Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle accessories, in particular to a vehicle cover plate assembly. BACKGROUND

[0002] The ventilation cover plate is a part for isolating the cabin from the outside world, covering the drain groove of the vehicle body and connecting the cover between the front windshield and the engine cabin cover. A process hole is provided on the existing ventilation cover plate, and a wiper shaft is arranged in the process hole to complete the installation of the wiper shaft. In order to ensure the assembly of the wiper shaft and the process hole, a sufficient gap needs to be designed between the process hole and the wiper shaft. An annular sealing member is usually installed in the gap between the process hole and the wiper shaft to prevent rainwater outside the ventilation cover plate from flowing into the inside of the ventilation cover plate through the process hole. The annular sealing member is usually made of a deformable material such as soft rubber or rubber, and an installation hole is formed on the inner side of the annular sealing member. The wiper shaft is arranged in the installation hole, and the outer periphery of the wiper shaft abuts against the inner wall of the installation hole to achieve sealing. The outer side of the annular sealing member is sealingly connected with the inner wall of the process hole, so that the annular sealing member can seal the gap between the process hole and the wiper shaft.

[0003] However, when the wiper shaft and the process hole are assembled, due to assembly errors and their own processing errors, it is difficult to coaxially arrange the wiper shaft and the process hole, that is, the wiper shaft will be offset in the process hole. The material of the annular sealing member is soft and easy to deform. When the offset amount of the wiper shaft is large, the annular sealing member will be deformed unevenly. When the deformation amount of each position in the peripheral region of the installation hole is large, the annular sealing member will be crushed towards the offset direction of the wiper shaft, resulting in deformation of the installation hole and mismatching with the wiper shaft. A gap is formed between the inner wall of the installation hole and the outer periphery of the wiper shaft, which eventually leads to failure of the annular sealing member to seal the wiper shaft, affecting the sealing performance of the vehicle ventilation cover plate.

DETAILED DESCRIPTION

[0027] In order to enable the above-mentioned objects, features and advantages of the present application to be clearer, the following will further describe the solutions of the present application. It should be explained that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in different ways from those described herein without departing from the scope of the present application. It is apparent that the embodiments described in the specification are only a part of the embodiments of the present application, and not all the embodiments.

[0029] With reference to Figures 1 to 4 As shown in the drawings, the embodiments of the present application provide a vehicle cover assembly, which comprises a ventilation cover 1, a wiper shaft 2 and a sealing ring 3. The ventilation cover 1 is provided with a process hole 11, and the wiper shaft 2 is arranged in the process hole 11. The sealing ring 3 comprises an inner frame 31 and a soft connecting part 32, both of which are arranged outside the wiper shaft 2. The end of the soft connecting part 32 is provided with an abutting lip 322 which is sealingly connected with the edge of the process hole 11, and the other end is provided with a sealing lip 321 which is sealingly abutted with the wiper shaft 2. The inner frame 31 is fixedly connected to the end of the soft connecting part 32 provided with the sealing lip 321, so as to support the sealing lip 321 and make the sealing lip 321 sealingly abut with the wiper shaft 2 at all times.

[0030] Firstly, the ventilation cover 1 is a part for isolating the cabin from the outside world, which is a covering part covering the drain groove of the vehicle body and connecting between the front windshield and the engine cabin cover. The existing ventilation cover 1 is provided with a process hole 11, and the wiper shaft 2 is arranged in the process hole 11, so that the wiper shaft 2 can be exposed outside the ventilation cover 1. A sufficient gap is designed between the wiper shaft 2 and the inner wall of the process hole 11 to ensure the assembly and adapt to the manufacturing error of the wiper shaft 2 and the ventilation cover 1, and the sealing ring 3 is installed between the wiper shaft 2 and the inner wall of the ventilation cover 1.

[0031] The inner frame 31 can be selected as a ring structure or a hollow rectangular frame structure, and the elastic modulus of the inner frame 31 is greater than that of the soft connecting part 32, i.e. the inner frame 31 is a rigid part relative to the soft connecting part 32, so that when the inner frame 31 moves relative to the soft connecting part 32, the sealing lip 321 can move with the inner frame 31 without deforming.

