Technical Field
[0001] This application relates to the field of automotive lighting technology, and in particular to a connection structure for automotive lighting components and an automotive lighting system. Background Technology
[0002] Some components of automotive lights are bonded with adhesives. Adhesive bonding is beneficial for the lightweighting of automotive lights. For automobiles, lightweighting means higher energy efficiency and better performance. Moreover, adhesive bonding is suitable for parts of various shapes and sizes, and is not limited by specific geometries, thus having high flexibility. Therefore, adhesive bonding is a preferred connection method for automotive light components.
[0003] However, current car lights are bonded together by applying adhesive over a large area between the two light components. If the light malfunctions and the two bonded light components need to be separated for repair, the light components will be damaged. Since light components are usually non-standard parts, it is difficult to find replacement parts once they are damaged.
[0004] Therefore, how to separate the bonded automotive headlight components without damage is a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] To solve the above-mentioned technical problems, this application provides a connection structure for a vehicle lamp component, including a first component and a second component. The first component includes a first body with a through hole. The second component includes a second body and a connecting post. There is a gap between the first body and the second body. The connecting post protrudes from the second body toward the first body and is at least partially inserted into the through hole. A glue-blocking portion is provided between the first body and the second body. The glue-blocking portion surrounds the outside of the connecting post. An adhesive cavity is formed between the inner side of the glue-blocking portion and the sidewall of the through hole and the outer side of the connecting post. The glue-blocking portion separates the adhesive cavity from the gap. The adhesive cavity is filled with adhesive, and the adhesive bonds the first component and the second component.
[0006] In one embodiment of the connection structure of the vehicle headlight component, the rubber baffle is integrally formed with one of the first body or the second body, and one end of the rubber baffle abuts against the other of the first body or the second body.
[0007] One embodiment of the connection structure of a vehicle headlight component includes a cover, the cover including a cover body, the cover being fixedly connected to a first component and / or a second component, the cover body covering one end of the adhesive cavity away from the second component.
[0008] One embodiment of the connection structure of the vehicle headlight component includes a cover with a connecting part, which is inserted into the rubber cavity and fixedly connected to the connecting post. A limiting step surface is provided on the side wall of the through hole, and the cover body abuts against the limiting step surface.
[0009] In one embodiment of the connection structure of the vehicle headlight component, the cover body has a groove on the side near the limiting step surface.
[0010] One embodiment of the connection structure for a vehicle headlight component has a gap between the cover body and the side wall of the through hole.
[0011] One embodiment of the connection structure for vehicle headlight components is that the connecting part is fixed by snap-fitting or by threaded connection with the connecting post.
[0012] In one embodiment of the connection structure of the vehicle headlight component, a plurality of snap-fit protrusions are arranged sequentially along the circumferential direction on the outer side of the connecting post. The end of the snap-fit protrusion away from the limiting step surface is provided with a locking step surface. The connecting part includes a plurality of snap-fit sleeves arranged sequentially along the circumferential direction. The snap-fit protrusions are snapped into the inner hole of the snap-fit sleeves, and the locking step surface abuts against the side wall of the inner hole of the snap-fit sleeve.
[0013] In one embodiment of the connection structure of the vehicle headlight component, the end of the snap-fit protrusion near the limiting step surface is provided with a guide slope, and the end of the guide slope near the limiting step surface is inclined towards the central axis of the connecting post relative to the end away from the limiting step surface.
[0014] This application also provides a vehicle lamp, wherein at least two components of the vehicle lamp are connected using the connection structure described in any one of the above claims.
