Description

TECHNICAL FIELD

[0001] The present application relates to a surface cleaning device, in particular to a wiper with an adjusting function. BACKGROUND

[0002] Traditional wipers can be generally divided into two categories: bone wipers and boneless wipers. The bone wipers can be further divided into segmented bone wipers and traditional bone wipers. The boneless wipers can be further divided into one-piece double-steel-piece boneless wipers, one-piece single-steel-piece boneless wipers, segmented boneless wipers and composite boneless wipers.

[0003] The bone wiper transmits pressure to the wiper rubber strip through the fulcrum of the hard steel frame. The pressure at the contact part of the fulcrum and the rubber strip is much greater than that at other parts of the rubber strip, which easily causes the contact part to age and deform, and finally causes strip-shaped water stains to remain during operation. The force at the force point is equal, but the force point is relatively small, and the force distribution of the rubber strip is uneven, which inevitably leads to poor adhesion of the rubber strip to the glass, and causes the wiper rubber strip to easily leak and the windshield to be not clean. To solve the above problems of the bone wiper, the general mechanical solution is to increase the wiper arm pressure to force the rubber strip to adhere to the glass and reduce the leakage, but this has the advantages of tight adhesion and relatively clean windshield, and the disadvantage of large scraping noise.

[0004] The boneless wiper transmits pressure to the wiper rubber strip through the built-in memory elastic steel sheet structure to disperse the pressure points and evenly distribute the force of the rubber strip. The force point is large, and the force distribution of the rubber strip is relatively uniform, but the force at the force point is different, with the largest force at the center of the steel sheet and gradually decreasing towards the two ends of the wiper, which inevitably leads to different friction forces at the contact points between the rubber strip and the glass, causing the wiper rubber strip to be out of sync and easily produce abnormal noise. To solve the above problems of the boneless wiper, the general mechanical solution is to reduce the elasticity of the elastic steel sheet to reduce the pressure at the middle of the rubber strip and gradually decrease towards the two ends, but this has the advantages of small noise, but the disadvantages of leakage at the two ends of the wiper and unclean windshield; or the application of the wiper is limited by the length of the wiper.

[0005] Therefore, whether it is a bone wiper or a boneless wiper, they will inevitably have defects in their respective windshield wiping effects due to the shortcomings of their own structures. SUMMARY

[0031] ​​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0032] With reference to Figures 1 to 3 As shown in the drawings, the embodiments of the present application disclose a wiper, which comprises a support part, a rubber strip 100 and an adjusting mechanism. The wiper in the present embodiment is a boneless wiper. In the present embodiment, the support part comprises a main steel sheet 13 made of elastic steel sheet material. The main steel sheet 13 has a length direction, a width direction and a thickness direction perpendicular to each other. The main steel sheet 13 has opposite first and second side surfaces in the thickness direction. The first side surface of the main steel sheet 13 is used to be connected with a car through an end head 10. When the main steel sheet 13 is not pressed, the main steel sheet 13 is in an arch shape, i.e. the cross-sectional shape of the plane formed by the length and thickness directions of the main steel sheet 13 is arc-shaped. When the main steel sheet 13 is installed on a car, the main steel sheet 13 is deformed to a certain extent after being pressed by the end head 10 or other components on the first side surface, so that the rubber strip 100 is tightly pressed against the car glass. At this time, the cross-sectional shape of the plane formed by the length and width directions of the main steel sheet 13 is strip-shaped. Figure 1 As shown in the drawings, and the main steel sheet 13 can be rotated relative to the car glass under the drive of the end head 10. The first side surface of the main steel sheet 13 is further provided with a bracket 11 for connecting with the end head 10, and two flow guide strips 12 arranged on both sides of the bracket 11, wherein the main steel sheet 13 is arranged in the two flow guide strips 12. The two ends of the main steel sheet 13 in the length direction are further provided with two limiting parts 15, which respectively connect the flow guide strips 12, the main steel sheet 13 and the rubber strip 100.

