[0002] As a key structure for safe driving, vehicle lights not only provide illumination in dark environments but also guide functions such as lane changes. Their performance directly affects driving safety, so improving the quality of vehicle lights has become a key focus of industry research.

[0003] Currently, existing automotive headlights on the market, such as the high-sealing automotive taillight disclosed in patent CN222543661U, improve the headlight's sealing performance to prevent rainwater and other substances from entering the headlight and affecting its safety. This headlight includes a fixed frame, a protective net, and a lampshade. The protective net is fixedly connected to one side of the fixed frame and is designed as a frame structure. The lampshade is fixedly connected to the inside of the protective net. Additionally, the fixed frame has a sealing structure for sealing the interior of the headlight. This sealing structure includes a connecting ring fixedly connected to the inside of the fixed frame, and a sealing ring is fixedly connected to the inside of the connecting ring. During use, if the headlight is subjected to vibration, causing the connecting screws to loosen and weaken their restraining effect, a gap may appear between the sealing ring and the sealing plate. This gap can be filled by a compressed elastic sealing strip between the sealing plate and the connecting ring, thus maintaining the headlight's internal sealing performance. Although the aforementioned headlights can improve sealing performance, they rely on connecting screws to connect the fixing frame and the sealing plate. Furthermore, multiple connecting screws are required to work simultaneously, resulting in multiple connection holes between the fixing frame and the sealing plate, affecting structural strength and aesthetics. In addition, because the tightening force of each connecting screw cannot be completely consistent, the pressure on the sealing strip varies at different connection points, leading to inconsistent sealing effects and affecting the overall sealing performance. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, the aim is to provide a vehicle lamp with high sealing performance. This lamp features ultrasonic welding sections on both the lamp cover and the base, enabling ultrasonic welding between the base and the lamp cover. This ensures consistent connection strength across all parts and allows for seamless welding, guaranteeing sealing performance. It also avoids the aesthetic issues associated with connecting screws, thus improving the overall quality of the vehicle lamp.

[0005] The specific technical solution is as follows: A highly sealed vehicle lamp includes a base, a lamp cover, and a light assembly. The lamp cover is placed on the base, and the light assembly is disposed within the structure formed by the base and the lamp cover. The lamp lamp has the following features: a first welding part and a second welding part are respectively provided on opposite sides of the base and the lamp cover. The first welding part surrounds the outer edge of the base, and the second welding part surrounds the outer edge of the lamp cover. The first welding part and the second welding part are arranged opposite to each other and fit together. Furthermore, the first welding part and the second welding part are ultrasonically welded.

[0006] In the aforementioned high-sealing vehicle light, a slot is provided on the outer edge of the base facing the lamp cover, with the slot opening facing the lamp cover. Meanwhile, an extended insert is provided on the outer edge of the lamp cover facing the base, and the insert is inserted into the slot when the lamp cover is installed on the base.

[0007] In the aforementioned high-sealing vehicle lamp, a retaining edge is provided around the lamp cover and on the outside of the insert edge, and a gap is provided between the end face of the retaining edge and the insert edge along the direction from the lamp cover to the lamp holder. The retaining edge is used as a second welding part, and the outer groove edge of the slot is used as a first welding part.

[0008] In the aforementioned high-sealing vehicle light, a plurality of abutment blocks are provided on the outer wall of the insert edge. The abutment blocks are evenly distributed and spaced around the insert edge. When the insert edge is inserted into the slot, the insert edge abuts against the inner wall of the slot through the abutment blocks.

[0009] The aforementioned high-sealing vehicle light also includes a sealing strip, which is disposed in a slot and located between the insertion edge and the inner wall of the slot.

[0010] The aforementioned high-sealing vehicle light also includes an adhesive, which is disposed in a slot and contacts the slot edge after the insertion edge is inserted into the slot.

[0011] In the aforementioned high-sealing vehicle lamp, the outer wall of the end into which the insert is inserted is inclined, and the inclination direction is towards the inside of the lamp cover.

[0012] In the aforementioned high-sealing vehicle lamp, a plurality of guide grooves corresponding to the abutment blocks are provided on the inner wall of the slot along the direction from the lamp cover to the base.

