Water jet assembly and vehicle

[0001] Related applications

[0002] This application claims priority to the Chinese invention patent with patent application number 202311153971.5, application date September 8, 2023, and invention name “Water-cut assembly and vehicle”, and patent application number 202322434965.9, application date September 8, 2023, and invention name “Water-cut assembly and vehicle”. Technical Field

[0003] The present invention relates to the technical field of automobile water-cut decorative strips, and in particular to a water-cut assembly and a vehicle thereof. Background Art

[0004] With the rapid development of the automotive industry, people are increasingly focusing on safe driving environments, with a heightened focus on detail and demand. Furthermore, industrial competition and development are driving manufacturers to pursue higher standards for controlling production time and improving efficiency. In the automotive parts production process, simple installation, reliable assembly, and high production efficiency are the consistent goals of designers and manufacturers.

[0005] Currently, most cars primarily utilize stainless steel or aluminum alloy water-cut decorative strips to enhance the car's body lines. Water-cut decorative strips, also known as window trim strips, adhere closely to the window lift glass, blocking rainwater intrusion and providing leak prevention, sound insulation, dustproofing, vibration reduction, and sealing. They are among the most important sealing strips in the automotive sealing system. Because the window sill seal is exposed outside the window, it serves as both a seal and a decorative element, thus demanding high aesthetic standards.

[0006] Furthermore, to enhance the overall sense of luxury of a car, automotive water-repellent must not only adhere closely to the window lifts during use, blocking rainwater intrusion and achieving leak-proofing, sound insulation, dustproofing, shock absorption, and sealing, but also enable simple interactive functions such as luminescence. For example, new energy vehicles and some mid-to-high-end models are increasingly incorporating luminous elements, giving the car a more technological feel. They also clearly display the car's contours at night and in dimly lit environments, enhancing road safety.

[0007] Existing luminous water-jet systems typically require a translucent outer shield for the light guide strip. This outer shield is typically a semi-translucent plastic product formed by extrusion or injection molding. The applicant discovered that during the actual productization process, the luminous water-jet system, installed between the window glass and the door panel, had limited installation space. This, coupled with the complex design of the outer shield and other structural elements, led to drawbacks such as difficulty in mold processing and poor mass production.

[0008] Summary of the Invention

[0009] In response to the defects of the existing technology, an embodiment of the present invention provides a water-jet assembly and a vehicle thereof, which can simplify the structure of the mold, improve production efficiency, and greatly enhance the mass production of the product.

[0010] The specific technical solutions of the embodiments of the present invention are:

[0011] A water-cut assembly is used to be installed between a vehicle window glass and a door panel sheet metal. The water-cut assembly includes: a water-cut body and a seal; the seal extends longitudinally along a first direction, the seal has an inner surface facing the door panel sheet metal and an outer surface away from the door panel sheet metal, and a positioning portion is provided on the outer surface; the water-cut body extends longitudinally along the first direction as a whole, and a connecting mechanism that is connected to the positioning portion is provided on the water-cut body, and the connecting mechanism is arranged at intervals along the first direction.

[0012] The present invention provides a vehicle, comprising the water jet assembly described above.

[0013] The beneficial effects of the present invention are:

[0014] The water-cut assembly provided in the embodiment of the present application solves the problems of the existing luminous water-cut structure mold, such as the large number of molding mechanisms, difficulty in processing, and poor mass production, by improving the structure of the water-cut body (exterior decorative panel and back cover). It can simplify the structure of the mold, greatly improve the mass production of the product, and realize the universal arrangement of the optoelectronic module in the space of the plastic water-cut assembly while maintaining good optoelectronic performance.

[0015] In addition, the luminous water-cut assembly provided in the embodiment of the present application changes the fixing process between the outer trim panel and the back cover from pasting and gluing to a structural fixed installation. Specifically, by fixing the outer trim panel and the back cover with a welding structure (especially welding with ultrasonic welding technology), it overcomes a series of disadvantages brought about by the existing pasting and gluing methods, and can solve various technical problems caused by the double-sided tape / PU glue fixing method between the outer trim panel and the back cover in the prior art.

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0034] Water-cut photoelectric modules on automotive door exteriors are automotive exterior components that meet both optoelectronic functional and aesthetic requirements. Installed on the outer door panel, these modules provide a seal between the door and window glass, as well as a decorative welcome feature. As functional components, these modules also offer waterproofing, dustproofing, noise reduction, welcome functions, and battery level indication. Furthermore, varying the material, brightness, and color options available allows for a variety of decorative styles.

