Description

Technical Field

[0001] This utility model relates to the field of windshield wiper technology, and in particular to a windshield wiper structure for a tricycle. Background Technology

[0002] Three-wheeled vehicle windshield wipers are safety auxiliary devices used to remove rainwater, fog, dust, and other debris from the windshield of three-wheeled vehicles, ensuring clear visibility for drivers in rainy or inclement weather. They are primarily used in freight, passenger, and agricultural three-wheeled vehicles. Compared to windshield wipers for cars, three-wheeled vehicle wipers generally have a simpler structure and lower cost, which meets the actual demand for three-wheeled vehicle windshield wipers. Existing three-wheeled vehicle windshield wipers have a relatively simple structure, mainly composed of three parts: 1. Drive component: mostly a 12V low-voltage DC motor providing power; some simpler models are manually cranked (no motor required); 2. Actuation component: including the wiper arm and wiper blade. The wiper arm connects the motor to the wiper blade, and the rubber strip on the wiper blade directly contacts the glass, cleaning through reciprocating motion; 3. Control component: mostly a simple switch (installed on the handlebar or dashboard), supporting on / off or high / low speed adjustment; a few high-end models have an intermittent wiping function. Working principle: After the motor (or manual crank) is started, it transmits power to the wiper arm, which drives the wiper arm to make a fan-shaped reciprocating motion around a fixed axis. The rubber strip on the wiper blade is in close contact with the windshield, and the wiper removes rainwater and dirt from the glass surface during the movement.

[0003] As can be seen from the above, the windshield wiper structure of tricycles needs to be low in overall cost, easy to repair and replace, and the rubber wiper blades need to be replaced individually after wear in order to better adapt to the usage scenarios of tricycles. The current tricycle windshield wiper structure is relatively cumbersome to install, disassemble, repair and replace, so it needs to be improved. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems existing in the prior art.

[0005] This application provides a windshield wiper structure for a three-wheeled vehicle, including a wiper arm body and a wiper blade body for direct contact with the glass for cleaning. The wiper blade body is mounted on the wiper arm body via a detachable mounting assembly. The detachable mounting assembly includes a mounting block connected to the wiper arm body and a mounting seat connected to the wiper blade body. The mounting block is L-shaped, having a mounting surface for the mounting seat to be mounted close to it and a limiting surface for limiting the mounting seat's rotation towards the wiper blade body. A mounting shaft is provided on the mounting surface, and a mounting hole mates with the mounting shaft on the mounting seat. A limiting strip is also provided on the limiting surface to limit the mounting seat from sliding away from the mounting surface after installation.

[0006] Preferably, a U-shaped limiting groove is formed between the limiting strip, the mounting surface, and the limiting surface. During installation, the side of the mounting seat away from the wiper blade body rotates relative to the limiting surface. At this time, the limiting strip does not prevent the mounting hole of the mounting seat from being aligned with the mounting shaft for insertion. After the mounting seat is inserted, the mounting seat is rotated so that part of the mounting seat rotates into the limiting groove, and the limiting strip limits the mounting seat.

[0007] Preferably, the mounting base is configured as a cuboid.

[0008] Preferably, the mounting shaft is vertically fixed on the mounting surface, and its length is set to be greater than the distance between the limiting strip and the mounting surface.

[0009] Preferably, the limiting strip has a beveled surface on the side wall facing the mounting shaft and at the end of the limiting strip away from the limiting surface, which facilitates the installation of the mounting base.

[0010] Preferably, the mounting base has a cross-shaped groove on the side away from the limiting surface for engaging the wiper blade body.

[0011] Preferably, a U-shaped notch is symmetrically opened in the middle of the groove on the side away from the limiting surface of the wiper blade mounting groove.

[0012] Preferably, the mounting block has two rotating mounting holes for rotating connection with the wiper arm body.

[0013] Preferably, the mounting base has several weight-reducing grooves around the mounting hole.

[0014] Preferably, the width of the mounting base is less than or equal to the distance between the limiting strip and the mounting surface, and the difference between the two values ​​is less than 1mm.