[0033] With reference to Figure 2 As shown in the drawings, in the present embodiment, the adjusting mechanism comprises a plurality of claws 14 arranged at intervals along the length direction of the main steel sheet 13. Each claw 14 is arranged on the second side surface of the main steel sheet 13. In the present embodiment, the main steel sheet 13 is provided with a plurality of positioning holes arranged at intervals along the length direction thereof. Each claw 14 is fixed to the main steel sheet 13 through the positioning hole by means of a fastener such as a bolt or a screw. Each claw 14 is formed with a hook portion on the side away from the main steel sheet 13. The rubber strip 100 passes through the hook portion of each claw 14, so as to be limited by each claw 14.

[0034] In the embodiment, each of the claws 14 is made of elastic material. Preferably, each of the claws 14 can also be made of elastic steel sheet. Of course, in other alternative embodiments, each of the claws 14 can also be made of other elastic material with certain strength and elasticity as required. When the main steel sheet 13 is not pressed, each of the claws 14 is in arch shape, i.e. the cross section of the plane formed by the length and thickness of each of the claws 14 is in certain arc shape. When the main steel sheet 13 is installed on the car, the claws 14 are pressed and deformed to be linear along the length direction of the main steel sheet 13.

[0035] In the prior art, the claws 14 are only used to limit the position of the rubber strip 100 and do not have elasticity. The force transmission sequence of the prior art boneless wiper is: the end head 10 arranged on the car → the support 11 → the main steel sheet 13 → the rubber strip 100. At this time, the pressure F (rubber strip 100) on each point of the rubber strip 100 is equal to the pressure F (pressure) on each point of the main steel sheet 13 in the length direction. That is, F (rubber strip 100) = F (pressure). Since the prior art boneless wiper has inherent mechanical characteristics, i.e. the center of the main steel sheet 13 is subjected to the maximum force, and the force on the main steel sheet 13 gradually decreases from the center to both ends in the length direction. Therefore, the forces on each point of the rubber strip 100 of the prior art boneless wiper along the length direction are different.

[0036] On the contrary, in the embodiment, since the claws 14 have certain elasticity, when the claws 14 are subjected to force, the claws 14 will be deformed along the length direction of the main steel sheet 13, and at this time, the force transmission sequence of the wiper is: the end head 10 arranged on the car → the support 11 → the main steel sheet 13 The claws 14 The rubber strip 100. The claws 14 will adjust the force on the rubber strip 100 along the length direction of the main steel sheet 13 with the deformation of the claws 14, so that the force on the rubber strip 100 along the length direction tends to be consistent. The elastic adjusting device produces deformation to adjust the pressure change caused by the change of the distance between the to-be-cleaned surface and the swing arm, to prevent excessive pressure from causing excessive pressing and deformation of the rubber strip.

[0037] In the prior art, when the interface of the car glass changes, for example, there is impurity or foreign matter on the glass, the friction force on the rubber strip 100 and the glass corresponding to the position will suddenly increase, which in turn will cause deformation or damage of the rubber strip 100 and other adverse effects.

[0038] On the contrary, in the embodiment, when the interface of the car glass changes, for example, there is impurity or foreign matter on the glass, the claws 14 of the wiper can automatically deform according to the impurity or foreign matter, realize flexible structure adjustment of the wiper, and make the friction force between the rubber strip 100 and the glass almost balanced. Thus, the wiper corresponds to the dynamic change of the interface with the glass.

[0039] Referring to Figure 3 In one preferred embodiment, as shown in the figure, the strip 100 is provided with a groove 19 extending along the length of the strip 100, and the hook 18 is inserted into the groove 19 of the strip 100, and the hook 18 can slide in the groove 19 of the strip 100 when the claw 14 is deformed. In other words, the claw 14 can limit the strip 100 through the hook 18 and the groove 19, but the groove 19 of the strip 100 does not limit the deformation of the claw 14 along the length of the main blade 13.

[0040] In particular, the claw 14 is limited by the main blade 13, the fastener and the strip 100 in the thickness direction of the main blade 13. That is, although the claw 14 is elastic, the claw 14 cannot or substantially cannot be deformed in the thickness direction of the main blade 13. The claw 14 is limited by the strip 100 in the width direction of the main blade 13. That is, although the claw 14 is elastic, the claw 14 cannot or substantially cannot be deformed in the width direction of the main blade 13. Thus, when the claw 14 is subjected to a force, it can only be deformed in the length direction of the main blade 13, and this deformation is what we need to adjust the deformation of the force on each point of the strip 100 in the length direction.

