Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a water cutter and vehicle. Background Technology

[0002] A water-sealing device, as a sealing component, is an important part of a car door. Water-sealing devices typically have an end cap, which is integrally molded with a snap-fit ​​mechanism. This snap-fit ​​mechanism, which engages with the door sheet metal, provides an installation positioning reference for the water-sealing device, preventing the end cap from lifting and causing leakage. In existing technology, the end cap and snap-fit ​​are integrally molded, and the end cap is fixedly connected to the water-sealing device body. This means that if the snap-fit ​​is damaged during maintenance, the entire water-sealing device needs to be replaced, resulting in material waste and increased vehicle costs. Utility Model Content

[0003] In view of this, this application provides a water cutter and vehicle to solve the problem in the prior art that the entire water cutter needs to be replaced after the end-joint corner clip is damaged.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A water cutter, comprising:

[0006] end-to-end angle;

[0007] The buckle includes a connecting part and a snap-fit ​​part that are fixedly connected. The connecting part is detachably connected to the end corner, and the snap-fit ​​part is used to snap-fit ​​with the sheet metal of the vehicle door.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] like Figures 1-6 As shown, this application embodiment provides a water cutter, which can be an external water cutter or an internal water cutter. The water cutter includes an end joint angle 100 and a buckle 200, and the water cutter also includes a water cutter body.

[0036] The end joint 100 is fixedly connected to the water-cutting body. Optionally, the end joint 100 can be injection molded to form an integral structure with the water-cutting body, or the end joint 100 can be fixedly connected to the water-cutting body by means of bonding or other methods.

[0037] The buckle 200 includes a connecting part 210 and a snap-fit ​​part 220 that are fixedly connected. The connecting part 210 and the snap-fit ​​part 220 can be fixedly connected by means of adhesive bonding, bolt connection, etc. The connecting part 210 and the snap-fit ​​part 220 can also be an integrally formed structure. The connecting part 210 is detachably connected to the end corner 100. At least a portion of the snap-fit ​​part 220 extends beyond the end corner 100 and is used to snap-fit ​​with the positioning hole on the door sheet metal 400.

[0038] In this embodiment, the end joint 100 and the clip 200 are separate structures. The clip 200 and the end joint 100 are detachable. If the clip 200 is damaged after long-term use, or if it is damaged during water cutter maintenance or removal, the clip 200 can be removed from the end joint 100 and replaced with a new clip 200. This eliminates the need to replace the end joint 100 and the entire water cutter body, alleviating the waste caused by replacing the entire water cutter and reducing vehicle costs. Therefore, the water cutter provided in this embodiment solves the problem in the prior art where the entire water cutter needs to be replaced after the end joint clip is damaged.

[0039] There are several ways to detachably connect the connecting part 210 to the end corner 100. In one optional embodiment, the connecting part 210 can be detachably connected to the end corner 100 by bolts.

[0040] In another alternative embodiment, the end joint 100 may be fixedly provided with a retainer 300. The retainer 300 may be fixedly connected to the end joint 100 by means of bolt connection, adhesive connection or other means. Alternatively, a portion of the retainer 300 may be embedded in the end joint 100 by injection molding, with a portion extending beyond the end joint 100. The connecting portion 210 may be detachably connected to the portion of the retainer 300 extending beyond the end joint 100, thereby being detachably connected to the end joint 100 through the retainer 300.

[0041] Optionally, the connecting part 210 can be detachably connected to the bracket 300 by bolts, or the connecting part 210 can be snapped into the bracket 300, and at least a portion of the snapping part 220 extends beyond the bracket 300 for snapping into the positioning hole of the door sheet metal 400.

[0042] In this case, the connecting part 210 is connected to the end corner 100 by snap-fit, which facilitates the assembly and disassembly of the connecting part 210 and the end corner 100.

[0043] There are several ways to achieve the connection between the connecting part 210 and the card holder 300.

[0044] In an optional embodiment, the card holder 300 may be provided with a receiving cavity 310, the receiving cavity 310 may have a card hole, the connecting part 210 may extend into the card hole and engage with the card holder 300, and the engaging part 220 is located outside the card hole and is used to engage with the positioning hole on the door sheet metal 400.

