The photoelectric module for automobile door is one kind of outer decoration part with both photoelectric function and appearance requirement. The water-cut photoelectric module is arranged on an outer plate spigot of an automobile door, so that the sealing between the automobile door and the window glass can be realized, and the decorative effect of a welcome can be realized; as a functional part, the water-cut photovoltaic module further has: waterproof, dustproof, noise reduction, welcome, electric quantity display and other functions; in addition, the different decorative styles can be provided by selecting different materials, brightness and colors for the appearance.

The utility model discloses an outer water cuts structure in the prior art, it includes the printing opacity ornamental strip, the both ends of printing opacity ornamental strip are buckled and are formed first joint portion with second joint portion, first joint portion with second joint portion sets up in opposite directions. For the metal piece, the clamping parts can be formed in a bending mode at two ends, however, for the injection molding piece, bending cannot be performed after molding. For the injection molding structure with buckles at two ends, the plastic part needs to be mainly considered in the manufacturing process of the plastic part during the mold design, and the problems of complexity, feasibility and the like of the mold structure molding are solved.

Referring to fig. 1 and 2, a light-emitting water cutting structure 100 is provided in the related art, and the light-emitting water cutting structure 100 may include: the outer decorative plate 1 (namely a face mask), the light-emitting module 4, the rear cover 5, the TPE sealing strip 9 provided with a steel belt 10 and the like.

Wherein the outer decorative plate 1 and the paint 2 are combined through a spraying process; the outer decorative plate 1 is sprayed and then is processed into a luminous area 3 by laser engraving; the light-emitting module 4 is stuck and fixed on the rear cover 5; the wire harness 7 is connected with the light-emitting module 4 through welding and is stuck on the side wall of the rear cover 5 through the double faced adhesive tape 6; the rear cover 5 is fixed on the outer decorative plate 1 through double faced adhesive tape/PU adhesive tape 8; the upper end buckle and the lower end buckle of the outer decorative plate 1 are assembled with the clamping groove of the TPE sealing strip 9 (comprising a steel belt 10); the TPE sealing strip 9 is inserted into the door sheet metal 200, and the front end cover and the rear end cover are inserted into the door sheet metal 200; the wire harness 7 passes through the door sheet metal 200 and finally is electrified with the vehicle body control module to transmit signals.

The disadvantages of the water cut after adding the light emitting module 4 inside include the following:

1) For the luminous water cutting structure 100, because the luminous water cutting structure is installed between the window glass and the door sheet metal 200, the installation space is smaller and limited by the limited installation space, so that the structural designs of the outer decorative plate 1 (namely the face mask) and the rear cover 5 are complex, the upper end clamping structure and the lower end clamping structure are required to be formed simultaneously by matching the two structures, and further, the die forming mechanisms of the face mask and the rear cover 5 are excessive, and finally, the defects of difficult die processing, poor project mass production and the like can be caused.

2) The rear cover 5 is fixed on the outer decorative plate 1 through double faced adhesive tape/PU adhesive tape 8, namely, the following defects are generated when two injection molding pieces are connected by adopting a pasting process and a gluing process: for the luminous water cutting structure 100, for the existing luminous water cutting structure 100, the mode of pasting and gluing during installation is completed by manual operation, so that the air tightness of the water cutting inside cannot be effectively ensured, and further the long-term functional use requirement cannot be met; and because the modes of pasting and gluing are completed through manual operation when the water cutting module is installed, the problem of product assembly can not be completely removed, and the yield is lower. In addition, the auxiliary material cost of the double faced adhesive tape 6 or glue is increased by adopting the modes of pasting and gluing.

3) For the plastic luminous water cutting structure 100, due to the arrangement of the photoelectric module, the LED light source emits a large amount of heat during working, and the traditional pasting process and the gluing process cannot effectively lead out the heat.

For this reason, there is a need to propose a luminous water cut structure which solves at least one of the above-mentioned problems.

Referring to fig. 3 to 15 in combination, in the embodiment of the present application, a water cutting assembly 100 is provided for being installed between a window glass 300 and a door panel sheet 200, and the water cutting assembly 100 may mainly include: a water cut body and a seal 9. For the luminous water cutting assembly, the luminous water cutting assembly can further comprise a luminous module 4.

The water cutting body extends lengthwise along a first direction and can comprise an outer decorative plate 1 and a rear cover 5 which are butted. The outer plaque 1 has a first inner surface 111 facing the rear cover 5, a first outer surface 112 opposite to the first inner surface 111; the rear cover 5 has a second inner surface 51 facing the outer plaque 1 and a second outer surface 52 opposite to the second inner surface 51. At least a part of the area between the first inner surface 111 and the second inner surface 51 is sealed and fixed in a predetermined manner. In particular, the predetermined means may be welding, although it is not excluded that the connection is made by other possible sealing means, and in the embodiment of the present application, the welding means are mainly exemplified. The first inner surface 111 and the second inner surface 51 are sealed and fixed by forming a welding structure therebetween to form a mounting cavity for mounting the light emitting module 4.