[0016] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0017] Figure 1 This is a structural diagram of an embodiment of a high-sealing vehicle lamp according to the present invention; Figure 2 This is a cross-sectional view of an embodiment of a highly sealed vehicle lamp according to this utility model. Figure 1 and Figure 2As shown, the high-sealing vehicle lamp provided in this embodiment includes: a base 1, a lamp cover 2, and a light assembly 3. The lamp cover 2 covers the base 1, and the light assembly 3 is disposed within the structure formed by the base 1 and the lamp cover 2, meeting the light emission requirements of a normal vehicle lamp. Simultaneously, the combined structure of the lamp cover 2 and the base 1 provides external protection for the light assembly 3, ensuring safe use and extending its service life. It is worth noting that the light assembly 3 includes, but is not limited to, LED lights, lamp brackets, and diffuser covers. Since most vehicle lamps on the market have a light assembly 3, the light assembly 3 involved in this embodiment can be selected from existing light assemblies and used directly. Therefore, the specific structure of the light assembly 3 in this embodiment will not be described in detail here.

[0018] Specifically, a first welding part 11 and a second welding part 21 are respectively provided on the opposite sides of the base 1 and the lamp cover 2. The first welding part 11 surrounds the outer edge of the base 1, and the second welding part 21 surrounds the outer edge of the lamp cover 2, ensuring that the first welding part 11 and the second welding part 21 can completely cover the connection part of the base 1 and the lamp cover 2, providing conditions for subsequent seamless welding to ensure sealing. At this time, the first welding part 11 and the second welding part 21 are arranged opposite to each other and fit together. Furthermore, the first welding part 11 and the second welding part 21 are ultrasonically welded, that is, the ultrasonic welding of the first welding part 11 and the second welding part 21 forms a ring of ultrasonic weld structure at the connection between the base 1 and the lamp cover 2, completely covering the gap at the connection between the base 1 and the lamp cover 2, ensuring the sealing performance of the vehicle lamp. At the same time, it also avoids the problem of needing to process connection holes when using connecting screws, which affects the structural strength and aesthetics, thus improving the quality of the vehicle lamp.

[0019] More specifically, a slot 12 is provided on the outer edge of the base 1 facing the lampshade 2, and the opening of the slot 12 is arranged facing the lampshade 2, providing a condition for the lampshade 2 to be inserted into the slot 12 to connect the lampshade 2 to the base 1. At the same time, an extended insertion edge 22 is provided on the outer edge of the lampshade 2 facing the base 1, so that when the lampshade 2 is installed on the base 1, it can be inserted into the slot 12 through the insertion edge 22 to achieve accurate positioning and temporary connection between the two, providing a condition for subsequent stable welding of the first welding part 11 and the second welding part 21.

[0020] More specifically, a retaining edge 23 is provided around the lamp cover 2 and outside the insert edge 22. A gap is provided between the end faces of the retaining edge 23 and the insert edge 22 along the direction from the lamp cover 2 to the lamp holder, ensuring that the insert edge 22 has a large stroke to insert into the slot 12. Preferably, the retaining edge 23 and the insert edge 22 are an integral structure, resulting in higher structural strength and a more reliable overall structure of the vehicle lamp after subsequent connection to the base 1 via the retaining edge 23. In this case, the retaining edge 23 serves as the second welding part 21, and the outer groove edge of the slot 12 serves as the first welding part 11. This allows for quick positioning of the assembly position and improves processing efficiency when connecting the lamp cover 2 to the base 1, as the insert edge 22 is inserted into the slot 12 and the retaining edge 23 abuts against the outer groove edge of the slot 12.