[0035] The prior art discloses an external water-cut structure, which includes a translucent decorative strip, the ends of which are bent to form a first clipping portion and a second clipping portion, and the first clipping portion and the second clipping portion are arranged opposite each other. For metal parts, the clipping portion can be formed by bending at both ends, but for injection molded parts, it is impossible to bend after molding. For injection molded structures that require clips at both ends, the complexity and feasibility of the mold structure molding must be considered during the mold design and plastic part manufacturing process.

[0036] Please refer to Figures 1 and 2. The related art provides a luminous water-cut structure 100, which may include: an exterior panel 1 (i.e., a mask), a luminous module 4, a back cover 5, a TPE sealing strip 9 with a steel belt 10, and other components.

[0037] Among them, the exterior panel 1 and the paint 2 are combined through a spraying process; the exterior panel 1 is laser engraved to form a luminous area 3 after spraying; the luminous module 4 is glued and fixed to the rear cover 5; the wiring harness 7 is connected to the luminous module 4 by welding, and is glued to the side wall of the rear cover 5 through double-sided tape 6; the rear cover 5 is fixed to the exterior panel 1 through double-sided tape / PU tape 8; the upper end buckle and the lower end buckle of the exterior panel 1 are assembled with the card slot of the TPE sealing strip 9 (including steel strip 10); the TPE sealing strip 9 enters the door panel sheet metal 200, and the front and rear end covers are inserted into the door panel sheet metal 200; the wiring harness 7 passes through the door panel sheet metal 200, and finally is powered on to the body control module to transmit signals.

[0038] The above-mentioned water-cutting method has the following disadvantages after adding the light-emitting module 4 inside:

[0039] 1) For the luminous water-cut structure 100, since it is installed between the window glass and the door panel sheet metal 200, the installation space is small. Due to the limited installation space, the structural design of the exterior panel 1 (i.e., the mask) and the back cover 5 is complicated. The two need to cooperate to form the upper end snap-on structure and the lower end snap-on structure at the same time, which leads to too many mold forming mechanisms for the mask and the back cover 5, which may eventually cause disadvantages such as difficult mold processing and poor project mass production.

[0040] 2) The back cover 5 is fixed to the exterior panel 1 via double-sided tape / PU glue 8. That is, the use of gluing and gluing processes to connect the two injection-molded parts will produce the following disadvantages: For the luminous water-cut structure 100, for the existing luminous water-cut structure 100, the gluing and gluing methods during installation are completed manually, which cannot effectively ensure the airtightness inside the water-cut, and thus cannot meet the long-term functional use requirements; and because the gluing and gluing methods are both completed manually during the installation of the water-cut module, product assembly problems cannot be completely eliminated, and the yield rate is low. In addition, the gluing and gluing methods also require the additional cost of double-sided tape 6 or glue.

[0041] 3) For the plastic luminous water-cut structure 100, since the photoelectric module is provided, the LED light source emits a large amount of heat when working, and the traditional pasting process and gluing process cannot effectively dissipate the heat.

[0042] Therefore, it is necessary to propose a luminous water-cut structure to solve at least one of the above problems.

[0043] Please refer to Figures 3 to 15 for a comprehensive description. The present application provides a water-cut assembly 100 for installation between a vehicle window glass 300 and a door panel 200. The water-cut assembly 100 may primarily include a water-cut body and a seal 9. A light-emitting water-cut assembly may also include a light-emitting module 4.

[0044] The water-cut body extends longitudinally along the first direction and may include an outer decorative panel 1 and a back cover 5 that are connected to each other. The outer decorative panel 1 has a first inner surface 111 facing the back cover 5 and a first outer surface 112 opposite to the first inner surface 111; the back cover 5 has a second inner surface 51 facing the outer decorative panel 1 and a second outer surface 52 opposite to the second inner surface 51. At least part of the area between the first inner surface 111 and the second inner surface 51 is sealed and fixed in a predetermined manner. Specifically, the predetermined manner may be welding, and of course, connection by other feasible sealing and fixing methods is not excluded. In the embodiments of the present application, welding is mainly used as an example for illustration. When the first inner surface 111 and the second inner surface 51 are sealed and fixed by forming a welding structure, a mounting cavity for mounting the light-emitting module 4 is formed.

