DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0035] like Figure 1 , Figure 2As shown, this embodiment proposes that the present application provides an ultrasonically welded headlight, which can be tied to a bicycle or other vehicle to provide lighting or nighttime light reminders. The ultrasonically welded headlight of this embodiment mainly includes: a bottom shell 100, a light panel 300, and a front shell 200. The outline of the entire ultrasonically welded headlight is a rectangle. For the convenience of structural description, the direction where the bottom shell 100 is located is the bottom, and the direction where the front shell 200 is located is the top. The direction where the long side of the rectangular headlight is located is the length direction, which is also the front and rear direction; the direction where the short side is located is the width direction, which is also the left and right direction. The bottom shell 100 includes an outer rib 110, and the outer rib 110 surrounds the installation cavity 120; the outer rib 110 can be arranged around the outer circumference of the bottom shell 100, so there are outer ribs 110 in the front, rear, left and right directions, so that the top of the installation cavity 120 is open. A plurality of support platforms 130 are arranged in the installation cavity 120. The plurality of support platforms 130 can be distributed in a circle. For example, support platforms 130 can be arranged on both sides of the length direction or / and both sides of the width direction in the installation cavity 120, and the support platforms are located on the inner side of the outer rib 110, so that the plurality of support platforms 130 are arranged at intervals with the outer rib 110 and form a docking groove 121. In this way, the inner wall of the outer rib 110 and the side wall of the support platform 130 facing the outer rib 110 respectively form the two side walls of the docking groove 121, and the bottom surface of the edge of the installation cavity 120 forms the bottom surface of the docking groove 121. The lamp board 300 is located in the installation cavity 120 and abuts against the support platform 130. In the specific structure, the upper surface of the support platform 130 abuts against the back of the lamp board 300, so that the support platform 130 provides a bearing position for the lamp board 300, and can also provide an installation position for the lamp board 300, thereby facilitating the positioning and installation of the lamp board 300. A docking rib 210 is provided at the edge of the face shell 200. The docking rib 210 is located on the lower surface of the face shell 200 and extends vertically downward. The docking rib 210 is also arranged around the face shell 200 in a full circle. When the face shell 200 is installed on the bottom shell 100, the docking rib 210 is inserted into the docking groove 121 to limit the face shell 200 and the bottom shell 100. The positions of the face shell 200 and the bottom shell 100 in the left and right and front and back directions are basically fixed to achieve accurate positioning. Then, the edges of the face shell 200 and the bottom shell 100 are welded and fixed by ultrasonic welding, thereby achieving fixed installation of the face shell 200 and the bottom shell 100, so that the light board 300 is stably installed in the installation cavity 120. After the light board 300 is powered on, it emits light toward the face shell 200, so that light is transmitted from the upper surface of the face shell 200, and the lighting or / and light reminder function is achieved.

[0036] The ultrasonically welded vehicle lamp proposed in this embodiment forms a docking groove 121 between the support platform 130 and the outer rib 110 by arranging an outer rib 110 and a support platform 130 on the bottom shell 100. When the front shell 200 is connected to the bottom shell 100, the front shell 200 and the bottom shell 100 are accurately positioned by inserting the docking rib 210 into the docking groove 121. In addition, during the installation of the lamp board 300, the support platform 130 can also provide stable support for the lamp board 300. The support platform 130 implements multiple functions, thereby optimizing the internal structure of the lamp shell. After the docking rib 210 is inserted into the docking groove 121 for stable positioning, ultrasonic welding is performed to seal the connection between the bottom shell 100 and the front shell 200, thereby ensuring the sealing effect of the connection between the front shell 200 and the bottom shell 100 and improving the overall consistency of the outer wall of the lamp shell. Moreover, ultrasonic welding is used to replace the traditional screw fixing process. The ultrasonic welding process is relatively simple and easy to automate. It can be used with sensors to continuously monitor the temperature, realize automated production, and improve assembly efficiency. A quick, clean, and effective assembly process is achieved.

[0037] like Figure 1 , Figure 2 As shown, further, the support platform 130 in this embodiment is provided with a guide surface 131 on one side facing the docking groove 121, and the guide surface 131 is inclined to guide the docking rib 210 into the docking groove 121. The guide surface 131 can be formed by chamfering the upper end of the support platform 130 on one side facing the docking groove 121, or by rounding. Therefore, the guide surface 131 can be an inclined surface or an arc surface. When the face shell 200 is installed on the bottom shell 100, if the docking rib 210 on the face shell 200 is not aligned with the docking groove 121, the docking rib 210 first contacts the guide surface 131, and the docking rib 210 slides downward along the guide surface 131 and is guided into the docking groove 121, which facilitates the docking installation of the face shell 200 and the bottom shell 100, and improves the assembly efficiency of the face shell 200 installed on the bottom shell 100.

[0038] like Figure 1 , Figure 2 , Figure 3As shown, further, in this embodiment, at least one pair of support platforms 130 located on both sides in the width direction is provided with a plate body limiting portion 140. The support platforms 130 located on both sides in the width direction and in mirror symmetry are regarded as a pair of support platforms 130. Since the distance in the length direction is long, multiple pairs of support platforms 130 are arranged in the length direction. In this embodiment, among these multiple pairs of support platforms 130, the upper surface of a pair of support platforms 130 protrudes from the other pairs of support platforms 130 in the length direction, and the protruding part is the plate body limiting portion 140. The first limiting grooves 310 are respectively provided on the left and right sides in the width direction of the corresponding position of the light board 300, and the first limiting grooves 310 are matched and connected with the plate body limiting portion 140 to limit the light board 300 in the length direction and the width direction. During the process of installing the light board 300 on the bottom shell 100, the lower surface of the light board 300 is placed against the upper surface of the support platform 130 without the board limiting portion 140, and the support platform 130 with the board limiting portion 140 cooperates with the light board 300 to limit the first limiting groove 310, so that the light board 300 will not move in the front and back or left and right directions.

