Description

Technical Field

[0001] The invention relates to a wiper joint and a wiper adapted to the wiper joint. Background Art

[0002] like Figure 1 As shown, PCT patent application international publication number WO2018 / 162056 A1, international publication date September 13, 2018 discloses a wiper arm 6', the wiper arm 6' having two side edges 10', the bottoms of the two side edges 10' respectively having two inwardly bent first hooks 11' and second hooks 12'; at the same time, it discloses a windshield wiper device 1' for adapting the wiper arm 6', which includes an elongated wiper blade 2' made of flexible material, which can be placed adjacent to the windshield to be wiped, the wiper blade 2' includes at least one longitudinal groove 3', an elastic supporting component 4' is arranged in the longitudinal groove 3', the windshield wiper device 1' includes a connecting device 5' for a swing arm 6', wherein the swing arm 6' can be pivotally connected to the swing arm 6' around a pivot axis near one end. The connecting device 5' also has a wiper connector 7', and the connecting device 5' and the wiper connector 7' have mutually cooperating pivot devices for pivotally connecting the wiper connector 7' to the connecting device 5', and the wiper connector 7' can pivot between wiping positions, and the wiper connector 7' is locked on the swing arm 6', wherein at least one first hook 11' laterally inwardly arranged on the swing arm 6' is clamped behind the side wall 13' of the wiper connector 7', and in a maintenance state, the two side walls 13' of the wiper connector 7' are allowed to bend laterally inwardly so as to release the side wall 13' of the wiper connector 7' from the first hook 11' of the swing arm 6'. However, in order to allow the extended first hook 11' of the swing arm 6' to be inserted into the side wall 13' of the wiper joint 7', the side wall 13' must have a certain elasticity at least in the area cooperating with the extended first hook 11'. Through the interference fit between the first hook 11' of the swing arm 6' and the side wall 13' of the wiper joint 7', the side wall 13' is forced to bend laterally inward until the first hook 11' sinks to the bottom of the side wall 13' to complete the snap fit with the wiper joint 7'; a stopper 14' is also provided at the front end of the bottom of the two side walls 13' of the wiper joint 7', the front end of the first hook 11' of the swing arm 6' abuts against the stopper 14', and the rear end abuts against the abutment 131' at the bottom of the side wall 13', thereby limiting the swing arm 6' from moving forward and backward relative to the wiper joint 7'.

[0003] With the above solution, the side wall 13' of the wiper joint 7' has elasticity in the areas A and B where the first hook 11' and the second hook 12' of the swing arm 6' cooperate with each other. Once the swing arm 6' and the wiper joint 7' are installed in place, the first hook 11' and the second hook 12' of the swing arm 6' are used to cooperate with the bottom end surface 131' of the side wall 13' of the wiper joint 7' during production and manufacturing. Figure 2-1 ), there may be a certain angle α between the mating end surface of the first hook 11' or the second hook 12' and the bottom end surface 131' of the side wall 13' (e.g. Figure 2-2 ), once the angle α is too large, the first hook 11' or the second hook 12' of the swing arm 6' will generate an upward component force relative to the wiper joint 7' when the swing arm 6' drives the windshield wiper device 1' to wipe. Since the area A and the area B of the two side walls 13' of the wiper joint 7' for anchoring the first hook 11' or the second hook 12' are elastic, the first hook 11' or the second hook 12' of the swing arm 6' is very easy to be separated from the area A, B of the side wall 13' during the wiping process (see Figure 1 and Figure 2-3 ), thus the wiper blade 2 ´cannot be driven to wipe the windshield, affecting driving safety. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems in the above-mentioned technology to a certain extent. To this end, one object of the present invention is to provide a wiper joint that is not easy to separate from the wiper arm adapted thereto.

[0005] A second object of the present invention is to provide a wiper adapted to the wiper connector.

