Description

Technical Field

[0001] This application relates to light-emitting devices, seats, and vehicles. Background Technology

[0002] Seat products, such as car seats, are constantly being optimized to improve the user experience. Some seats are equipped with lighting devices on the backrest for purposes such as enhancing the appearance and providing illumination; these lighting devices typically consist of two parts: a light-emitting strip and a connecting structure for mounting the light-emitting strip, such as a bracket.

[0003] However, in some comparative designs, the gaps between the light-emitting strip and components such as the bracket and back panel are uneven, resulting in an unsightly appearance; in some comparative designs, the light-emitting device is mainly installed to the back panel by adhesive bonding, resulting in poor odor, long assembly cycle, and poor connection reliability; in some comparative designs, the installation structure of the light-emitting device is complex, resulting in an increase in the overall thickness of the back panel structure, which is not conducive to the compactness of the seat.

[0004] In view of the above, the inventors of this application propose a light-emitting device, a seat, and a vehicle to solve at least one or a combination of the above technical problems. Utility Model Content

[0005] The purpose of this application is to provide a light-emitting device.

[0006] Another objective of this application is to provide a seat.

[0007] Another objective of this application is to provide a means of transportation.

[0008] According to a first aspect of this application, a light-emitting device is used for backplate light emission. The light-emitting device includes: a light-emitting strip, the light-emitting strip including a light-emitting part and a connecting part extending from the side of the light-emitting part; a bracket, the bracket being disposed at the edge of the backplate for mounting the light-emitting strip; the connecting part of the light-emitting strip being connected to the bracket; the connecting part having a positioning hole, and the bracket having a positioning post at a position corresponding to the positioning hole, the positioning post being inserted into the positioning hole to define the mounting position of the light-emitting strip.

[0009] The inventors discovered that the uneven and unsightly gaps between the light-emitting strip and components such as the bracket and backplate are mainly caused by the difficulty in properly installing the light-emitting strip. Since the light-emitting strip and bracket are usually fixed with adhesive, and the light-emitting strip is generally flexible and elongated, it is easy for the strip to deviate from its installation position during the assembly of the light-emitting device. Furthermore, it is difficult to ensure the quality of the adhesive bonding process (especially under manual operation), leading to misalignment, wavy wrinkles, and other issues, resulting in uneven and unsightly installation gaps. By setting positioning posts on the bracket and positioning holes at the connection point of the light-emitting strip, the positioning posts can be inserted into the positioning holes during the assembly of the light-emitting device, thus roughly defining the light-emitting strip. Its installation location facilitates proper placement of the light-emitting strip, reduces the difficulty of gluing, and improves installation quality. Furthermore, after assembly, the positioning posts and holes still serve to define the fixed position of the light-emitting strip. Compared to solutions that rely solely on gluing to fix the bracket and light-emitting strip, the use of positioning posts and holes makes the connection more stable and reliable. In addition, some comparative solutions add support components to the light-emitting strip, such as rigid plastic parts, increasing its rigidity and mitigating the uneven and unsightly installation gaps by addressing the strip's tendency to deform. Compared to this comparative solution, this solution eliminates the need for additional support components, resulting in a more streamlined and compact structure with lower costs, such as saving on mold costs for plastic support components.

[0010] In one or more embodiments of the light-emitting device, the bracket is rigid, such that the bracket maintains a shape adapted to the edge of the back plate, and the bracket is welded and / or riveted to the back plate.

[0012] In one or more embodiments of the light-emitting device, the connecting portion is disposed in the space between the bracket and the back plate; the light-emitting portion of the light-emitting strip includes a first portion and a second portion; the first portion is covered by the bracket and the back plate, and the second portion is exposed outward; and at least a portion of the second portion is disposed on the side of the light-emitting portion that extends outward along the thickness direction of the light-emitting device.

[0040] It is understood that the light-emitting device and the seat containing it provided in this application are particularly suitable for automobiles, but can also be applied to other applicable occasions, such as rail trains, ships, and aircraft, as well as applicable fixed places, such as meeting rooms, auditoriums, and cinemas, as long as there are seats and the light-emitting device disclosed in the embodiments of this application can be used, and is not limited thereto.

