Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water cutting decoration strips, and particularly relates to a water cutting assembly and a vehicle. BACKGROUND

[0002] With the development of vehicle technology, a vehicle water cutting is often provided in a vehicle as the most important sealing strip in a vehicle sealing system. The vehicle water cutting is a structure installed between a vehicle window glass and a vehicle body panel, which is tightly attached to the vehicle window glass in use to achieve the effects of waterproofing, dustproofing, shock absorption and sealing. The vehicle water cutting usually includes a water cutting sealing strip and a water cutting decoration strip. The water cutting sealing strip is installed on the vehicle body panel, and the water cutting decoration strip is installed on the water cutting sealing strip. However, the current assembly mode of the water cutting decoration strip and the water cutting sealing strip easily causes the water cutting decoration strip to be difficult to be detached from the water cutting sealing strip without damage, thereby resulting in poor maintainability of the vehicle water cutting. SUMMARY

[0003] Embodiments of the present application provide a water cutting assembly and a vehicle, which can enable the water cutting decoration strip to be detached from the water cutting sealing strip without damage and enable the vehicle water cutting to have good maintainability.

[0004] In a first aspect, the present application provides a water cutting assembly, which comprises:

[0005] an outer trim panel, the outer trim panel comprising a middle portion, a first side portion and a second side portion, the first side portion, the middle portion and the second side portion being sequentially arranged in a width direction of the outer trim panel;

[0006] a sealing strip, the sealing strip comprising an injection molding end, the injection molding end comprising a middle injection molding portion, a first injection molding portion and a second injection molding portion, the middle injection molding portion being oppositely arranged with the middle portion in a thickness direction of the water cutting assembly, the middle injection molding portion having a mounting groove, an opening of the mounting groove being located on a surface of the middle injection molding portion facing the middle portion, the first injection molding portion being connected to one end of the middle injection molding portion and oppositely arranged with the first side portion in the thickness direction of the water cutting assembly, a hardness of the first injection molding portion being less than a hardness of the middle injection molding portion, the second injection molding portion being connected to the other end of the middle injection molding portion and oppositely arranged with the second side portion in the thickness direction of the water cutting assembly, a hardness of the second injection molding portion being less than the hardness of the middle injection molding portion; and

[0007] a quick release mechanism, the quick release mechanism comprising a clamping body and a gripping structure, the clamping body being connected to the middle portion, the gripping structure being mounted in the mounting groove, when the clamping body and the gripping structure are locked, the first side portion and the first injection molding portion abut, the second side portion and the second injection molding portion abut, so that the outer trim panel and the sealing strip are fixed.

[0008] It can be understood that, since the hardness of the intermediate plastic sealing part is greater than the hardness of the first plastic sealing part and the hardness of the second plastic sealing part, the plastic used to prepare the intermediate plastic sealing part is different from the plastic used to prepare the first plastic sealing part and the second plastic sealing part. That is, the injection end can be prepared by using a double-material injection molding process, which can be composed of soft material with smaller hardness and hard material with larger hardness. The first plastic sealing part and the second plastic sealing part with smaller hardness are arranged at the two ends of the injection end, and the intermediate injection part with larger hardness is arranged in the middle region of the injection end. When the outer trim panel is connected with the injection end, the first plastic sealing part is deformed by being pressed by the first side of the outer trim panel, so as to be in direct contact with the first side of the outer trim panel and tightly fit (hereinafter referred to as zero fit of the first plastic sealing part with the first side of the outer trim panel), and the second plastic sealing part is deformed by being pressed by the second side of the outer trim panel, so as to be in direct contact with the second side of the outer trim panel and tightly fit (hereinafter referred to as zero fit of the second plastic sealing part with the second side of the outer trim panel), so as to better fix the outer trim panel and have stronger connection performance.

[0009] When the clamping body located in the middle of the outer trim panel is clamped with the gripping structure located in the intermediate plastic sealing part of the sealing strip, the outer trim panel is pulled inward (i.e. in the direction of the sealing strip) by the sealing strip. At this time, the pulling force of the sealing strip on the middle of the outer trim panel is opposite to the zero fit supporting force of the first plastic sealing part of the sealing strip on the first side of the outer trim panel and the zero fit supporting force of the second plastic sealing part of the sealing strip on the second side of the outer trim panel, so as to maintain the balance of the forces, fix the first side of the outer trim panel with the first plastic sealing part of the sealing strip, fix the second side of the outer trim panel with the second plastic sealing part of the sealing strip, and fix the middle of the outer trim panel with the intermediate plastic sealing part of the sealing strip, so as to tightly fix the outer trim panel on the sealing strip as a whole and better fix the outer trim panel.

[0010] In the related art, the two ends of the outer trim panel in the width direction are assembled with the sealing strip by using a clamping method, which causes difficulty in non-damage disassembly of the outer trim panel when the outer trim panel is disassembled from the sealing strip. In the technical solution of the present application, the hardness of the first plastic sealing part and the second plastic sealing part located at the two ends is effectively utilized, and the injection characteristics and the characteristics of the interaction of forces of the intermediate plastic sealing part located in the middle region are less than those of the intermediate plastic sealing part, so that the first plastic sealing part of the sealing strip can be in contact with the first side of the outer trim panel under the pressing force applied by the first side of the outer trim panel and the pulling force applied by the gripping structure. And the second plastic sealing part of the sealing strip can be in contact with the second side of the outer trim panel under the pressing force applied by the second side of the outer trim panel and the pulling force applied by the gripping structure.

[0011] Thus, the fixing of the two ends in the width direction of the injection-molded end to the two ends in the width direction of the outer trim panel can be achieved without using a clamping manner, the reliability is higher, and the assembly characteristics of lossless and rapid disassembly of the outer trim panel from the sealing strip and rapid installation of the outer trim panel to the sealing strip are facilitated, so that the water cutting assembly has better quick disassembly performance and maintainability.

DETAILED DESCRIPTION

[0050] For the convenience of understanding, the terms involved in the embodiments of the present application are first explained.

[0051] And / or: is only a description of the association relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B together, and the existence of B alone.

[0052] Multiple: means two or more than two.

