[0023] See below. Figures 1 to 2 Various embodiments of the present disclosure are described in detail.
[0024] Figure 1 A schematic diagram of a wiper device according to an embodiment of the present disclosure is shown. The wiper is generally mounted on the windshield of a vehicle (e.g., a motor vehicle, an electric vehicle, or a hybrid vehicle). The wiper device 100 generally includes a wiper motor 200, a transmission mechanism driven by the wiper motor 200, and a first pivot 101 and a second pivot 102 connected to the transmission mechanism. A first wiper arm and a second wiper arm are connected to the first pivot 101 and the second pivot 102, respectively. Driven by the wiper device 100, the first wiper arm and the second wiper arm reciprocate between an upper reverse position and a lower reverse position to wipe the vehicle's front windshield.
[0025] In the present application, the wiper device further includes a waterproof cover 104. The waterproof cover 104 is disposed above the transmission mechanism, and its upper surface is formed as a water-receiving surface for receiving water entering the cowl box where the wiper device is disposed, and preventing the wiper device from contacting the water. Figure 1-3 As shown in FIG, the waterproof cover 104 is configured to at least partially cover the transmission mechanism to prevent liquids such as rainwater entering the vehicle from corroding the transmission mechanism.
[0026] The waterproof cover 104 is generally formed in a plate shape and is sized to at least partially cover the various components of the wiper device. If the transmission mechanism of the wiper device 100 is a movable mechanism such as a four-bar linkage, the waterproof cover 104 preferably covers the entire motion trajectory of the transmission mechanism. This configuration can achieve comprehensive waterproofing of the wiper device 100.
[0027] The waterproof cover 104 is provided with a first through-hole and a second through-hole (not shown) at each end. The first through-hole and the second through-hole are configured to allow the first pivot 101 and the second pivot 102 to pass through. The shapes of the first through-hole and the second through-hole are configured to correspond to the outer contours of the first pivot 101 and the second pivot 102, respectively, and thus can have a generally circular shape. The first through-hole and the second through-hole are arranged outside the first pivot 101 and the second pivot 102 to achieve the positioning and fixing of the waterproof cover 104. The main body of the waterproof cover 104 extends radially outward from the first through-hole and the second through-hole, covering the transmission mechanism of the wiper device 100.
[0028] like Figure 1 As shown, the first through hole and the second through hole of the waterproof cover 104 are respectively formed with a first fixing portion surrounding the first pivot 101 and a second fixing portion 1 surrounding the second pivot 102. The fixing portion is arranged in a cylindrical shape on the outer peripheral surface of the pivot, extending along the extension direction of the pivot, and is arranged in close contact with the pivot, so as to prevent the pivot from contacting water and prevent water from leaking downward from the edge of the pivot, thereby ensuring the waterproof effect. In another example, a shaft sleeve is provided along the outer peripheral surface of the pivot, and accordingly, the first fixing portion and the second fixing portion are arranged around the shaft sleeve. This does not constitute a specific limitation in the present application.
[0029] In one example, ribs are provided on the inner sides of the first fixing portion and the second fixing portion along the extension direction of the pivot, which can ensure an interference fit between the fixing portion and the pivot, enhance the stability of the connection between the fixing portion and the pivot, and prevent sliding in the axial direction.
[0030] The waterproof cover 104 is preferably made of a hard resin material, which can reduce the weight while ensuring the strength of the waterproof cover, thereby obtaining a light and stable structure. Of course, the waterproof cover 104 can also be made of other materials such as metal, which is not specifically limited in this application.
[0031] In one example, the first fixing portion or the second fixing portion is made of a flexible material. Taking the second fixing portion being made of a flexible material as an example, during the assembly process, the first pivot 101 is first inserted into the first through hole 1 of the waterproof cover 104, and then the position of the waterproof cover 104 is adjusted, and then the second pivot 102 is inserted into the second through hole of the waterproof cover 104. Since the second fixing portion is made of a flexible material, the second pivot 102 and the second through hole can be easily installed and fixed. Specifically, the flexible material forming the first fixing portion or the second fixing portion can be rubber or other suitable materials. Preferably, the portion of the waterproof cover 104 adjacent to the first fixing portion 1043 or the second fixing portion 1044 made of a flexible material is also made of a flexible material to further facilitate assembly.
[0032] The waterproof cover 104 is integrally formed through an injection molding process. Specifically, the main body of the waterproof cover 104, made of a hard resin material, and the fixing portion, made of a flexible material, are integrally formed 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 achieves a better waterproofing effect.
[0033] The waterproof cover 104 is provided with a buckle, which is provided on the side of the waterproof cover opposite to the pivot, that is, below the waterproof cover, and corresponds to the positioning hole on the wiper device. Figure 2 As shown, the waterproof cover 104 includes a first buckle and a second buckle (not shown), which are respectively positioned adjacent to the first through-hole and the second through-hole. Positioning holes that mate with the buckles can be formed on the pivot seat, resulting in a compact structure for the wiper device 100. The buckle design ensures that the waterproof cover is stably fixed to the wiper device 100 and prevents it from falling off the wiper device.