[0041] In one preferred embodiment, in order to adapt to the force on the main blade 13 gradually decreasing from the center to both ends of the length direction, the elasticity of each claw 14 also gradually increases from the center of the main blade 13 to both ends of the length direction of the main blade 13, thereby ensuring that the pressure on each force point on the strip 100 is close to the same, the friction on each force point on the strip 100 is also close to the same, the swing of the strip 100 is synchronized, the wiping is smoother, and the wiping noise is reduced, and the wiping is quieter.

[0042] In this embodiment, each claw 14 can be made of the same material of elastic steel sheet. However, the thickness of each claw 14 gradually decreases from the center of the main blade 13 to both ends of the length direction of the main blade 13.

[0043] In an optional embodiment, each of the claws 14 is made of the same material, and the length of each of the claws 14 increases from the center of the main steel sheet 13 to the two ends of the main steel sheet 13 in the length direction. For example, in an optional embodiment, the claws 14 can be four, and from left to right, they are the first claw, the second claw, the third claw, and the fourth claw. Among them, the first claw and the second claw are located on the left side of the bracket 11, and the second claw is located between the first claw and the connecting seat. Therefore, the elasticity of the second claw is greater than that of the first claw. The thickness of the second claw is greater than that of the first claw. Among them, the third claw and the fourth claw are located on the right side of the bracket 11, and the third claw is located between the fourth claw and the connecting seat. Therefore, the elasticity of the third claw is greater than that of the fourth claw. The thickness of the third claw is greater than that of the fourth claw. Considering force balance, the second claw can be symmetrically arranged relative to the third claw; the first claw and the fourth claw are symmetrically arranged.

[0044] In a preferred embodiment, the embedded holding pressure strip embedded in the rubber strip 100 can adopt a pre-bent memory elastic steel sheet. Because the force point of the holding pressure strip of the pre-bent memory elastic steel sheet on the claw 14 will again uniformly distribute the force, the force point will increase, and the wiper rubber strip 100 will better adhere to the glass

[0045] In summary, the present embodiment has the following advantages:

[0046] 1. Since the force on each point of the rubber strip 100 is self-balanced, the rubber strip 100 on both sides can be more tightly attached to the glass than before, thereby optimizing the adhesion of the wiper rubber strip 100 to the glass, thereby striving to ensure that the rubber strip 100 remains adhered to the glass from beginning to end to improve the wiper's rain wiping and cleaning ability.

[0047] 2. Further optimize and adjust the pressure size and pressure contact point distribution between the wiper blade rubber strip 100 and the glass interface, so that the pressure points between the boneless wiper rubber strip 100 and the glass are almost the same, the friction between the rubber strip 100 and the glass is almost balanced, and the rain is more smooth and quiet.

[0048] 3. After using the present embodiment, since the pressure difference of each point of the rubber strip 100 is reduced, the adjustment range of the main pressure can be expanded, thereby enabling the size of the boneless wiper to be lengthened, so that the size of the boneless wiper can be adapted to other application fields such as passenger cars and commercial vehicles.

[0049] Reference Figure 4 and Figure 5As shown, the embodiment of the present application discloses a wiper, which comprises a supporting part, a rubber strip 100 and an adjusting mechanism. The wiper in the embodiment is a wiper with a frame. The supporting part comprises a main frame 23 connected with a main arm and a vehicle and a plurality of sub-frames 24 arranged on the main frame 23 and arranged along the length direction of the main frame 23. The main frame 23 and the sub-frames 24 are made of rigid materials. The rubber strip 100 can be embedded with an embedded supporting strip for preventing bending deformation.