[0021] Figure 3 This is a structural diagram of a high-sealing vehicle lamp cover according to the present invention. Figure 2 and Figure 3 As shown, several abutment blocks 24 are also provided on the outer wall of the insertion edge 22. These abutment blocks 24 are evenly distributed and spaced around the insertion edge 22. When the insertion edge 22 is inserted into the slot 12, the insertion edge 22 abuts against the inner wall of the slot 12 through the abutment blocks 24, allowing the insertion edge 22 and the slot 12 to abut against each other through the abutment blocks 24. At this time, the abutment blocks 24 and the inner wall of the slot 12 have an interference fit. This not only meets the requirement of temporarily fixing the lampshade 2 to the base 1, but also reduces the contact area of ​​the interference fit between the insertion edge 22 and the slot 12, reducing the assembly force during installation, making assembly more time-saving and labor-saving, and also reducing the material used for the insertion edge 22, thus lowering manufacturing costs. It is worth noting that the abutment blocks 24 and the insertion edge 22 are an integral structure, resulting in higher structural strength and allowing for direct injection molding, making processing more convenient.

[0022] More specifically, a sealing strip 4 is also provided inside the slot 12, which provides installation space for the sealing strip 4. At this time, the sealing strip 4 is located between the insertion edge 22 and the inner wall of the slot 12. That is, the sealing strip 4 fills the connection gap between the insertion edge 22 of the lamp cover 2 and the slot 12 of the base 1, further improving the sealing performance at the connection between the lamp cover 2 and the base 1. This prevents the welding structure formed by the first welding part 11 and the second welding part 21 after ultrasonic welding from accidentally developing cracks after long-term use. The sealing strip 4 can still ensure the sealing effect, achieving multiple seals and further improving the sealing performance, thus ensuring the quality of the vehicle lamp.

[0023] More specifically, adhesive 5 is also provided inside the slot 12. After the insertion edge 22 is inserted into the slot 12, the adhesive 5 contacts the insertion edge 22, thus bonding the insertion edge 22 into the slot 12. This further ensures the connection strength and reliability by bonding the insertion edge 22 to the slot 12. Additionally, the adhesive 5 provides a seal, further improving the product's sealing performance. It is worth noting that the adhesive 5 includes, but is not limited to, commercially available silicone sealant (commonly known as glass glue) and other soft adhesives. While ensuring bonding strength, it also guarantees flexible deformation capability, adapting to the vibration environment during vehicle operation, resulting in a more rational structural design.

[0024] More specifically, the outer wall of the end of the insert 22 that is inserted into the slot 12 is inclined, and the inclination direction is towards the inside of the lampshade 2. This allows the outer wall of the end of the insert 22 that is inserted into the slot 12 to form an inwardly recessed guide surface. This allows the insert 22 to be quickly inserted into the slot 12 by the guide surface when the lampshade 2 is installed on the base 1, thus facilitating the connection between the two.

[0025] More specifically, several guide grooves corresponding to the abutment blocks 24 are formed on the inner wall of the slot 12 along the direction from the lampshade 2 to the base 1. This allows the insert 22 to be guided by the abutment blocks 24 when it is inserted into the slot 12, preventing relative twisting of the lampshade 2 and base 1 during assembly and avoiding excessive pressure damage to the insert 22 and slot 12, thus ensuring product quality. It is worth noting that the depth of the guide groove is less than the protruding thickness of the abutment block 24. This ensures that the guide groove can guide the abutment block 24 and that the abutment block 24 can form an interference fit with the inner wall of the slot 12, ensuring the reliability and effectiveness of the temporary fixation of the lampshade 2 and base 1 during assembly, and providing conditions for ensuring the subsequent ultrasonic welding effect.

[0026] The high-sealing vehicle lamp provided in this embodiment includes a base 1, a lamp cover 2, and a lighting assembly 3. A first welding portion 11 and a second welding portion 21 are respectively provided on the lamp cover 2 and the base 1, located on opposite sides of each other. The first welding portion 11 and the second welding portion 21 are ultrasonically welded to form a welded structure at the connection between the base 1 and the lamp cover 2. This ensures a seamless connection between the base 1 and the lamp cover 2, guarantees consistent connection strength at all points, and improves the sealing performance of the vehicle lamp. Furthermore, it eliminates the need for connecting screws, effectively avoiding the problems of needing connecting holes on the lamp cover 2 and the base 1 that affect structural strength and sealing performance. This not only improves sealing performance but also ensures aesthetics, resulting in a higher quality vehicle lamp.