[0045] Please refer to Figures 4 and 5 , in which the water-cut body extends longitudinally along a first direction, which matches the extension direction of the door outer panel stop. The extension direction of the water-cut body can be adaptively adjusted based on changes in the extension direction of the door outer panel stop, and this application does not impose specific limitations. For example, please refer to Figure 16 , the first direction can be parallel or substantially parallel to the vehicle's travel direction X.

[0046] The water-cut body may include an outer decorative plate 1 and a rear cover 5 that are connected to each other. The outer decorative plate 1 and the rear cover 5 are respectively integrally formed injection molded parts, that is, both can be integrally formed by injection molding to form a light-transmitting water-cut body structure.

[0047] In one embodiment of the present application, the exterior panel 1 and the back cover 5 are fixed to each other by forming a welding structure to form a mounting cavity for mounting the light-emitting module 4 .

[0048] Please refer to FIG. 6 , in which the exterior panel 1 and the rear cover 5 can be welded together by ultrasonic welding to form the welding structure (ie, the ultrasonic structure 8 ).

[0049] Among them, the principle of ultrasonic welding is as follows: when ultrasonic waves act on the contact surface of thermoplastic plastics, high-frequency vibrations of tens of thousands of times per second will be generated. This high-frequency vibration with a certain amplitude transmits ultrasonic energy to the welding area through the upper weldment. Since the welding area, that is, the interface between the two welds, has a large acoustic impedance, local high temperature will be generated. Due to the poor thermal conductivity of plastics, it cannot be dissipated in time for a while, and heat accumulates in the welding area, causing the contact surfaces of the two plastics to melt rapidly. After a certain amount of pressure is applied, it is fused into one. When the ultrasonic wave stops acting, the pressure is allowed to continue for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding, and the welding strength can be close to the strength of the raw materials. Overall, the use of ultrasonic welding to form an ultrasonic welded structure has the following advantages:

[0050] 1. Achieve reliable connection between the exterior panel 1 and the rear cover 5: Ultrasonic welding can achieve reliable connection between plastic materials, forming a strong weld, so that the workpiece has high strength and good sealing.

[0051] 2. Fast and efficient welding: Ultrasonic welding is a fast welding method that can complete the welding process in a short time and improve production efficiency.

[0052] 3. No additives required: Compared with other welding methods, ultrasonic welding does not require the use of additives such as welding agents or glue, avoiding additional material costs and environmental pollution.

[0053] 4. Smokeless and odorless: The ultrasonic welding process does not produce smoke, odor or harmful gases, providing a clean and environmentally friendly welding environment.

[0054] 5. Achieve precise control: Ultrasonic welding can precisely control welding parameters such as vibration frequency, amplitude and applied pressure to achieve fine adjustment and control of welding quality.

[0055] In addition, connecting the exterior panel 1 and the rear cover 5 by ultrasonic welding can effectively compress the space of the plastic luminous water-cut structure. The overall space volume is small and does not occupy the Y-direction space of the door sheet metal. The Y-direction space can be ≤10mm; and the structural layout can be adapted to any type of plastic luminous water-cut structure, with good versatility.

[0056] After ultrasonic welding is completed between the exterior panel 1 and the rear cover 5, an ultrasonic structure 8 can be formed between the exterior panel 1 and the rear cover 5. It should be noted that before ultrasonic welding, ultrasonic ribs can be provided at the joints of the rear cover 5 and / or the exterior panel 1. After ultrasonic welding is completed, the ultrasonic ribs will melt, thereby forming the ultrasonic structure 8 between the exterior panel 1 and the rear cover 5.

[0057] Please refer to Figures 5, 7 and 8 in combination. In one embodiment, the light emitting module 4 is fixedly mounted on the second inner surface 51 of the rear cover 5, and the exterior panel 1 is provided with a light emitting area 3 facing the light emitting module 4.