[0053] Connection: should be understood in a broad sense, for example, A is connected with B, which can be that A is directly connected with B, or A is indirectly connected with B through intermediate medium.

[0054] The specific embodiments of the present application will be clearly described below with reference to the accompanying drawings.

[0055] Embodiments of the present application provide a water cutting assembly and a vehicle.

[0056] Please refer to Figure 1 , Figure 1 is a structural schematic diagram of a vehicle 200 provided by embodiments of the present application.

[0057] The vehicle 200 can include a window glass 210, a water cutting assembly 100 and a vehicle body panel 220. The window glass 210 can be installed at a viewing window of the vehicle body panel 220, and the water cutting assembly 100 is installed on the vehicle body panel 220 and abuts against the window glass 210 to be connected between the window glass 210 and the vehicle body panel 220. The water cutting assembly 100 can be used to seal the gap between the window glass 210 and the viewing window of the vehicle body panel 220, and also plays a role of decorating the vehicle body panel 220.

[0058] Hereinafter, for the convenience of description, the length direction of the water cutting assembly 100 is defined as the X direction, the width direction of the water cutting assembly 100 is defined as the Y direction, and the thickness direction of the water cutting assembly 100 is defined as the Z direction, and the X direction, the Y direction and the Z direction are perpendicular to each other. Among them, the length direction of the water cutting assembly 100 can be parallel or substantially parallel to the driving direction of the vehicle 200.

[0059] Please refer to Figure 2 and Figure 3 , Figure 2 is a structural schematic diagram of a water cutting assembly 100 provided by embodiments of the present application, Figure 3 is a sectional view obtained by cutting along the cutting line A-A shown in Figure 2 .

[0060] The water cutting assembly 100 can include an outer trim panel 10, a sealing strip 20, a light emitting module (not shown in the figure), and a quick release mechanism 30. The outer trim panel 10 is connected with the sealing strip 20 to form a containing space W of the water cutting assembly 100. The light emitting module is located in the containing space W of the water cutting assembly 100 and emits light outward through the outer trim panel 10, so that the water cutting assembly 100 has a light emitting function. Part of the quick release mechanism 30 is connected to the outer trim panel 10, and another part of the quick release mechanism 30 is connected to the sealing strip 20. The quick release mechanism 30 can realize quick disassembly between the sealing strip 20 and the outer trim panel 10, so that the water cutting trim panel can be disassembled from the water cutting sealing strip 20 without damage and the water cutting of the vehicle 200 has better maintainability. For example, when the light emitting module needs to be replaced or repaired, not only can the outer trim panel 10 be quickly disassembled from the sealing strip 20 without damage, but also the outer trim panel 10 can be quickly reinstalled on the sealing strip 20 after the light emitting module is replaced or repaired, and the maintainability is better.

[0061] It can be understood that, since the water cutting assembly 100 is both a sealing member and an appearance decoration member, it has higher appearance requirements. By arranging the light emitting module in the water cutting body, the water cutting assembly 100 realizes the interactive function of light emission, which not only makes the modeling of the water cutting assembly 100 more beautiful and improves the appearance performance of the water cutting assembly 100. Moreover, in the night and in the environment with dim light, the vehicle body contour can be clearly presented, so that the user has higher safety in driving on the road at night. Of course, in other embodiments, the water cutting assembly 100 can not include the light emitting module, and no strict limitation is made in this regard.

[0062] It should be noted that, Figure 2 and Figure 3 The purpose is only to schematically describe the connection relationship of the outer trim panel 10, the sealing strip 20, and the quick release mechanism 30, and not to specifically limit the connection position, specific structure, and number of each component. The structure schematically shown in the embodiments of the present application does not constitute a specific limitation on the water cutting assembly 100. In other embodiments of the present application, the water cutting assembly 100 can include more or fewer components than those shown in Figure 2 and Figure 3 some components can be combined, some components can be split, or different component arrangements. Figure 2 and Figure 3 The components shown in

[0063] Please continue to refer to Figure 2 and Figure 3The outer trim panel 10 can extend along the X direction, which is the part of the water cutting assembly 100 exposed outside the vehicle 200, i.e. the appearance part of the water cutting assembly 100. The outer trim panel 10 has high strength, scratch resistance, corrosion resistance, heat resistance, transparency, good electrical performance, etc., and the surface can be chrome plated and painted. The outer trim panel 10 can be made of a material that can transmit light. Exemplarily, the outer trim panel 10 can be in the form of a cover and made of a light-transmitting plastic material. In this arrangement, since the outer trim panel 10 is made of plastic material, the weight of the water cutting assembly 100 can be greatly reduced compared to aluminum alloy or stainless steel material.

[0064] Specifically, the outer trim panel 10 can include a middle part 11, a first side part 12 and a second side part 13. The first side part 12 can extend along the X direction and be disposed close to the window glass 210, which can be the part of the outer trim panel 10 located at the upper part. The second side part 13 can extend along the X direction and be disposed close to the body panel 220, which can be the part of the outer trim panel 10 located at the lower part. The middle part 11 is connected between the first side part 12 and the second side part 13 and is the part of the outer trim panel 10 located at the middle position. The first side part 12, the middle part 11 and the second side part 13 can be sequentially arranged in the width direction (i.e. the Y direction) of the outer trim panel 10.

[0065] The sealing strip 20 can include an extension part 21 and an injection-molded end 22. The injection-molded end 22 is connected to the extension part 21 and can be formed by placing the end of the sealing strip 20 in an injection-molding mold for injection-molding. The number of injection-molded ends 22 can be two, and the two injection-molded ends 22 form the two ends of the sealing strip 20, respectively. The structures of the two injection-molded ends 22 can be the same or different. The extension part 21 can extend along the X direction and be connected between the two injection-molded ends 22. Exemplarily, the forming method of the sealing strip 20 can be extrusion molding.

[0066] Hereinafter, the structure of the injection-molded end 22 will be described by taking one injection-molded end 22 as an example, and the description of the structure of one injection-molded end 22 below can be applied to other injection-molded ends 22 without conflict.