[0015] This solution utilizes the aforementioned three-wheeled vehicle windshield wiper structure, employing an L-shaped mounting block and a rotary snap-fit ​​detachable component to achieve tool-free quick assembly and disassembly. During installation, simply align the mounting hole of the mounting base with the mounting shaft of the mounting block, insert it, and rotate it around the shaft. Axial positioning is achieved via a limiting strip, eliminating the need for screwdrivers or other tools. During use, the wiper blade body adheres tightly to the glass surface under the pressure of the wiper arm body, thus partially retaining the mounting base in the limiting groove. The limiting strip and limiting surface further ensure the wiper's function. During disassembly, simply rotate the mounting base in the opposite direction to detach it from the limiting groove and remove it from the mounting shaft. The entire process is smooth, significantly improving replacement efficiency compared to existing screw-fixed or snap-fit ​​structures. It is particularly suitable for three-wheeled vehicle users (such as freight and agricultural vehicle owners) who require self-repair and quick restoration of service. Furthermore, the structure is simple, cost-effective, and highly practical.

[0016] In summary, the structure of this tricycle windshield wiper improves upon existing technologies in the following three ways: 1. By using an L-shaped mounting block and a rotating snap-fit ​​mounting base, the wiper blades can be quickly disassembled and installed without tools, improving replacement efficiency compared to screw-fixed structures; 2. Through the U-shaped limiting groove, the precise clearance fit between the mounting base and the groove (difference <1mm), and the clamping action of the wiper arm, it ensures that there is no loosening or missed wiping during use; 3. The cross-shaped mounting groove is compatible with multiple wiper blade specifications, and the weight-reducing groove lowers costs, fully meeting the needs of freight and agricultural tricycles for easy maintenance and low cost.

[0017] The beneficial effects of this invention will be explained in detail in the embodiments, thereby making the beneficial effects more obvious. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0029] Example 1:

[0030] like Figures 1-8 As shown, a three-wheeled vehicle windshield wiper structure includes a wiper arm body 1 and a wiper blade body 2 for direct contact with the glass for cleaning. In a specific embodiment of this utility model, the wiper blade body 2 is mounted on the wiper arm body 1 via a detachable mounting assembly. The detachable mounting assembly includes a mounting block 3 connected to the wiper arm body 1 and a mounting seat 4 connected to the wiper blade body 2. The mounting block 3 is L-shaped and has a mounting surface 31 for mounting the mounting seat 4 relatively close to it and a limiting surface 32 for limiting the rotation of the mounting seat 4 towards the wiper blade body 2. A mounting shaft 5 is provided on the mounting surface 31, and a mounting hole 6 is provided on the mounting seat 4 to cooperate with the mounting shaft 5. A limiting strip 7 is also provided on the limiting surface 32 to limit the mounting seat 4 from sliding away from the mounting surface 31 after installation.

[0031] In a specific embodiment of this utility model, a U-shaped limiting groove is formed between the limiting strip 7, the mounting surface 31, and the limiting surface 32. During installation, the side of the mounting base 4 away from the wiper blade body 2 rotates relative to the limiting surface 32. At this time, the limiting strip 7 does not obstruct the mounting hole 6 of the mounting base 4 from being aligned with the mounting shaft 5 for insertion. After the mounting base 4 is inserted, the mounting base 4 is rotated so that part of the mounting base 4 is rotated into the limiting groove, and the limiting strip 7 limits the mounting base 4.

[0032] The above-described three-wheeled vehicle windshield wiper structure achieves tool-free quick assembly and disassembly through an L-shaped mounting block 3 and a rotary snap-fit ​​detachable component. During installation, simply align the mounting hole 6 of the mounting base 4 with the mounting shaft 5 of the mounting block 3, insert it, and rotate it around the mounting shaft 5. Axial positioning is achieved through the limiting strip 7, eliminating the need for screwdrivers or other tools. During use, under the pressing force of the wiper arm body 1, the wiper blade body 2 adheres tightly to the glass surface, thus partially holding the mounting base 4 within the limiting groove. The limiting strip 7 and limiting surface 32 further limit its position, ensuring the wiper's function. During disassembly, simply rotate the mounting base 4 in the opposite direction to detach it from the limiting groove and remove it from the mounting shaft 5. The entire process is smooth, improving replacement efficiency and reducing costs compared to existing screw-fixed or snap-fit ​​structures. The U-shaped groove formed by the limiting strip 7, mounting surface 31, and limiting surface 32 provides radial and axial bidirectional constraint on the mounting base 4, preventing it from sliding along the mounting shaft 5 or rotating freely around it.

