Description

Technical Field

[0001] This disclosure pertains to the field of vehicle windshield wipers, and specifically relates to a windshield wiper device for a vehicle and the vehicle itself. Background Technology

[0002] Windshield wipers are an essential part of a vehicle. They are mainly used to clear rainwater, snow, or dust from the windshield in adverse weather conditions (such as rain, snow, or sandstorms), thus ensuring the driver's visibility is not obstructed and guaranteeing driving safety.

[0003] During rain, car washes, or windshield cleaning, wiper components may come into contact with water, which can cause corrosion of metal parts such as the linkage mechanism, affecting its lifespan. A waterproof cover can be installed above the linkage mechanism to prevent water contact. Existing wiper waterproofing solutions typically waterproof different components separately. However, current solutions suffer from problems such as only providing localized waterproofing and complex assembly. Summary of the Invention

[0026] See below Figures 1 to 6 The various embodiments of this disclosure are described in detail.

[0027] Figure 1 A schematic diagram of a windshield wiper device according to an embodiment of the present disclosure is shown. Windshield wipers are generally mounted on the windshield of a vehicle (e.g., a motor vehicle, an electric vehicle, or a hybrid vehicle). The windshield wiper device 100 typically includes a wiper motor 200, a transmission mechanism 103 driven by the wiper motor 200, a mounting rod 1031 supporting the transmission mechanism 103 and fixing the wiper motor 200, and a first pivot 101 and a second pivot 102 connected to the transmission mechanism 103. A first wiper arm and a second wiper arm are respectively connected to the first pivot 101 and the second pivot 102. Driven by the windshield wiper device 100, the first wiper arm and the second wiper arm reciprocate between an up-reverse position and a down-reverse position to wipe the windshield of the vehicle.

[0028] In this application, the wiper assembly also includes a waterproof cover 104. The waterproof cover 104 is disposed above the transmission mechanism 103, and its upper surface is formed as a water-receiving surface for receiving water entering the front bulkhead housing on which the wiper assembly is disposed, and for preventing the wiper assembly from contacting water. Figure 1-3 As shown, the waterproof cover 104 is configured to at least partially cover the transmission mechanism 103 to prevent rainwater or other liquids entering the vehicle from corroding the transmission mechanism.

[0029] The waterproof cover 104 is generally plate-shaped and sized to at least partially cover the various components of the wiper assembly. If the drive mechanism of the wiper assembly 100 is a moving device such as a four-bar linkage, the waterproof cover 104 preferably covers the entire outline of the movement trajectory of the drive mechanism, thereby achieving complete waterproofing of the wiper assembly 100.

[0030] The waterproof cover 104 has a first through hole 1041 and a second through hole 1042 at both ends, respectively. The first through hole 1041 and the second through hole 1042 are respectively configured to allow the first pivot 101 and the second pivot 102 to pass through. The shapes of the first through hole 1041 and the second through hole 1042 correspond to the outer contours of the first pivot 101 and the second pivot 102, respectively, and therefore can have a roughly circular shape. The first through hole 1041 and the second through hole 1042 are fitted onto the outside of the first pivot 101 and the second pivot 102 to achieve the positioning and fixation of the waterproof cover 104. The main body of the waterproof cover 104 extends radially outward from the first through hole 1041 and the second through hole 1042, covering the transmission mechanism of the wiper device 100.

[0031] like Figure 3 , 5 As shown in Figure 6, the first through hole 1041 and the second through hole 1042 of the waterproof cover 104 are respectively provided with a first fixing part 1043 surrounding the first pivot 101 and a second fixing part 1044 surrounding the second pivot 102. The fixing parts are cylindrically disposed on the outer peripheral surface of the pivot, extending along the extension direction of the pivot, and are arranged in close contact with the pivot, thereby preventing the pivot from contacting water and preventing water from seeping downward from the edge of the pivot, ensuring the waterproof effect. In another example, a bushing is provided along the outer peripheral surface of the pivot, and correspondingly, the first fixing part and the second fixing part are disposed around the bushing. This application does not constitute a specific limitation.

[0032] In one example, the inner sides of the first fixing part 1043 and the second fixing part 1044 are provided with ribs along the extension direction of the pivot, which can ensure the interference fit between the fixing part and the pivot, enhance the stability of the connection between the fixing part and the pivot, and prevent sliding in the axial direction.

[0033] The waterproof cover 104 is preferably made of a rigid resin material, which can reduce weight while ensuring the strength of the waterproof cover, resulting in a lightweight and stable structure. Of course, the waterproof cover 104 can also be made of other materials such as metal, and this application does not make a specific limitation.

