TECHNICAL FIELD
[0001] The utility model relates to a kind of brushing devices, especially a kind of simple structure, not space-occupying, durable and wide brushing range brushing device. BACKGROUND
[0002] Vehicle, aircraft, ship and other vehicles are usually provided with brushing device, which can be used to wipe off the dust or water on the windshield to ensure the clear vision of the driver. However, the brushing range of the existing brushing device is generally fan-shaped, which cannot cover the corner part of the windshield, and the brushing area is limited. In addition, the existing brushing device occupies a lot of engine room space for its connecting rod mechanism. Moreover, although some current improvements use horizontal brush pieces to move in the vertical direction or use vertical brush pieces to move in the horizontal direction to make the brushing range cover the corner part of the windshield, such brushing devices usually have tracks, chains or ropes to limit or drive the moving direction of the brush pieces. Such design is prone to failure due to silt accumulation, breakage or wear and tear, and is not a good durable design. Furthermore, some designs avoid tracks, chains or ropes and achieve the effect of expanding the coverage range, but cannot be stored in a position that does not block the line of sight when not in use. Therefore, improvement is necessary. SUMMARY

[0043] As shown in Figures 1-2 The brushing device 1 is used to brush the to-be-brushed article 2, wherein the to-be-brushed article 2 can be a sheet structure made of glass material or other light-transmitting plastic. The brushing device 1 comprises a brush rod 11, a brush piece 12, a linkage rod 13, a first transmission arm 14, a second transmission arm 15, a first linkage arm 16 and a second linkage arm 17. The brush rod 11 comprises a first section 111 and a second section 112 opposite to each other, and an intermediate section 113 connected between the two sections 111, 112. The brush piece 12 is installed on the brush rod 11 and can be driven by the brush rod 11 to brush the to-be-brushed article 2. The linkage rod 13 comprises a first end 131 and a second end 132 opposite to each other, and an intermediate part 133 connected between the two ends 131, 132, and the linkage rod 13 is parallel to the brush rod 11. The first transmission arm 14 comprises a first rotating end 141 and a first transmission end 142 opposite to each other, the first rotating end 141 is rotatably arranged near the lower edge of the to-be-brushed article 2, and the first transmission end 142 is rotatably connected to the first end 131 of the linkage rod 13. The second transmission arm 15 comprises a second rotating end 151 and a second transmission end 152 opposite to each other, the second rotating end 151 is rotatably arranged near the lower edge of the to-be-brushed article 2, and the second transmission end 152 is rotatably connected to the second end 132 of the linkage rod 13. The first linkage arm 16 is arranged between the linkage rod 13 and the brush rod 11 and comprises a first matching end 161 and a first linkage end 162 opposite to each other, the first matching end 161 is rotatably connected to the first end 131 of the linkage rod 13 and directly or indirectly rotatably engaged with the first transmission end 142 of the first transmission arm 14, and the first linkage end 162 is rotatably connected to the first section 111 of the brush rod 11. The second linkage arm 17 is arranged between the linkage rod 13 and the brush rod 11 and comprises a second matching end 171 and a second linkage end 172 opposite to each other, the second matching end 171 is rotatably connected to the second end 132 of the linkage rod 13 and directly or indirectly rotatably engaged with the second transmission end 152 of the second transmission arm 15, and the second linkage end 172 is rotatably connected to the second section 112 of the brush rod 11, wherein the rotation axis line of the first transmission end 142 and the second transmission end 152 is parallel to the rotation axis line of the first matching end 161 and the second matching end 171.
[0044] As shown in Figure 1and Figure 3 As shown, the first drive arm 14 and the second drive arm 15 swing synchronously in parallel with each other, and the first connecting arm 16 and the second connecting arm 17 swing synchronously in parallel with each other. Since the shape of the object to be brushed 2 is symmetrical from left to right, the rotation axis of the first rotating end 141 of the first drive arm 14 and the rotation axis of the second rotating end 151 of the second drive arm 15 are located on both sides of the central longitudinal axis of the object to be brushed 2 and are symmetrical with respect to the aforementioned central longitudinal axis.