[0006] To achieve the first object of the present invention, the first embodiment of the present invention provides a wiper connector, which is used to ensure the connection between the wiper arm and the connecting base of the wiper body; the bottom of the two side walls of the wiper arm are respectively provided with two first hooks and a second hook bent inwardly; the wiper connector comprises an operating component and a connector body, the operating component has a connecting portion and two cantilevers, the connecting portion is connected to the top of the two cantilevers, and the two cantilevers are respectively arranged opposite to the two side walls of the connector body; the connecting portion is integrally connected to the top wall of the connector body, there is a gap between the cantilever and the side wall of the connector body, the cantilever can be elastically deformed inwardly under the action of an external force, and the bottom of the cantilever has a locking portion;

[0007] The two side walls of the joint body are respectively provided with two first clamping parts, two blocking parts, two sliding grooves and two second clamping parts from front to back; the first clamping part is arranged between the clamping part and the blocking part; the side wall cannot be elastically deformed laterally inward at least in the areas C and D located vertically upward from the first clamping part and the second clamping part; when in the locked state, the first hook and the second hook slide down and move backward along the cantilever and the sliding groove respectively, and are respectively buckled on the first clamping part and the second clamping part, and the first hook is clamped between the clamping part and the blocking part; when in the unlocked state, the cantilever is pressed inward, and the first hook and the second hook slide forward to the outer wall of the clamping part and the sliding groove of the cantilever respectively.

[0008] Based on the above design, the cantilever is independent of the joint body. The cantilever can be elastically deformed, while the joint body cannot be elastically deformed, so that the first hook and the second hook of the wiper arm can be firmly buckled on the first holding part and the second holding part of the wiper joint and are not easy to detach.

[0009] In addition, a wiper connector according to the above embodiment of the present invention may also have the following additional technical features:

[0010] The bottoms of the two side walls of the connector body protrude outwards to form two protrusions, which are arranged adjacent to the rear of the second clamping portion; the rear end of the second hook abuts against the protrusions to limit the second hook, thereby further restricting the wiper arm from moving forward and backward relative to the wiper connector.

[0011] The front end of the cantilever is also provided with two pressing pieces protruding outward. When the pressing pieces are pressed inward, the cantilever is compressed inward along with the pressing pieces. The setting of the pressing pieces can be operated more conveniently, so that the cantilever is compressed and deformed inward, allowing the wiper arm to be unlocked from the joint body.

[0012] The pressing piece is located at the front end of the bottom of the cantilever, and the inner side of the front end of the pressing piece is also fixed by a supporting piece, and the supporting piece is composed of a hypotenuse and two vertical sides located on both sides of the front end of the hypotenuse, and the hypotenuse and the vertical sides form a gap with the cantilever on the adjacent side, that is, there is a gap between the cantilever and the hypotenuse and the vertical sides, so that the cantilever is basically in a suspended state with only the top fixed, and the left and right sides are independent, which makes it easier to move inward with the pressing piece without being restrained by surrounding attachments; one end of the pressing piece is connected to the top of the vertical side, and the other end is connected to the front end of the bottom of the cantilever. When a force is applied to the pressing piece, the pressing piece will always move inward in a horizontal direction without any deviation or skewing.

[0013] The thickness of the cantilever is smaller than the thickness of the side wall of the joint body, which facilitates the elastic deformation of the cantilever.

[0014] The cantilever includes a first inclined surface; the width of the first inclined surface gradually widens from top to bottom, and the distance between the two tops of the first inclined surfaces is smaller than the distance between the free end surfaces of the two first hooks, so as to facilitate the two first hooks to slide into the first inclined surface; when the two stopping portions are elastically deformed laterally inward without external force, the two stopping portions form a blockage for the first hook at least in the width direction of the joint body to prevent the first hook from sliding forward relative to the joint body.

[0015] A second inclined surface is provided between the first inclined surface and the clamping portion. The second inclined surface plays a transition role, and guides elastic deformation when the first hook slides into the second inclined surface, so as to facilitate the first hook to slide into the bottom end of the clamping portion. A chamfer is provided at the bottom end of the slide groove on one side close to the second stop portion, so as to facilitate the second hook to move backward.