[0032] The soft connecting part 32 can be made of rubber or soft rubber, and is arranged around the wiper shaft 2 to form a ring-like structure. The soft connecting part 32 is connected to the inner frame 31 at one end in the radial direction of the wiper shaft 2, and the other end can be provided with a clamping groove. The part of the vent cover 1 at the edge of the process hole 11 can be clamped in the clamping groove to clamp the soft connecting part 32 in the process hole 11. The soft connecting part 32 extends away from the wiper shaft 2 to form an abutting lip 322, which tightly abuts the vent cover 1 on the side of the wiper shaft 2 in the axial direction, so that the abutting lip 322 is in sealing abutment with the vent cover 1.

[0033] The end of the soft connecting part 32 near the wiper shaft 2 extends towards the wiper shaft 2 to form a sealing lip 321, which extends to the inside of the inner frame 31. The side edge of the sealing lip 321 away from the inner frame 31 in the axial direction of the wiper shaft 2 can be provided with a fitting hole, which is matched in shape and size with the cross-sectional shape and size of the wiper shaft 2. The size of the fitting hole is smaller than the cross-sectional size of the wiper shaft 2, so that when the wiper shaft 2 is fitted in the fitting hole, the inner wall of the fitting hole will fit the outer periphery of the wiper shaft 2, that is, the side edge of the sealing lip 321 away from the inner frame 31 will always abut the outer periphery of the wiper shaft 2, so that the sealing lip 321 is in sealing connection with the outer periphery of the wiper shaft 2.

[0034] In the design of the wiper shaft 2 and the vent cover 1, the wiper shaft 2 should be located at the center of the process hole 11. When the sealing ring 3 is installed in the process hole 11, the fitting hole formed by the sealing lip 321 should also be at the center of the process hole 11 so that the wiper shaft 2 can be directly opposite the fitting hole. However, there are manufacturing errors in the sealing ring 3 itself, the wiper shaft 2 and the vent cover 1, and the wiper shaft 2 and the process hole 11 when they are assembled, so that when the wiper shaft 2 is fitted in the process hole 11, there is a deviation between the wiper shaft 2 and the center of the process hole 11, that is, there is a deviation in the radial direction of the process hole 11 between the fitting hole of the wiper shaft 2 and the sealing ring 3 in the process hole 11. If there is no inner frame 31, the deviation of the wiper shaft 2 will cause a part of the sealing lip 321 to deform in the direction of the deviation of the wiper shaft 2. When the deviation of the wiper shaft 2 is large, the soft connecting part 32 will deform in the radial direction of the wiper shaft 2, and the deformation of the soft connecting part 32 will pull the edge of the sealing lip 321, causing the fitting hole to deform and not match the wiper shaft 2, so that when the wiper shaft 2 is fitted in the fitting hole, a gap is formed between the sealing lip 321 and the wiper shaft 2, and sealing cannot be achieved.

[0035] But the sealing ring 3 provided by the application, when the inner skeleton 31 moves relative to the soft connecting part 32, the sealing lip 321 can move with the inner skeleton 31, the distance between the side edge of the sealing lip 321 away from the inner skeleton 31 and the inner skeleton 31 can remain stable, so that the shape and size of the assembly hole remain stable, that is, the deformation of the soft connecting part 32 outside the inner skeleton 31 will not drive the deformation of the sealing lip 321; when the wiper shaft 2 has a large offset, the wiper shaft 2 will contact the inner skeleton 31 and push the inner skeleton 31 to move in the process hole 11, the inner skeleton 31 keeps the shape and size of the sealing lip 321 stable, so that the shape and size of the assembly hole formed by the sealing lip 321 can always match the wiper shaft 2, so that when the wiper shaft 2 is inserted in the assembly hole, the sealing lip 321 can always abut against the outer circumferential surface of the wiper shaft 2.

[0036] The above-mentioned wiper shaft 2 includes a shaft sleeve and a shaft rod, the shaft rod is rotatably inserted in the shaft sleeve, and the end of the shaft rod is installed with a wiper. When the wiper rotates, the shaft rod of the wiper shaft 2 rotates relative to the shaft sleeve, the shaft sleeve and the shaft rod are inserted in the assembly hole formed by the sealing lip 321, and the sealing lip 321 abuts against the shaft sleeve, so that when the wiper rotates, the rotation of the shaft rod will not distort the sealing lip 321. The vehicle will vibrate when driving, and the wiper will also vibrate when rotating. The wiper shaft 2 may be offset in the axial direction of the process hole 11 due to vibration, at which time the movement of the wiper shaft 2 will push the inner skeleton 31 to move, so that the sealing lip 321 moves together with the inner skeleton 31 and keeps sealing abutment with the wiper shaft 2.