[0058] In this embodiment, the light-emitting module 4 includes a plurality of light-emitting elements, and the plurality of light-emitting elements can be arranged at intervals along the first direction. In addition, the light-emitting water-cut assembly can also be provided with paint 2, a light-emitting area 3, a wiring harness 7, etc. Specifically, the paint 2 can be provided on the first outer surface 112 of the exterior panel 1 by a spraying process. After spraying, the first outer surface 112 of the exterior panel 1 can be laser engraved to form the light-emitting area 3. The light-emitting module 4 can be fixed to the second inner surface 51 of the rear cover 5 by gluing. The wiring harness 7 can be connected to the light-emitting module 4 by welding and glued to the second outer surface 52 of the rear cover 5. The wiring harness 7 passes through the door panel sheet metal 200, and is energized with the body control module to transmit signals. Specifically, the wiring harness 7 can be fixed to the side wall position of the second outer surface 52 of the rear cover 5 by gluing with double-sided tape 6.

[0059] Of course, the connection method between the above-mentioned wiring harness 7 and the light-emitting module 4, and the fixing method between the wiring harness 7 and the back cover 5 can also be other methods and are not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0060] Please refer to Figures 5 and 6 in conjunction with each other. Regarding the method in which the back cover 5 is fixed to the exterior panel 1 through the ultrasonic structure 8, specifically when the structure is set, a stop portion 110 of a predetermined height is provided on the first inner surface 111 of the exterior panel 1 and located on the periphery of the light-emitting area 3; the back cover 5 is a cover body with an open end, which is buckled onto the periphery of the stop portion 110. The cover body has an open end, and before ultrasonic welding is performed, the ultrasonic ribs are provided on the end surface of the open end.

[0061] In this embodiment, prior to ultrasonic welding, ultrasonic ribs may be provided on the open end surface of the rear cover 5. Specifically, the dimensions of the ultrasonic ribs may vary depending on the matching dimensions of the exterior panel 1 and the rear cover 5, as well as the required connection strength between the two. For example, in the water jet assembly 100 used in the embodiment of this application, after considering various factors such as structural connection strength and cost-effectiveness, the ultrasonic ribs preferably have a height H between 0.6 mm and 0.8 mm and a width W between 0.6 mm and 0.8 mm.

[0062] The stop portion 110 of the exterior panel 1 is arranged on the inner side of the rear cover 5. It can be used to assist in positioning the rear cover 5 during welding, and can also be used to stop the molten material generated during welding to prevent the molten material from overflowing. In addition, it can also stop the welding chips generated during welding to prevent the welding chips from entering the cavity between the exterior panel 1 and the rear cover 5.

[0063] Before ultrasonic welding, a predetermined gap G is formed between the side wall of the cover body near the opening end and the stopper 110, and the predetermined gap G is between 0.1 mm and 0.3 mm. The height H1 of the stopper 110 can be between 2 mm and 3 mm.

[0064] The stopper 110 can be integrally injection molded with the exterior panel 1. Taking into account various factors such as the functions to be realized by the structure, production costs, and production processes, the height H1 of the stopper 110 can be between 2 mm and 3 mm. When the height H1 of the stopper 110 is between 2 mm and 3 mm, it can reliably meet the functions of preventing material overflow and stopping welding shavings during ultrasonic welding, and can also be injection molded at a relatively economical production cost. If the height of the stopper 110 is too low, for example, less than 2 mm, it may not be able to reliably meet the above-mentioned functions of preventing material overflow and stopping welding shavings. If the height of the stopper 110 is too high, for example, higher than 3 mm or even higher than 5 mm, it may greatly increase the injection pressure, reduce economic efficiency, and even directly affect formability.

[0065] The stopper 110 is fitted with a gap between the sidewall of the rear cover 5 , and a predetermined gap G between the two may be between 0.1 mm and 0.3 mm.

[0066] When the predetermined gap G between the two is too small, for example, less than 0.1 mm, sufficient space cannot be formed between the stop portion 110 and the side wall of the back cover 5 to prevent the molten material from overflowing; when the predetermined gap G is too large, for example, greater than 0.3 mm, or even greater than 0.5 mm, the limiting effect of the stop portion 110 cannot be exerted. At this time, there may be a large surface difference after the exterior panel 1 is connected to the back cover 5, affecting the appearance of the product and even directly affecting the yield rate of the product.

[0067] It should be noted that the embodiments listed in this application are primarily described with the ultrasonic ribs disposed on the rear cover 5. Because ultrasonic welding requires force application points on the structural member where the ultrasonic ribs are disposed, and a certain amount of pressure is applied, and the exterior panel 1 has high requirements for appearance, to prevent any adverse effects on the exterior panel's appearance, this application disposes the ultrasonic ribs on the rear cover 5. Of course, this application does not exclude embodiments in which the ultrasonic ribs are disposed on the exterior panel 1, or in which the ultrasonic ribs are disposed on both the rear cover 5 and the exterior panel 1.