[0041] like Figure 3 The light-emitting device 100 shown is mounted on the backrest 110 of the seat 10 and is capable of producing a luminous visual effect. The light-emitting device 100 can be used for decoration, illumination, or to emit signals through specific visual effects, etc., and is not limited thereto. Generally, the light-emitting device 100 is also referred to as an ambient light; for example... Figures 4 to 9As shown, the light-emitting device 100 includes a light-emitting strip 1210 and a bracket 1220; the light-emitting strip 1210 includes a light-emitting portion 1211 and a connecting portion 1212 extending from the side of the light-emitting portion 1211; the connecting portion 1212 of the light-emitting strip 1210 connects to the bracket 1220, for example, the connecting portion 1212 is glued to the bracket 1220, the bracket 1220 is disposed on the edge 111 of the back plate 110, and the bracket 1220 is used to mount the light-emitting strip 1210; see also Figure 10 , Figure 11 The cross-section of the light-emitting device 100 shown shows that the connecting part 1212 of the light-emitting strip 1210 is disposed in the space between the bracket 1220 and the back plate 110; the connecting part 1212 is provided with a plurality of positioning holes 1213, and the bracket 1220 is provided with a plurality of positioning posts 1221 at positions corresponding to the plurality of positioning holes 1213, and the positioning posts 1221 pass through the positioning holes 1213 to define the installation position of the light-emitting strip 1210.

[0042] like Figure 3 As shown, back panel 110 refers to an exterior component that is generally plate-shaped (shell-shaped); back panel 110 may be an exterior component that covers the entire back of seat 10, or it may be an exterior component of a component of seat 10 (such as a chair back), or it may be an exterior component of a structure such as a table or leg rest provided on the back of seat 10, and is not limited thereto.

[0043] like Figures 4 to 9 As shown, the light-emitting strip 1210 refers to a strip-shaped (strip-shaped) component in the light-emitting device 100 that can provide a visual effect of light emission; the light-emitting strip 1210 can be an assembly unit in the light-emitting device 100, in other words, the light-emitting strip 1210 can be an integral piece that is completely mounted on the bracket 1220; the connecting part 1212 of the light-emitting strip 1210 is the part for mounting to the bracket 1220, and the light-emitting part 1211 is the part for emitting light; generally, the light-emitting part 1211 is equipped with an optical fiber for guiding light, the end of the optical fiber is connected to a light source, and the light emitted by the light source enters the optical fiber to produce a visual effect similar to the optical fiber emitting light; the light-emitting part 1211 can also Other structures, such as those equipped with LED light strips, are acceptable as long as they can produce a visual effect of light emission and are suitable for constituting the light-emitting device 100; the bracket 1220 is a component used to provide support for the light-emitting strip 1210 and to mount the light-emitting strip 1210 onto the back plate 110; the plurality of positioning holes 1213 of the connecting portion 1212 and the plurality of positioning posts 1221 of the bracket 1220 refer to corresponding recesses and protrusions, respectively. The positioning posts 1221 pass through the positioning holes 1213 to define the installation position of the light-emitting strip 1210. The positioning holes 1213 and the positioning posts 1221 can be configured as circular through holes and cylinders, and are not limited thereto.

