Detailed Implementation

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figure 1-3As shown, the novel multifunctional wiper connector of this embodiment includes a connecting base 100, a connecting outer cover 200, and a wiper blade holder 300. The connecting outer cover 200 is detachably mounted on the connecting base 100, and the connecting base 100 is detachably mounted on the wiper blade holder 300. A first positioning hole 201 penetrating the connecting outer cover 200 is provided on the connecting outer cover 200, and a second positioning hole 101 penetrating the connecting base 100 is provided on the connecting base 100. The first positioning hole 201 and the second positioning hole 101 are coaxially arranged, forming insertion holes for the ends of the first wiper arm and the second wiper arm 600 to be inserted. The outer end of the first positioning hole 201 is a countersunk hole structure. This countersunk hole structure design provides a clearance groove for the insertion and installation of the second wiper arm 600. The connecting outer cover 200 has a limiting groove 202 for limiting the first wiper arm. The limiting groove 202 penetrates the upper side wall of the connecting outer cover 200, exposing the upper end face of the connecting seat 100. A gap is left between the inner side wall of the connecting outer cover 200 and the outer side wall of the connecting seat 100 at the limiting groove 202 to limit the second wiper arm 600. The connecting seat 100 has a limiting platform 102 and a positioning groove 103 for limiting the connecting outer cover 200 or the third wiper arm 700. The connecting outer cover 200 has a limiting block 203 that cooperates with the limiting platform 102 and a positioning block 204 that cooperates with the positioning groove 103. Specifically, the limiting platform 102 is located below the rear end of the connecting seat 100, and the limiting block 203 is located at the bottom of the rear end of the connecting outer cover 200. When the connecting outer cover 200 is placed on the connecting seat 100, the limiting block 203 is engaged with the limiting platform 102. The front side walls of the connecting seat 100 are provided with elastic arms 104, the front end of which is a pressing block 105. A positioning groove 103 is located behind the pressing block 105. The positioning block 204 is located on the inner wall of the two side walls at the front end of the connecting outer cover 200. When the connecting outer cover 200 is placed on the connecting seat 100, the positioning block 204 is engaged with the positioning groove 103. The front end of the connecting seat 100 is provided with a slot 106 for inserting the fourth wiper arm 800, and the slot 106 is provided with a third positioning hole 107 for positioning the fourth wiper arm 800. The connector 100 and the outer cover 200 of this invention are equipped with various connection structures to adapt to various wiper arm mounts, thereby improving the applicability of this novel multifunctional wiper connector. The positioning groove 103 is a recessed groove; its upper and lower sidewalls restrict the vertical movement of the positioning block 204, and its front and rear sidewalls restrict the forward and backward movement of the positioning block 204, thus ensuring that the positioning block 204 is more stably and reliably positioned within the positioning groove 103, avoiding the risk of detachment. Furthermore, the positioning groove 103 can be used by both the positioning block 204 of the outer cover 200 and the third positioning block 702 of the third wiper arm 700, offering strong versatility and ease of use.

[0027] To facilitate the installation between the connecting seat 100 and the connecting cover 200, a first guide groove 108 is provided on the connecting seat 100 above the positioning groove 103. The bottom end of the guide groove is connected to the positioning groove 103. The first guide groove 108 is used to guide the positioning block 204.

[0028] Combination Figure 4 As can be seen, the inner wall of the connecting outer cover 200 located at the first positioning hole 201 is provided with an inwardly protruding limiting wall 205. The limiting wall 205 allows the connecting outer cover 200 and the outer surface of the side wall of the connecting seat 100 to maintain a gap while still being stably engaged.

[0029] Combination Figure 2 and Figure 5 The connecting seat 100 has a fixing hole 109 on its side wall, and the wiper blade holder 300 has a connecting plate 301. The connecting plate 301 has a retaining shaft 302, and the fixing hole 109 is hinged to the end of the retaining shaft 302. A second guide groove 110 is provided on the inner side of the side wall of the connecting seat 100, and the second guide groove 110 connects to the inner end of the fixing hole 109. The second guide groove 110 guides the end of the retaining shaft 302 when the connecting seat 100 and the wiper blade holder 300 are hinged. Additionally, the connecting plate 301 has an anti-misalignment and anti-sway hole 303, and the inner end of the upper side wall of the connecting seat 100 has a protrusion 111. The protrusion 111 is inserted into the anti-misalignment and anti-sway hole 303 when the connecting seat 100 is installed on the connecting plate 301, and the shape of the protrusion 111 matches the anti-misalignment and anti-sway hole 303.