[0045] In addition, such as Figures 1-3 As shown, in this embodiment, the object to be brushed 2 is roughly an isosceles trapezoidal structure, narrower at the top and wider at the bottom. To ensure that the brushing range of the brushing device 1 can almost cover the entire object to be brushed 2, the length of the brush rod 11 and the length of the brush 12 can be roughly equal to the upper width (i.e., the width of the narrower side) of the object to be brushed 2. The lengths of the first connecting arm 16 and the second connecting arm 17 are equal, and the lengths of the first transmission arm 14 and the second transmission arm 15 are equal. The lengths of the first connecting arm 16 and the second connecting arm 17 can be greater than the lengths of the first transmission arm 14 and the second transmission arm 15, respectively. The difference can be roughly half the difference between the lower width (i.e., the width of the wider side) and the upper width (i.e., the width of the narrower side) of the object to be brushed 2. The sum of the lengths of the connecting arms and the transmission arms on the same side (e.g., the sum of the lengths of the first connecting arm 16 and the first transmission arm 14) can be roughly equal to the height of the object to be brushed 2. Thus, when the brushing device 1 is shaped like this... Figure 3 In the first retracted state S1 shown, the brush rod 11 and brush 12 are close to the lower part of the object to be brushed 2 and biased towards one side (e.g., the right side) of the object to be brushed. When the brushing device 1 is in the like... Figure 3 In the second retracted state S2 shown, the brush rod 11 and brush 12 are close to the lower part of the object to be brushed 2 and biased towards the other side (e.g., the left side) of the object to be brushed 2. When the brushing device 1 switches from the first retracted state S1 or the second retracted state S2 to the extended state S0, the brush rod 11 and brush 12 are close to the upper center of the object to be brushed 2, and the first transmission arm 14 and the first connecting arm 16 are arranged in the same straight line, and the second transmission arm 15 and the second connecting arm 17 are also arranged in the same straight line. That is, when the brushing device 1 is in the extended state S0, the distance between the first transmission arm 14 and the second transmission arm 15 is equal to the distance between the first connecting arm 16 and the second connecting arm 17.
[0046] Understandably, the aforementioned brushing device can also be used to brush objects that are not isosceles trapezoids. For example, if the object to be brushed is a parallelogram, the brushing device can be configured as follows: Figure 3 The first folded state S1 shown can be moved to the unfolded state S0 and then back to the first folded state S1, or it can be done as follows: Figure 3 The second folded state S2 shown is moved to the unfolded state S0 and then back to the second folded state S2, so that the brushing area can be maximized and roughly cover the entire object to be brushed.
[0047] As Figure 1 With Figure 4 shown, the brushing device 1 further comprises a first power source 18 coupled to the first rotating end 141 of the first transmission arm 14, which can be used to drive the first transmission arm 14 to swing back and forth, so as to enable the brush rod 11 to drive the brush 12 to brush the object 2 to be brushed. It is worth noting that during the swinging of the first transmission arm 14 back and forth, the second transmission arm 15 can swing synchronously with the first transmission arm 14 under the action of the connecting rod 13. Preferably, the brushing device 1 further comprises a second power source 19 coupled to the second rotating end 151 of the second transmission arm 15, which can be used as a backup power source to drive the second transmission arm 15 to swing back and forth when the first power source 18 fails, and the first transmission arm 14 can swing synchronously with the second transmission arm 15 under the action of the connecting rod 13, so as to ensure that the brush 12 can still normally brush the object 2 to be brushed, thereby improving the use reliability. However, the utility model is not limited to this embodiment, for example, in another embodiment, the brushing device can only comprise a single power source coupled to the first rotating end of the first transmission arm or coupled to the second rotating end of the second transmission arm.
[0048] Specifically, as Figure 4 shown, the first power source 18 comprises a first driving member 181 and a motor 182 used to drive the first driving member 181, and the first driving member 181 comprises a plurality of first driving teeth. The first rotating end 141 of the first transmission arm 14 is provided with a first matching driving member 143, and the first matching driving member 143 comprises a plurality of first matching driving teeth used to cooperate with the first driving teeth.
[0049] In this embodiment, the structure and action relationship of the second power source 19 and the second transmission arm 15 are the same as those of the first power source 18 and the first transmission arm 14, and for the sake of brevity, they will not be described here.
[0050] In addition, as Figure 5As shown, the first transmission arm 14 is provided with a first transmission member 144 on the first transmission end 142, which comprises a plurality of first transmission teeth. The first linkage arm 16 is provided with a first matching member 163 on the first matching end 161, which comprises a plurality of first matching teeth for matching with the first transmission teeth. Preferably, the wiping device 1 further comprises a first casing member 145 for covering and isolating the first transmission member 144 and the first matching member 163 from foreign matters (dust or water), wherein the first casing member 145 can comprise two half casing members 1451 capable of being separated from each other for facilitating maintenance or replacement operation. More specifically, the first transmission member 144 and the first matching member 163 can be circular structures, such as circular gears, and the plurality of first transmission teeth of the first transmission member 144 and the plurality of first matching teeth of the first matching member 163 are rotationally engaged with each other. Since the relative positions of the first transmission member 144 and the first matching member 163 can be fixed under the limiting action of the linkage rod 13, the first transmission arm 14 can drive the first linkage arm 16 to swing back and forth in the opposite direction when swinging back and forth. However, the present application is not limited to this embodiment. Understandably, in another embodiment, the first transmission member and the first matching member can be half circular gears to leave space for storing lubricating grease in the corresponding casing.