[0037] The vehicle cover assembly provided by the application is used in practice, the wiper shaft 2 is inserted in the process hole 11, the sealing ring 3 is sleeved on the wiper shaft 2, the soft connecting part 32 is installed in the process hole 11, the abutment lip 322 is in sealing abutment with the ventilation cover plate 1, the inner skeleton 31 is sleeved on the outer side of the wiper shaft 2, and the sealing lip 321 is in sealing abutment with the outer circumferential surface of the wiper shaft 2. When the wiper shaft 2 is offset in the process hole 11, the wiper shaft 2 will push the inner skeleton 31 to move, the sealing lip 321 moves together with the inner skeleton 31, so that the shape of the sealing lip 321 remains stable, to ensure that the sealing lip 321 always abuts against the wiper shaft 2.

[0038] The vehicle cover assembly provided by the application comprises a ventilation cover plate 1, a wiper shaft 2 and a sealing ring 3. The ventilation cover plate 1 is provided with a process hole 11, and the wiper shaft 2 is arranged in the process hole 11. The sealing ring 3 comprises an inner frame 31 and a soft connecting part 32, the inner frame 31 is arranged outside the wiper shaft 2, the end of the soft connecting part 32 is provided with an abutting lip 322 which is sealingly connected with the edge of the process hole 11, and the other end of the soft connecting part 32 is provided with a sealing lip 321 which is sealingly abutted with the wiper shaft 2. The inner frame 31 is fixedly connected with the end of the soft connecting part 32 which is provided with the sealing lip 321, so as to support the sealing lip 321 and make the sealing lip 321 always sealingly abut with the wiper shaft 2. When the wiper shaft 2 is deviated, the inner frame 31 is pushed to move the sealing lip 321 as a whole, that is, the deformation of the soft connecting part 32 outside the inner frame 31 will not cause the deformation of the sealing lip 321, so that the shape and size of the sealing lip 321 always maintain the matching relationship with the wiper shaft 2. The deviation of the wiper shaft 2 will not affect the sealing connection between the sealing ring 3 and the wiper shaft 2, and the sealing performance of the vehicle cover assembly is improved.

[0039] Referring to Figures 1 to 4 In some embodiments, the end of the soft connecting part 32 away from the wiper shaft 2 is fixedly connected with an outer frame 33, the outer frame 33 is clamped to the edge of the process hole 11 and supports the abutting lip 322. In this way, the outer frame 33 can support the end of the soft connecting part 32 away from the wiper shaft 2, avoid the deformation of the end of the soft connecting part 32 away from the wiper shaft 2 caused by the movement of the inner frame 31, and cause the gap between the soft connecting part 32 and the process hole 11, so as to improve the stability of the sealing connection between the sealing ring 3 and the process hole 11.

[0040] Specifically, the outer frame 33 can be selected as a ring structure or a hollow rectangular frame structure, and the size of the inner frame 31 is smaller than the size of the outer frame 33, so that the inner frame 31 can be arranged inside the outer frame 33. When the wiper shaft 2 is arranged in the inner frame 31, the inner frame 31 and the outer frame 33 are arranged around the wiper shaft 2. The outer frame 33 can be arranged at the end of the soft connecting part 32 away from the wiper shaft 2, and the abutting lip 322 is formed on the side of the outer frame 33 away from the wiper shaft 2. Of course, the outer frame 33 can also have a spacing with the abutting lip 322.

[0041] The outer frame 33 can be provided with a clamping groove on the side away from the inner frame 31 in the radial direction of the wiper shaft 2. The part of the ventilation cover plate 1 at the edge of the process hole 11 is clamped with the clamping groove and abuts with the inner wall of the clamping groove, so that the outer frame 33 is sealingly connected with the process hole 11. Of course, the shape of the outer frame 33 can be consistent with the process hole 11, the size of the outer frame 33 is slightly larger than the process hole 11, and the outer frame 33 is installed in the process hole 11 by elastic deformation of the outer frame 33, so that the surface of the outer frame 33 is tightly abutted with the inner wall of the process hole 11, so as to install the outer frame 33 in the process hole 11.