Referring to fig. 4 and 5, the water cutting body extends longitudinally along a first direction, and the first direction matches with the extending direction of the spigot of the outer panel of the vehicle door. The extending direction of the water cutting body can be adaptively adjusted according to the change of the extending direction of the outer surface spigot of the vehicle door, and the application is not particularly limited herein. For example, referring to fig. 16 in combination, the first direction may be a direction parallel or substantially parallel to the vehicle traveling direction X.

The water cutting body may comprise an outer plaque 1 and a rear cover 5 which are butted. The outer decoration plate 1 and the rear cover 5 are respectively injection molded pieces which are integrally molded, namely, the outer decoration plate and the rear cover can be integrally molded through injection molding, so that a light-transmitting water-cutting body structure is formed.

In one embodiment of the present application, the outer plaque 1 and the rear cover 5 are fixed by forming a welding structure therebetween to form a mounting cavity for mounting the light emitting module 4.

Referring to fig. 6, the welding structure (i.e., the ultrasonic structure 8) may be formed between the exterior trim panel 1 and the rear cover 5 by ultrasonic welding.

Wherein, the ultrasonic welding principle is as follows: when the ultrasonic wave acts on the thermoplastic plastic contact surface, tens of thousands of times per second high-frequency vibration can be generated, the high-frequency vibration reaching a certain amplitude is transmitted to the welding area through the upper welding piece, and the local high temperature can be generated because the acoustic resistance of the welding area, namely the interface of two welding areas is large. And because the plastic has poor heat conductivity, the heat cannot be timely emitted at one time, and the heat is accumulated in the welding area, so that the contact surfaces of the two plastics are quickly melted, and the two plastics are fused into a whole after a certain pressure is applied. After the ultrasonic wave stops acting, the pressure is kept for a few seconds to solidify and form the material, so that a firm molecular chain is formed, the purpose of welding is achieved, and the welding strength can be close to the strength of the raw material. Overall, the formation of an ultrasonic welding structure by ultrasonic welding has the following advantages:

1. The reliable connection of the outer decorative plate 1 and the rear cover 5 is realized: the ultrasonic welding can realize reliable connection between plastic materials to form a strong welding line, so that the workpiece has high strength and good sealing property.

2. Welding is fast and efficient: ultrasonic welding is a rapid welding method, can finish the welding process in a short time, and improves the production efficiency.

3. No additives are needed: compared with other welding methods, the ultrasonic welding method does not need to use additives such as welding agent or glue, and the like, thereby avoiding additional material cost and environmental pollution.

4. No smoke and smell: the ultrasonic welding process does not generate smoke, smell or harmful gas, and provides a clean and environment-friendly welding environment.

5. Realizing accurate control: ultrasonic welding allows precise control of welding parameters such as vibration frequency, amplitude and applied pressure to achieve fine tuning and control of welding quality.

In addition, the outer decorative plate 1 and the rear cover 5 are connected in an ultrasonic welding mode, so that the luminous water-cut structural space of plastic can be effectively compressed, the whole space is small in size, the Y-direction space of the door sheet metal is not occupied, and the Y-direction space can be less than or equal to 10mm; and the structural arrangement can be matched with any plastic luminous water cutting structure, and the universality is good.

When the outer plaque 1 and the rear cover 5 can be welded by ultrasonic wave, an ultrasonic wave structure 8 can be formed between the outer plaque 1 and the rear cover 5. It should be noted that: before the ultrasonic welding, ultrasonic ribs may be provided at the butt joint position of the rear cover 5 and/or the exterior panel 1, and after the ultrasonic welding is completed, the ultrasonic ribs may be melted, thereby forming an ultrasonic structure 8 between the exterior panel 1 and the rear cover 5.

Referring to fig. 5, 7 and 8, in one embodiment, the light emitting module 4 is fixedly mounted on the second inner surface 51 of the rear cover 5, and the outer decoration board 1 is provided with a light emitting area 3 opposite to the light emitting module 4.

In this embodiment, the light emitting module 4 includes a plurality of light emitting elements, which may be arranged at intervals along the first direction. In addition, the luminous water cutting assembly can be further provided with paint 2, luminous areas 3, wire harnesses 7 and the like. Specifically, paint 2 may be disposed on the first outer surface 112 of the exterior trim panel 1 by a spray process. The first outer surface 112 of the outer plaque 1 may be coated and then the light emitting area 3 may be laser etched. The light emitting module 4 may be fixed to the second inner surface 51 of the rear cover 5 by means of an adhesive. The wire harness 7 may be connected to the light emitting module 4 by welding and adhered to the second outer surface 52 of the rear cover 5. The wire harness 7 passes through the door sheet metal 200 and is electrified with the vehicle body control module to transmit signals. The wire harness 7 may be fixed to the side wall of the second outer surface 52 of the rear cover 5 by means of a double-sided tape 6.

Of course, the connection manner of the wire harness 7 and the light emitting module 4 and the fixing manner of the wire harness 7 and the rear cover 5 may be other manners, and are not limited to the above description, and other modifications may be made by those skilled in the art in light of the technical spirit of the present application, but all the functions and effects achieved by the present application are included in the protection scope of the present application as long as they are the same or similar to the present application.