[0051] As shown, Figure 6 In this embodiment, the structure and action relationship of the second transmission arm 15 and the second linkage arm 17 are the same as those of the first transmission arm 14 and the first linkage arm 16, and thus will not be described herein for the sake of brevity.
[0052] Further, as shown, Figure 2 and Figure 7 The first linkage arm 16 comprises a first connecting section 164, a first joint 165 and a first movable section 166. The first connecting section 164 is adjacent to the linkage rod 13 and comprises the first matching end 161, the first movable section 166 is adjacent to the brush rod 11 and comprises the first linkage end 162, and the first joint 165 is arranged between the first movable section 166 and the first connecting section 164 to allow the first movable section 166 to move relative to the first connecting section 164, thereby allowing the brush rod 11 to drive the brush member 12 to attach to or move away from the object to be wiped 2. Preferably, the first joint 165 is arranged with a first elastic member 167, which allows the brush rod 11 to have potential energy to drive the brush member 12 to attach to the object to be wiped 2, that is, the first elastic member 167 constantly elastically drives the brush member 12 to attach to the object to be wiped 2.
[0053] In this embodiment, the structure and action relationship of the second linkage arm 17, the linkage rod 13 and the brush rod 11 are the same as those of the first linkage arm 16, the linkage rod 13 and the brush rod 11, and thus will not be described herein for the sake of brevity.
[0054] Further, for the convenience of replacement of the brush member 12, as shown, Figure 2, Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, the brushing device 1 further includes a controller 10 (e.g., a control circuit board) electrically connected to the first power source 18 and / or the second power source 19. The controller 10 is used to receive signals to control the first power source 18 and / or the second power source 19 to keep the brushing device 1 in the extended state S0, so that the user can operate the first movable section 166 of the first linkage arm 16, the second movable section of the second linkage arm 17 and / or the brush rod 11 to move the brush rod 11 and the brush 12 away from the object to be brushed 2. In addition, the controller 10 can also be used to control the rotation start and stop, direction and / or speed change of the first power source 18 and / or the second power source 19.
[0055] like Figure 9 As shown, unlike the first embodiment, in the second embodiment, the plurality of first transmission teeth of the first transmission member 144' of the first transmission arm and the plurality of first mating teeth of the first mating member 163' of the first connecting arm do not directly rotate and mesh with each other, and the plurality of second transmission teeth of the second transmission member 154' of the second transmission arm and the plurality of second mating teeth of the second mating member 173' of the second connecting arm do not directly rotate and mesh with each other. Specifically, the brushing device 1' in this embodiment further includes a first transmission engagement member 101' and a second transmission engagement member 102'. Multiple meshing teeth of the first transmission engagement member 101' rotatably mesh with multiple first transmission teeth of the first transmission member 144' and multiple first mating teeth of the first mating member 163'. Multiple meshing teeth of the second transmission engagement member 102' rotatably mesh with multiple second transmission teeth of the second transmission member 154' and multiple second mating teeth of the second mating member 173'. Furthermore, the rotation axis connecting the first transmission end 142' and the second transmission end 152' coincides with the rotation axis connecting the first mating end 161' and the second mating end 171'. It is worth noting that the number and structure of the first and second transmission engagement members are not limited to those shown in the drawings of this embodiment; their configuration depends on actual design requirements.
[0056] like Figure 10 , Figure 11As shown, unlike the first embodiment, the motor 182" of the first power source 18" and the motor 192" of the second power source 19" in the third embodiment are disposed within the linkage rod 13", the first driving member 181" of the first power source 18" is located between the first transmission member 144" and the first mating member 163", the second driving member 191" of the second power source 19" is located between the second transmission member 154" and the second mating member 173", the first transmission teeth of the first transmission member 144" and the first mating teeth of the first mating member 163" are engaged with the first driving teeth of the first driving member 181", and the second transmission teeth of the second transmission member 154" and the second mating teeth of the second mating member 173" are engaged with the first driving teeth of the second driving member 191". Understandably, one of the first power source 18" and the second power source 19" can be selectively omitted.