[0015] The connection structure for the vehicle headlight component provided in this application has a gap between the first and second components, and this gap is separated from the adhesive cavity constructed to accommodate the adhesive by an adhesive-blocking part. Therefore, after the adhesive is poured into the adhesive cavity, the adhesive remains only in the adhesive cavity and does not spread into the gap between the first and second components. When separating the first and second components, a hot air gun can be used to heat the adhesive in the adhesive cavity from the end of the adhesive cavity away from the second component to melt the adhesive in the adhesive cavity. Since the adhesive remains only in the adhesive cavity, the first and second components can be separated as long as the adhesive in the adhesive cavity melts. Since the end of the adhesive cavity away from the second component is not blocked by the first or second component, when the hot air gun is used to heat the adhesive in the adhesive cavity, the heat of the hot air gun can act directly on the adhesive in the adhesive cavity without passing through the first and second components. Therefore, it will not cause thermal deformation or damage to the first and second components. Thus, the bonded first and second components can be separated without damaging the first and second components. Attached Figure Description

Detailed Implementation
[0024] To enable those skilled in the art to better understand the technical solution of this application, the technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] like Figures 1-6 As shown, the connection structure provided in this application includes a first component 100 and a second component 200.
[0026] The first component 100 includes a first body 101, which has a through hole 101a. Specifically, the through hole 101a extends from the side of the first body 101 away from the second component 200 to the side of the first body 101 close to the second component 200.
[0027] The second component 200 includes a second body 201 and a connecting post 202. The connecting post 202 protrudes from the second body 201 toward the first body 101, and the connecting post 202 is at least partially inserted into the through hole 101a. Specifically, the outer diameter of the connecting post 202 is smaller than the inner diameter of the through hole 101a.
[0028] A gap X exists between the first body 101 and the second body 201. A sealant portion 102 is provided between the first body 101 and the second body 201. The sealant portion 102 surrounds the outside of the connecting post 202, and the inner diameter of the sealant portion 102 is larger than the outer diameter of the connecting post 202. An adhesive cavity is formed between the inner surface of the sealant portion 102 and the outer surface of the connecting post 202, and between the sidewall of the through hole 101a and the outer surface of the connecting post 202. The sealant portion 102 separates the adhesive cavity from the gap X. The adhesive cavity is filled with adhesive, which bonds the first component 100 and the second component 200.
[0029] In the above-mentioned connection structure of the vehicle lamp components, since there is a gap X between the first component 100 and the second component 200, and the gap X is separated from the glue cavity for containing adhesive by the glue-blocking part 102, after the adhesive is poured into the glue cavity, the adhesive will only remain in the glue cavity and will not spread to the gap X between the first component 100 and the second component 200. When separating the first component 100 and the second component 200, a hot air gun can be used to heat the adhesive in the glue cavity from the end away from the second component 200 to melt the adhesive. Since the adhesive remains only in the glue cavity, the first component 100 and the second component 200 can be separated once the adhesive in the glue cavity melts. Since the end of the glue cavity away from the second component 200 is not blocked by the first component 100 or the second component 200, the heat from the hot air gun can act directly on the adhesive in the glue cavity without passing through the first component 100 and the second component 200 when heating the adhesive in the glue cavity. Therefore, it will not cause thermal deformation or damage to the first component 100 and the second component 200.
[0030] If there is adhesive in the gap X between the first component 100 and the second component 200, then the adhesive in the gap X needs to be melted in order to separate the first component 100 and the second component 200. However, to melt the adhesive in the gap X, the heat of the hot air gun needs to pass through the first component 100 and the second component 200 to act on the adhesive in the gap X. This will cause the first component 100 and the second component 200 to be damaged by heat deformation. In this application, because the adhesive blocking part 102 separates the adhesive cavity from the gap X, the adhesive is prevented from spreading into the gap X between the first component 100 and the second component 200.
[0031] In some embodiments, such as Figure 6 As shown, the adhesive-blocking part 102 is integral with the first body 101. One end of the adhesive-blocking part 102 abuts against the second body 201. More specifically, the adhesive-blocking part 102 protrudes from the side of the first body 101 near the second body 201 toward the second body 201, and the adhesive-blocking part 102 abuts against the side of the second body 201 near the first body 101.
[0032] Alternatively, the adhesive-blocking part 102 can be integrated with the second body 201, with one end of the adhesive-blocking part 102 abutting against the first body 101. More specifically, the adhesive-blocking part 102 protrudes from the side of the second body 201 near the first body 101 toward the first body 101, and the adhesive-blocking part 102 abuts against the side of the first body 101 near the second body 201.
