[0028] Next, refer to Figures 1 to 8 to describe each embodiment of the present disclosure in detail.
[0029] Figure 1 and 2A schematic diagram of a wiper device according to an embodiment of the present disclosure is shown. The wiper is generally disposed on the windshield of a vehicle (e.g., a motor vehicle, an electric vehicle, a hybrid vehicle, etc.). The wiper device 100 generally includes a wiper motor 200, a transmission mechanism 103 driven by the wiper motor 200, a fixed rod 1031 that supports the transmission mechanism 103 and fixes the wiper motor 200, and a first pivot 101 and a second pivot 102 connected to the transmission structure 103. The first wiper arm and the second wiper arm are respectively connected to the first pivot 101 and the second pivot 102. The first wiper arm and the second wiper arm reciprocate between an upper reverse position and a lower reverse position under the drive of the wiper device 100 to wipe the front glass of the vehicle.
[0030] In the present application, the wiper device further 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 enclosure where the wiper device is arranged, and preventing the wiper device from coming into contact with water. As Figures 1 - 4 shown, the waterproof cover 104 is configured to at least partially cover the transmission mechanism 103 to prevent liquids such as rainwater entering the vehicle from eroding the transmission mechanism.
[0031] The waterproof cover 104 is generally formed in a plate shape, and its size and structure are configured to be suitable for at least partially covering various components of the wiper device. If the transmission mechanism of the wiper device 100 is a movable device such as a four-bar linkage mechanism, etc., the waterproof cover 104 preferably covers the contour of the entire movement trajectory of the transmission mechanism. Such a setting can achieve comprehensive waterproofing of the wiper device 100.
[0032] First through holes 1041 and second through holes 1042 are respectively provided at both ends of the waterproof cover 104. 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 are configured to correspond to the outer contours of the first pivot 101 and the second pivot 102 respectively, and thus may have a generally circular shape. The first through hole 1041 and the second through hole 1042 are sleeved 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 1041 and the second through hole 1042 to cover the transmission mechanism of the wiper device 100.
[0033] As Figure 3As shown, a first fixing portion 1043 surrounding the first pivot 101 and a second fixing portion 1044 surrounding the second pivot 102 are respectively formed circumferentially on the first through hole 1041 and the second through hole 1042 of the waterproof cover 104. The fixing portions are arranged in a cylindrical shape on the outer peripheral surface of the pivot, extend along the extending direction of the pivot, and are arranged in contact with the pivot, so that the pivot can be prevented from contacting water, and water leakage from the edge of the pivot downward can also be prevented, ensuring the waterproof effect. In another example, a bushing is provided on the outer peripheral surface of the pivot, and correspondingly, the first fixing portion and the second fixing portion are arranged around the bushing. The present application does not constitute a specific limitation.
[0034] In one example, ribs are provided on the inner sides of the first fixing portion 1043 and the second fixing portion 1044 along the extending 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.
[0035] The waterproof cover 104 is preferably made of a hard resin material, which can reduce the mass while ensuring the strength of the waterproof cover, resulting in a light and stable structure. Of course, the waterproof cover 104 can also be made of other materials such as metal, and the present application does not make specific limitations.
[0036] In one example, the first fixing portion 1043 or the second fixing portion 1044 is made of a flexible material. Taking the second fixing portion 1044 being made of a flexible material as an example, during the assembly process, first insert the first pivot 101 into the first through hole 1041 of the waterproof cover 104, then adjust the position of the waterproof cover 104, and then insert the second pivot 102 into the second through hole 1042 of the waterproof cover 104. Since the second fixing portion 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 carried out. Specifically, the flexible material forming the first fixing portion 1043 or the second fixing portion 1044 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.
[0037] The waterproof cover 104 is formed integrally by 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 formed integrally by a two-shot injection molding process. Forming the waterproof cover 104 into a single component can obtain a more streamlined structure, simplify the assembly process, and also achieve a better waterproof effect.
[0038] A buckle is provided on the waterproof cover 104. The buckle 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. As Figure 2 、 4As shown in FIGS. 5 and 6, the waterproof cover 104 includes a first buckle 105 and a second buckle 106, which are respectively configured to be disposed adjacent to the first through hole 1041 and the second through hole 1042. The first buckle 105 and the second buckle 106 are respectively disposed adjacent to the first through hole 1041 and the second through hole 1042, so that positioning holes that cooperate with the buckles can be formed on the shaft seat of the pivot, obtaining a compact structure of the wiper device 100. Through the design of the buckles, the waterproof cover can be stably fixed on the wiper device 100 and can prevent it from disengaging from the wiper device.
[0039] The number of the first buckle 105 and the second buckle 106 can be one or more respectively. In Figure 4 the illustrated example, the first buckle 105 is one and the second buckle 106 is two. However, it should be understood that they can also be other numbers, and the present application does not make specific limitations.
[0040] As Figure 2 and 4 shown, the waterproof cover 104 of the wiper device according to the present application further includes a holder 108 and is configured to provide further fixation for the waterproof cover 104.
[0041] In Figure 2 and 4 the illustrated example, the holder 108 is disposed between the first through hole 1041 and the second through hole 1042. The waterproof cover 104 in the present application has a relatively long length. Fixing the waterproof cover 104 to the transmission mechanism 103 through the holder 108 can further improve the stability of the waterproof cover and ensure its effect. In another example, due to requirements such as space, the wiper motor 200 is arranged outside the first pivot and the second pivot instead of between the first pivot and the second pivot. In this case, the holder 108 on the waterproof cover 104 can also be disposed outside the first through hole and the second through hole, and the present application does not make specific limitations.