[0044] The inventors discovered that the uneven and unsightly gaps between the light-emitting strip 1210 and components such as the bracket 1220 and back plate 110 are mainly caused by the difficulty in properly installing the light-emitting strip 1210. Since the light-emitting strip 1210 and the bracket 1220 are usually fixed with adhesive, and the light-emitting strip 1210 is generally flexible and has a slender shape, during the assembly of the light-emitting device 100, on the one hand, the light-emitting strip 1210 is prone to deviating from its installation position; on the other hand, it is difficult to ensure the quality of the adhesive bonding of the light-emitting strip 1210 to the bracket 1220 (especially under manual operation), resulting in the light-emitting strip 1210 shifting, developing wavy wrinkles, etc., thus causing uneven and unsightly gaps. By adjusting the bracket... Positioning posts 1221 are provided in the bracket 1220, and positioning holes 1213 are provided in the connecting part 1212 of the light-emitting strip 1210. During the assembly of the light-emitting device 100, the positioning posts 1221 can be inserted into the positioning holes 1213 first, so that the light-emitting strip 1210 is roughly limited to its installation position. This helps to ensure that the light-emitting strip 1210 is installed in place, reduces the difficulty of gluing, and improves the assembly quality. Moreover, after the assembly is completed, the positioning posts 1221 and positioning holes 1213 can still play the role of fixing the position of the light-emitting strip 1210. Compared with the comparative solution of fixing the bracket 1220 and the light-emitting strip 1210 by gluing alone, the use of positioning posts 1221 and positioning holes 1213 makes the connection more stable and reliable. In addition, some comparative solutions add support components, such as rigid plastic parts, to the light-emitting strip 1210 to improve the rigidity of the light-emitting strip. By changing the deformable characteristics of the light-emitting strip 1210, the problem of uneven gaps and unsightly appearance is improved. Compared with the comparative solution, this solution does not require the addition of support components, so the structure is more streamlined, which is conducive to compactness and lower cost, such as saving the mold cost of support components.

[0045] like Figure 3 As shown, the upper side and the left and right edges 111 of the back panel 110 can also be configured as first flanges, thereby forming a curved panel (shell) to cover other components located inside it; the bracket 1220 can also fit against the inner surface of the first flange (i.e., the surface of the recessed side), so that the bracket 1220 is generally located inside the back panel 110 and is not easily seen by the user, thus making the design more aesthetically pleasing. Figure 10 , Figure 11 As shown, the bracket 1220 may also be provided with a second flange 1229, which covers at least a portion of the end face 117 of the edge 111; the light-emitting strip 1210 may also be configured such that the fixed position of the light-emitting part 1211 is further defined by the second flange 1229 and the end face 117 of the edge 111 of the back plate, thereby defining the fixed position of the light-emitting strip 1210.

[0046] like Figure 5As shown, in one or more embodiments, the bracket 1220 is configured to be rigid, also referred to as a rigid bracket, which is capable of maintaining a shape adapted to the edge 111 of the back plate 110. In other words, the bracket 1220 is rigid and not easily deformed, and has a fixed shape conforming to the edge 111 of the back plate 110 to fit the edge 111 of the back plate 110; and the bracket 1220 is welded and / or riveted to the back plate 110.

[0047] Existing brackets can be broadly classified into two types: rigid brackets and flexible brackets. As mentioned above, rigid brackets are more flexible and easily deformable, capable of bending along the edge 111 of the back plate 110 to fit the edge 111 of the back plate 110. Compared to the comparative scheme using flexible brackets, using rigid brackets makes the entire light-emitting device 100 more rigid. The bracket 1220 provides stronger support for the light-emitting strip 1210, which is more conducive to improving the uneven and unsightly installation gap of the light-emitting strip 1210. Furthermore, rigid brackets are generally less prone to stretching and deformation after riveting and welding, ensuring a beautiful visual effect. Compared to some comparative schemes where the bracket 1220a and the back plate 110a are fixed by adhesive bonding, riveting and / or welding replace adhesive bonding, thereby reducing the amount of adhesive used, improving odor, shortening the assembly cycle, and ensuring stable, reliable, and high-strength connections. It is understood that the concepts of flexible and rigid supports mentioned above are relative, not absolute. Flexibility means that when subjected to external force, its shape will undergo a deformation that is visible to the naked eye. The materials of flexible supports can be, for example, silicone, rubber, foam, etc. In contrast, rigid components mean that when subjected to external force, their shape will not undergo a deformation that is visible to the naked eye. The materials of rigid supports can be, for example, plastics, such as PP plastic, engineering plastics, etc.