[0067] Please refer to Figure 4 and Figure 5 The injection-molded end 22 can include a middle injection-molded part 221, a first injection-molded part 222 and a second injection-molded part 223. The hardness of the first injection-molded part 222 can be less than that of the middle injection-molded part 221, and the hardness of the second injection-molded part 223 can be less than that of the middle injection-molded part 221. Hardness is the ability of a material to resist the indentation of a hard object on its surface.

[0068] The intermediate plastic sealing portion 221 is arranged opposite the middle portion 11 of the outer trim 10 in the Z direction. The intermediate plastic sealing portion 221 can have a mounting groove 224. An opening H of the mounting groove 224 is located on a surface of the intermediate plastic sealing portion 221 facing the middle portion 11 of the outer trim 10, and the mounting groove 224 can be recessed from the surface of the intermediate plastic sealing portion 221 facing the middle portion 11 of the outer trim 10 to the inside of the intermediate plastic sealing portion 221. The mounting groove 224 can include a bottom wall 2241 and a peripheral wall 2242. The bottom wall 2241 of the mounting groove 224 can be arranged opposite the opening H of the mounting groove 224 in the extension direction of the mounting groove 224. The peripheral wall 2242 of the mounting groove 224 can be connected between the bottom wall 2241 of the mounting groove 224 and the opening H of the mounting groove 224, and can be a wall surface surrounding the bottom wall 2241 of the mounting groove 224. For example, when the mounting groove 224 is a rectangular groove, the peripheral wall 2242 of the mounting groove 224 can be four wall surfaces connected to the bottom wall 2241 of the mounting groove 224 in sequence. The mounting groove 224 can be used to mount the partial quick release mechanism 30. For example, the material of the intermediate plastic sealing portion 221 can be TPE (Thermoplastic Elastomer).

[0069] The first plastic sealing portion 222 is connected to one end of the intermediate plastic sealing portion 221 and arranged opposite the first side portion 12 of the outer trim 10 in the Z direction. For example, the material of the first plastic sealing portion 222 can be PP-GF30, i.e., PP (polypropylene) with 30% GF (glass fiber) reinforcement.

[0070] The second plastic sealing portion 223 is connected to the other end of the intermediate plastic sealing portion 221 and arranged opposite the second side portion 13 of the outer trim 10 in the Z direction. The material of the second plastic sealing portion 223 can be the same as or different from the material of the first plastic sealing portion 222. For example, the material of the second plastic sealing portion 223 can be PP-GF30, i.e., PP (polypropylene) with 30% GF (glass fiber) reinforcement.

[0071] It can be understood that, since the hardness of the intermediate plastic sealing part 221 is greater than the hardness of the first plastic sealing part 222 and the hardness of the second plastic sealing part 223, the plastic used to prepare the intermediate plastic sealing part 221 is different from the plastic used to prepare the first plastic sealing part 222 and the second plastic sealing part 223. That is, the injection end 22 can be prepared by using a double-material injection molding process, which can be composed of soft material with smaller hardness and hard material with greater hardness. The first plastic sealing part 222 and the second plastic sealing part 223 with smaller hardness are arranged at the two end portions of the injection end 22, and the intermediate injection part with greater hardness is arranged in the middle region of the injection end 22. When the outer trim panel 10 is connected with the injection end 22, the first plastic sealing part 222 can be deformed by pressing the first side portion 12 of the outer trim panel 10 to directly contact and tightly fit with the first side portion 12 of the outer trim panel 10 (hereinafter referred to as zero fit of the first plastic sealing part 222 and the first side portion 12 of the outer trim panel 10), and the second plastic sealing part 223 can be deformed by pressing the second side portion 13 of the outer trim panel 10 to directly contact and tightly fit with the second side portion 13 of the outer trim panel 10 (hereinafter referred to as zero fit of the second plastic sealing part 223 and the second side portion 13 of the outer trim panel 10), so as to better fix the outer trim panel 10 and have stronger connection performance.

[0072] Please refer to Figure 4 and Figure 2 , Figure 5 is Figure 2 a schematic view of a state of the quick release mechanism 30 of the water cutting assembly 100 shown in Figure 4 is Figure 5 a schematic view of another state of the quick release mechanism 30 of the water cutting assembly 100. The quick release mechanism 30 can include a clamping body 31 and a clamping structure 32.

[0073] It should be noted that Figure 4 and Figure 5 only aim to schematically describe the connection relationship between the clamping body 31 and the clamping structure 32, and are not specific limitations on the connection positions, specific structures and quantities of the components. The structures schematically shown in the embodiments of the present application do not constitute specific limitations on the quick release mechanism 30. In other embodiments of the present application, the quick release mechanism 30 can include more or fewer components than Figure 4 and Figure 5 shown, or combine certain components, or split certain components, or different component arrangements. Figure 4 and Figure 5 shown can be implemented in hardware, software or a combination of software and hardware.

[0074] The clamping body 31 can be connected to the middle portion 11 of the outer cover plate 10 and extend along the X direction, and is used to clamp with the clamping structure 32. The clamping body 31 can include a connecting portion 311 and a clamping portion 312. One end of the connecting portion 311 is connected to the middle portion 11 of the outer cover plate 10, and the other end of the connecting portion 311 extends away from the middle portion 11 of the outer cover plate 10. The clamping portion 312 is connected to the end of the connecting portion 311 away from the outer cover plate 10. In the height direction (i.e. the Z direction) of the clamping body 31, the cross-sectional width of the end of the clamping portion 312 connected to the connecting portion 311 is greater than the cross-sectional width of the end of the clamping portion 312 away from the connecting portion 311. Exemplarily, the shape of the clamping portion 312 can be a truncated cone shape.

[0075] Of course, in other embodiments, the shape of the clamping body 31 can also be other shapes such as a columnar shape, a hemispherical shape, etc. The embodiments of the present application do not strictly set the shape of the clamping body 31, the extension length of the clamping body 31, the height of the clamping body 31, the width of the clamping body 31, etc. as long as the clamping body 31 can be clamped with the clamping structure 32.