[0034] The number of the first buckle and the second buckle can be one or more. Specifically, the first buckle can be one and the second buckle can be two, but it should be known that they can also be other numbers, and this application does not make specific restrictions.
[0035] like Figure 2 As shown, the waterproof cover 104 of the wiper device according to the present application also at least partially covers the wiper motor 200, thereby preventing water and other fluids from remaining at the position of the wiper motor 200, ensuring the normal operation of the wiper motor.
[0036] Specifically, a raised portion 1045 is formed on the waterproof cover 104, and the raised portion 1045 is used to accommodate the wiper motor 200. Forming the raised portion 1045 on the substantially plate-shaped waterproof cover 104 to accommodate the wiper motor can ensure the compact structure of the wiper device 100 while providing protection for the motor without adding additional space.
[0037] In one example, the shape of the protrusion 1045 substantially matches the armature housing of the wiper motor 200. Such a configuration can facilitate the installation of the waterproof cover.
[0038] like Figure 2 and 3 As shown, a fixing structure is formed on the protrusion 1045, and the fixing structure is fixed to the outer peripheral surface of the armature housing of the wiper motor. By fixing the fixing structure formed on the protrusion 1045 to the motor housing, the waterproof cover 104 can be firmly fixed to prevent it from accidentally falling off.
[0039] Specifically, if Figure 3As shown, the fixing structure 1046 can be configured as a pair of clamping pieces.
[0040] In another example, the fixing structure 1046 is configured as an annular member disposed inside the protrusion 1045 and surrounding the outer peripheral surface of the armature housing of the wiper motor 200. The annular member and the clamping piece can use less material to ensure the fixing effect, thereby saving costs.
[0041] In another example, the fixing structure 1046 may also be formed by extending the protrusion 1045 toward the side surface of the armature housing of the wiper motor, that is, the protrusion 1045 further extends toward the side surface of the motor housing and covers at least a portion of the side surface.
[0042] The fixing structure 1046 is preferably made of the same material as the waterproof cover 104 and is formed integrally with the waterproof cover 104 .
[0043] like Figure 1 As shown, the waterproof cover 104 is configured as a concave shape with an open top. On the side adjacent to the wiper motor 200, its edge rises upward relative to the main body of the waterproof cover 104. On the side opposite the wiper motor 200, its edge folds downward relative to the main body of the waterproof cover 104. This design prevents water and other fluids from flowing toward the wiper motor 200, instead directing them outward from the side opposite the wiper motor 200. Furthermore, the waterproof cover 104 is provided with a drain port 109 to direct water and other fluids out of the waterproof cover 104. This design effectively enhances the waterproofness and drainage properties of the waterproof cover 104.
[0044] like Figure 1 As shown, the drain port 109 is provided on the waterproof cover 104 near the raised portion 1045 to drain the water near the motor 200 in time and prevent it from entering the motor.
[0045] Multiple drain openings may be provided. In addition to drain opening 109, first to fourth drain openings may also be provided. The first and second drain openings are respectively provided adjacent to the first pivot 101 and the second pivot 102 to promptly and appropriately drain fluids such as water that drips near the pivots and prevent them from entering the first pivot 101 and the second pivot 102. The first and second drain openings form a U-shaped cross-section through the bottom and the sidewalls of the waterproof cover 104 on both sides. The U-shaped cross-section opens in the direction opposite to the pivot, and the bottom slopes downward toward the opening of the drain opening.
[0046] The third drain port is formed near the end of the waterproof cover 104 on the side closest to the second pivot 102. The fourth drain port is formed between the second drain port and the wiper motor 200. The sidewalls of the waterproof cover 104 on both sides form a U-shaped cross-section. The third and fourth drain ports both open in opposite directions from the pivot, and their bottoms slope downward toward the opening of the drain ports, thereby directing water out of the wiper device.
[0047] like Figure 1 As shown, a sponge 1049 is provided on the side of the waterproof cover 104 near the motor to prevent collision between the waterproof cover 104 and the wiper motor 200 during vibration and to provide cushioning to ensure 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 collision between the waterproof cover 104 and the wiper motor 200, and this application does not limit this.
[0048] Through the above design, the wiper device of the present application can achieve waterproofing of the wiper motor by covering the wiper motor with a waterproof cover. At the same time, by fixing the waterproof cover on the wiper motor, the stability of the waterproof cover can be enhanced, the waterproof effect of the transmission device can be ensured, and the service life of the wiper device can be increased. In addition, the fixing method of the present application is easy to operate and can achieve simple assembly.
[0049] The vehicle of the present disclosure includes the wiper device as described above and has the advantages thereof.
[0050] In addition, the technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art can also make other combinations between the technical features according to the purpose of the utility model to achieve the purpose of this disclosure.
