[0112] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0113] According to the first aspect of the present application, referring to Figure 1 and Figure 2 The present application provides a wiper arm 10 , including a swing arm 110 , a spray component 120 and a cover component 130 .

[0114] See also Fig.12 and Fig.13The swing arm 110 has a spray channel, the spray member 120 has at least one medium spray port 120 a and a medium input port 120 b connected to the spray channel, and the cover member 130 has at least one accommodating space 13 e for accommodating the spray member 120 .

[0115] See also Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The swing arm 110 includes a hook plate 112, a scraper rod 113, a scraper arm rod 114 and a rod head 115 which are connected in sequence. A swing arm interface 111 is formed on the hook plate 112. The rod head 115 is rotationally connected to the motor on the wiper assembly. The hook plate 112 is connected to the scraper rod 113. The scraper arm rod 114 is connected to the scraper rod 113. The scraper arm rod 114 is provided with an insertion space 11f. At least a portion of the scraper rod 113 is located in the insertion space 11f. The rod head 115 is rotationally connected to the scraper arm rod 114.

[0116] Through the structural setting of the swing arm 110, the swing arm 110 is more stable when in use.

[0117] See also Figure 2 The wiper arm 10 further includes a water pipe 20, at least part of which is connected to a cleaning medium source, see Fig.12 At least part of the water pipe 20 is connected to the medium input port 120b of the spray element 120, and the cleaning medium at the cleaning medium source enters the spray channel, and then flows from the medium input port 120b to the medium spray port 120a along the water spray channel, and then is sprayed from the medium spray port 120a to the surface to be cleaned, thereby completing the effect of cleaning the surface to be cleaned on the vehicle.

[0118] In order to install the water pipe 20 on the swing arm 110, the sections of the water pipe 20 can be fixed to the hook plate, the scraper rod 113, the scraper arm rod 114 and the rod head 115 by fasteners, and the structure of the fasteners can be U-shaped clamps.

[0119] See also Figures 10 to 12 The spraying element 120 includes at least one nozzle structure 123 , and a medium spraying outlet 120 a is formed on the nozzle structure 123 .

[0120] The nozzle structure 123 includes a nozzle body 1231 , and a hole is formed in the nozzle body 1231 , and the hole is equivalent to the medium ejection port 120 a .

[0121] As another optional solution, a hollow cavity can also be formed on the body of the hook plate, scraper rod 113, scraper arm rod 114 and rod head 115. After the hook plate, scraper rod 113, scraper arm rod 114 and rod head 115 are connected, the hollow cavities are connected in sequence to form a spray channel.

[0122] In order to realize the connection between the swing arm 110, the spray part 120 and the cover part 130, see Figure 6 , Figure 7 , Figures 10 to 20 The swing arm 110 has a swing arm interface 111 , the cover member 130 has a cover interface 131 different from the swing arm interface 111 , and the spray member 120 has a mounting interface 121 and a shell connection port 122 .

[0123] The hook plate 112 is connected to the spraying part 120 and the cover part 130 , and the swing arm interface 111 is arranged on the hook plate 112 .

[0124] Among them, the swing arm interface 111 cooperates with the installation interface 121 to realize the connection between the swing arm 110 and the spray part 120, and the cover interface 131 cooperates with the shell connecting port 122 to realize the connection between the cover part 130 and the spray part 120, thereby realizing the connection between the spray part 120, the swing arm 110 and the cover part 130. At the same time, at least part of the spray part 120 is arranged between the swing arm 110 and the cover part 130, so that the spray part 120 and the cover part 130 can form a detachable part relative to the swing arm 110.

[0125] After the spraying member 120 and the covering member 130 are connected, they can form a detachable part relative to the hook plate member 112 .

[0126] By means of the technical solution, at least part of the spray component 120 is arranged between the swing arm 110 and the cover component 130, so that the spray component 120 and the cover component 130 form a detachable whole relative to the swing arm 110. During the assembly process, the operator can first connect the shell connection port 122 of the spray component 120 with the cover interface 131 of the cover component 130 to form a whole, and then use the installation interface 121 of the spray component 120 to connect the whole to the swing arm interface 111 of the swing arm 110, so as to complete the installation of the three. Alternatively, first connect the installation interface 121 on the spray component 120 with the swing arm interface 111 on the swing arm 110, and then connect the cover interface 131 on the cover component 130 with the shell connection port 122 on the spray component 120 to complete the installation of the three. In this way, the operator does not need to distinguish the connection sequence of the spray component 120, the swing arm 110 and the cover component 130, and can quickly complete the installation of the three. There is no need to distinguish the connection sequence of the spray component 120, the swing arm 110 and the cover component 130, which effectively improves the assembly efficiency.

