effect of existing scraper blades.
[0005] Therefore, this utility model provides a vehicle de-icing scraper, including a scraper head and a scraper blade disposed at the front end of the scraper head. The back of the scraper blade is provided with a row of ice-breaking teeth. The scraper head includes a scraper head body, and a scraper head connecting part is provided at its front end. The thickness of the scraper head connecting part is greater than the thickness of the scraper head body. A slot is provided on its front end face, and at least two scraper blade locking holes are provided on its upper surface. The scraper blade includes a scraper blade body, and a scraper blade connecting part is provided at its rear end. An insert plate that is adapted to the slot is provided on the rear end face of the scraper blade connecting part. A locking pin that matches the scraper blade locking holes is provided on the upper surface of the insert plate. The thickness of the scraper blade connecting part is greater than the thickness of the insert plate. The insert plate is inserted into the slot, and the locking pin is engaged with the scraper blade locking holes.
[0006] Based on the above technical solutions, by setting a thickened structure at the connection between the shovel head and the blade, the overall strength is improved, the resistance to deformation is enhanced, and the de-icing efficiency and service life are increased.
[0007] In the above technical solution, preferably, the locking pin is provided with a slope with its root inclined towards the inside of the slot, which facilitates insertion and improves assembly efficiency.
[0008] In the above technical solution, preferably, the axis of the shovel hole is inclined relative to the upper surface of the shovel head connection, and the inclination direction is from bottom to top toward the front end of the shovel, so that the force is more reasonable and the connection stability is improved.
[0009] In the above technical solution, preferably, the row of ice-breaking teeth is evenly arranged along the width direction of the shovel body to improve the ice-breaking effect.
[0010] In the above technical solution, preferably, the front end of the inner wall of the slot is provided with a groove, and the rear wall of the groove is sloped, which is consistent with the slope direction of the locking pin, which helps the insertion positioning and smoothness.
[0011] In the above technical solution, preferably, the two sides of the shovel body are bent upward to form flanges, which enhances the structural strength and prevents deformation.
[0012] In the above technical solution, preferably, the back of the shovel head body is provided with honeycomb grooves, so that the force is more even when shoveling ice, and at the same time, some grooves are connected to form through holes, which facilitates storage.
[0013] In the above technical solution, preferably, the rear end of the shovel head is provided with a connecting sleeve, and the end of the connecting sleeve is provided with a shovel rod locking hole or a connecting thread for connecting with the shovel rod.
[0014] In the above technical solution, preferably, the angle between the back side of the blade and the end face is 45 degrees, and the angle between the front side of the blade and the end face is 90 degrees.
[0015] As can be seen from the above technical solution, the front end of the shovel head and the rear end of the shovel blade of this utility model are respectively provided with a thickened shovel head connecting part and a shovel blade connecting part. By optimizing the connection structure between the shovel head and the shovel blade, the overall structural strength of the de-icing shovel is significantly enhanced after assembly.

[0027] Existing ice scrapers mostly have plate-shaped blades, which have low strength and are prone to deformation during use. To address this, this invention improves overall strength, enhances impact resistance, and increases de-icing efficiency by incorporating a thickened structure at the connection between the scraper head and the blade, and employing a detachable connection method using a plate and slot.
[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. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0029] To provide a clearer explanation and description of the technical solution and implementation method of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are introduced below.
[0030] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.
[0031] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a vehicle de-icing scraper, including a scraper head 10 and a scraper blade 20 disposed at the front end of the scraper head 10. The scraper blade 20 and the scraper head 10 adopt a detachable connection structure, which facilitates the replacement of the scraper blade after wear and reduces the cost of use.
[0032] The shovel head 10 includes a shovel head body 11, with a shovel head connecting part 12 at its front end. The thickness of the shovel head connecting part 12 is greater than the thickness of the shovel head body 11. The front end of the shovel head connecting part 12 is provided with a slot 13, and the upper surface is provided with two shovel blade locking holes 14.
[0033] The scraper 20 includes a scraper body 21, with a scraper connecting part 22 at its rear end. An insert plate 23 is provided on the rear end face of the scraper connecting part 22, and a locking pin 24 is provided on the upper surface of the insert plate 23. After the insert plate 23 is inserted into the slot 13, the locking pin 24 engages with the scraper locking hole 14, achieving connection. The upper and lower surfaces of the insert plate 23 have chamfered structures to facilitate smooth insertion and assembly.
[0034] Through the above structural design, the front end of the shovel head 10 and the rear end of the shovel blade 20 are respectively provided with thickened shovel head connecting parts and shovel blade connecting parts. After assembly, the overall structural strength of the de-icing shovel can be significantly enhanced, making it more resistant to external forces during use, less prone to deformation or breakage, and able to maintain a good working condition for a longer period of time, thus completing the de-icing task more efficiently.