[0034] In one example, such as Figure 6 As shown, the first fixing part 1043 or the second fixing part 1044 is made of a flexible material. Taking the second fixing part 1044 as an example, during assembly, the first pivot 101 is first inserted into the first through hole 1041 of the waterproof cover 104, then the position of the waterproof cover 104 is adjusted, and then the second pivot 102 is inserted into the second through hole 1042 of the waterproof cover 104. Since the second fixing part 1044 is made of a flexible material, the installation and fixation between the second pivot 102 and the second through hole 1042 can be easily performed. Specifically, the flexible material forming the first fixing part 1043 or the second fixing part 1044 can be rubber or other suitable materials. Preferably, the portion of the waterproof cover 104 adjacent to the first fixing part 1043 or the second fixing part 1044 made of flexible material is also made of flexible material to further facilitate assembly.

[0035] The waterproof cover 104 is formed as a single unit through injection molding. Specifically, the main body of the waterproof cover 104, made of rigid resin material, and the fixing part, made of flexible material, are formed as a single unit through a secondary injection molding process. Forming the waterproof cover 104 as a single component results in a more streamlined structure, simplifies the assembly process, and also achieves better waterproof performance.

[0036] The waterproof cover 104 is equipped with a latch, which is located on the side of the waterproof cover opposite to the pivot, i.e., on the bottom of the waterproof cover, and corresponds to the positioning hole on the wiper assembly. For example... Figure 2 and 3 As shown, the waterproof cover 104 includes a first snap fastener 105 and a second snap fastener 106, which are respectively configured adjacent to the first through hole 1041 and the second through hole 1042. The first snap fastener 105 and the second snap fastener 106, respectively positioned adjacent to the first through hole 1041 and the second through hole 1042, allow the positioning holes that engage with the snap fasteners to be formed on the pivot's bearing, resulting in a compact structure for the wiper assembly 100. The snap fastener design securely fixes the waterproof cover to the wiper assembly 100 and prevents it from detaching from the wiper assembly.

[0037] The number of first buckles 105 and second buckles 106 can be one or more each. Figure 4 In the example shown, there is one first buckle 105 and two second buckles 106, but it should be understood that there may be other quantities, and this application does not impose any specific restrictions.

[0038] like Figure 3 As shown, the waterproof cover 104 is configured as a concave shape with an open upper part. On the side adjacent to the wiper motor 200, its edge rises upward relative to the main body of the waterproof cover 104, while on the side opposite to the wiper motor 200, its edge folds downward relative to the main body of the waterproof cover 104. This design prevents fluids such as water from flowing towards the wiper motor 200, instead directing them to flow out from the side opposite the wiper motor 200. Furthermore, the waterproof cover 104 is provided with a drain outlet to guide fluids such as water to the outside of the waterproof cover 104. By designing the drain outlet, the waterproofness and drainage performance of the waterproof cover 104 can be effectively improved.

[0039] Multiple drain outlets can be designed. The first drain outlet 1091 and the second drain outlet 1092 are respectively located near the first pivot 101 and the second pivot 102 to promptly and appropriately drain water and other fluids dripping near the pivots, preventing them from entering the first pivot 101 and the second pivot 102. The first drain outlet 1091 and the second drain outlet 1092 form a U-shaped cross-section through the edge sidewalls of the waterproof cover 104 on both sides of their bottom, opening in the opposite direction to the pivots, and their bottoms slope downwards towards the openings of the drain outlets.

[0040] The third drain outlet 1093 is formed at the end of the waterproof cover 104 near the second pivot 102. The fourth drain outlet 1094 is formed between the second drain outlet 1492 and the wiper motor 200. The edge sidewalls of the waterproof cover 104 on both sides form a U-shaped cross-section. The third drain outlet 1093 and the fourth drain outlet 1094 both open in opposite directions toward the pivot, and their bottoms slope downward toward the openings of the drain outlets, thereby guiding water out of the wiper assembly.

[0041] like Figure 3 As shown, the waterproof cover 104 has a sponge 1049 on the side near the motor to prevent the waterproof cover 104 from colliding with the wiper motor 200 during vibration and to provide cushioning, ensuring the normal operation of the wiper motor 200. The sponge 1049 can be attached to the raised edge of the waterproof cover 104. Of course, other cushioning materials besides sponge can also be used to prevent the waterproof cover 104 from colliding with the wiper motor 200; this application does not make specific limitations.

[0042] like Figure 4 As shown, a reinforcing structure can also be formed on the main body of the waterproof cover 104 to improve the strength of the waterproof cover 104 and prevent it from deforming.

[0043] Through the above design, the wiper device of this application can effectively prevent water and other fluids from flowing into the transmission mechanism and other parts of the wiper device, and can discharge the fluid in a timely manner, exhibiting excellent drainage performance, thereby ensuring the dryness of these areas and improving the service life of the wiper device. Moreover, the waterproof cover design of this application is easy to assemble, which can effectively reduce the complexity of assembly.

[0044] The vehicle disclosed herein includes the wiper device as described above and has the advantages of the wiper device.

[0045] Furthermore, the technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention, in order to achieve the purpose of this disclosure.