[0050] The adjusting mechanism comprises a plurality of clamping claws 14 arranged on each sub-frame 24 and located on the side away from the main frame 23. The plurality of clamping claws 14 are arranged along the length direction of the main frame 23. Each clamping claw 14 is formed with a hook portion on the side away from the main steel sheet 13. The rubber strip 100 passes through the hook portion of each clamping claw 14 and is limited by each clamping claw 14.

[0051] In the embodiment, each clamping claw 14 is made of an elastic material. Preferably, each clamping claw 14 can also be made of an elastic steel sheet. Of course, in other optional embodiments, each clamping claw 14 can also be made of other elastic materials with certain strength and elasticity according to needs. When the wiper is not pressed, each clamping claw 14 is in an arc shape, i.e., the cross-sectional shape of the plane formed by the length and thickness of each clamping claw 14 is in an arc shape. When the wiper is installed on the vehicle, the clamping claw 14 is pressed and deformed to be linear along the length direction of the main frame 23.

[0052] In the prior art, the clamping claw 14 is only used for limiting the rubber strip 100 and does not have elasticity. The wiper with a frame uniformly applies pressure to several stress points through several fixed points in stages, and the force transmission sequence is: main arm→main frame 23→sub-frame 24→clamping claw 14 Embedded supporting strip Rubber strip 100. At this time, the pressure F(rubber strip 100) borne by each point of the rubber strip 100 is equal to the pressure F(Compression) borne by each point of the main steel sheet 13 in the length direction. That is, F(rubber strip 100)=F(Compression). Although the force of the stress points of the wiper with a frame is equal, the number of stress points is relatively small, and the force distribution of the rubber strip 100 is uneven, which will inevitably lead to poor adhesion of the rubber strip 100 to the glass, and the wiper rubber strip 100 is prone to missing wiping, and the wiping is not clean.

[0053] Since the clamping claw 14 has a certain elasticity, when the clamping claw 14 is subjected to an acting force, the clamping claw 14 will deform along the length direction of the main steel sheet 13. At this time, the force transmission sequence of the wiper is: main arm→main frame 23→sub-frame 24→clamping claw 14 Embedded supporting strip The clamping jaw 14 can adjust the force acting on the rubber strip 100 along the length direction of the main steel sheet 13 by deforming itself, so that the force acting on the rubber strip 100 along the length direction tends to be consistent. The elastic adjusting device deforms to adjust the pressure change caused by the change of the distance between the surface to be cleaned and the swing arm, so as to prevent the pressure from being too large to cause excessive extrusion and deformation of the rubber strip 100. In this way, the pressure on each force point of the rubber strip 100 is close to the same, and the friction on each force point of the rubber strip 100 is also close to the same. In addition, due to the elastic structure of the clamping jaw 14, the contact points between the rubber strip 100 and the glass are increased. In this way, the wiper rubber strip 100 swings synchronously, and the wiper rubber strip 100 is more closely attached to the glass, so that the wiper is smoother, the noise is reduced, and the wiper is quieter. In addition, due to the elastic structure of the clamping jaw 14, the contact points between the rubber strip 100 and the glass are increased, and the wiper is more closely attached to the glass, so that the wiper is cleaner.

[0054] In a preferred embodiment, the embedded holding pressure strip can adopt a pre-bent memory elastic steel sheet. Due to the uniform force distribution of the pre-bent memory elastic steel sheet holding pressure strip to the force points of the clamping jaw 14, the force points are increased, and the wiper rubber strip 100 is better attached to the glass.

[0055] In particular, since the clamping jaw 14 is limited in the thickness direction of the auxiliary frame 24 by the auxiliary frame 24, the fastener and the rubber strip 100. That is, although the clamping jaw 14 has elasticity, the clamping jaw 14 cannot or basically cannot deform in the thickness direction of the auxiliary frame 24. The clamping jaw 14 is limited in the width direction of the auxiliary frame 24 by the rubber strip 100. That is, although the clamping jaw 14 has elasticity, the clamping jaw 14 cannot or basically cannot deform in the width direction of the auxiliary frame 24. Therefore, when the clamping jaw 14 is subjected to a force, it can only deform in the length direction of the auxiliary frame 24, and this deformation is the deformation we need to adjust the force acting on the rubber strip 100 along the length direction.