[0127] The spraying member 120 and the cover member 130 form a detachable whole relative to the hook plate member 112. During installation, the whole can be installed on the hook plate member 112, or the whole can be directly removed from the hook plate member 112, which is convenient for assembly and disassembly.

[0128] In some embodiments, see Figure 6 and Figure 7 The swing arm interface 111 includes: a first swing arm interface portion 111a and a second swing arm interface portion 111b.

[0129] The first swing arm interface portion 111a is arranged at the first swing arm position of the swing arm 110, so that when the swing arm interface 111 is combined with the installation interface 121, the relative position of the swing arm 110 and the spray part 120 can be limited; the second swing arm interface portion 111b is arranged at the second swing arm position of the swing arm 110, so that when the swing arm interface 111 is combined with the installation interface 121, the relative position of the swing arm 110 and the spray part 120 can be locked.

[0130] When the first swing arm interface portion 111a limits the relative position of the swing arm 110 and the spray part 120, the swing arm 110 can rotate relative to the spray part 120. When the spray part 120 rotates to the position of the second swing arm interface portion 111b, the second swing arm interface portion 111b can lock the relative position of the swing arm 110 and the spray part 120, thereby achieving the fixation of both the swing arm 110 and the spray part 120.

[0131] The swing arm interface 111 is arranged on the hook plate 112. It can be understood that the first swing arm position is equivalent to the position on the hook plate 112 away from the connection between the hook plate 112 and the scraper rod 113, and the second swing arm position is equivalent to the position on the hook plate 112 close to the connection between the hook plate 112 and the scraper rod 113.

[0132] Therefore, the first swing arm interface portion 111a is equivalent to a position on the hook plate 112 away from the connection between the hook plate 112 and the scraper rod 113, and the second swing arm position is equivalent to a position on the hook plate 112 close to the connection between the hook plate 112 and the scraper rod 113. The spray part 120 can rotate around the first swing arm position on the hook plate 112, and part of it can rotate to the second swing arm position so that the swing arm interface 111 is combined with the mounting interface 121.

[0133] In some embodiments, see Figures 10 to 12 The mounting interface 121 includes: a first mounting interface portion 121a and a second mounting interface portion 121b.

[0134] The first mounting interface portion 121a is arranged at the first mounting position of the spray part 120, so that when the swing arm interface 111 is combined with the mounting interface 121, the first mounting interface portion 121a and the first swing arm interface portion 111a form a movable connection; the second mounting interface portion 121b is arranged at the second mounting position of the spray part 120, so that when the swing arm interface 111 is combined with the mounting interface 121, the second mounting interface portion 121b and the first swing arm interface portion 111a form a fixed connection.

[0135] The first installation position is equivalent to a position on the spray member 120 where the spray member 120 and the hook plate member 112 are restrictedly connected, and the second installation position is equivalent to a position on the spray member 120 where the spray member 120 and the hook plate member 112 are locked and connected.

[0136] The first installation position and the second installation position may be arranged at two opposite ends of the spray element 120 .

[0137] As an optional solution, a third installation interface portion 121c can be set in the middle position of the spray part 120, and a third swing arm interface portion 111c can be set at the third swing arm position of the hook plate part 112. When the swing arm interface 111 is combined with the installation interface 121, the third installation interface portion 121c and the third swing arm interface portion 111c form a fixed connection.

[0138] In some embodiments, see Figures 15 to 17 The first swing arm interface portion 111 a is equivalent to the positioning structure 160 of the swing arm interface 111 , and the first installation interface portion 121 a is equivalent to the embedding structure 170 included in the spray piece 120 .

[0139] The positioning structure 160 has a positioning groove 161. When the embedded structure 170 is embedded in the positioning groove 161, it has at least a movable state and a limited state relative to the positioning structure 160. In the movable state, the embedded structure 170 can rotate relative to the positioning structure 160 so that the spray part 120 rotates relative to the swing arm 110. In the limited state, the embedded structure 170 is stationary relative to the positioning structure 160 so that the spray part 120 and the swing arm 110 remain stationary.