[0045] In another alternative embodiment, the card holder 300 may have a receiving cavity 310, which may have an insertion interface 320 and a notch 330. The insertion interface 320 allows the connecting part 210 to be inserted into the receiving cavity 310, and the notch 330 allows the locking part 220 to extend out of the card holder 300. In this structure, the connecting part 210 can be detachably installed on the card holder 300 by insertion, which is simple in structure and convenient in operation.

[0046] Please refer to this again. Figure 3 The notch 330 can be formed on the first side wall 370 of the card holder 300. The opening of the notch 330 can be formed in the insertion interface 320, so that the notch 330 communicates with the insertion interface 320. When assembling the buckle 200 and the card holder 300, the connecting part 210 enters the receiving cavity 310 through the opening of the insertion interface 320 and the notch 330, thus completing the assembly of the buckle 200 and the card holder 300.

[0047] In an optional embodiment, the connecting portion 210 and the receiving cavity 310 can be snapped together by matching their dimensions. For example, the opposite sidewalls of the receiving cavity 310 can clamp the connecting portion 210 to achieve the snap-fit ​​between the connecting portion 210 and the receiving cavity 310.

[0048] In one optional embodiment, the connecting portion 210 and the receiving cavity 310 can also be engaged through limiting cooperation in one or more directions. Alternatively, in another optional embodiment, in addition to being engaged through dimensional cooperation, the connecting portion 210 and the receiving cavity 310 can also be engaged through limiting cooperation in one or more directions.

[0049] By using limiting and cooperating in one or more directions to achieve the snap-fit ​​between the connecting part 210 and the card holder 300, not only can the snap-fit ​​between the two be achieved, but the connection strength and connection stability of the connecting part 210 and the card holder 300 can also be improved, thereby improving the overall structural stability of the water cutter. This also alleviates the problem that the friction force exerted by the glass on the water cutter during the glass lifting process causes the end joint 100 and the buckle 200 to be deformed or even detached from each other due to stress.

[0050] Specifically, the receiving cavity 310 includes a bottom wall opposite to the insertion interface 320. The receiving cavity 310 may have a limiting protrusion 340. In the insertion direction z of the card holder 300 and the latch 200, the connecting part 210 is limited and engaged with the bottom wall. In the opposite direction of the insertion direction z, the connecting part 210 is limited and engaged with the limiting protrusion 340. In this way, in the opposite direction of the insertion direction z, the limiting protrusion 340 blocks the latch 200, making it difficult for the latch 200 to come out of the receiving cavity 310, improving the connection stability after the card holder 300 and the latch 200 are engaged, thereby improving the overall structural stability of the water cutter.

[0051] In this embodiment, the receiving cavity 310 has a U-shaped sidewall forming an opening 330. A limiting protrusion 340 can be disposed on the U-shaped sidewall. There can be two limiting protrusions 340, which can be disposed opposite to each other at the ends of the adjacent insertion interface 320 on the U-shaped sidewall. Of course, the limiting protrusion 340 can also be disposed at other locations within the receiving cavity 310, as long as it can effectively limit the connection portion 210 in the opposite direction of the insertion direction z.

[0052] The buckle 200 has a certain degree of elasticity. When the buckle 200 is in its natural state, along the direction of the line connecting the two limiting protrusions 340 (which may be the first direction x in this embodiment), the size of the area of ​​the buckle 200 opposite to the U-shaped sidewall is slightly larger than the distance between the two limiting protrusions 340.

[0053] During the process of inserting the buckle 200 into the card holder 300, the buckle 200 is first aligned with the insertion interface 320, and then a certain external force is applied to gradually insert the connecting part 210 into the receiving cavity 310. When passing through the area where the limiting protrusion 340 is located, the connecting part 210 and / or the limiting protrusion 340 will deform to adapt to the shape and size of the area where the two limiting protrusions 340 are located, so that the connecting part 210 enters the receiving cavity 310, and the bottom wall of the receiving cavity 310 and the limiting protrusion 340 limit the buckle 200 in the insertion direction z and its opposite direction.

[0054] Similarly, during the process of separating the buckle 200 and the card holder 300, an external force is first applied to the buckle 200 in the opposite direction of the insertion direction z, causing the buckle 200 to move away from the bottom wall. When passing through the area between the two limiting protrusions 340, the connecting part 210 and / or the limiting protrusions 340 will deform to adapt to the shape and size of the area where the two limiting protrusions 340 are located, so that the connecting part 210 can be dislodged from the receiving cavity 310, thus completing the separation of the buckle 200 and the card holder 300.