[0056] In the prior art, when the interface of the automobile glass changes, for example, there is impurity or foreign matter on the glass, the friction between the rubber strip 100 and the glass corresponding to the position will suddenly increase, and then the rubber strip 100 will be deformed or damaged, etc.

[0057] On the contrary, in the present embodiment, when the interface of the automobile glass changes, for example, there is impurity or foreign matter on the glass, the clamping jaw 14 of the wiper can automatically deform according to the impurity or foreign matter, realize the flexible structure adjustment of the wiper, and make the friction between the rubber strip 100 and the glass almost balanced. Therefore, the wiper corresponds to the dynamic change of the contact interface with the glass.

[0058] In a preferred embodiment, the adhesive strip 100 is provided with a groove 19 extending along the length of the adhesive strip 100, and the hook 18 is inserted into the groove 19 of the adhesive strip 100, and the hook 18 can slide in the groove 19 of the adhesive strip 100 when the clamping jaw 14 is deformed. In other words, the clamping jaw 14 can limit the adhesive strip 100 through the hook 18 and the groove 19, but the groove 19 of the adhesive strip 100 does not limit the deformation of the clamping jaw 14 along the length of the main steel sheet 13.

[0059] In a preferred embodiment, in order to adapt to the fact that the force at each stress point of the boneless wiper is equal, the elasticity of each clamping jaw 14 is also equal, thereby ensuring that the pressure on each stress point of the adhesive strip 100 is close to being equal, the friction on each stress point of the adhesive strip 100 is close to being equal, the swinging of the adhesive strip 100 is synchronized, the wiper is smoother, and the wiper is quieter.

[0060] In summary, the present embodiment has the following advantages:

[0061] 1. Since the forces at each point of the adhesive strip 100 are self-balanced and the number of stress points is increased, the two sides of the adhesive strip 100 can be more closely attached to the glass than before, thereby optimizing the adhesion of the wiper adhesive strip 100 to the glass, thereby striving to ensure that the adhesive strip 100 remains attached to the glass at all times, thereby improving the wiper's ability to wipe and clean.

[0062] 2. Further optimizing the distribution of pressure size and pressure contact points between the wiper adhesive strip 100 and the glass interface, so that the pressure points between the boneless wiper adhesive strip 100 and the glass are almost the same, the friction between the adhesive strip 100 and the glass is almost balanced, the wiper is smoother and quieter.

[0063] 3. After using the present embodiment, since the pressure difference at each point of the adhesive strip 100 is reduced, the adjustment range of the main pressure can be expanded, thereby enabling the bone wiper to meet higher requirements, enabling the bone wiper to better approach the high performance requirements of vehicles such as engineering vehicles, high-speed trains, and aircraft, thereby expanding the application range of the bone wiper.

[0064] Of course, in other alternative embodiments, the wiper can select various types of bone wipers or boneless wipers according to actual conditions.

[0065] For example, the composite boneless wiper in the present embodiment includes a rod member extending along the length thereof and at least two elastic strips. The plurality of elastic strips are arranged on one side of the rod member. Each of the elastic strips is spaced apart along the length of the rod member. Each of the elastic strips can be made of an elastic steel sheet.

[0066] Each elastic strip can be provided with a plurality of elastic claws 14 on the side away from the rod. The specific structure and shape of the claws 14 can refer to the above embodiments, which will not be repeated here.

[0067] For example, the rain wiper with the bone structure in the embodiments of the present application can also be other corresponding structures. For example, the rain wiper includes a main skeleton 23 and a secondary skeleton 24 (non-segmented type). The secondary skeleton 24 is provided with a plurality of elastic claws 14. Each elastic strip can be provided with a plurality of elastic claws 14 on the side away from the rod. The specific structure and shape of the claws 14 can refer to the above embodiments, which will not be repeated here.

[0068] The principles and implementation manners of the present application are described by using specific embodiments. The above embodiment descriptions are only used to help understand the method and core idea of the present application. Meanwhile, for those skilled in the art, the specific implementation manners and application ranges will be changed according to the idea of the present application. In summary, the content of the specification should not be understood as a limitation of the present application.