[0042] Referring to Figures 1 to 4 As shown in the drawings, in some embodiments, the outer frame 33 includes an outer ring body 331 and a clamping portion 332, the outer ring body 331 is fixedly connected with the soft connecting portion 32, and the clamping portion 332 is connected to the outer ring body 331 and clamped to the edge of the process hole 11. In this way, by clamping connection of the clamping portion 332 and the ventilation cover plate 1 at the edge of the process hole 11, the sealing ring 3 can be conveniently installed in the process hole 11.

[0043] Specifically, the outer ring body 331 can be selected as a ring-shaped support, the outer ring body 331 is connected to the soft connecting portion 32 on one side of the wiper shaft 2 in the axial direction, and the clamping portion 332 is connected to the outer ring body 331 on the side of the wiper shaft 2 in the axial direction away from the soft connecting portion 32. The clamping portion 332 can be selected as a hook, the hook has a hook joint spaced from the outer ring body 331, and a space between the hook joint and the outer ring body 331 forms a clamping space. By clamping the ventilation cover plate 1 at the edge of the process hole 11 into the clamping space, the clamping connection of the clamping portion 332 and the ventilation cover plate 1 at the edge of the process hole 11 can be completed.

[0044] Of course, the clamping portion 332 can also be connected to the side of the outer ring body 331 away from the inner frame 31, and the clamping portion 332 includes two elastic blocks, the two elastic blocks are arranged in the axial direction of the wiper shaft 2. The ventilation cover plate 1 at the edge of the process hole 11 is clamped between the two elastic blocks, thereby completing the clamping connection of the clamping portion 332 and the ventilation cover plate 1 at the edge of the process hole 11.

[0045] Referring to Figures 1 to 4 As shown in the drawings, in some embodiments, the number of clamping portions 332 is multiple, and the multiple clamping portions 332 are arranged in the direction around the wiper shaft 2. In this way, the multiple clamping portions 332 are clamped with the ventilation cover plate 1 at the edge of the process hole 11, so that the sealing ring 3 has multiple connection points with the process hole 11, thereby improving the stability of the connection between the sealing ring 3 and the process hole 11.

[0046] Specifically, when the clamping portion 332 is a hook, the number of hooks is multiple, and the multiple hooks are arranged in the direction around the wiper shaft 2, so that the multiple hooks can be clamped and connected with multiple positions of the ventilation cover plate 1 at the edge of the process hole 11. When the clamping portion 332 includes two elastic blocks, the two elastic blocks form a clamping block group, the number of clamping block groups is multiple, and the multiple clamping block groups are arranged in the direction around the wiper shaft 2, so that multiple positions of the ventilation cover plate 1 at the edge of the process hole 11 can be clamped between the two elastic blocks of the multiple clamping block groups.

[0047] In some embodiments, the clamping portion 332 extends along a direction around the wiper shaft 2 to form a ring structure. In this way, the ring-shaped clamping portion 332 increases the contact area of the clamping portion 332 with the vent cover plate 1 at the edge of the process hole 11, thereby improving the stability of the sealing ring 3 in the clamping connection with the process hole 11.

[0048] Specifically, the clamping portion 332 can be selected to include a ring-shaped plate connected to the outer ring body 331 on a side of the wiper shaft 2 axially away from the flexible connecting portion 32, and the ring-shaped plate is provided with a protrusion extending along a direction around the wiper shaft 2 to form a ring structure, and the protrusion is spaced apart from the outer ring body 331, and the vent cover plate 1 at the edge of the process hole 11 is clamped into the space between the protrusion and the outer ring body 331.

[0049] Of course, the clamping portion 332 can also be selected to include two elastic blocks extending along a direction around the wiper shaft 2 to form a ring structure, and the two elastic blocks and the outer ring body 331 together form a ring-shaped clamping groove, and the vent cover plate 1 at the edge of the process hole 11 is clamped into the ring-shaped clamping groove.

[0050] Referring to Figures 1 to 4 In some embodiments, the clamping portion 332 includes a plate body 333 and a protrusion 334, the plate body 333 is connected to the outer ring body 331 and extends along the axial direction of the wiper shaft 2, and the protrusion 334 is provided on one side of the plate body 333, and the protrusion 334, the plate body 333 and the outer ring body 331 form a clamping groove, so that the clamping portion 332 is clamped at the edge of the process hole 11. In this way, the plate body 333 and the protrusion 334 have a simple structure and low manufacturing cost, and when the clamping portion 332 is clamped with the vent cover plate 1 at the process hole 11, the protrusion 334 and the outer ring body 331 can be attached to each other, so that the connection between the clamping portion 332 and the vent cover plate 1 remains temperature.