[0055] In the accommodating cavity 310 and the connecting portion 210, one may be provided with a foolproof protrusion 211, and the other may be provided with a foolproof groove 350. For example, the connecting portion 210 may be provided with a foolproof protrusion 211, and the accommodating cavity 310 may be provided with a foolproof groove 350. Both the foolproof protrusion 211 and the foolproof groove 350 extend along the insertion direction z, and the foolproof protrusion 211 is located within the foolproof groove 350. The cooperation of the foolproof protrusion 211 and the foolproof groove 350 can provide a clear positioning reference for the insertion of the accommodating cavity 310 and the connecting portion 210. The operator can quickly and accurately place the connecting portion 210 in the corresponding position of the accommodating cavity 310, reducing the time spent searching for and adjusting the position, and improving the assembly efficiency of the accommodating cavity 310 and the connecting portion 210.

[0056] The number of anti-mistake protrusions 211 and anti-mistake grooves 350 can be one or more, and they are set in a one-to-one correspondence.

[0057] In a further technical solution, in the first direction x perpendicular to the insertion direction z, the anti-foolproof protrusion 211 can cooperate with the two opposite wall surfaces of the anti-foolproof groove 350 to further improve the connection stability of the card holder 300 and the connecting part 210, thereby improving the overall structural stability of the water cutter.

[0058] In an alternative embodiment, the anti-misalignment groove 350 can be formed by recessing the sidewall of the receiving cavity 310. For example, the receiving cavity 310 includes a first sidewall 370 and a second sidewall disposed opposite to each other, and a notch 330 is formed in the first sidewall 370. The anti-misalignment groove 350 can be formed by recessing the second sidewall in a direction away from the first sidewall 370.

[0059] In another alternative embodiment, the sidewall of the accommodating cavity 310 (e.g., the second sidewall) may be provided with at least two limiting strips 360 extending along the insertion direction z. The sidewall of the accommodating cavity 310 (e.g., the second sidewall) and two adjacent limiting strips 360 form a non-fouling groove 350. The opposing surfaces of the two adjacent limiting strips 360 are limited and engaged with the connecting portion 210 in the first direction x.

[0060] When the anti-fooling groove 350 is formed by recessing the second sidewall in a direction away from the first sidewall 370, the opposite ends of the connecting part 210 abut against the first sidewall 370 and the second sidewall respectively, so that in the second direction y, which is perpendicular to the plane containing the first direction x and the insertion direction z, the connecting part 210 is limited to the first sidewall 370 and the second sidewall, thereby improving the connection stability of the card holder 300 and the connecting part 210, and thus improving the overall structural stability of the water cutter.

[0061] When the side wall (e.g., the second side wall) of the accommodating cavity 310 and the two adjacent limiting strips 360 form an anti-fooling groove 350, the opposite ends of the connecting part 210 abut against the first side wall 370 and the limiting strip 360 respectively, so that in the second direction y, which is perpendicular to the plane containing the first direction x and the insertion direction z, the connecting part 210 is limited and engaged with the first side wall 370 and the limiting strip 360, thereby improving the connection stability of the card holder 300 and the connecting part 210, and thus improving the overall structural stability of the water cutter.

[0062] Of course, when the connecting part 210 is in a limiting engagement with the first side wall 370 and the limiting strip 360, the anti-fooling protrusion 211 of the connecting part 210 can abut against the second side wall, so that in the second direction y, not only can the first side wall 370 and the limiting strip 360 cooperate to limit the connecting part 210, but the first side wall 370 and the second side wall can also cooperate to limit the connecting part 210, thereby improving the connection stability of the card holder 300 and the connecting part 210, and thus improving the overall structural stability of the water cutter.

[0063] As described above, the bottom wall of the accommodating cavity 310 and the limiting protrusion 340 limit the connecting part 210 in the insertion direction z and its opposite direction; the two opposing walls of the anti-fooling groove 350 limit the anti-fooling protrusion 211 in the first direction x perpendicular to the insertion direction z, thereby limiting the connecting part 210 in the first direction x; the first side wall 370 and the limiting strip 360 (or the first side wall 370 and the second side wall) limit the connecting part 210 in the second direction y perpendicular to the plane containing the first direction x and the insertion direction z, thereby realizing the limiting of the connecting part 210 by the accommodating cavity 310 in multiple directions, thus ensuring the connection stability after the buckle 200 and the card seat 300 are engaged, thereby improving the overall structural stability of the water cutter.