[0039] like Figure 1 , Figure 3 , Figure 4 As shown, further, the plate limiting portion 140 in this embodiment includes a limiting step 141, which is provided on the side of the support platform 130 away from the docking groove 121, and the limiting step 141 includes a horizontal limiting surface 142 and a vertical limiting surface 143 which are perpendicular to each other, and the horizontal limiting surface 142 is flush with the upper surface of other support platforms 130 which are not provided with the plate limiting portion 140, so as to be used together with other support platforms 130 to support the light board 300. When the first limiting groove 310 cooperates with the plate limiting portion 140, the first limiting groove 310 is sleeved on the support platform 130 to limit the length direction of the light board 300; the vertical limiting surfaces 143 located on both sides in the width direction are respectively located in the first limiting grooves 310 on both sides to limit the width direction of the light board 300.

[0040] like Figure 1 , Figure 3 , Figure 4As shown, further, in this embodiment, at least one pair of support platforms 130 located on both sides in the width direction are provided with limiting posts 150, the limiting posts 150 and the plate limiting portion 140 are respectively located on both sides in the length direction of the installation cavity 120, and the limiting posts 150 are arranged on the upper surface of the support platform 130 on one side in the length direction and extend upward by a predetermined length. Second limiting grooves 320 are respectively provided on the left and right sides in the width direction of the light board 300, and the second limiting grooves 320 are matched and connected with the limiting posts 150. When the second limiting grooves 320 are matched with the limiting posts 150, the second limiting grooves 320 are sleeved on the limiting posts 150, and the inner wall of the second limiting grooves 320 abuts against the outer wall of the limiting posts 150 to limit the length direction and width direction of the light board 300. Thereby, the light board 300 is installed on the support platform 130 more stably.

[0041] like Figure 3 , Figure 4 As shown, further, the outer contours of the first limiting groove 310 and the second limiting groove 320 in this embodiment are different. The use of different outer contours can limit the light board 300 in multiple directions of length and width without being easily displaced. In the specific structure, the first limiting groove 310 of this embodiment is a square opening groove, and the second limiting groove 320 is a semicircular opening groove. The square opening groove is sleeved on the plate limiting portion 140 protruding from the support platform 130, and after matching with the limiting step 141, it limits one end of the length direction of the light board 300; the semicircular opening groove is sleeved on the limiting column 150 protruding from the support platform 130, and after matching with the limiting column 150, it limits the other end of the length direction of the light board 300, which realizes stable limiting while facilitating the installation and disassembly of the light board 300.

[0042] like Figure 3 , Figure 4 As shown, further, the plate limiting portion 140 and the limiting column 150 in this embodiment do not protrude from the notch on the surface of the light board 300. The plate limiting portion 140 and the limiting column 150 are both set relatively low, so that the upper surface shell 200 can press the light board 300, thereby avoiding the interference of the limiting portion and the limiting column 150 in the pressing process of the surface shell 200, so that the surface shell 200 can press the edge of the light board 300, making the installation of the light board 300 more stable.

[0043] like Figure 2 , Figure 3As shown, further, the inner bottom surface of the bottom shell 100 in this embodiment is provided with a lower concave cavity 132, and the inner side wall of the lower concave cavity 132 is spaced a predetermined distance from the inner side wall of the outer retaining edge 110 to form the bottom surface of the docking groove 121, and the support platform 130 is arranged on the inner side wall of the lower concave cavity 132. The support platform is arranged on the inner wall of the lower concave cavity 132, so that the side surface of the support platform 130 is attached to the inner side wall of the lower concave cavity 132 and extends upward and then protrudes from the bottom surface of the docking groove 121, and the lower surface of the support platform 130 is connected to the bottom surface of the lower concave cavity 132, so that both surfaces of the support platform 130 are connected to the shell, so that the resultant strength of the support platform 130 is enhanced, the support platform 130 is not easy to break, the support strength of the lamp board 300 is improved, and the product quality is improved.

[0044] like Figure 1 , Figure 2 As shown, further, the two sides of the face shell 200 in this embodiment are located outside the docking rib 210 and protrude to form a sealing bottom surface 220, and the sealing bottom surface 220 covers the upper surface of the outer rib 110, so that the outer wall of the face shell 200 is flush with the outer wall of the bottom shell 100. In the specific structure, the sealing bottom surface 220 is butted against the upper surface of the outer rib 110 to increase the contact area, thereby making the welding area larger during the ultrasonic welding process and improving the welding firmness. In addition, the outer wall of the face shell 200 is flush with the outer wall of the bottom shell 100 at the connection, so that the overall consistency of the shell after welding is good.

[0045] like Figure 1 , Figure 2 , Figure 3 As shown, further, in this embodiment, the outer retaining edge 110, the mounting cavity 120 and the support platform 130 are integrally formed, and the surface shell 200 is a transparent plastic shell. The integral molding method makes the connection structure strength between the components higher, ensuring the product quality.

[0046] In summary, an ultrasonically welded vehicle lamp in the present application realizes accurate positioning of the front shell and the bottom shell. In addition, during the installation of the lamp panel, stable support for the lamp panel can be achieved, thereby optimizing the internal structure of the lamp housing. Ultrasonic welding is used to seal the joint between the bottom shell and the front shell, thereby ensuring the sealing effect of the joint between the front shell and the bottom shell and improving the overall consistency of the outer wall of the lamp housing. Moreover, the fixing method of ultrasonic welding replaces the traditional screw fixing process, thereby improving assembly efficiency.