[0042] In one example, as Figure 2 and 4 shown, the holder 108 is configured as a pair of clamping pieces for clamping the waterproof cover 104 on the fixing rod 1031. The fixing rod 1031 can be configured as a cylindrical tubular member. The holder 108 is disposed on the side of the waterproof cover opposite to the pivot, that is, below the waterproof cover, for clamping the waterproof cover 104 on the outer peripheral surface of the fixing rod.
[0043] Specifically, the holder 108 can be disposed at a position corresponding to the fixing rod 1031 of the transmission mechanism 103 and clamped to the outer peripheral surface of the fixing rod 1031 through the clamping pieces. The fixing rod 1031 is riveted to the first rivet 1011 of the first pivot and / or the second rivet 1021 of the second pivot.
[0044] AsFigure 7 As shown, the holder 108 can also be arranged near the pivot, and is clamped to the outer peripheral surface of the first rivet 1011 of the first pivot and / or the second rivet 1021 of the second pivot 102 through the clamping piece. During the assembly process, the clamping piece undergoes elastic deformation to clamp the fixing rod 1031 or the rivet therein. Such a design can achieve the additional fixation of the waterproof cover 104 with a simple structure and ensure the stability of the waterproof cover. It should be noted that the number of holders 108 can be one, such as clamping on the outer peripheral surface of the fixing rod 1031 or one of the rivets, or can be two or more, for example, two respectively clamping on the outer peripheral surface of the fixing rod 1031 and one of the rivets, two respectively clamping on the outer peripheral surfaces of the first rivet 1011 and the second rivet 1021, two or more clamping on the outer peripheral surface of the fixing rod 1031, or having two or more clamping on the outer peripheral surface of the fixing rod 1031 and one or two clamping on the outer peripheral surface of the rivet at the same time. The present application does not constitute a specific limitation.
[0045] In another example, as Figure 6 shown, a bracket 1032 is provided on the fixing rod 1031, and the holder 108 fixes the waterproof cover 104 to the bracket 1032.
[0046] Specifically, an opening 1033 is formed on the bracket 1032, and the holder 108 is a buckle, and the buckle is inserted into the opening 1033. The bracket 1032 is fixed to the fixing rod 1031 by welding. Such a fixing method is more firm and reliable. Of course, the bracket 1032 can also be fixed to the fixing rod 1031 in other ways, and the present application does not make a specific limitation.
[0047] As Figure 3 shown, the waterproof cover 104 is configured as a concave shape with an open upper part. On the side close to the wiper motor 200, its edge stands upward relative to the main body of the waterproof cover 104. On the side opposite to the wiper motor 200, its edge is folded downward relative to the main body of the waterproof cover 104. Such a design can prevent fluids such as water from flowing towards the wiper motor 200, but will flow out from the side opposite to the wiper motor 200. In addition, the waterproof cover 104 is provided with a drain port 109 to guide fluids such as water outside the waterproof cover 104. By designing the drain port, the waterproofness and drainage of the waterproof cover 104 can be effectively improved.
[0048] The drain openings 109 can be designed in multiple numbers. Among them, the first drain opening 1091 and the second drain opening 1092 are respectively arranged adjacent to the first pivot 101 and the second pivot 102, so as to timely and appropriately drain fluids such as water dripping near the pivot, and prevent it from entering the first pivot 101 and the second pivot 102. The first drain opening 1091 and the second drain opening 1092 form a U-shaped cross-section through the bottom and the edge side walls of the waterproof covers 104 on both sides, which open in the opposite direction of the pivot, and the bottom is formed as a downhill slope towards the opening of the drain opening.
[0049] The third drain opening 1093 is formed at the end of the waterproof cover 104 close to the second pivot 102 on one side. The fourth drain opening 1094 is formed between the second drain opening 1492 and the wiper motor 200. The edge side walls of the waterproof covers 104 on both sides form a U-shaped cross-section. Both the third drain opening 1093 and the fourth drain opening 1094 open in the opposite direction of the pivot, and the bottom is formed as a downhill slope towards the opening of the drain opening, so as to guide the water outside the wiper device.
[0050] As Figure 3 shown, a sponge 1049 is provided on the side of the waterproof cover 104 close to the motor to avoid the waterproof cover 104 colliding with the wiper motor 200 during vibration, and provide buffering to ensure the normal operation of the wiper motor 200. The sponge 1049 can be pasted on the erected edge of the waterproof cover 104. Of course, other buffer materials other than the sponge can also be used to prevent the waterproof cover 104 from colliding with the wiper motor 200, and the present application does not make specific limitations.
[0051] Through the above design, the wiper device of the present application can firmly fix the waterproof cover to the transmission mechanism of the wiper device by arranging additional holding parts on the waterproof cover, which can enhance the stability of the waterproof cover, avoid the accidental detachment of the waterproof cover during the transportation or operation of the wiper device, ensure the waterproof effect of the transmission device, and improve the service life of the wiper device. Moreover, the fixing method of the present application is easy to operate and can achieve simple assembly.
[0052] The vehicle of the present disclosure includes the wiper device as described above and has the advantages of the wiper device.
[0053] In addition, the above-disclosed technical features are not limited to the combinations with other features that have been disclosed. Those skilled in the art can also make other combinations between the technical features according to the purpose of the invention, subject to achieving the purpose of the present disclosure.