[0076] The clamping structure 32 can be installed in the installation groove 224 of the middle sealing portion 221. The clamping structure 32 can be locked with the clamping body 31 to fix the outer cover plate 10 and the sealing strip 20. The clamping structure 32 can also be unlocked with the clamping body 31 to separate the outer cover plate 10 and the sealing strip 20. When the clamping body 31 is locked with the clamping structure 32, the first side portion 12 of the outer cover plate 10 abuts against the first sealing portion 222 of the sealing strip 20, and the second side portion 13 of the outer cover plate 10 abuts against the second sealing portion 223 of the sealing strip 20, so as to fix the outer cover plate 10 and the sealing strip 20. When the clamping body 31 is unlocked with the clamping structure 32, the first side portion 12 of the outer cover plate 10 is separated from the first sealing portion 222 of the sealing strip 20, and the second side portion 13 of the outer cover plate 10 is separated from the second sealing portion 223 of the sealing strip 20, so as to separate the outer cover plate 10 and the sealing strip 20.

[0077] It can be understood that when the clamping body 31 located at the middle part 11 of the outer trim plate 10 is clamped with the clamping structure 32 located at the intermediate plastic sealing part 221 of the sealing strip 20, the outer trim plate 10 is pulled inward (i.e. to the direction of the sealing strip 20) by the sealing strip 20. At this time, the pulling force of the sealing strip 20 on the middle part 11 of the outer trim plate 10 is opposite to the zero-tape supporting force applied by the first plastic sealing part 222 of the sealing strip 20 to the first side part 12 of the outer trim plate 10 and the zero-tape supporting force applied by the second plastic sealing part 223 of the sealing strip 20 to the second side part 13 of the outer trim plate 10, thereby maintaining the balance of forces, fixing the first side part 12 of the outer trim plate 10 and the first plastic sealing part 222 of the sealing strip 20, fixing the second side part 13 of the outer trim plate 10 and the second plastic sealing part 223 of the sealing strip 20, and fixing the middle part 11 of the outer trim plate 10 and the intermediate plastic sealing part 221 of the sealing strip 20, thereby tightly fastening the entire outer trim plate 10 on the sealing strip 20 and playing a good role in fixing the outer trim plate 10.

[0078] In the related art, the two ends of the outer trim plate in the width direction are assembled with the sealing strip in a clamping manner, which causes difficulty in non-damage disassembly of the assembly pain point of the outer trim plate. In the technical solution of the present application, the hardness of the first plastic sealing part 222 and the second plastic sealing part 223 located at the two ends is effectively utilized, which is less than the injection molding characteristics and the interaction characteristics of the force of the intermediate plastic sealing part 221 located at the middle region, so that the first plastic sealing part 222 of the sealing strip 20 can be in contact with the first side part 12 of the outer trim plate 10 under the action of the pressing force applied by the first side part 12 of the outer trim plate 10 and the tightening force applied by the clamping structure 32. And the second plastic sealing part 223 of the sealing strip 20 can be in contact with the second side part 13 of the outer trim plate 10 under the action of the pressing force applied by the second side part 13 of the outer trim plate 10 and the tightening force applied by the clamping structure 32.

[0079] Therefore, without using a clamping method at the two ends of the injection molding end 22 in the width direction, the two ends of the injection molding end 22 in the width direction and the two ends of the outer trim plate 10 in the width direction can be fixed, which has high reliability and is conducive to realizing non-damage and rapid disassembly of the outer trim plate 10 from the sealing strip 20 and rapid installation of the outer trim plate 10 on the sealing strip 20, so that the water cutting assembly 100 has good quick disassembly performance and maintainability.

[0080] For example, when the light emitting module located in the accommodating space W formed by the sealing strip 20 and the outer trim plate 10 is damaged and needs to be replaced or repaired, the outer trim plate 10 can be quickly and non-damage disassembled from the sealing strip 20 for replacement or repair of the light emitting module. After the replacement or repair of the light emitting module, the outer trim plate 10 can be quickly installed again, so that the light emitting module has good maintainability.

[0081] In the embodiments of the present application, the second side portion 13 of the outer trim panel 10 completely covers the second plastic sealing portion 223 of the sealing strip 20. That is, the second side portion 13 of the outer trim panel 10 completely covers the second plastic sealing portion 223 of the sealing strip 20, and the projection of the second side portion 13 of the outer trim panel 10 on the vehicle body panel 220 can completely cover the projection of the second plastic sealing portion 223 of the sealing strip 20 on the vehicle body panel 220.

[0082] It can be understood that, since the second plastic sealing portion 223 of the sealing strip 20 does not need to be formed into a barb structure to be clamped with the outer trim panel 10, the second plastic sealing portion 223 of the sealing strip 20 can be arranged closer to the vehicle body panel 220. In this arrangement, the second plastic sealing portion 223 of the sealing strip 20 is not exposed to the outside of the outer trim panel 10, effectively avoiding the problem that the second plastic sealing portion 223 of the sealing strip 20 is visible from the outside, and is conducive to improving the overall appearance of the water cutting assembly 100.

[0083] Please refer to Figure 4 and Figure 5 The quick release mechanism 30 can include a locked state and an unlocked state. When the quick release mechanism 30 is in the locked state, part of the clamping body 31 is limited in the clamping structure 32, and the outer trim panel 10 is fixedly connected with the sealing strip 20. When the quick release mechanism 30 is in the unlocked state, the clamping body 31 is separated from the clamping structure 32, and the outer trim panel 10 is arranged separately from the sealing strip 20. It can be understood that, by switching the quick release mechanism 30 between the locked state and the unlocked state, the outer trim panel 10 can be assembled to the sealing strip 20 and detached from the sealing strip 20, so as to maintain the assembled state of the outer trim panel 10 and the sealing strip 20 or the separated state of the outer trim panel 10 and the sealing strip 20.

[0084] The clamping structure 32 can be elastically connected with the bottom wall 2241 of the mounting groove 224. The clamping structure 32 can move relative to the sealing strip 20 along the extension direction of the mounting groove 224 to approach the bottom wall 2241 of the mounting groove 224, and can also move relative to the sealing strip 20 along the extension direction of the mounting groove 224 to move away from the bottom wall 2241 of the mounting groove 224. Wherein, the elastic connection of the clamping structure 32 with the bottom wall 2241 of the mounting groove 224 means that the clamping structure 32 can approach the bottom wall 2241 of the mounting groove 224 after being pressed, and can move away from the bottom wall 2241 of the mounting groove 224 after the pressure is removed.