[0064] In this embodiment, to facilitate the insertion of the connector 210, the end of the notch 330 adjacent to the insertion interface 320 may have a guide section 331. The guide section 331 may taper along the insertion direction z (that is, expand in the opposite direction of the insertion direction z). In this structure, the guide section 331 is trumpet-shaped, making it easier for the connector 210 to align with the notch 330, providing guidance for the insertion of the connector 210, reducing the difficulty of alignment, and reducing the risk of insertion failure or damage to the connector 210 or the card holder 300 due to alignment deviation.

[0065] The connecting part 210 may have an annular groove 212, and the area of ​​the notch 330 formed by the first sidewall 370 can extend into the annular groove 212. In this structure, the two opposite sidewalls of the annular groove 212 can clamp the area of ​​the notch 330 formed by the first sidewall 370, thereby further improving the connection stability between the connecting part 210 and the card holder 300, and thus improving the overall structural stability of the water cutter.

[0066] Of course, in other alternative embodiments, the dimensions of the portion of the connecting portion 210 located within the notch 330 and the portion of the connecting portion 210 located outside the card holder 300 can be the same, for example, the two portions can be cylindrical structures of equal diameter.

[0067] As described above, the snap-fit ​​portion 220 is used to snap into the positioning hole of the door sheet metal 400. The snap-fit ​​portion 220 may include a support post 221 arranged along the snap-fit ​​direction of the snap-fit ​​portion 220 and an elastic sheet 222 covering the support post 221. The support post 221 is fixedly connected to the connecting portion 210. One end of the elastic sheet 222 is connected to the end of the support post 221 away from the connecting portion 210, and the other end extends towards the end closer to the connecting portion 210 to form a free end 2221. When the elastic sheet 222 is subjected to external force, the free end 2221 can deform in a direction closer to or away from the support post 221. The number of elastic sheets 222 can be one or more. When there are multiple elastic sheets 222, the multiple elastic sheets 222 can be evenly spaced.

[0068] At least a portion of the outer contour of the snap-fit ​​part 220 is larger than the diameter of the positioning hole on the door sheet metal 400. When the snap-fit ​​part 220 is inserted into the positioning hole on the door sheet metal 400, the snap-fit ​​part 220 is aligned with the positioning hole on the door sheet metal 400, and then a certain external force is applied. The elastic piece 222 will deform to adapt to the shape and size of the positioning hole on the door sheet metal 400, so that the snap-fit ​​part 220 passes through the positioning hole on the door sheet metal 400, and the free end of the elastic piece 222 can abut against the door sheet metal 400.

[0069] It should be noted that the snap-fit ​​direction of the snap-fit ​​part 220 refers to the direction of movement of the snap-fit ​​part 220 during the process of inserting the snap-fit ​​part 220 into the positioning hole of the door sheet metal 400. The snap-fit ​​direction of the snap-fit ​​part 220 can be a direction perpendicular to the door sheet metal 400.

[0070] In a further technical solution, along the centerline direction of the support column 221 (i.e., the snapping direction of the snap-fit ​​portion 220), the cross-sectional area of ​​the middle part of the outer contour of the snap-fit ​​portion 220 can be larger than the cross-sectional area of ​​both ends. In other words, along the direction from the end of the support column 221 away from the connecting portion 210 to the connecting portion 210, the outer contour of the snap-fit ​​portion 220 first gradually expands and then gradually narrows in the middle. This structure facilitates the insertion of the snap-fit ​​portion 220 into the positioning hole of the door sheet metal 400.

[0071] Based on the aforementioned water-cutting capability, this application also provides a vehicle that includes the aforementioned water-cutting capability. Since the vehicle possesses the aforementioned water-cutting capability, the beneficial effects of the water-cutting capability on the vehicle are described above and will not be repeated here.

[0072] In a further technical solution, the water cutter can be a concealed external water cutter. The end joint angle 100 of the concealed external water cutter can be connected to the inner sheet metal or outer sheet metal of the door through a buckle 200. The connection method between the water cutter body of the concealed external water cutter and the door is existing technology and will not be described in detail here.