[0033] In a specific embodiment of this utility model, the mounting base 4 is configured in a cuboid shape. The cuboid-shaped mounting base 4 is convenient to install and use, and provides good positioning during engagement. Figure 3 As shown, the upper left and right sides of the mounting base 4 can be slightly rotated after installation and will be limited by the limiting surface 32 to prevent it from falling out.

[0034] In a specific embodiment of this utility model, the mounting shaft 5 is vertically fixed on the mounting surface 31, and its length is set to be greater than the distance between the limiting strip 7 and the mounting surface 31. The mounting shaft 5 can completely penetrate the mounting hole 6 and extend beyond it, further preventing the mounting base 4 from accidentally coming off.

[0035] In a specific embodiment of this utility model, a beveled surface 8 is provided on the side wall of the limiting strip 7 facing the mounting shaft 5, at the end of the limiting strip 7 away from the limiting surface 32, to facilitate the installation of the mounting base 4. This beveled surface 8 is designed to allow the mounting base 4 to be easily inserted after rotating it a certain angle during installation, further facilitating installation while preventing it from coming out, thus providing a specific position for insertion of the mounting base 4.

[0036] In a specific embodiment of this utility model, the mounting base 4 has several weight-reducing grooves 12 formed around the mounting hole 6. This is used to reduce production costs and decrease the weight of the mounting base 4, facilitating wiper operation.

[0037] In a specific embodiment of this utility model, the width of the mounting base 4 is less than or equal to the distance between the limiting strip 7 and the mounting surface 31, and the difference between the two values ​​is less than 1mm. This extremely small gap can eliminate the lateral sway of the mounting base, ensuring that the wiper blade always fits tightly against the glass during reciprocating motion, without any problems such as misalignment or missed wiping.

[0038] Example 2:

[0039] like Figure 1 and 2 As shown, the difference from the aforementioned embodiment 1 is that, in this specific embodiment of the present invention, the mounting base 4 has a cross-shaped wiper blade mounting groove 9 on the side away from the limiting surface 32 for engaging the wiper blade body 2.

[0040] In a specific embodiment of this utility model, a U-shaped notch 10 is symmetrically opened in the middle of the groove on the side away from the limiting surface 32 of the wiper blade mounting groove 9.

[0041] This solution uses a cross-shaped wiper blade mounting slot 9 to connect with the wiper blade body 2. The multi-directional slot of the cross-shaped slot can be adapted to common T-shaped, U-shaped, and straight-insertion type tricycle wiper blades on the market. Users do not need to match special wiper blades separately, but only need to replace the universal rubber wiper blade according to the wear condition, thus reducing replacement costs. At the same time, the U-shaped notch 10 on the side of the mounting slot away from the limiting surface can guide the wiper blade to quickly snap into place during installation, avoiding damage to the interface caused by misalignment during installation.

[0042] Example 3:

[0043] like Figure 8 As shown, the difference from the aforementioned embodiment 1 is that, in this specific embodiment of the present invention, the mounting block 3 has two rotating mounting holes 11 for rotating connection with the wiper arm body 1.

[0044] The wiper arm body 1 has two wiper arms, which are parallel to each other and each has one end rotatably connected to the mounting block 3. The other end of one wiper arm is rotatably connected to the tricycle, and the other end of the other wiper arm is rotatably connected to a block at its tail end. The block at the tail end is driven by a drive component, thereby causing the wiper arm body 1 to perform a reciprocating wiping motion. This part of the structure is existing technology in the field of wipers. The drive component can be an existing 12V low-voltage DC motor or a manual crank.