[0085] In a possible implementation, the quick release mechanism 30 can further include a first elastic member 33. One end of the first elastic member 33 is connected with the bottom wall 2241 of the mounting groove 224, and the other end of the first elastic member 33 is connected with the clamping structure 32. The first elastic member 33 can be any structural member with good elastic deformation performance, which can have a certain compression and elongation stroke to compress and produce elastic deformation after being compressed, and return to the original position after the pressure is removed. For example, the first elastic member 33 can be a spring.

[0086] Further, in the embodiment, the clamping structure 32 can have a positioning groove 321. The positioning groove 321 can extend along the length direction of the clamping structure 32, and the opening of the positioning groove 321 is located on the surface of the clamping structure 32 facing the bottom wall 2241 of the mounting groove 224. The bottom wall of the positioning groove 321 is oppositely arranged with the opening of the positioning groove 321 along the extension direction of the positioning groove 321. One end of the first elastic member 33 can be connected with the bottom wall 2241 of the mounting groove 224, and the other end of the first elastic member 33 can be connected with the bottom wall of the positioning groove 321. In this arrangement, part of the first elastic member 33 is located inside the clamping structure 32, thereby further enhancing the connection stability and reliability of the first elastic member 33 and the clamping structure 32.

[0087] Please continue to refer to Figure 4 and Figure 5 In the embodiment, the clamping structure 32 can include an elastic clamping jaw 322, a clamping body 323, and a swing arm 324. The elastic clamping jaw 322 can achieve locking and unlocking of the clamping structure 32 and the clamping body 31. The clamping body 323 is fixedly connected with the elastic clamping jaw 322, and can drive the elastic clamping jaw 322 to move together relative to the sealing strip 20, and move close to or away from the bottom wall 2241 of the mounting groove 224. The swing arm 324 is rotationally connected with the clamping body 323, and can rotate relative to the clamping body 323 about the rotation center of the swing arm 324.

[0088] The elastic clamping jaw 322 can be a structural member with good elastic deformation performance. The elastic clamping jaw 322 can be folded to form a containing cavity T after being compressed, and the containing cavity T is used to contain and limit the clamping body 31. The elastic clamping jaw 322 can also be opened after the pressure is removed. Specifically, as shown in Figure 4 When the clamping structure 32 and the clamping body 31 are assembled and locked, the quick release mechanism 30 is in a locked state, and the elastic clamping jaw 322 is in a folded state. At this time, at least part of the elastic clamping jaw 322 is located in the mounting groove 224, and is folded to form the containing cavity T, so as to limit the clamping body 31 in the containing cavity T. For example, the containing cavity T can be a V-shaped cavity. Of course, in other embodiments, the shape of the containing cavity T can also be other shapes such as a semispherical shape, a rectangular shape, etc., and the embodiments of the present application do not make strict limitations on this.

[0089] It can be understood that, in the assembling process of the outer decorative plate 10 and the sealing strip 20, the clamping body 31 connected to the outer decorative plate 10 is pressed to follow the elastic clamping jaw 322 installed into the mounting groove 224 to move to the direction of the bottom wall 2241 of the mounting groove 224. In the process of the elastic clamping jaw 322 being pressed, the elastic clamping jaw 322 is gradually folded under the pressure of the circumferential side wall 2242 of the mounting groove 224, so as to wrap the clamping body 31 connected to the outer decorative plate 10, and the clamping body 31 connected to the outer decorative plate 10 is limited in the accommodating cavity T formed by the elastic clamping jaw 322.

[0090] As shown in Figure 5 , when the clamping structure 32 and the clamping body 31 are not assembled and are unlocked, the quick release mechanism 30 is in the unlocked state, and the elastic clamping jaw 322 is in the unfolded state. At this time, at least part of the elastic clamping jaw 322 is located outside the mounting groove 224 and is unfolded to separate from the clamping body 31.

[0091] It can be understood that, when the outer decorative plate 10 and the sealing strip 20 are not assembled, the clamping body 31 connected to the outer decorative plate 10 has been separated from the elastic clamping jaw 322, and at least part of the elastic clamping jaw 322 is located outside the mounting groove 224. Since the elastic clamping jaw 322 is no longer pressed by the circumferential side wall 2242 of the mounting groove 224 or is less pressed by the circumferential side wall 2242 of the mounting groove 224, the elastic clamping jaw 322 is elastically reset to be unfolded to block the opening H of the mounting groove 224.

[0092] Based on the above description, it can be understood that, by folding and unfolding of the elastic clamping jaw 322, the clamping body 31 connected to the outer decorative plate 10 can be limited in the accommodating cavity T of the elastic clamping jaw 322 or separated from the elastic clamping jaw 322, and the two states of locking and unlocking are reliable.

[0093] In a possible implementation, as shown in Figure 4 and Figure 5 , the elastic clamping jaw 322 can include a bottom portion 3221 and a gripping portion 3222. The bottom portion 3221 can be connected with the clamping body 323. The gripping portion 3222 can be connected to the outer edge of the bottom portion 3221. The gripping portion 3222 can be rotated relative to the bottom portion 3221 to be folded, so that the elastic clamping jaw 322 is in the folded state. The gripping portion 3222 can also be rotated relative to the bottom portion 3221 to be unfolded, so that the elastic clamping jaw 322 is in the unfolded state.

[0094] Please continue to refer to Figure 4 and Figure 5In the embodiment of the present application, the clamping body 323 is elastically connected to the bottom wall 2241 of the mounting groove 224 through the first elastic member 33, so that the clamping body 323 can move along the extension direction of the mounting groove 224 to approach the bottom wall 2241 of the mounting groove 224, or move along the extension direction of the mounting groove 224 to move away from the bottom wall 2241 of the mounting groove 224. The clamping body 323 is also fixedly connected to the elastic clamping jaw 322, so as to drive the elastic clamping jaw 322 to move along the extension direction of the mounting groove 224 to approach the bottom wall 2241 of the mounting groove 224, or drive the elastic clamping jaw 322 to move along the extension direction of the mounting groove 224 to move away from the bottom wall 2241 of the mounting groove 224 relative to the sealing strip 20.