[0033] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the connection structure provided in this application also includes a cover 300, which includes a cover body 301. The cover 300 is fixedly connected to the first component 100 and / or the second component 200, and the cover body 301 covers the end of the adhesive cavity away from the second component 200. This design allows the cover body 301 to cover the adhesive inside the adhesive cavity, preventing the adhesive from being exposed and affecting the quality of the headlight. When it is necessary to separate the first component 100 and the second component 200, the cover 300 is first removed, and then a heat gun is used to heat the adhesive inside the adhesive cavity from the end away from the second component 200.
[0034] In some embodiments, such as Figure 6 As shown, the cover 300 includes a connecting part 302, which is inserted into the receiving cavity and fixedly connected to the connecting post 202. A limiting step surface A is provided on the side wall of the through hole 101a, and the cover body 301 abuts against the limiting step surface A. This design not only achieves the installation and fixation of the cover 300, but also limits the relative position of the first component 100 and the second component 200, avoiding misalignment of the first component 100 and the second component 200 when the adhesive is moved before it has hardened (for example, when the adhesive needs to be moved from the glue injection station to another station before it has hardened).
[0035] In some embodiments, such as Figure 6 As shown, the outer diameter of the cover body 301 is smaller than the inner diameter of the corresponding part of the through hole 101a, resulting in a gap Y between the cover body 301 and the side wall of the through hole 101a. This allows the disassembly tool to pry the cover 300 through this gap Y during disassembly, facilitating removal. The cover 300 can be designed as a standard part, so if it is damaged during disassembly, a new cover 300 can be replaced.
[0036] In some embodiments, such as Figure 6As shown, the connecting part 302 and the connecting post 202 are engaged and fixed along the axial direction of the connecting post 202. Specifically, in the illustrated embodiment, a plurality of engaging protrusions 202a are arranged at intervals along the circumferential direction on the outer side of the connecting post 202. The end of the engaging protrusion 202a away from the limiting step surface A is provided with a locking step surface B, which faces the second component 200. The connecting part 302 includes a plurality of engaging sleeves 302a arranged at intervals along the circumferential direction (see...). Figure 5 The engaging protrusion 202a engages with the inner hole of the engaging sleeve 302a, and the engaging step surface B abuts against the inner hole sidewall of the engaging sleeve 302a. Additionally, in the illustrated embodiment, the end of the engaging protrusion 202a near the limiting step surface A is provided with a guide slope C (see...). Figure 4 The guide slope C, with its end near the limiting step surface A, is inclined away from the central axis of the connecting post 202 relative to the end away from the limiting step surface A. This allows the snap-fit sleeve 302a to easily snap into the snap-fit protrusion 202a along the guide slope C. This snap-fit structure in the illustrated embodiment is relatively easy to manufacture and provides good snap-fit strength. However, in actual implementation, the snap-fit structure between the connecting part 302 and the connecting post 202 is not limited to the structure shown in the illustrated embodiment.
[0037] Alternatively, in addition to snap-fit fixing, the connecting part 302 and the connecting post 202 can also be fixed by other methods, such as threaded fixing.
[0038] In some embodiments, such as Figure 6 As shown, the cover body 301 has a groove 301a on the side near the limiting step surface A. In this way, when the connecting part 302 of the cover 300 is inserted into the glue cavity, the overflowing glue can enter the groove 301a, providing space for the overflowing glue and increasing the connection between the cover body 301 and the limiting step surface A.
[0039] At least two components of the vehicle light provided in this application are connected using the above-described connection structure.
[0040] In some embodiments, at least two injection-molded components of the headlight are connected using the connection structure described above.
[0041] In some embodiments, the headlight includes a frame and a thick wall, which are connected by the connection structure described above.
[0042] In some embodiments, the vehicle light includes a bracket, a light-blocking plate, and a thick wall, wherein the bracket and the light-blocking plate are connected by the above-described connection structure and / or the light-blocking plate and the thick wall are connected by the above-described connection structure.
[0043] The above embodiments can be freely combined without conflict.
[0044] The above examples illustrate the principles and implementation methods of this application. The descriptions of the embodiments are merely for the purpose of helping to understand the methods and core ideas of this application.