[0048] like Figure 3 , Figure 5 As shown, in one or more embodiments, the back plate 110 and the bracket 1220 are plastic parts; and the bracket 1220 includes an upper part 1222 and two side parts 1223; wherein, the upper part 1222 is provided with a plurality of riveting portions 1224, and the riveting portions 1224 refer to the parts where rivet holes 1225 are opened; as Figure 5As shown, the riveting part 1224 can be a boss extending from the bracket 1220 to provide the opening position of the rivet hole 1225 and ensure structural strength, but is not limited thereto; the upper edge of the back plate 110 is provided with a plurality of hot melt pillars 112 at positions corresponding to a plurality of riveting parts 1224. The hot melt pillars 112 penetrate into the rivet holes 1225 of the riveting part 1224, and the hot melt pillars 112 are formed into rivet heads by hot riveting, so that the upper part 1222 is riveted to the upper edge of the back plate 110; the two side parts 1223 are respectively provided with a plurality of welding parts 1226. The welding parts 1226 refer to the parts that are defined for piercing welding. The welding parts 1226 have appropriate dimensions, material properties, etc. to meet the process requirements of piercing welding. The welding parts 1226 of the two side parts 1223 are respectively pierced and welded to the left edge and the right edge of the back plate 110.

[0049] It can be understood that riveting is used between the upper part 1222 and the upper edge of the back plate 110, while welding is used between the two side parts 1223 and the left and right side edges of the back plate 110. To ensure good connection strength, only a number of hot-melt pillars 112 extending from the upper edge of the back plate 110 and a number of riveting portions 1224 extending from the upper part 1222 of the bracket 1220 are needed. There is no need for protrusions extending from the left and right sides, so that the hot-melt pillars 112 (and riveting portions 1224) with protruding features extend approximately in a single direction. The extension design prevents the back panel 110 and the bracket 1220 from extending in multiple directions, which would prevent them from being completely demolded. This allows the back panel 110 and the bracket 1220 to be integrally molded without the need for separate assembly, thus ensuring the structural strength of the bracket 1220 and the back panel, reducing costs, and shortening the manufacturing cycle. The riveting process compresses the back panel 110 and the bracket 1220, resulting in a small matching gap between them, which helps to avoid problems such as shaking and abnormal noise. Furthermore, hot riveting and piercing welding processes are relatively mature in the automotive seat industry, which helps to ensure manufacturing quality and cycle time. It is understood that, while ensuring integral fabrication, fewer rivetings can be used between the side portion 1223 of the bracket 1220 and the left and right edges of the back plate 110. For example, in some embodiments, a riveting is used at the end of each side portion 1223 away from the upper portion 1222. The hot-melt column extends in an appropriate direction so that the back plate 110 and the bracket 1220 can still be integrally fabricated, and the matching gap between the back plate 110 and the bracket 1220 on the left and right sides is small, avoiding problems such as shaking and abnormal noise. This is not a limitation.

[0050] like Figure 11As shown, in one or more embodiments, the light-emitting portion 1211 of the light-emitting strip 1210 includes a first portion 1214 and a second portion 1215; the first portion 1214 is covered by the bracket 1220 and the back plate 110, and the second portion 1215 is exposed outward; in other words, at least a portion of the light-emitting portion 1211 is configured as the second portion 1215, the second portion 1215 is in direct contact with the outside and can be seen by the user; and at least a portion of the second portion 1215 is disposed on the side of the light-emitting portion 1211 that extends outward along the thickness direction of the light-emitting device 100 (the appearance side).

[0051] See Figure 1 The cross-section of the light-emitting device 100a in some comparative schemes shown has components (first component 103a, second component 104a) arranged on both sides of the light-emitting strip 102a, thereby forming a fully enclosed structure that accommodates the light-emitting strip 102a. The outer side of this fully enclosed structure is also covered by a back plate 101a, resulting in a relatively thick overall thickness H' of the light-emitting device 100a in the comparative scheme, for example, a thickness H' of approximately 11 mm; while the light-emitting device 100a in this scheme, such as Figure 10 , Figure 11 As shown, without the need for a fully enclosed structure similar to the comparative scheme, the connecting part 1212 extends into the space between the bracket 1220 and the back plate 110. The bracket 1220 and the back plate 110 only cover the first part 1214 of the light-emitting part 1211, while the second part 1215 is directly exposed to the outside. No other components are provided on the outside of the second part 1215. Compared with the light-emitting device 100a of the comparative scheme, it is more concise. In particular, at least a portion of the second part 1215 is provided on one side along the thickness direction of the light-emitting device 100, which effectively achieves a thinner thickness H of the light-emitting device 100, for example, a thickness H of about 7 mm.

