Description

Technical Field

[0001] This utility model relates to the field of cab assembly technology, specifically to a windshield wiper structure for a cab assembly. Background Technology

[0002] The cab assembly is the core control area of ​​automobiles, trucks, and other motor vehicles, integrating the driver, vehicle control systems, and information displays into a single structural unit. It typically includes a steering wheel, instrument panel, various control switches and buttons, pedals (accelerator, brake, clutch), gear shift mechanism, driver's seat, seat belts, airbags, and related core components such as the steering column and brake assist mechanism. The cab assembly not only provides the driver with a direct interface for operating the vehicle (steering, acceleration, braking, gear shifting), but also displays real-time vehicle status information (such as speed, RPM, fuel level, and warning lights). Through its structural design, safety devices (seat belts, airbags), and comfort features (seats, air conditioning, sound insulation), it ensures the safety and operational comfort of the occupants, serving as the central hub for human-machine interaction and driving control of the entire vehicle.

[0003] Rain, snow, hail, and other precipitation can instantly blur the windshield, making it impossible for drivers to see the road conditions, traffic signals, pedestrians, and other vehicles ahead. Windshield wipers are the primary means of clearing these obstacles, but with prolonged use, the rubber of the wipers ages quickly, and uneven pressure leads to incomplete wiping and skipping, affecting overall performance. To address this, we propose a new wiper structure for the driver's cab assembly. Utility Model Content

[0004] The purpose of this invention is to provide a windshield wiper structure for a cab assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A windshield wiper structure for a driver's cab assembly includes: a rotating motor, a protective baffle on the top of the rotating motor, a drive gear on the top of the rotating motor, and a rotating shaft fixedly connected to the top of the drive gear.

The connecting fixing plate is disposed on one side of the surface of the protective baffle, and a plurality of fixing nails are fixedly connected between the connecting fixing plate and the protective baffle.

[0011] Preferably, the cleaning base plate is fixedly connected to one side of the connecting fixing plate, and the cleaning brush is fixedly connected to the back of the cleaning base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The wiper assembly utilizes its own structure and a rotating motor as a base to drive the first adapter rotating block, connecting plate, second adapter rotating block, rotating base, and rotating plate to form a linkage structure that combines with each other to form the basic reciprocating function of the wiper. Furthermore, the wiper assembly can effectively avoid uneven pressure during rotation during use, thereby further improving the functionality of the device. When idle, it can also be combined with the cleaning component to clean the surface of the wiper arm and prevent dirt and insect residue from remaining.

[0014] 2. The basic function of the wiper is achieved through the structure of the wiper assembly. Rotation is achieved through the linkage between a rotating cylinder and a rotating plate. The central axis provides the base for the rotating cylinder. At this point, the first hinge frame, the first rotating shaft, the connecting arm, the second hinge frame, the second rotating shaft, the third hinge frame, and the third rotating shaft are interconnected and linked to form a linkage structure. This structure, in close contact with the front window of the driver's cab assembly, forms a reciprocating fan-shaped linkage structure, thus completing the basic function of the wiper. A dynamic spring is positioned between the third hinge frame and the third rotating shaft, resulting in more even pressure at the connection point, reducing bounce and localized wear. Combined with the floating hinge structure formed by the third hinge frame and the third rotating shaft, the wiper arm at the connection point can more flexibly adapt to localized changes in the curvature of the glass, resulting in more even pressure and thus improving the overall pressure uniformity and service life of the wiper arm.

[0023] 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 described embodiments 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] Example

[0026] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0027] A windshield wiper structure for a cab assembly includes: a rotating motor 1, a protective baffle 2 on the top of the rotating motor 1, a drive gear 3 on the top of the rotating motor 1, and a rotating shaft 4 fixedly connected to the top of the drive gear 3. The drive gear 3 is characterized by having a transmission gear 5 meshing with one side, a corresponding rotating shaft 4 at the bottom of the transmission gear 5, a first connecting rotating block 6 on the top of the transmission gear 5, a connecting plate 7 on the surface of the first connecting rotating block 6, a second connecting rotating block 8 at one end of the connecting plate 7, a rotating base 9 at the bottom of the second connecting rotating block 8, a rotating plate 10 at the bottom of the rotating base 9, a wiper assembly 11 on one side of the rotating plate 10, and a cleaning assembly 12 fixedly connected to one side of the surface of the protective baffle 2.

[0028] In this embodiment, the rotating motor 1 provides a basis for the rotation of the entire device using the rotating shaft 4 and the drive gear 3. The protective baffle 2 can effectively isolate the rotating motor 1 from the top structure, ensuring the safety of the device. The transmission gear 5 will rotate under the action of the drive gear 3. This rotation drives the first transition rotating block 6 to move. At this time, the first transition rotating block 6, the connecting plate 7, the second transition rotating block 8, the rotating base 9, and the rotating plate 10 are linked with the internal structure of the wiper assembly 11 to form a linkage structure. This structure converts the rotational motion of the rotating shaft 4 at the top of the motor into the left and right reciprocating swing (fan-shaped motion) required by the wiper assembly 11 during the rotation process. The wiper assembly 11 will use its own structure to keep the pressure generated during the use of the wiper uniform and combine with the cleaning component 12 to clean the dirt that has been removed during the reciprocating use.