[0068] Furthermore, the exterior panel 1 has upper and lower ends 114 that face each other in the height direction. A groove 115 is formed between the lower end 114 and the stopper 110 to provide a clearance fit with the side wall of the cover. The groove 115 formed between the lower end 114 of the exterior panel 1 and the stopper 110 can be used to assist in positioning the cover after a clearance fit is achieved before ultrasonic welding.

[0069] In a specific embodiment, the stopper 110 is a circumferentially closed ring structure. When the stopper 110 is a circumferentially closed ring structure, it can reliably form a circumferential seal with the exterior panel 1, and the mold structure corresponding to the injection molding process is simple and the production cost is low.

[0070] Of course, in some other embodiments, the stop portion 110 can be partially arranged in the circumferential direction, for example, the stop portion 110 is arranged near the lower middle part of the exterior panel 1, and a receiving groove is opened on the end face of the open end of the rear cover 5, and the receiving groove is used to provide space for the molten material to overflow.

[0071] The water-cut assembly 100 provided in the embodiment of the present application changes the fixing process between the exterior panel 1 and the rear cover 5 from pasting and gluing to a structural fixed installation. Specifically, by fixing the exterior panel 1 and the rear cover 5 with a welding structure (especially welding with ultrasonic welding technology), a series of disadvantages brought about by the existing pasting and gluing methods are overcome, and various technical problems caused by the double-sided tape 6 / PU glue fixing method between the exterior panel 1 and the rear cover 5 in the prior art can be solved.

[0072] The water-cut assembly 100 provided in the embodiment of the present application solves the problems of the existing luminous water-cut structure mold having multiple molding mechanisms, difficult processing, and poor mass production by improving the structure of the water-cut body, namely the exterior decorative panel 1 and the back cover 5. It can simplify the structure of the mold, greatly improve the mass production of the product, and realize that the optoelectronic module can be universally arranged in the space of the plastic water-cut assembly while maintaining good optoelectronic performance.

[0073] Please refer to Figures 8, 12, or 14. The water jet assembly 100 may further include a sealing member 9 that interfaces with the water jet body. The sealing member 9 extends longitudinally along a first direction and has an inner surface facing the door panel sheet metal 200 and an outer surface facing away from the door panel sheet metal 200. A positioning portion is provided on the outer surface. Connecting mechanisms are provided on the water jet body to interface with the positioning portion of the sealing member 9. The connecting mechanisms are spaced apart along the first direction.

[0074] In this embodiment, the water jet assembly 100 may further include a sealing member 9, which is generally strip-shaped and extends along the first direction. Specifically, the sealing member 9 may be in the form of a TPE sealing strip. Of course, the specific material of the sealing member 9 may vary depending on the actual sealing material requirements and material improvements, and this application does not impose any specific restrictions here.

[0075] A skeleton is also provided inside the seal 9 for supporting and shaping the seal 9. The skeleton can be a steel strip. Of course, the specific material of the support strip is not limited to the above examples. In the embodiment of the present application, a steel strip is used as an example for explanation.

[0076] As shown in Figure 3, the water-cut assembly 100 may further include a front cover 101 and a rear cover 102. During assembly, the TPE sealing strip may be inserted into the door panel sheet metal 200, and the front cover 101 and the rear cover 102 may be inserted into the door panel sheet metal 200.

[0077] The water-cut body is provided with a connecting mechanism connected to the sealing member 9, and the connecting mechanism is arranged at intervals along the first direction, that is, a segmented structure is adopted to solve the problems of difficult processing of molds of existing plastic luminous water-cut structures and poor mass production of projects.

[0078] The manufacturing process of molds for plastic luminous water-cut structures in related technologies often requires machining complex concave and convex shapes on the mold, which increases processing difficulty and time, and may affect the quality and stability of the mold. However, the connection mechanism of the present application is arranged at intervals and in a segmented manner, which effectively solves these problems by dividing the concave and convex shapes of the mold into multiple small segments for processing.

[0079] Specifically, with the segmented layout, the mold's concave and convex shapes are divided into multiple small blocks, each of which can be processed independently, making the machining process much simpler (because the shape of each block is relatively simple and the machining difficulty is relatively low). In addition, since each block can be processed independently, multiple machine tools can be used for simultaneous processing, greatly reducing processing time and improving production efficiency.