[0051] Specifically, the plate body 333 extends along the axial direction of the wiper shaft 2 away from the outer ring body 331, and the end of the plate body 333 away from the outer ring body 331 is provided with a protrusion 334, and the protrusion 334 is provided on the side of the plate body 333 away from the inner skeleton 31 in the radial direction of the wiper shaft 2. At least one of the plate body 333 and the protrusion 334 is elastic, and the protrusion 334 and the outer ring body 331 are spaced apart from each other to form a clamping groove between the protrusion 334 and the outer ring body 331; it can be selected that in the axial direction of the wiper shaft 2, the size of the clamping groove is smaller than the size of the vent cover plate 1 at the edge of the process hole 11, and the clamping portion 332 is clamped with the vent cover plate 1 by elastic deformation of the plate body 333 or the protrusion 334 to tightly abut the vent cover plate 1, thereby sealingly connecting the clamping portion 332 with the vent cover plate 1.

[0052] Referring to Figures 1 to 4As shown, in some embodiments, the cross section of the soft connecting portion 32 is wavy. In this way, the wavy soft connecting portion 32 can improve the stability of the soft connecting portion 32 in the axial direction of the wiper shaft 2, and will not affect the deformation of the soft connecting portion 32 in the radial direction of the wiper shaft 2.

[0053] Specifically, the cross section of the soft connecting portion 32 arranged in the radial direction of the wiper shaft 2 and perpendicular to the circumferential direction of the wiper shaft 2 is wavy. The wavy structure can include at least one wave structure, and the wave structure includes two panel portions arranged at an angle to each other, and the two panel portions are connected to each other at one end close to each other, so that the two panel portions form a wave crest. Of course, the wavy soft connecting portion 32 can include a plurality of wave structures arranged in the radial direction of the wiper shaft 2. The wavy structure of the soft connecting portion 32 is between the sealing lip 321 and the abutting lip 322.

[0054] Referring to Figures 1 to 4 As shown, in some embodiments, the soft connecting portion 32 includes a first side surface 341 close to the wiper shaft 2, and the inner skeleton 31 includes an inner ring body 311 connected to the first side surface 341.

[0055] In this way, the inner skeleton 31 and the soft connecting portion 32 have a larger contact area, which improves the connection stability of the inner skeleton 31 and the soft connecting portion 32, and improves the support effect of the inner skeleton 31 on the soft connecting portion 32.

[0056] Specifically, the wavy soft connecting portion 32 has a first side surface 341 on the side facing the wiper shaft 2 in the radial direction of the wiper shaft 2, and the inner skeleton 31 has a cylindrical structure extending in the axial direction of the wiper shaft 2, and the outer side surface of the cylindrical structure is connected to the first side surface 341. When the soft connecting portion 32 has a planar structure, and the inner skeleton 31 is attached to the soft connecting portion 32, due to the limited space between the process hole 11 and the wiper shaft 2, the size of the inner skeleton 31 in the radial direction of the wiper shaft 2 is limited. The side of the wavy soft connecting portion 32 facing the wiper shaft 2 is an inclined surface, and under the condition that the inner skeleton 31 occupies the same space in the radial direction of the wiper shaft 2, the inner skeleton 31 can extend along the inclined surface in the axial direction of the wiper shaft 2 to increase the connection area of the inner skeleton 31 and the soft connecting portion 32.

[0057] The above-mentioned inner ring body 311 can be a cylindrical structure, which is arranged outside the wiper shaft 2, the sealing lip 321 is formed at one end of the cylindrical structure in the axial direction of the wiper shaft 2, and the cylindrical structure is attached to the side of the first side surface 341 close to the wiper shaft 2,

[0058] Referring to Figures 1 to 4As shown, in some embodiments, the soft connecting portion 32 comprises a second side surface 342 connected with the first side surface 341, and the inner skeleton 31 further comprises a skirt plate 312, one end of the inner ring body 311 is connected with the sealing lip 321, and the skirt plate 312 is formed at the other end of the inner ring body 311 and is curved towards the direction away from the wiper shaft 2 to support at the connection between the first side surface 341 and the second side surface 342. In this way, the skirt plate 312 further increases the contact area of the inner skeleton 31 with the soft connecting portion 32, and improves the supporting effect of the inner skeleton 31 on the soft connecting portion 32.