[0095] In a possible implementation manner, as shown in Figure 4 and Figure 5 The clamping body 323 can have a stepped structure 3231. The stepped structure 3231 can be located on the outer surface of the clamping body 323. For example, the clamping body 323 can include a first portion 3232 and a second portion 3233. The first portion 3232 is connected between the elastic clamping jaw 322 and the second portion 3233, and the outer diameter of the first portion 3232 is smaller than the outer diameter of the second portion 3233, so as to form the stepped structure 3231 at the connection between the first portion 3232 and the second portion 3233.

[0096] In the embodiment, the quick release mechanism 30 can further include a limiting structure 34. The limiting structure 34 is located in the mounting groove 224 and is fixedly connected to the peripheral side wall 2242 of the mounting groove 224. The limiting structure 34 can be used to be clamped with the stepped structure 3231, so as to limit the clamping body 323 from being separated from the mounting groove 224 through the opening H of the mounting groove 224. For example, the number of the limiting structure 34 can be two, and the two limiting structures 34 are respectively located on both sides of the clamping body 323 in the width direction.

[0097] It can be understood that, since the first elastic member 33 is elastically connected between the clamping body 323 and the bottom wall 2241 of the mounting groove 224, after the pressure applied to the first elastic member 33 is removed, the first elastic member 33 will rebound and reset, and drive the clamping body 323 to move away from the bottom wall 2241 of the mounting groove 224. By arranging the limiting structure 34 and clamping the limiting structure 34 with the stepped structure 3231, the movement stroke of the clamping body 323 relative to the bottom wall 2241 of the mounting groove 224 can be effectively limited, and the clamping body 323 can be prevented from being continuously pushed upward by the first elastic member 33, so as to effectively avoid the problem that the quick release mechanism 30 is disabled due to the disengagement of the clamping structure 32 from the mounting groove 224, and the clamping structure 32 has good installation stability and reliability.

[0098] Please continue to referFigure 5 and Figure 5 In some embodiments, the swing arm 324 can include a swing arm body 3241, a first shaft 3242, and a second shaft 3243. The swing arm body 3241 can include a first end 3244 and a second end 3245, which are oppositely arranged along the length direction of the swing arm body 3241. One end of the first shaft 3242 is connected to the first end 3244 of the swing arm body 3241, and the other end of the first shaft 3242 is connected to the clamping body 323. The swing arm body 3241 can be rotationally connected to the clamping body 323 through the first shaft 3242, i.e., the swing arm body 3241 can rotate relative to the clamping body 323 about the rotation center of the first shaft 3242, wherein the rotation center of the first shaft 3242 is the central axis of the first shaft 3242. One end of the second shaft 3243 is connected to the second end 3245 of the swing arm body 3241, and the other end of the second shaft 3243 extends away from the swing arm body 3241. The second shaft 3243 and the first shaft 3242 are respectively located on opposite sides of the swing arm body 3241 in the thickness direction.

[0099] In some embodiments, as shown in FIGS. 1A and 1B, the quick release mechanism 30 can further include a first stroke guide 35 and a second stroke guide 36. The first stroke guide 35 and the second stroke guide 36 are both mounted in the mounting slot 224. The first stroke guide 35 and the second stroke guide 36 are oppositely and spacedly arranged along the extension direction of the mounting slot 224, and the first stroke guide 35 is closer to the opening H of the mounting slot 224 than the second stroke guide 36. The first stroke guide 35 and the second stroke guide 36 can both be used to limit the movement of the swing arm 324, specifically, to limit the movement of the second shaft 3243 of the swing arm 324. In some embodiments, the first stroke guide 35 can be a first guide rail, and the second stroke guide 36 can be a second guide rail. Figure 4 and Figure 5 The trajectory outside the first stroke guide 35 in FIG. 1A is the movement trajectory Q of the second shaft 3243 of the swing arm 324. Figure 4

[0100] The first stroke guide 35 can be located in the mounting slot 224 and fixedly connected to the peripheral side wall 2242, and spacedly arranged with the clamping body 323 in the thickness direction of the waterjet assembly 100. In other words, in the mounting slot 224, one of the first stroke guide 35 and the clamping body 323 is located in the upper layer, and the other of the first stroke guide 35 and the clamping body 323 is located in the lower layer. The first stroke guide 35 can be arranged in different layers from the clamping body 323 to avoid affecting the movement of the swing arm 324. The second shaft 3243 of the swing arm 324 can move along the outer contour of the first stroke guide 35 and be used to be clamped with the first stroke guide 35.

[0101] ​It can be understood that, since the clamping body 323 and the bottom wall 2241 of the mounting groove 224 can be elastically connected by the first elastic member 33, the clamping body 323 can reciprocate along the extension direction of the mounting groove 224 in the mounting groove 224 due to the elastic force of the first elastic member 33. Since the first stroke guide 35 is arranged on the moving path of the swing arm 324, the swing arm body 3241 will rotate relative to the clamping body 323 through the first shaft 3242, and the second shaft 3243 will also rotate relative to the clamping body 323, so that the second shaft 3243 moves along the outer contour of the first stroke guide 35 during the rotation relative to the clamping body 323, when the clamping body 323 reciprocates along the extension direction of the mounting groove 224 in the mounting groove 224.

[0102] When the second shaft 3243 of the swing arm 324 moves to be clamped by the first stroke guide 35, the clamping body 323 is fixed in position and cannot continue to move towards the bottom wall 2241 of the mounting groove 224. At this time, the clamping structure 32 is locked with the clamping body 31, the quick release mechanism 30 is in a locked state, and the outer trim panel 10 and the sealing strip 20 are fixedly connected. When the second shaft 3243 of the swing arm 324 continues to move and is separated from the first stroke guide 35, the clamping body 323 moves away from the bottom wall 2241 of the mounting groove 224 to restore the original position. At this time, the clamping structure 32 is separated from the clamping body 31, the quick release mechanism 30 is in an unlocked state, and the outer trim panel 10 and the sealing strip 20 can be separated. During the switching of the quick release mechanism 30 from the unlocked state to the locked state and then to the unlocked state, the second shaft 3243 of the swing arm 324 can complete a circle along the outer contour of the first stroke guide 35. Exemplarily, the movement path of the second shaft 3243 of the swing arm 324 can be the movement path shown in the figure. Figure 5

[0103] Based on the above description, it can be understood that the first stroke guide 35 can be used to clamp the swing arm 324 to make the quick release mechanism 30 in a locked state. Alternatively, the first stroke guide 35 can be used to separate the swing arm 324 to make the quick release mechanism 30 in an unlocked state.