[0080] The segmented layout can also improve the quality and stability of the mold. Since each small block can be processed independently, the processing quality can be better controlled to ensure that the accuracy and quality of each small block meet the requirements.

[0081] At the same time, if there is a problem with a small part of the mold, only the small part can be replaced without remaking the entire mold, which greatly reduces costs and risks.

[0082] In short, the connection mechanism of the water-cut body adopts a segmented arrangement, which solves the problems of difficult processing and poor mass production of the mold by dividing the concave and convex shape of the mold into multiple small blocks for processing, simplifies the processing process, improves production efficiency, and at the same time improves the quality and stability of the mold.

[0083] Please refer to Figures 5, 8, 10 to 11. In one embodiment, the connecting mechanism includes: a connecting member 14 arranged on the outer surface of the water-cut body, the positioning portion includes a first opening 131 that cooperates with the connecting member 14, and the connecting member 14 can be connected to the first opening 131.

[0084] Specifically, the connecting mechanism may include a connecting member 14 arranged on the second outer surface 52 of the back cover 5, the connecting member 14 having a first end close to the second outer surface 52 and a second end away from the second outer surface 52, a snap-fit ​​head 141 is provided at the second end, and a first opening 131 is provided on the sealing member 9 to cooperate with the snap-fit ​​head 141, and the snap-fit ​​head 141 can pass through the first opening 131 and snap-fit ​​with the sealing member 9 outside the first opening 131.

[0085] In this embodiment, the connector 14 can be integrally injection molded with the back cover 5. When the connector 14 is integrally injection molded with the back cover 5, compared to directly inserting the connector 14 on the back cover 5, the structure of the back cover 5 does not need to be destroyed, and the connection with the back cover 5 is more secure and reliable. In addition, the installation steps can be saved, and the operation is simple.

[0086] As shown in FIG4 , the connector 14 may include a plurality of connectors 14 , which are arranged at predetermined intervals along the first direction. When the connectors 14 are injection-molded integrally with the back cover 5 and arranged at intervals along the first direction, a typical segmented structure is formed, achieving the technical effects of the aforementioned segmented structure.

[0087] The predetermined spacing between two adjacent connectors 14 is between 100 mm and 120 mm. The predetermined spacing between two adjacent connectors 14 can be determined based on the structure and weight of the water-cut body, as well as the required strength of the connection. When the predetermined spacing between two adjacent connectors 14 is within this range, structural connection strength, cost-effectiveness, and processability can be optimally balanced.

[0088] In this embodiment, the connector 14 has a bottom end that engages with the rear cover 5 and a top end that is spaced away from the rear cover 5. A snap-fit ​​head 141 is provided at the top end (i.e., the end facing away from the outer surface of the water-cut body). The seal 9 is provided with a first opening 131 that mates with the snap-fit ​​head 141. The snap-fit ​​head 141 can pass through the first opening 131 and snap-fit ​​with the seal 9 outside the first opening 131.

[0089] When the water-cut body and the seal 9 are assembled, the locking head 141 passes through the first opening 131. After the locking head 141 passes through the first opening 131, the locking head 141 can be engaged with the seal 9 outside the first opening 131 to form a locking connection structure to prevent the locking head 141 from loosening from the first opening 131.

[0090] Specifically, the connecting member 14 is provided with a deformation portion. When the locking head 141 is squeezed by an external force, the deformation portion causes the locking head 141 to shrink and deform radially inward. When the locking head 141 is no longer subjected to the external force, the locking head 141 automatically returns to its original shape.

[0091] Among them, the first opening 131 can be specifically designed according to the outer contour size of the locking head 141. Specifically, the present application does not make any specific restrictions on the shape, structure and size of the first opening 131. Specifically, when the first opening 131 is matched with the connector 14, a certain gap can be formed. That is, the first opening 131 and the connector 14 can be gap-matched. The first opening 131 can be used to discharge the accumulated water in the cavity between the water-cut body and the seal 9 to the outside. In addition, for the water-cut assembly 100 provided with the light-emitting module 4, the light-emitting module 4 will generate a certain amount of heat during use. If the heat accumulates in the closed cavity and cannot be quickly evacuated to the outside, it will directly affect the service life of the light-emitting module 4. The first opening 131 can be used to dissipate the heat in the cavity between the water-cut body and the seal 9 to the outside.