[0029] The wiper assembly 11 includes a rotating cylinder 1101, a rotating central shaft 1102, a first hinge frame 1103, a first rotating shaft 1104, a connecting arm 1105, a second hinge frame 1106, a second rotating shaft 1107, a third hinge frame 1108, a dynamic spring 1109, a third rotating shaft 1110, and a wiper arm 1111. The rotating cylinder 1101 is disposed on one side of the rotating plate 10, the rotating central shaft 1102 is disposed on the inner wall of the rotating cylinder 1101, the first hinge frame 1103 is disposed on one side of the rotating cylinder 1101, and the first rotating shaft 1104 is disposed on the inner wall of the first hinge frame 1103.

[0030] In this embodiment, the wiper assembly 11 can be connected to the rotating plate 10 via the rotating cylinder 1101, and rotate under the action of the rotating central shaft 1102, thereby driving the movement of the first hinge frame 1103 and the internal first rotating shaft 1104, forming a movable foundation for the linkage structure inside the wiper assembly 11.

[0031] The connecting arm 1105 is rotatably connected to the inner wall of the first hinge frame 1103, the second hinge frame 1106 is fixedly connected to the top of the connecting arm 1105, and the second rotating shaft 1107 is rotatably connected to the inner wall of the second hinge frame 1106.

[0032] In this embodiment, the connecting arm 1105, the second hinge frame 1106, the second rotating shaft 1107, the rotating cylinder 1101, the rotating central shaft 1102, the first hinge frame 1103, and the first rotating shaft 1104 are linked together to form a fan-shaped movement by aligning the movement trajectory of the connecting arm 1105 with the front window surface of the cab assembly, thereby providing a basic movement trajectory for the wiper arm 1111's wiper function.

[0033] The third hinge frame 1108 is fixedly connected to the surface of the second rotating shaft 1107, and multiple dynamic springs 1109 are fixedly connected to the inner wall of the third hinge frame 1108. The third rotating shaft 1110 is disposed on the inner wall of the third hinge frame 1108, and the wiper arm 1111 is fixedly connected to the surface of the third rotating shaft 1110. The dynamic springs 1109 are disposed between the inner wall of the third hinge frame 1108 and the wiper arm 1111.

[0034] In this embodiment, the third hinge frame 1108 and the third rotating shaft 1110 are combined with each other, and the wiper arm 1111 installed on the surface of the third rotating shaft 1110 forms a floating hinge structure, which helps the wiper arm 1111 to combine with the dynamic spring 1109 during use, so that the wiper blade can adapt more flexibly to the local curvature changes of the glass, the pressure is more uniform, and the vibration and local wear are reduced.

[0035] The cleaning assembly 12 includes a connecting fixing plate 1201, fixing nails 1202, a cleaning base plate 1203, and a cleaning brush 1204. The connecting fixing plate 1201 is disposed on one side of the surface of the protective baffle 2, and a plurality of fixing nails 1202 are fixedly connected between the connecting fixing plate 1201 and the protective baffle 2.

[0036] In this embodiment, the cleaning component 12 is fixed to one side of the surface of the protective baffle 2 by the connecting fixing plate 1201 and the fixing nail 1202, so as to ensure that the wiper arm 1111 will pass through the overall usage trajectory, and provide a fixed position base for the cleaning component 12 to clean the wiper arm 1111.

[0037] The cleaning base plate 1203 is fixedly connected to one side of the connecting fixing plate 1201, and the cleaning brush 1204 is fixedly connected to the back of the cleaning base plate 1203.

[0038] In this embodiment, the positions of the cleaning base plate 1203 and the cleaning brush 1204 are matched with the bottom position of the fan-shaped scraping of dirt by the wiper arm 1111. Each time the wiper returns to its original position, it automatically scrapes the wiper blade rubber strip to remove attached dirt and insect residue, thus extending the rubber strip's lifespan.

[0039] Working principle: This device uses a rotating motor 1 to drive a rotating shaft 4, which in turn drives a drive gear 3, providing the rotational basis for the entire device. The protective baffle 2 effectively isolates the rotating motor 1 from the top gear for easy installation. The rotation of the drive gear 3 drives the transmission gear 5. Because the transmission gear 5 is larger than the drive gear 3, the drive gear 3 needs to rotate multiple times to drive the transmission gear 5 to complete one revolution, thus achieving a speed reduction effect during rotation. The internal structures of the first rotating block 6, connecting plate 7, second rotating block 8, rotating base 9, rotating plate 10, and wiper assembly 11 at the top of the transmission gear 5 are described. A linkage structure is formed, which converts the rotational motion of the rotating shaft 4 at the top of the motor into the left-right reciprocating oscillation (fan-shaped motion) required by the wiper assembly 11 during rotation. At the same time, the wiper assembly 11 combines its own structure with this linkage structure to form the basic reciprocating wiper function. Furthermore, the wiper assembly 11 can effectively avoid uneven pressure during rotation during use, thereby further improving the functionality of the device. When idle, it combines with the cleaning component 12 to clean the surface of the wiper arm 1111, preventing dirt and insect residue from remaining, thereby further improving the service life of the device.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