[0052] like Figure 10 , Figure 11 As shown, in one or more embodiments, the bracket 1220 has a first groove 1227 adapted to the first part 1214 at a position corresponding to the first part 1214, so that the first groove 1227 fits against the first part 1214; and / or, the back plate 110 has a second groove 113 adapted to the first part 1214 at a position corresponding to the first part 1214, so that the second groove 113 fits against the first part 1214. The design of the first groove 1227 and / or the second groove 113 can further ensure that the light-emitting strip 1210 (light-emitting part 1211) is in its fixed position.

[0053] like Figure 10 , Figure 11As shown, in one or more embodiments, the thickness h1 of the support 1220 is in the range of 2 mm to 3 mm; and the thickness H of the light-emitting device 100 is in the range of 5 mm to 9 mm. Alternatively, when the back plate 110 includes a substrate 114 and a covering layer 115 covering the outside of the substrate 114, the sum of the thickness h1 of the support 1220 and the thickness h2 of the substrate 114 is in the range of 5 mm to 9 mm. It can be understood that the back plate 110 is a plate-shaped (shell-shaped) component with a significantly small thickness, and the support 1220 is a generally elongated component with a length and width defined by a narrow surface and a significantly small thickness h1; the thickness of the light-emitting device 100 mentioned here refers to the thickness dimension defined by the back plate 110, the support 1220, and the light-emitting strip 1210, and the direction of the thickness H of the light-emitting device 100 can be determined to be approximately the same as the thickness direction of the back plate 110; for the portion of the light-emitting device 100 where the support 1220 and the light-emitting strip 1210 extend beyond the end face 117 of the back plate 110, the thickness direction of this portion of the light-emitting device 100 can also be determined to be approximately the same as the thickness direction of the back plate 110 at the end face 117; it can be understood that, in such Figure 10 , Figure 11 In some embodiments shown, the surface of the bracket 1220 is generally attached to the surface of the edge 111 of the back plate 110, and the influence of the light-emitting strip 1210 on the thickness H of the light-emitting device 100 is negligible. In particular, the connecting part 1212 can be configured as a flexible strip structure with negligible thickness. Therefore, the thickness of the light-emitting device 100 mainly includes the thickness h1 of the bracket 1220 and the thickness of the back plate 110. By limiting the thickness of the bracket 1220 to the range of 2 mm to 3 mm and the thickness H of the light-emitting device 100 to the range of 5 mm to 9 mm, it is beneficial to save space in the thickness direction while ensuring the strength and other characteristics of the light-emitting device 100, so that its interior can provide a larger accommodating space and realize the compactness of the light-emitting device 100.

[0054] like Figure 11As shown, in some embodiments, the back plate 110 is composed of a substrate 114 and a covering layer 115. The substrate 114 refers to the part that serves as a support member, which has appropriate strength and other characteristics to meet the needs of supporting the load. The covering layer 115 refers to the part that serves as a decorative member, such as being made of leather or other materials, which covers the surface of the substrate 114 to give the back plate 110 a better texture and make it more aesthetically pleasing. Furthermore, the covering layer 115 usually has an inwardly folded edge 116 at the edge 111 of the back plate 110, covering the inner surface of the substrate 114. It can be understood that since the thickness of the covering layer 115 is usually determined according to individual needs, it has a large range of options, which causes the covering layer 115 and its edge 116 to significantly affect the thickness H of the entire light-emitting device 100. Therefore, for the case where the back plate 110 is provided with a covering layer 115, the sum of the thicknesses of the support 1220 and the substrate 114 is limited to the range of 5 mm to 9 mm, so as to achieve the compactness of the light-emitting device 100 while meeting the support load requirements.

[0055] like Figure 6 As shown, in one or more embodiments, the light-emitting strip 1210 is flexible, allowing it to deform with the shape of the bracket 1220. A plurality of tension ribs 1228 are provided on the surface of the bracket 1220 at positions corresponding to the connecting portion 1212. The tension ribs 1228 abut against the connecting portion 1212, causing the light-emitting strip 1210 to be tensioned, thereby preventing wrinkles and ensuring the fixed position of the light-emitting strip 1210, resulting in a more aesthetically pleasing appearance. Furthermore, the tension ribs 1228 also help to enhance the local rigidity of the bracket 1220.