[0104] Please continue to refer to Figure 3 and Figure 4 , the first stroke guide 35 can be arranged obliquely relative to the bottom wall 2241 of the mounting groove 224. The first stroke guide 35 can include a recess 351, a first protrusion 352, a second protrusion 353, and a third protrusion 354. The recess 351, the first protrusion 352, and the second protrusion 353 are all located at one end of the first stroke guide 35 towards the second stroke guide 36. The recess 351 is connected between the first protrusion 352 and the second protrusion 353. The third protrusion 354 is located at the other end of the first stroke guide 35 away from the second stroke guide 36.​

[0105] The second stroke guide 36 can be located in the mounting groove 224 and fixedly connected to the peripheral wall 2242, and the second stroke guide 36 can be vertically arranged relative to the bottom wall 2241 of the mounting groove 224. The gap between the second stroke guide 36 and the first stroke guide 35 is used to limit the movement path of the second shaft 3243 of the swing arm 324. The second stroke guide 36 can include a fourth protrusion 361, and part of the fourth protrusion 361 is located in the recess 351 of the first stroke guide 35 and has a gap with the recess 351 of the first stroke guide 35.

[0106] The second shaft 3243 of the swing arm 324 can move along the outer contour of the first stroke guide 35 in the order of the initial position, the first protrusion 352, the recess 351, the second protrusion 353, the third protrusion 354, and the initial position. Among them, the initial position is the maximum distance between the first shaft 3242 of the swing arm 324 and the bottom wall 2241 of the mounting groove 224 in the extension direction of the mounting groove 224, that is, the position where the elastic clamping jaw 322 is open, and the natural state of the swing arm 324.

[0107] The movement path of the second shaft 3243 of the swing arm 324 and the setting of various characteristic parameters of the first stroke guide 35 and the second stroke guide 36 will be described below through two different embodiments.

[0108] In one possible embodiment, as shown in Figure 5 and Figure 5 The extension direction of the quick release mechanism 30 is arranged in parallel with the direction of gravity G. That is, the outer trim panel 10 can be installed vertically with the sealing strip 20.

[0109] In this embodiment, before the outer trim panel 10 is installed to the sealing strip 20, the second shaft 3243 of the swing arm 324 is initially located at position 1, wherein position 1 is the initial position of the second shaft 3243 of the swing arm 324. When the second shaft 3243 of the swing arm 324 is at position 1, the elastic clamping jaw 322 is in an open state, and the extension direction of the swing arm 324 can be arranged vertically to the bottom wall 2241 of the mounting groove 224.

[0110] And the process of assembling the outer trim panel 10 and the sealing strip 20 is as follows:

[0111] First, press the outer trim panel 10, so that the clamping body 31 connected to the outer trim panel 10 is driven to press the gripping structure 32 downward, thereby driving the gripping structure 32 to move to the bottom wall 2241 of the mounting groove 224, so that the second shaft 3243 of the swing arm 324 is moved to position 2 under the action of the first stroke guide 35. When the second shaft 3243 of the swing arm 324 is at position 2, the extension direction of the swing arm 324 can be arranged obliquely to the bottom wall 2241 of the mounting groove 224.

[0112] Secondly, continue to press the outer trim plate 10, and under the action of gravity, the second shaft 3243 of the swing arm 324 moves to position 3.

[0113] Then, release the outer trim plate 10, and due to the elastic force of the first elastic member 33, the clamping body 323 moves away from the bottom wall 2241 of the mounting groove 224 along the extension direction of the mounting groove 224, and drives the second shaft 3243 of the swing arm 324 to move upward by a stroke and to position 4. When the second shaft 3243 of the swing arm 324 is at position 4, the second shaft 3243 of the swing arm 324 can be clamped with the recess 351 of the first stroke guide 35, so that the quick release mechanism 30 is in a locked state, and the outer trim plate 10 is fixedly connected with the sealing strip 20.

[0114] The process of disassembling the outer trim plate 10 and the sealing strip 20 is as follows:

[0115] Firstly, press the outer trim plate 10, so that the clamping body 31 connected to the outer trim plate 10 is driven to press downward the gripping structure 32, and then drives the gripping structure 32 to move to the bottom wall 2241 of the mounting groove 224, so that the second shaft 3243 of the swing arm 324 moves from position 4 to position 5 under the action of the first stroke guide 35, so that the quick release mechanism switches from the locked state to the unlocked state.

[0116] Secondly, release the outer trim plate 10, so that the pressing force applied to the outer trim plate 10 disappears. Under the action of the first elastic member 33, the clamping body 323 moves away from the bottom wall 2241 of the mounting groove 224 along the extension direction of the mounting groove 224, and drives the second shaft 3243 of the swing arm 324 to move upward by a stroke and to position 6.

[0117] Finally, due to the action of gravity, the second shaft 3243 of the swing arm 324 returns to position 1.

[0118] Please refer to Figure 6 , Figure 6 and Figure 2 , the characteristic parameters of the quick release mechanism 30 involved in the movement of the second shaft 3243 of the swing arm 324 according to the movement trajectory Q shown in Figure 7 will be described as follows.

[0119] The first distance L1 is defined as the maximum distance that the clamping body 323 moves relative to the bottom wall 2241 of the mounting groove 224 in the extension direction of the mounting groove 224. The second distance (L2+L3+L4) is defined as the distance that the second shaft 3243 of the swing arm 324 moves along the outer contour of the first stroke guide 35 from the initial position to the outside of the first protrusion 352 (i.e. the distance that the second shaft 3243 of the swing arm 324 moves along the outer contour of the first stroke guide 35 from position 1 to position 3). The third distance L5 is defined as the distance between the second protrusion 353 and the third protrusion 354 in the extension direction of the mounting groove 224. The fourth distance L6 is defined as the distance between the second side 13 of the outer trim panel 10 and the body panel 220 in the assembling direction of the outer trim panel 10 and the sealing strip 20.