[0016] The blocking portion is a convex strip arranged at the bottom of the side wall and extending along the length direction thereof. To achieve the second object of the present invention, the second aspect of the present invention proposes a wiper, comprising a wiper body, the wiper body at least consisting of a wiper rubber strip fixing mechanism, a rubber strip and a connecting base, the rubber strip is fixed below the wiper rubber strip fixing mechanism, the connecting base is arranged above the middle of the wiper rubber strip fixing mechanism, the two side edges of the connecting base at least have a pivot fitting portion, and it also includes the above-mentioned wiper joint, the two side walls of the wiper joint have a pivot connection portion, and the wiper joint can be swingably arranged on the connecting base along the length direction of the wiper body by the pivot connection between the pivot connection portions of the two side walls of the wiper joint and the pivot fitting portions on the connecting base.

[0017] Based on the above design, when the wiper arm drives the wiper to wipe, the wiper arm and the wiper joint are not easy to separate from each other, the quality is reliable, and the use is safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Example 1

[0034] See also Figure 5 A wiper joint 100 is used to ensure that the wiper arm 200 and the wiper body 300 (see Figure 8 ) is connected to the connecting base 303; the bottom of the two side walls of the wiper arm 200 respectively has a first hook 202 and a second hook 201 bent inwardly.

[0035] Please refer to Figure 3-4 and Figure 6 The wiper connector 100 includes an operating component 2 and a connector body 1; the operating component 2 has a connecting portion 21 and two cantilevers 22, the connecting portion 21 is connected to the top of the two cantilevers 22, and the two cantilevers 22 are respectively arranged opposite to the two side walls 10 of the connector body 1; the connecting portion 21 is integrally connected to the top wall 20 of the connector body 1, and there is a gap between the cantilever 22 and the side wall 10 of the connector body 1, the cantilever 22 can be elastically deformed inward under the action of external force, and the bottom of the cantilever 22 has a locking portion 222; the setting of the gap between the cantilever 22 and the side wall 10 of the connector body 1 makes the cantilever 22 It can be independent of the connector body 1. In the present embodiment, the cantilever 22 is only provided with a fixed point at the top, and the thickness of the cantilever 22 is relatively thin, thereby ensuring that the cantilever 22 can realize elastic deformation. At the same time, by increasing the thickness of the side wall 10 of the main body or adding a number of reinforcing ribs on the side wall 10 of the main body, it is ensured that the side wall 10 of the main body cannot be elastically deformed in the areas C and D that match the first hook 202 and the second hook 201 of the wiper arm 200. In the present embodiment, for the convenience of processing and manufacturing, the entire side wall 10 of the main body cannot be elastically deformed, so that the first hook 202 and the second hook 201 of the wiper arm 200 are not easy to separate from the connector body 1.

[0036] Please refer to Figure 3-6The connector body 1 is formed by two side walls 10 and a top wall 20 to form a connector body 1 with a U-shaped cross section. The two side walls 10 have at least one pivot connection portion X, by which the wiper connector 100 can be swingably set on the connecting base 303 along the length direction of the wiper body 300; the two side walls 10 of the connector body 1 have two first clamping portions 13, two blocking portions 15, two slide grooves 11 and two second clamping portions 12 from front to back; the first clamping portion 13, the blocking portion 15 and the second clamping portion 12 are all located at the bottom of the side wall 10, and the first clamping portion 13 is arranged between the stop portion 222 and the blocking portion 15; the blocking portion 15 is a convex strip arranged at the bottom of the side wall 10 and extending along the length direction thereof. The design of the convex strip can not only limit the first hook 202, but also enhance the strength of the side wall 10 of the connector body 1. The slide slot 11 is longitudinally arranged at the rear of the side wall 10 of the connector body 1 , and the second retaining portion 12 is arranged behind the slide slot 11 ; a chamfer 16 is arranged at the bottom end of the slide slot 11 near the second retaining portion 12 to facilitate the second hook 201 to move backward.