[0056] like Figure 2 The seat 10 shown has a light-emitting device 100 as described above on its back. The light-emitting device 100 is configured as an exterior component of the seat 10, and the light-emitting visual effect produced by the light-emitting strip 1210 can be seen by the user from the outside.

[0057] In one or more embodiments, the seat 10 is provided with a control device that extends through the bracket 1220 into the interior of the seat 10; the bracket 1220 is a rigid bracket 1220 and has a narrow section with a reduced width to avoid the control device; the control device referred to herein refers to control buttons, knobs, control panels, etc., provided on the seat 10, but is not limited thereto; the narrow section referred to herein is, for example, an opening extending from the side to the middle along the width direction, or a through structure opened in the middle, etc., but is not limited thereto; it is understood that some comparative solutions use a flexible bracket and have similar narrow sections on the flexible bracket. Since the flexible bracket is more prone to stretching, bending and other deformations than the rigid bracket, its narrow section is more easily damaged, while using a rigid bracket is relatively more conducive to ensuring the strength of the narrow section.

[0058] like Figure 2 The vehicle 1 shown is, for example, an automobile, which includes the seat 10 described above.

[0059] To more clearly describe this application, a method for manufacturing the light-emitting device 100 and the seat 10 according to some embodiments is provided, including:

[0060] S1. Assemble the light-emitting strip 1210 and the bracket 1220 into a light-emitting device 100;

[0061] S2. Install the light-emitting device 100 onto the edge 111 of the back plate 110; wherein...

[0062] Step S1 may specifically include:

[0063] S11. Insert the positioning post 1221 of the bracket 1220 into the positioning hole 1213 of the light-emitting strip 1210 to limit the fixed position of the light-emitting strip 1210.

[0064] S12. Glue the light-emitting strip 1210 to the bracket 1220;

[0065] Step S2 may specifically include:

[0066] S21. Rivet and / or weld the bracket 1220 to the edge 111 of the back plate 110.

[0067] By using the above method, the fixed position of the light-emitting strip 1210 is first defined by the positioning post 1221 and the positioning hole 1213, and then the light-emitting strip 1210 and the bracket 1220 are glued together. This ensures that the light-emitting strip 1210 is assembled in place, improves the assembly quality, avoids problems such as uneven installation gaps and wrinkles of the light-emitting strip 1210, makes the product more aesthetically pleasing, reduces the difficulty of operation, and makes the connection effect more stable and reliable. Compared with the glued method, the method of riveting and / or welding to connect the bracket 1220 and the back plate 110 reduces the amount of adhesive used, has a good odor, strong applicability, and high mass production stability.

[0068] In summary, the advanced technical effects of this application include, but are not limited to, at least one of the following:

[0069] By setting positioning posts on the bracket and positioning holes at the connection of the light-emitting strip, the positioning posts can be inserted into the positioning holes during the assembly of the light-emitting device, thus roughly defining the installation position of the light-emitting strip. This facilitates proper installation of the light-emitting strip, reduces the difficulty of gluing, and improves installation quality. Furthermore, after assembly, the positioning posts and positioning holes still serve to fix the position of the light-emitting strip. Compared to the solution of simply gluing the bracket and the light-emitting strip together, the use of positioning posts and positioning holes makes the connection more stable and reliable. In addition, some comparative solutions add support components to the light-emitting strip, such as rigid plastic parts, to increase the rigidity of the light-emitting strip. By changing the easy deformation characteristics of the light-emitting strip, the problem of uneven installation gaps and unsightly appearance of the light-emitting strip can be improved. Compared to this comparative solution, this solution does not require additional support components, resulting in a more streamlined and compact structure with lower costs, such as saving on the mold costs of plastic support components.

[0070] While this application discloses preferred embodiments as described above, it is not intended to limit the scope of this application. Any changes and modifications can be made by those skilled in the art without departing from the spirit and scope of this application. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application, without departing from the content of the technical solution of this application, fall within the protection scope defined by the claims of this application.