[0092] Please refer to Figures 10 and 11 in combination. In a specific embodiment, the connecting member 14 includes: a locking head 141 and a connecting section 142 arranged between the locking head 141 and the water-cut body. The cross-sectional outer contour size of the locking head 141 is larger than the cross-sectional outer contour size of the connecting section 142, and the deformation portion includes a groove 143 arranged from the second end toward the first end.

[0093] In this embodiment, the connector 14 can specifically be a "mushroom head"-like nail post structure, which can include a larger engaging head 141 and a relatively smaller connecting section 142. The deformed portion of the connector 14 can be a slot 143 provided from the second end to the first end. After the slot 143 is provided, the engaging head 141 can be divided into a first portion and a second portion. When the connector 14 is assembled with the first opening 131, the slot 143 is used to bring the first portion and the second portion closer together, allowing the engaging head 141 to pass through the first opening 131. After passing through the first opening 131, the engaging head 141 can automatically return to its original shape and engage with the sealing member 9.

[0094] Of course, the specific form of the above-mentioned deformation part can also be other forms and is not limited to the above description. Technical personnel in the relevant field may make other changes inspired by the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the scope of protection of this application.

[0096] The sealing member 9 extends longitudinally along the first direction, and the sealing member 9 has an inner surface facing the door panel sheet metal 200 and an outer surface facing away from the door panel sheet metal 200. The outer surface of the sealing member 9 is provided with at least one card slot. The connecting mechanism may further include: a snap-fit ​​portion provided on the water-cut body and capable of snapping into the card slot. The snap-fit ​​portion may be a buckle provided on the exterior panel 1 or the rear cover 5. For example, the first buckle 11 may be provided on the top of the exterior panel 1. The card slot is provided through the first direction, and the first buckle 11 is provided intermittently along the first direction.

[0097] To ensure the universality of the seal 9, its outer surface can be provided with a first slot 91 and a second slot 92, staggered in height. A clip that engages with the first slot 91 or the second slot 92 can be provided on at least one of the exterior panel 1 and the rear cover 5. The slot and clip form a connection structure, which, combined with the aforementioned mating arrangement of the connector 14 and the first opening 131, further ensures the reliable installation of the water jet assembly 100. The first slot 91 can be higher than the second slot 92 in height.

[0098] Of course, the seal 9 can also be provided with the first card groove 91 only on the upper part, or the second card groove 92 only on the lower part. Accordingly, a buckle that matches the first slot 143 can be provided on the exterior panel 1, or a buckle that matches the second card groove 92 can be provided on the rear cover 5.

[0099] Among them, along the first direction, the buckle can be arranged in sections to form a segmented structure, which can achieve the technical effect of the above-mentioned segmented structure.

[0100] Please refer to FIG. 8 . In a specific embodiment, the first slot 91 is located higher than the second slot 92 . The exterior panel 1 is provided with a first buckle 11 that is engaged with the first slot 91 .

[0101] In this embodiment, a first latching groove 91 is provided on the upper portion of the seal 9, and the outer panel 1 is provided with a first latch 11 that engages with the first latching groove 91. The first latching groove 91 and the first latch 11 cooperate to form a latching structure. When the latching structure is located at the upper portion, it not only facilitates the fastening of the outer panel 1 to the seal 9, but also achieves a certain degree of dustproof and waterproof effect.

[0102] Please refer to Figures 12, 13, 14 and 15. In some embodiments, the seal 9 extends longitudinally along the first direction, the positioning portion includes a first card slot 91 and a second card slot 92 staggered along the height direction, and the connecting mechanism may include: a first clip 11 and a second clip 12 provided on the water-cut body, the first clip 11 is used to cooperate with the first card slot 91 to form a first clip mechanism, the second clip 12 is used to cooperate with the second card slot 92 to form a second clip mechanism, and the first clip mechanism and the second clip mechanism are staggered along the first direction.

[0103] In this embodiment, Figures 12 and 13 illustrate two adjacent cross-sections in a first direction. The first clips 11 are provided on the exterior panel 1, and the second clips 12 are provided on the rear cover 5. The first clips 11 and the second clips 12 are arranged alternately along the first direction. The first clips 11 and the second clips 12 employ a segmented structure, achieving the aforementioned technical effects of the segmented structure.