[0037] Please refer to Figure 3-7 The side wall 10 of the joint body 1 cannot be elastically deformed inwardly at least in the vertically upward areas C and D of the first clamping portion 13 and the second clamping portion 12, so that the first hook 202 and the second hook 201 of the wiper arm 200 are not easy to escape from the areas C and D; when in the locked state, the first hook 202 and the second hook 201 slide down and move backward along the cantilever 22 and the slide groove 11 respectively, and are buckled on the first clamping portion 13 and the second clamping portion 12 respectively, The first hook 202 is clamped between the locking portion 222 and the blocking portion 15, so as to restrict the wiper arm 200 from moving forward and backward relative to the wiper connector 100. When the wiper arm 200 is in the unlocked state, the cantilever arm 22 is pressed inward, and the first hook 202 and the second hook 201 slide forward to the outer wall of the locking portion 222 of the cantilever arm 22 and the slide groove 11, respectively. At this time, the locking portion 222 of the cantilever arm 22 and the first hook 202 are misaligned with each other, so that the wiper arm 200 slides to the outer wall of the locking portion 222 (see FIG. Figure 7 ), the wiper arm 200 can be separated from the wiper connector 100 by simply pulling the wiper arm 200 upwards.

[0038] Please refer to Figure 3 and Figure 6 The bottoms of the two side walls 10 of the connector body 1 protrude outwards to form two protrusions 14, and the protrusions 14 are arranged immediately behind the second holding portion 12; the rear end of the second hook 201 abuts against the protrusions 14 to limit the second hook 201, thereby further restricting the wiper arm 200 from moving forward and backward relative to the wiper connector 100.

[0039] Please refer to Figure 3 and Figure 6 The front end of the cantilever 22 is also provided with two pressing pieces 23 protruding outward. When the pressing pieces 23 are pressed inward, the cantilever 22 is compressed inward along with the pressing pieces 23. The setting of the pressing pieces 23 can be operated more conveniently, so that the cantilever 22 is compressed and deformed inward, allowing the wiper arm 200 to be unlocked from the joint body 1. The pressing piece 23 is located at the front end of the bottom of the cantilever 22, and the inner side of the front end of the pressing piece 23 is also fixed by a supporting piece 24, and the supporting piece is composed of a hypotenuse 24a and two vertical sides 24b located on both sides of the front end of the hypotenuse, and the hypotenuse 24a and the vertical side 24b form a gap with the cantilever 22 on the adjacent side, that is, there is a gap 25 between the cantilever 22 and the hypotenuse 24a and the vertical side 24b, so that the cantilever 22 is basically in a suspended state with only the top fixed, and the left and right sides are independent, which makes it easier to move inward with the pressing piece 23 without being restrained by the surrounding attachments; one end of the pressing piece 23 is connected to the top of the vertical side 24b, and the other end is connected to the front end of the bottom of the cantilever 22. When a force is applied to the pressing piece 23, the pressing piece 23 will always keep moving inward in a horizontal direction without any deviation or skewing.

[0040] Please refer to Figure 3 and Figure 6-7 The cantilever 22 includes a first inclined surface 221a; the width of the first inclined surface 221a gradually widens from top to bottom, and the distance between the tops of the two first inclined surfaces 221a is smaller than the distance between the free end surfaces of the two first hooks 202, so as to facilitate the two first hooks 202 to slide into the two first inclined surfaces 221a; when the two stopper portions 222 are not elastically deformed laterally inward by external force, the two stopper portions 222 form a barrier to the first hook 202 at least in the width direction of the connector body 1, preventing the first hook 202 from sliding forward relative to the connector body 1. A second inclined surface 221b is provided between the first inclined surface 221a and the holding portion 222. The second inclined surface 221b plays a transition role, and guides the elastic deformation when the first hook 202 slides into the second inclined surface 221b, so as to facilitate the first hook 202 to slide into the bottom end of the holding portion 222. The function of the holding portion 222 is that when the first hook 202 slides into the holding portion 222, the holding portion 222 elastically bends inwardly. After the first hook 202 moves backward into position, the holding portion 222 resets to restrict the first hook 202 from disengaging. When unlocking, the holding portion 222 is compressed and deformed inwardly and no longer holds the first hook 202, so that the first hook 202 can slide forward to the outer wall of the holding portion 222. In this way, the wiper arm 200 can be separated from the wiper connector 100 by simply pulling up.