[0140] The spray component 120 rotates relative to the swing arm 110 after being acted upon by the first force. The embedding structure 170 on the spray component 120 can be embedded in the positioning groove 161 of the positioning structure 160 on the swing arm 110. At the same time, the embedding structure 170 can rotate relative to the positioning structure 160, so that the spray component 120 rotates relative to the swing arm 110, thereby finally realizing the assembly of the spray component 120 and the swing arm 110.

[0141] The embedding structure 170 includes a movable contact surface 171 and a limiting contact surface 172 .

[0142] See also Fig.17 The movable contact surface 171 is arranged at the first edge of the embedded structure 170, so that when the embedded structure 170 is in a movable state, the movable contact surface 171 contacts the groove wall of the positioning groove 161; the limiting contact surface 172 is arranged at the second edge of the embedded structure 170, so that when the embedded structure 170 is in a limited state, the limiting contact surface 172 contacts the groove wall of the positioning groove 161.

[0143] The first edge of the embedded structure 170 is connected to the second edge, which can be understood as the first edge and the second edge are inclined and intersecting.

[0144] See also Fig.17 The embedded structure 170 can be set as a block structure, the movable contact surface 171 and the limiting contact surface 172 are respectively surfaces of the block structure, and the movable contact surface 171 is set as an inclined surface, and the limiting contact surface 172 is set as a plane.

[0145] In an example, the movable contact surface 171 may also be configured as an arc surface.

[0146] At least one of the second swing arm interface portion 111b and the third swing arm interface portion 111c includes a hook structure 140, and at least one of the second installation interface portion 121b and the third installation interface portion 121c is equivalent to the slot structure 150 included in the spray part 120. The hook structure 140 is located in the slot structure 150, thereby locking the relative position of the swing arm 110 and the spray part 120, thereby realizing the connection between the swing arm 110 and the spray part 120. This connection method has a stable structure and is easy to form.

[0147] Of course, at least one of the second swing arm interface portion 111b and the third swing arm interface portion 111c can be equivalent to the slot structure 150 included in the swing arm interface 111, and the second installation interface portion 121b and the third installation interface portion 121c can be equivalent to the hook structure 140 included in the spray part 120. Similarly, the hook structure 140 is located in the slot structure 150, locking the relative position of the hook plate part 112 and the spray part 120.

[0148] In some examples, one or more column structures may be provided on the hook plate, and a hook structure 140 or a slot structure 150 may be provided on the column structure. The specific configuration is based on actual use and is not specifically limited here.

[0149] Through the technical solution, a stable connection between the hook plate 112 and the spraying member 120 can be achieved, which is convenient for operators to install.

[0150] In some embodiments, see Fig.12 The shell connection port 122 includes: a first shell connection port portion 122a and a second shell connection port portion 122b.

[0151] In order to better stably connect the cover member 130 with the spray member 120, the first shell connection port 122a is arranged at the third installation position of the spray member 120, so that when the cover interface 131 of the cover member 130 is combined with the shell connection port 122 of the spray member 120, the relative position of the spray member 120 and the cover member 130 is limited;

[0152] The second shell connection opening 122 b is disposed at the fourth installation position of the spray component 120 , so that when the cover interface 131 is combined with the shell connection opening 122 , the relative positions of the spray component 120 and the cover component 130 are locked.

[0153] When the cover interface 131 of the cover component 130 is combined with the shell connecting port 122 of the spray component 120, the relative position of the spray component 120 and the cover component 130 is limited in order to enable the cover component 130 to rotate relative to the spray component 120. During the assembly process, after the cover component 130 is rotated relative to the spray component 120 to make the cover interface 131 combined with the shell connecting port 122, the second shell connecting port 122b is used to lock the relative position of the spray component 120 and the cover component 130, thereby completing the connection between the spray component 120 and the cover component 130.

[0154] The third installation position is close to the first installation position on the spray element 120 , and the fourth installation position is close to the second installation position on the spray element 120 .

[0155] In some embodiments, the cover interface 131 includes a first cover interface portion 131 a and a second cover interface portion 131 b .

[0156] See also Figure 21 to Figure 24 The first cover interface portion 131a is arranged at the first shell connection position of the cover member 130, so that when the cover interface 131 is combined with the shell connection port 122, it can form a movable connection with the first shell connection port portion 122a; the second cover interface portion 131b is arranged at the second shell connection position of the cover member 130, so that when the cover interface 131 is combined with the shell connection port 122, it can form a fixed connection with the second shell connection port portion 122b.