[0030] In this embodiment, the disassembly process of connecting the outer cover 200 and the connecting seat 100 is as follows: Figure 3 As shown: First, press the pressing block 105 on the elastic arm 104 to bend the elastic arm 104 inward, at which point the positioning block 204 disengages from the positioning groove 103; then, flip the connecting outer cover 200 backward to detach it from the rear end of the connecting seat 100, thus completely disassembling it. The installation process of the connecting outer cover 200 and the connecting seat 100 is achieved by reversing the operation: slide the connecting outer cover 200 onto the connecting seat 100 from the rear end, so that the limiting block 203 abuts against the limiting platform 102; then flip it forward so that the positioning block 204 is inserted into the positioning groove 103 along the first guide slope, completing the assembly.

[0031] The following detailed implementation process illustrates the connection process of the novel multifunctional wiper connector of the present invention for different wiper arm mounts. Example 1:

[0032] like Figure 6As shown, in this embodiment, a first insert shaft 501 is provided on the side of the rear end of the first wiper arm, and a first snap-fit ​​arm 502 is provided above the rear end. A first snap-fit ​​plate 503 is connected to the free end of the first snap-fit ​​arm 502. During installation, the first wiper arm is placed diagonally upward, and the first insert shaft 501 is inserted into the insertion hole through the connecting outer cover 200. Then, the first wiper arm is rotated downward so that the first snap-fit ​​arm 502 is snapped into the limiting groove 202. At this time, the first snap-fit ​​plate 503 is snapped onto the outer surface of the other side wall of the connecting outer cover 200, forming a left and right limit with the first wiper arm clamping the connecting outer cover 200 in the middle. At the same time, the insert shaft and the insertion hole cooperate to achieve the upper and lower limit, thereby completing the installation of the first wiper arm. It should be noted that in this embodiment, the connecting outer cover 200 and the connecting seat 100 need to be installed first, and then the first wiper arm is installed. Example 2:

[0033] like Figure 7 As shown, the installation method of this embodiment is similar to that of Embodiment 1. The difference is that the second snap-fit ​​arm 602 of the second wiper arm 600 is shorter, and its length extends from the outer surface of one side wall of the connecting outer cover 200 to the inner surface of the other side wall. A second snap-fit ​​plate 603 is provided at the free end of the second snap-fit ​​arm 602. After installation, the second insertion shaft 601 of the second wiper arm 600 is inserted into the insertion interface, and the second snap-fit ​​plate 603 is inserted into the gap between the inner surface of the side wall of the connecting outer cover 200 and the outer surface of the side wall of the connecting seat 100 to achieve left and right limit of the second wiper arm 600. Other aspects are the same as in the embodiment. For the specific installation process, please refer to Embodiment 1, which will not be repeated here. Example 3:

[0034] like Figure 8 As shown, in this embodiment, the installation of the third wiper arm 700 does not require the connection of the outer cover 200. Therefore, it is necessary to remove the connection of the outer cover 200. The disassembly process is described in [link to disassembly process]. Figure 3 The end structure of the third wiper arm 700 is the same as that of the connecting outer cover 200 in principle. A third limiting block 701 is provided at the bottom of its rear end, and a third positioning block 702 is provided at the front end. Its installation principle is the same as that of the connecting outer cover 200 and the connecting seat 100, and will not be described in detail here. Example 4:

[0035] like Figure 9 As shown, in this embodiment, the rear end of the fourth wiper arm 800 is a columnar structure with a protrusion 801 on it. During installation, the rear end of the fourth wiper arm 800 is inserted into the slot 106 at the front end of the connector 100. The upper sidewall of the slot 106 is lifted appropriately to deform it, so that the protrusion 801 can enter the slot 106 and eventually reach below the third positioning hole 107. At this time, the external force applied to the upper sidewall of the slot 106 is released, and the upper sidewall of the slot 106 is pressed down under the action of elastic force, which snaps the protrusion 801 into the third positioning hole 107, thus completing the installation of the fourth wiper arm 800.

[0036] The novel multi-functional wiper connector of this invention enables the installation of various wiper arm mounts, greatly improving the adaptability of the new multi-functional wiper connector, and ensuring stable and reliable installation.