[0120] To ensure that the second shaft 3243 of the swing arm 324 can move from position 1 to position 3, the first distance L1 and the second distance (L2+L3+L4) should satisfy the relationship L1≥L2+L3+L4. To ensure that the second shaft 3243 of the swing arm 324 can move from position 3 to position 4, the inflection point P2 of the fourth protrusion 361 should be located to the right of the inflection point P1 of the first protrusion 352. To ensure that the second shaft 3243 of the swing arm 324 can move from position 4 to position 5, the inflection point P3 of the recess 351 should be located to the right of the inflection point P2 of the fourth protrusion 361, and the inflection point P4 of the second protrusion 353 should be located to the right of the inflection point P3 of the recess 351. Even if the inflection point P2 of the fourth protrusion 361 is located between the inflection point P1 of the first protrusion 352 and the inflection point P3 of the recess 351, and the inflection point P3 of the recess 351 is located between the inflection point P2 of the fourth protrusion 361 and the inflection point P4 of the second protrusion 353. To ensure that the second shaft 3243 of the swing arm 324 can move from position 5 to position 6, the first distance L1 and the third distance L5 should satisfy the relationship L1≥L5, and the inflection point P1 of the first protrusion 352, the inflection point P3 of the recess 351 and the inflection point P4 of the second protrusion 353 should be located on one side of the central axis of the swing arm 324 in the initial position, and the inflection point P5 of the third protrusion 354 should be located on the other side of the central axis of the swing arm 324 in the initial position.

[0121] In addition, since the second side 13 of the outer trim panel 10 needs to have a certain stroke in the assembling direction, to avoid the second side 13 of the outer trim panel 10 from colliding with the body panel 220 located below the second side 13 of the outer trim panel 10, the fourth distance L6 and the first distance L1 should satisfy the relationship L6≥L1.

[0122] In another possible implementation, please refer to Figure 7 , Figure 2 is Figure 7Another state diagram of the quick release mechanism 30 of the water cutting assembly 100 is shown. The same as the previous embodiment, the different is that the extending direction of the quick release mechanism 30 is not the same as the direction of gravity G. That is, the outer cover plate 10 can be installed on the sealing strip 20 in an inclined manner.

[0123] In this embodiment, the quick release mechanism 30 can further include a second elastic member 37. One end of the second elastic member 37 is connected with the swing arm 324, and the other end of the second elastic member 37 is connected with the outer edge of the clamping body 323. The second elastic member 37 can be any structure with good elastic deformation performance, which can have a certain compression and elongation stroke to compress and produce elastic deformation after being pressed, and return to the original position after the pressure is removed. Exemplarily, the second elastic member 37 can be a spring.

[0124] In this arrangement, the second elastic member 37 can be in a natural state (non-compressed or stretched state) to ensure that the extending direction of the swing arm 324 is parallel to the extending direction of the quick release mechanism 30 (i.e., the installation direction of the quick release mechanism 30).

[0125] Please refer to Figure 7 , Figure 8 is along Figure 8 a cross-sectional view obtained by cutting along the cutting line B-B.

[0126] In the embodiment of the present application, the hardness of the two ends of the extension part 21 along the width direction (i.e., the upper end of the extension part 21 and the lower end of the extension part 21) can be less than the hardness of other parts of the extension part 21 (i.e., the middle part 11 of the extension part 21). Figure 2 ​ Exemplarily, the material of the low-hardness part of the upper end of the extension part 21 and the lower end of the extension part 21 can be thermoplastic ethylene-propylene rubber (EPDM / PP).

[0127] It can be understood that the fixation of the two ends of the water cutting assembly 100 along the length direction can be achieved by the quick release mechanism 30, that is, the outer cover plate 10 is clamped on the injection molded end 22 of the sealing strip 20 at the two ends of the sealing strip 20 by the quick release mechanism 30. The remaining positions of the water cutting assembly 100 can give the outer cover plate 10 an outward thrust force through the zero-sticking position C1 between the first side part 12 of the outer cover plate 10 at the upper end of the water cutting assembly 100 and the extension part 21 of the sealing strip 20, the zero-sticking position C2 between the middle part 11 of the outer cover plate 10 at the middle part 11 of the water cutting assembly 100 and the extension part 21 of the sealing strip 20, and the zero-sticking position C3 between the second side part 13 of the outer cover plate 10 at the lower end of the water cutting assembly 100 and the extension part 21 of the sealing strip 20, to ensure that the outer cover plate 10 does not shake after being installed on the sealing strip 20.

[0128] ​The low-hardness part of the lower end of the extension part 21 interferes with the body panel 220, and the outer trim panel 10 has a gap R with the low-hardness part of the lower end of the extension part 21, which provides a deformation space for the low-hardness part of the lower end of the extension part 21, so that the low-hardness part of the lower end of the extension part 21 can be filled after the water cutting assembly 100 is assembled to avoid noise or the outer trim panel 10 is lifted by the low-hardness part of the lower end of the extension part 21 without a deformation space.

[0129] In one possible implementation, referring to ​ , ​ is another cross-sectional view obtained by cutting along the cutting line B-B shown in the drawing. ​

[0130] The extension part 21 can have a clamping groove 211. The clamping groove 211 extends along the X direction and is used to clamp the clamping body 31 connected to the outer trim panel 10 to increase the firmness of the outer trim panel 10 mounted on the sealing strip 20. At the same time, since the disassembly process of the outer trim panel 10 in the embodiment of the present application is to press the two ends of the water cutting assembly 100 first, disassemble the outer trim panel 10 at the two ends of the water cutting assembly 100, and then pull the outer trim panel 10 out of the sealing strip 20. Therefore, since the structure of the clamping groove 211 and the clamping body 31 is small, it will not affect the smoothness and convenience of disassembly, and the reliability is better.

[0131] The above describes the embodiments of the present application in detail, and the principles and implementation manners of the present application are described by applying specific examples. The above description of the embodiments is only used to help understand the method of the present application and its core idea; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range will be changed, and the above description should not be understood as a limitation of the present application.​