Referring to fig. 5 and fig. 6 in combination, for the manner in which the rear cover 5 is fixed to the exterior board 1 through the ultrasonic structure 8, specifically, when the structure is set, a stop portion 110 with a predetermined height is disposed on the first inner surface 111 of the exterior board 1 and located at the periphery of the light emitting area 3; the rear cover 5 is a cover body with an opening at one end, and is buckled on the periphery of the stop part 110, the cover body is provided with an opening end, and the ultrasonic ribs are arranged on the end face of the opening end before ultrasonic welding.

In the present embodiment, an ultrasonic rib may be provided on the end surface of the open end of the rear cover 5 before ultrasonic welding. Specifically, the size of the ultrasonic rib may be different according to the matching size of the external decorative plate 1 and the rear cover 5, the connection strength requirement of the two, and the like. For example, in the water cutting assembly 100 used in the embodiments of the present application, the ultrasonic ribs preferably have a height H of 0.6 mm to 0.8 mm and a width W of 0.6 mm to 0.8 mm, in consideration of various factors such as the connection strength of the structure and cost effectiveness.

The stopper 110 of the exterior trim 1 is provided inside the rear cover 5, and can be used for assisting positioning of the rear cover 5 during welding, stopping of molten material generated during welding, preventing overflow of molten material, stopping of welding scraps generated during welding, and preventing welding scraps from entering a cavity between the exterior trim 1 and the rear cover 5.

Wherein, before ultrasonic welding, the cover body forms a predetermined gap G between the side wall near the open end and the stopper 110, the predetermined gap G is between 0.1 mm and 0.3 mm, and the height H1 of the stopper 110 may be between 2 mm and 3 mm.

The stop portion 110 may be integrally injection molded with the outer decorative plate 1, and the height H1 of the stop portion 110 may be between 2 mm and 3 mm in consideration of various factors such as functions, production cost, and production process implemented by the structure. When the height H1 of the stopper 110 is between 2 mm and 3 mm, it can reliably satisfy both the function of preventing material from overflowing and stopping welding scraps when performing ultrasonic welding and injection molding at a relatively economical production cost. If the height of the stopping portion 110 is too low, for example, less than 2 mm, the above-mentioned functions of preventing the material from overflowing and stopping the welding scraps may not be reliably satisfied, and if the height of the stopping portion 110 is too high, for example, more than 3 mm and even more than 5 mm, the injection molding pressure may be greatly increased, and the economy may be reduced and even the formability may be directly affected.

The stopper 110 is clearance-fitted with the sidewall of the rear cover 5, and a predetermined gap G therebetween may be between 0.1 mm and 0.3 mm.

When the predetermined gap G therebetween is too small, for example, less than 0.1 mm, a sufficient space for preventing the molten material from overflowing cannot be formed between the stopper 110 and the sidewall of the rear cover 5; 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 achieved, and at this time, a large surface difference may exist after the outer decoration board 1 is connected with the rear cover 5, which affects the appearance of the product, or even directly affects the yield of the product.

In the embodiments of the present application, the ultrasonic ribs are mainly disposed on the rear cover 5 for development, and when the ultrasonic welding is performed, it is necessary to provide a force application point for the structural member provided with the ultrasonic ribs, and perform a certain pressing operation; in contrast, the exterior trim 1 has a high requirement for the exterior, and therefore, in order to prevent the exterior trim from being adversely affected, the ultrasonic ribs are provided on the rear cover 5 in the present application. Of course, the application does not exclude embodiments in which the ultrasonic ribs are provided on the exterior panel 1 or in which the ultrasonic ribs are provided on the rear cover 5 and the exterior panel 1.

Further, the outer panel 1 has opposite upper and lower ends 114 in the height direction, and a groove 115 for clearance-fitting with the side wall of the cover is formed between the lower end 114 and the stopper 110. The recess 115 formed between the lower end 114 of the exterior board 1 and the stopper 110 is used to assist positioning after clearance fit with the lid body before ultrasonic welding of the two.

In a specific embodiment, the stop 110 has a closed annular structure in the circumferential direction. When the stop portion 110 has a closed annular structure in the circumferential direction, the stop portion can reliably form circumferential sealing with the outer decorative plate 1, and the mold corresponding to the injection molding process has a simple structure and low manufacturing cost.

Of course, in other embodiments, the stopper 110 may be provided with a portion in the circumferential direction, for example, the stopper 110 may be provided near the middle lower portion of the exterior sheathing panel 1, and an accommodating groove may be provided on the end surface of the open end of the rear cover 5, with which a space for the molten material to overflow may be provided.

According to the water cutting assembly 100 provided by the embodiment of the application, the process mode of fixing the outer decorative plate 1 and the rear cover 5 is changed from a bonding and gluing mode to a structure fixing mode, specifically, the outer decorative plate 1 and the rear cover 5 are fixed by adopting a welding structure (particularly adopting an ultrasonic welding technology for welding), a series of defects caused by the existing bonding and gluing mode are overcome, and various technical problems caused by adopting a double-sided adhesive 6/PU adhesive fixing mode between the outer decorative plate 1 and the rear cover 5 in the prior art can be solved.