[0157] When the cover interface 131 on the cover component 130 is combined with the shell connection port 122 on the spray component 120, the first cover interface portion 131a can be connected with the first shell connection port portion 122a, and the first cover interface portion 131a can also rotate relative to the first shell connection port portion 122a. When the second cover interface portion 131b is rotated to be combined with the second shell connection port portion 122b, the cover component 130 and the spray component 120 are installed in place.

[0158] The first shell connection port 122a is equivalent to the outer peripheral wall of the nozzle body, the second shell connection port 122b is equivalent to the hook structure 140 of the shell connection port 122, the first cover interface portion 131a is equivalent to a slot structure 150 included in the cover component 130, and the second cover interface portion 131b is equivalent to the hook structure 140 included in the cover component 130.

[0159] After the outer wall surface of the nozzle body and the slot on the cover component 130 form a movable connection, the cover component 130 rotates relative to the spray component 120. When it rotates to the point where the hook structure 140 on the cover component 130 presses against the hook structure 140 on the spray component 120, the cover component 130 and the spray component 120 are installed in place, thereby achieving the assembly of the cover component 130 and the spray component 120.

[0160] Through the technical solution, a stable connection between the cover member 130 and the spray member 120 is achieved, which is convenient for operators to install.

[0161] In some embodiments, the cover member 130 is provided with an assembly opening 13g and a spray opening 13d, and the assembly opening 13g and the spray opening 13d are arranged at different positions in the accommodating space 13e.

[0162] The assembly opening 13g opens the accommodating space 13e in the assembly direction with the spraying member 120, so that the assembly of the cover member 130 and the spraying member 120 is convenient.

[0163] The assembly opening 13 g is equivalent to the first cover interface portion 131 a , which is equivalent to a slot structure 150 included in the cover member 130 , so that the cover member 130 and the spray member 120 are rotatably connected.

[0164] In the example, the spray opening 13 d opens the accommodation space 13 e in the spray direction of the spray member 120 , which is the spray direction of the cleaning medium sprayed from the holes on the nozzle structure 123 .

[0165] In the example, the nozzle structure 123 on the spray member 120 can be provided with one, two, three, or more. The specific number is set according to the actual use requirements of the wiper arm 10 and is not limited here.

[0166] In the example, when the cover member 130 is provided with more than one spray opening 13 d , at least two spray openings 13 d are arranged in different directions, so as to meet the requirements of different spray directions of the nozzle structures 123 of different spray members 120 .

[0167] As an alternative, see Figures 10 to 12 Taking the spray part 120 having three nozzle structures 123 as an example, the directions of the three nozzle structures 123 are all different. In the spraying direction of two of the nozzle structures 123, an L-shaped spraying opening 13d is set on the cover part 130, and in the spraying direction of the other nozzle structure 123, a hole-shaped spraying opening 13d is set.

[0168] In some embodiments, the cover member 130 includes a limiting structure 132 for enclosing a spray opening 13d.

[0169] The limiting structure 132 has a limiting surface 132 a , so that when the spraying member 120 and the covering member 130 form a whole, the limiting surface 132 a contacts the peripheral wall surface of the nozzle body of the nozzle structure 123 .

[0170] As an optional solution, the limiting surface 132 a is configured as a smoothly transitioned arc surface to better match the nozzle structure 123 of the spraying member 120 .

[0171] As another optional solution, the limiting surface 132a is set as a plane to facilitate molding.

[0172] As an optional solution, the cover member 130 is further provided with a guide block 133, and the spray member 120 is provided with a guide groove 124. When the cover member 130 rotates relative to the spray member 120, the guide block 133 is located in the guide groove 124 to play a guiding role.

[0173] After the assembly is completed, it can also play a role of limiting the cover member 130 and the spray member 120, so that the cover member 130 and the spray member 120 can be assembled more beautifully.

[0174] In some embodiments, the wiper arm 10 further includes a rotation connection structure 180 , which is disposed between the wiper rod 113 , the wiper arm rod 114 and the rod head 115 , and is used to form a rotation connection between the wiper arm rod 114 and the rod head 115 .

[0175] The rotation connection structure 180 includes a rotation connection portion 181 disposed between the scraper arm rod 114 and the rod head 115 so that the rod head 115 and the scraper arm rod 114 are rotationally connected.

[0176] The rotation connection portion 181 is equivalent to a rotation axis, connecting the scraper arm rod 114 and the rod head 115 , so that the scraper arm rod 114 and the rod head 115 form a rotation connection.