[0104] In addition, for the exterior panel 1, it only needs to be provided with a bent first clip 11 at one end, such as the top end, and no further provision is required at the other end, such as the bottom end; for the back cover 5, it only needs to be provided with a bent second clip 12 at one end, such as the bottom end, and no further provision is required at the other end, such as the top end. This can greatly reduce the difficulty of manufacturing the mold, simplify the mold structure, and reduce weak positions during injection molding of plastic parts.

[0105] Specifically, as shown in FIG4 , the width of the first snap 11 or the second snap 12 along the first direction is between 10 mm and 20 mm. Along the first direction, the spacing between two adjacent first snaps 11 is between 40 mm and 60 mm, and the spacing between two adjacent second snaps 12 is between 40 mm and 60 mm. In a cross section perpendicular to the first direction, either the first snap 11 or the second snap 12 engages with the seal 9.

[0106] In this embodiment, the width of the first buckle 11 or the second buckle 12 and the spacing between two adjacent buckles can meet the connection strength when the buckle and the seal 9 are matched, while also taking into account the feasibility and economy of production.

[0107] In addition, on a cross section perpendicular to the first direction, the first buckle 11 and the second buckle 12 can be staggered, that is, on the same cross section, the first buckle 11 and the second buckle 12 do not need to be engaged with the seal 9 at the same time.

[0108] In one embodiment, the exterior panel 1 is at least partially covered on the periphery of the rear cover 5 , and an accommodation space for installing a wiring harness is formed between the first inner surface 111 of the exterior panel 1 extending to the periphery of the rear cover 5 and the second outer surface 52 of the rear cover 5 .

[0109] In this embodiment, the upper end of the exterior panel 1 wraps around the upper portion of the rear cover 5, forming a first snap 11 that engages with the first slot 91 of the seal 9. A space for mounting the wiring harness 7 is also formed between the first inner surface 111 of the exterior panel 1 and the second outer surface 52 of the rear cover 5. The wiring harness 7 can be secured to the second outer surface 52 of the rear cover 5. Specifically, as described above, the wiring harness 7 can be secured to the sidewall of the second outer surface 52 of the rear cover 5 using double-sided tape 6.

[0110] In one embodiment, the water jetting assembly 100 may include a sealing member 9 connected to the water jetting body, the sealing member 9 extending longitudinally along the first direction. A frame 10 is disposed within the sealing member 9, and a second opening 132 is provided on a side of the sealing member 9 that is assembled with the water jetting body and penetrates the frame 10.

[0111] As mentioned above, a skeleton 10 is provided inside the sealing member 9 for supporting and shaping the sealing member 9 .

[0112] For the light-emitting module 4 used in the embodiment of the present application, the light-emitting element is specifically an integrated structure of an IC chip and an LED. During use, the heat generated will be greatly increased compared to traditional strip-shaped light-emitting elements.

[0113] The seal 9 may be provided with a second opening 132 on the side close to the back cover 5, and the second opening 132 is used for drainage and heat dissipation. Specifically, for the above-mentioned embodiment in which the first opening 131 is provided, the second opening 132 may be the same opening as the first opening 131, that is, no additional setting is required. For the embodiment in which the first opening 131 is not provided, a second opening 132 may be provided, and the second opening 132 may be used to discharge the accumulated water in the cavity between the water-cut body and the seal 9. In addition, for the water-cut assembly 100 provided with the light-emitting module 4, the light-emitting module 4 will generate a certain amount of heat during use. If the heat accumulates in the closed cavity and cannot be quickly evacuated to the outside, the service life of the light-emitting module 4 will be directly affected. The heat in the cavity between the water-cut body and the seal 9 can be dissipated to the outside by using the second opening 132.

[0114] The number of the second openings 132 can also be set to multiple, and the multiple second openings 132 can be arranged at intervals along the first direction. In particular, since the second openings 132 have the function of draining accumulated water, in order to drain as much accumulated water as possible in the cavity between the water-cutting body and the sealing member 9, the position of the second openings 132 can be set as low as possible. Of course, the positions of the second openings 132 can also be staggered along the height direction.

[0115] A vehicle is also provided in an embodiment of the present application, and the vehicle mainly includes the above-mentioned water-cutting assembly 100.

[0116] The vehicle can achieve the technical effects achieved by the implementation of the water-cut assembly 100 by setting the water-cut assembly 100. For details, please refer to the detailed description of the above implementation, and this application will not go into details here.

[0117] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention.