[0059] Specifically, the second side surface 342 is arranged on the side of the first side surface 341 away from the wiper shaft 2 in the radial direction of the wiper shaft 2, and the first side surface 341 is arranged obliquely relative to the wiper shaft 2 in the axial direction of the wiper shaft 2, and one end of the second side surface 342 is connected to the end of the first side surface 341 in the axial direction of the wiper shaft 2.

[0060] The inner ring body 311 can be a cylindrical structure, which is sleeved outside the wiper shaft 2, the sealing lip 321 is located at one end of the cylindrical structure in the axial direction of the wiper shaft 2, the other end of the cylindrical structure is formed with the skirt plate 312, and the skirt plate 312 is an arc-shaped panel structure. The cylindrical structure is attached to the side of the first side surface 341 close to the wiper shaft 2, the skirt plate 312 extends to the connection between the first side surface 341 and the second side surface 342, and the skirt plate 312 is attached to the connection between the first side surface 341 and the second side surface 342.

[0061] Referring to Figures 1 to 4 As shown, in some embodiments, the soft connecting portion 32 is formed with a mounting ring groove 323, and the outer skeleton 33 is mounted in the mounting ring groove 323. In this way, the mounting ring groove 323 can define the relative position between the outer skeleton 33 and the soft connecting portion 32, and it is convenient to arrange the mounting ring groove 323 at the specified position of the soft connecting portion 32.

[0062] Specifically, the mounting ring groove 323 is recessed on one side surface of the soft connecting portion 32 in the axial direction of the wiper shaft 2, the mounting ring groove 323 is arranged around the inner skeleton 31, and the outer skeleton 33 is arranged in the mounting ring groove 323. The outer skeleton 33 can be connected with the inner wall of the mounting ring groove 323, or the outer skeleton 33 can be an integrated structure with the soft connecting portion 32.

[0063] Referring to Figures 1 to 4 As shown, in some embodiments, the inner skeleton 31, the soft connecting portion 32 and the outer skeleton 33 are a two-color injection integrated structure. In this way, the manufacturing cost of two-color injection is low, and the operation of mutual connection and assembly of the inner skeleton 31, the soft connecting portion 32 and the outer skeleton 33 is avoided.

[0064] Specifically, when two-color injection molding is selected, the inner frame 31 and the outer frame 33 are first injection molded in a mold, and then the soft connecting part 32 is injection molded in the mold, and finally the inner frame 31, the soft connecting part 32 and the outer frame 33 are integrally formed in the mold.

[0065] The inner frame 31 and the outer frame 33 described above can be made of hard rubber material or plastic, and the soft connecting part 32 is made of soft rubber material, wherein the soft rubber material can be selected from thermoplastic vulcanizate (TPV) and thermoplastic elastomer (TPE). The elastic modulus of the inner frame 31 and the outer frame 33 is greater than that of the soft connecting part 32, that is, the soft connecting part 32 is more easily deformed than the inner frame 31 and the outer frame 33. The inner frame 31 and the outer frame 33 can be made of the same material, and of course the inner frame 31 and the outer frame 33 can be made of different materials, as long as the elastic modulus of the inner frame 31 and the outer frame 33 is greater than that of the soft connecting part 32.

[0066] The vehicle cover assembly provided in the application is used in particular, the wiper shaft 2 is arranged in the process hole 11, the sealing ring 3 is sleeved on the wiper shaft 2, the clamping part 332 is clamped and connected with the vent cover 1 at the edge of the process hole 11, and the abutting lip 322 is sealingly abutted with the vent cover 1. The inner frame 31 is sleeved on the outer side of the wiper shaft 2, and the edge of the sealing lip 321 is abutted with the outer circumferential surface of the wiper shaft 2.

[0067] When the wiper shaft 2 is offset in the process hole 11, the wiper shaft 2 will abut against the inner frame 31 to push the inner frame 31 to move, and the sealing lip 321 moves together with the inner frame 31, so that the shape and size of the sealing lip 321 remain stable, to ensure that the sealing lip 321 is always abutted with the outer circumferential surface of the wiper shaft 2.