[0177] The part of the scraper arm rod 114 near the rod head 115 includes two relatively arranged rotating mounting arms, and rotating positioning holes arranged coaxially are opened on the two rotating mounting arms. A rotating connecting hole arranged coaxially is set on the part of the rod head 115 near the scraper arm rod 114, and the rotating positioning hole and the rotating connecting hole are connected by a rotating shaft, so that the scraper arm rod 114 and the rod head 115 form a rotating connection.

[0178] In order to further improve the overall structural stability of the wiper arm 10 during the rotation of the hook plate 112, the wiper rod 113 and the wiper arm rod 114 relative to the rod head 115, in some embodiments, see Figure 5 The rotating connection structure 180 also includes: a positioning connection part 182 and an elastic connection part 183.

[0179] The positioning connection portion 182 is connected to the rod head 115 .

[0180] The positioning connection portion 182 is equivalent to a positioning connection shaft. Two positioning connection holes that are opposite to each other can be opened on the rod head 115 at a position avoiding the rotation connection hole, and the two ends of the positioning connection shaft are respectively extended into the positioning connection holes.

[0181] The elastic connection portion 183 has two opposite ends, one of which is connected to the positioning connection portion 182 , and the other end passes through the scraper rod 113 and is connected to the scraper arm rod 114 .

[0182] Both the hook plate 112 and the scraper arm rod 114 have an insertion space 11f. Part of the scraper rod 113 is inserted into the insertion space 11f of the scraper arm rod 114, and then the part of the scraper arm rod 114 is connected to the part of the scraper rod 113 by using fasteners. The part of the scraper rod 113 is located in the insertion space 11f of the hook plate 112, and then the part of the scraper rod 113 is connected to the part of the hook plate 112 by using fasteners, thereby completing the fixed connection between the hook plate 112, the scraper rod 113 and the scraper arm rod 114.

[0183] See also Figure 2 The elastic connecting part 183 is equivalent to the combination of a spring and a C-shaped ring. One end of the spring is hung on the C-shaped ring, and the other end of the spring is passed through the scraper rod 113 and connected to the scraper arm rod 114. The C-shaped ring is hung on the positioning connecting shaft. This setting method is stable in rotation.

[0184] As an optional solution, the elastic connection part 183 can also be set as a whole spring, one end of the spring is hung on the positioning connection shaft, and the other end passes through the scraper rod 113 and is connected to the scraper arm rod 114.

[0185] In order to further improve the integrity of the overall structure of the wiper arm 10 , in some embodiments, the wiper arm 10 further includes a wiper blade attachment 190 .

[0186] The swing arm 110 also has an accessory interface 116 which is different from the swing arm interface 111, which is equivalent to setting the accessory interface 116 on the hook plate 112. The scraper blade accessory 190 has a scraper blade interface 191 which can cooperate with the accessory interface 116. When the accessory interface 116 is combined with the scraper blade structure, part of the scraper blade accessory 190 is located in the insertion space 11f, thereby making the scraper blade accessory 190 stably connected to the hook plate 112.

[0187] At least one of the accessory interface 116 and the blade interface 191 includes a hook structure 140 and / or a slot structure 150 .

[0188] See also Figure 6 , Figure 8 and Fig. 9The accessory interface 116 includes a first accessory interface portion 116a, and the scraper blade interface 191 includes a first scraper blade interface portion 191a. The first accessory interface portion 116a and the first scraper blade interface portion 191a are fixedly connected.

[0189] The first attachment interface portion 116 a is equivalent to the hook structure 140 , and the first scraper blade interface portion 191 a is equivalent to the slot structure 150 . The hook structure 140 is located in the slot structure 150 , so that the scraper blade attachment 190 is connected to the hook plate 112 .

[0190] When the scraper blade attachment 190 is connected to the hook plate member 112, the scraper blade attachment 190 is slid into the insertion space 11f, and after the first attachment interface portion 116a is connected to the first scraper blade interface portion 191a, the connection between the scraper blade attachment 190 and the hook plate member 112 is completed.

[0191] In some embodiments, a portion of the scraper blade attachment 190 close to the scraper rod 113 is provided with a pressing portion 192 , and the pressing portion 192 is in contact with the hook plate 112 .

[0192] When it is necessary to separate the first accessory interface portion 116a from the first scraper blade interface portion 191a, a second force can be applied to the pressing portion 192, thereby applying a force to the scraper blade attachment 190 as a whole. Under the action of the force, the first accessory interface portion 116a is separated from the first scraper blade interface portion 191a, thereby separating the scraper blade attachment 190 from the hook plate portion 112.