[0035] The inner wall of slot 13 has a groove 15 at the front end corresponding to the spatula hole 14. When assembling the spatula 20, the locking pin 24 is aligned with the groove 15 and inserted into slot 13. The rear end face of slot 13 is sloped, with the lower end inclined towards the inside of slot 13. This design provides a clear alignment position for locking pin 24 with the groove 15, making the insertion plate 23 more precise when inserted into slot 13. The sloped rear end face of slot 13 guides locking pin 24 smoothly across the groove 15 into spatula hole 14, improving the smoothness of assembly.
[0036] The back of the shovel head body 11 is provided with honeycomb grooves 16. The honeycomb groove structure distributes the force more evenly when shoveling and removing ice. Several units in the honeycomb grooves 16 penetrate the shovel head body 11 to form through holes 17. The through holes 17 can be used as hanging holes to hang the ice removal shovel on the wall for storage.
[0037] In this embodiment, the through holes 17 are designed in two rows, two in the upper row and three in the lower row, utilizing the principle of wind mechanics to form a pressure plate effect. Specifically, during the ice removal process, when wind blows into the through holes 17, the wind speed increases, resulting in a decrease in the air pressure inside the through holes. According to Bernoulli's principle, when the fluid (wind) velocity increases, its static pressure decreases. At this time, the air pressure outside the scraper head is relatively high, thus generating a downward pressure on the scraper head, thereby acting as a "pressure plate" to make the scraper more stably adhere to the car window or car body surface. In addition, when the wind passes through the through holes, it may also produce an effect similar to "airflow adsorption," further enhancing the stability of the scraper head during the ice removal process. This design not only optimizes the ice removal effect but also improves operability and practicality.
[0038] The rear end of the shovel head 10 is provided with a connecting sleeve 18, and the outer end of the connecting sleeve 18 is provided with a shovel rod locking hole 19 for assembly and connection with the elastic buckle on the shovel rod. Alternatively, the end of the connecting sleeve 18 is provided with a connecting thread for threaded connection with the shovel rod.
[0039] like Figure 4 As shown, in one embodiment, the root of the locking pin 24 is provided with a ramp 25 that slopes towards the inside of the slot 13, which facilitates the smooth entry of the locking pin 24 into the shovel hole 14.
[0040] The two sides of the blade body 21 are bent upward to form flanges 27, which enhances the overall strength of the blade body 21 and makes it less prone to deformation during use.
[0041] The back of the blade body 21 is provided with a row of ice-breaking teeth 26, which are evenly arranged along the width of the blade body 21. When encountering hard ice and snow that is difficult to clear, the ice-removing blade can be flipped over, the ice-breaking teeth 26 can be used to break the ice, and then the blade can be flipped back to remove the ice, thereby improving the ice removal efficiency.
[0042] The base of the insert plate 23 is provided with multiple protruding ribs 28, which extend along the length of the insert plate 23. The protruding ribs 28 can make the insert plate 23 fit more tightly with the slot 13 after assembly, so that it will not shake during use and the operation is more stable.
[0043] like Figure 5 , Figure 6 As shown, the axis of the shovel retaining hole 14 is inclined relative to the upper surface of the shovel head connecting part 12, with the inclination direction from bottom to top towards the front end of the shovel. This design makes the force direction more reasonable after the retaining pin 24 is inserted, which can better withstand the impact force on the shovel 20 during use and improve the stability of the overall structure.
[0044] This invention features an ice-shoveling function when used from the front, and an ice-breaking function when flipped over using ice-breaking teeth. The blade 20 has a continuous three-line shape at its end, with the angle B between the back of the blade and the end face designed to be 45 degrees for higher efficiency during ice-breaking. The angle C between the front of the blade and the end face is designed to be 90 degrees, which is more suitable for ice-shoveling. By designing different angles, this invention provides good operability for both ice-shoveling and ice-breaking.
[0045] Based on the above description of specific embodiments, the vehicle de-icing scraper provided by this utility model has the following advantages compared with the prior art:
[0046] First, the front end of the shovel head and the rear end of the blade are respectively equipped with thickened shovel head connecting parts and blade connecting parts. After assembly, the overall structural strength of the ice removal shovel can be significantly enhanced, making it more resistant to external forces during use, less prone to deformation or breakage, and more efficient in completing the ice removal task.
[0047] Secondly, the axis of the locking hole is inclined relative to the upper surface of the shovel head connection, with the inclination direction from bottom to top towards the front end of the shovel. This design results in a more reasonable force direction after the locking pin is inserted, which can better withstand the impact force on the shovel during use and improve the stability of the overall structure.
[0048] Third, the back of the shovel head has honeycomb grooves, which distribute the force more evenly when shoveling ice. Several units in the honeycomb grooves penetrate the shovel head to form a through hole, which can be used to hang it on the wall for easy storage.
[0049] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0050] This utility model is not limited to the above-described preferred embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
